Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

The doctor who mends broken brains: why there is room for hope after a stroke or head injury

 In my 16 years writing this blog, I SEE NOTHING THAT SUGGESTS ANY GUARANTEED WAY TO GET RECOVERY!  Hope is NOT GOOD ENOUGH! Do the work that delivers recovery!

The doctor who mends broken brains: why there is room for hope after a stroke or head injury

The neurologist Orlando Swayne doesn’t suggest everyone can recover.(That's the problem in a nutshell, advocating the tyranny of low expectations to dumb down the survivor goals to what can currently be delivered! THAT IS GIVING UP BEFORE THE SURVIVOR EVEN STARTS! 100% recovery is the only goal in stroke! GET THERE!) But he does argue that early, targeted and intense therapy can sometimes bring about life-changing improvements – and we have a moral obligation to provide it

Claire was in bad shape. She had been brought to the ward on a stretcher and hoisted on to a bed where she lay curled up in a ball. She was unable to speak, her eyes flat and face expressionless. While she could move her right arm a little, her left arm and both legs were immobile.

Life had changed dramatically for Claire, a mother of three in her late 30s, many months earlier, when she collapsed while on a night out with friends. A weakness in an artery at the base of her brain had ruptured, spilling blood around her frontal lobe. She was taken to hospital, where surgeons removed two side plate-sized pieces of bone from her skull to relieve the pressure on her brain. She spent months in intensive care.

Can a patient with such profound impairment improve in any meaningful way, especially so long after the event? That was the question for Orlando Swayne, a consultant neurologist and co-lead of the pioneering neurorehabilitation unit at the National hospital for Neurology and Neurosurgery, a Victorian redbrick building in Queen Square, central London.

(If your doctor doesn't reference 

 Pedro Bach-y-Rita  who recovered fully back in 1958 with only a partial brain! Aren't you smart enough to duplicate that? Then you DON'T have a functioning stroke doctor! Get rid of them!) 

It was a few years before the pandemic when Swayne first met Claire on the ward. She made eye contact but showed no other response. He knew from the referring hospital that she could write single-word answers to queries, but these revealed characteristic signs of the brain damage she had sustained. Before leaving her bedside to tend to other patients, Swayne asked if she had any questions. With a pencil clenched in her right hand, she wrote: “Questions, questions, questions,” and then tailed off into a wiggly line. The pathological repetition comes from a failure in the frontal lobe to keep actions moving along in sequence.

“There are some patients who start off, when we first work with them, severely impaired – and I mean very severely impaired,” says Swayne. Claire (not her real name) was one such patient.

If he had trusted only his lectures at medical school, Swayne might have considered Claire beyond help. Dogma held that broken brains didn’t mend. A brief flirtation with neurosurgery did nothing to dispel the view. “You see patients in a really terrible state and you think that’s them for life,” he says, “but you don’t see them for very long.”

You see patients in a really terrible state and you think that’s them for life

Swayne quickly decided against a career in neurosurgery, perhaps for the best. “I’m a bit clumsy,” he says, though this wasn’t the only reason. “Neurosurgery is all about the craft, and I’m not really a craft person. I like the people. I like the relationships and the human aspects, which you don’t get so much in neurosurgery.”

He moved into general medicine, then into neurology and stroke medicine, and over the next 20 years or so started to see patients long after their original admission. “I began to realise that some of these patients were improving. And the ones who were improving were the ones working with therapists,” he says. “I thought: ‘OK, I didn’t realise that was a thing. How does it work?’”

The answer, it seems, is to be found in the brain’s capacity for neuroplasticity, its ability to make new connections and reorganise in the face of changed circumstances. In his new book, How to Use a Fork: Stories of Mending the Broken Brain, Swayne argues that recent discoveries in this area have “profound implications” for patients and the therapy and care we owe them.

Swayne is at the piano murdering Chopin – his words, not mine – when I arrive at his north London home. Our chat clashes with his daughter leaving for gap year travels, a milestone I’d assumed would be infused with chaos, but a calmness prevails. A small black dog bounds over and then scoots away, before finding a spot on the kitchen sofa.

My copy of his book is a mess of folded corners, underlined passages and notes in the margin, but I confess, unfairly in retrospect, that I hadn’t relished reading it. For there is history here. Doctors have written books on neuroplasticity before and some made me deeply uncomfortable. To my mind, they peddled false hope through portrayals of miraculous recoveries. At worst, they seemed to imply that patients with severe brain injuries could rise up from their wheelchairs, speak fluently once again and overcome deep cognitive impairment if only they put their mind to it. I feared more of the same: show me a publisher that wants stories of patients whose lives are destroyed and remain so.

Swayne, it turns out, has read the same books and shares the concern. To be clear, he is not suggesting that everyone who suffers a huge stroke or brain injury can recover. His argument is that early, targeted and intense therapy can bring about life-changing improvements, and that we have a moral obligation, not to mention an economic one, to provide such care. “The perception of brain injury is that it is irreversible and irrecoverable from, and this is a corrective to that view,” he says. “There is hope, but clearly you have to balance that. Some people just don’t recover.”(Discounting 

 Pedro Bach-y-Rita  who recovered fully back in 1958 with only a partial brain!)

Stroke is a leading cause of adult disability in the UK. It happens when a blood vessel, typically an artery, becomes blocked or bursts, and starves the brain of oxygen and nutrients. Within minutes, brain cells in the affected region begin to die. Depending on the location, a stroke can cause paralysis, loss of speech, blindness and other vision problems, impaired thinking, memory loss, personality changes, an inability to swallow, and more. Of the 12 million or so people globally who suffer a stroke each year, one in five dies within 30 days.

Many stroke patients show small improvements in the first few weeks, as swelling and inflammation subside. According to old-school thinking, that was as much as you could hope for. But it’s not the full story. The damage caused by stroke or brain injury drives chemical changes in the brain. These trigger neuronal growth processes that were last active in the developing brain. Surviving neurons are spurred into making new connections and to work around the dead tissue.

Of course, the brain constantly demonstrates some level of neuroplasticity. To learn a foreign language, or how to play a new instrument or fly a helicopter, your brain must forge new connections. The process redraws the functional maps in the brain, the neural territory called upon to perform particular tasks. So it is that black-cab drivers in London have more grey matter in the hippocampus after learning the Knowledge. Likewise, the amount of brain dedicated to using the index finger expands when people learn to read braille with it. But the process is sluggish in adults compared with children and those who have suffered recent stroke or brain injury.

After such events, neuroplasticity ramps up for several months. This is when intense, targeted therapy can have the most impact. “Even though the capacity for plasticity is greatest in the first few months, it doesn’t just switch off,” Swayne says. In one study, intensive therapy improved upper limb movement in patients 18 months after their strokes.

Claire’s early therapy sessions focused on positioning and stretching – to enable her to sit comfortably – and mouth, tongue and voice box exercises. But they were tough, and she quickly became too tired to continue. In time, though, her stamina improved and she engaged more with the therapists. Her gaze began to follow people walking past and she would sometimes move her mouth to speak in response to questions.


Her improvement gathered pace with music therapy. In those sessions, Claire used her stronger right hand to pluck guitar strings and shake maracas. Her therapists noticed more spontaneous facial expressions and she began to point to instruments, choosing, being proactive. Session after session, for four months, she was drilled to make choices, identify objects, to engage her mouth and tongue.

Swayne hadn’t caught up with the therapists in a while, but one day as he headed past Claire’s bay and said hello, she looked up and said: “What happened to your hair?” Swayne stopped dead. “That was an amazing moment,” he says. “If you work with a patient who’s not spoken for a year, and you do an intervention and they start speaking, it’s got to be a response to the therapy.”

Swayne confided in Claire about his disastrous encounter with a barber and later learned from the speech therapist that her language had been coming for a week or so. First it was single words, then phrases and short sentences. She had made progress with her right hand, too. Before long, she was playing Connect 4 with her boys and fellow patients on the ward, though her left side and right leg remained lifeless.

“She started communicating with her kids and with us, and that was enormous,” Swayne says. “Her left side will always remain weak because it’s very badly damaged, but she started using her right arm to do things, like use a phone and use a power chair. We had her cooking, and that was huge. She will always need help, but for quality of life it was transformational.”

There’s plenty still to learn about the brain’s ability to work around dead tissue, but details of some mechanisms are emerging. Delve into the motor cortex in the brain’s frontal lobe and you’ll find specialised neurons that drive limb movement. These are arranged vertically to send their messages to the spinal cord. But they are also linked by a mesh of horizontal connections. Normally, these horizontal connections are suppressed, but in the event of brain damage, the inhibition is relaxed and the connections activate. Surviving neurons can now recruit neighbours to their cause, though they need time and training to learn the new job.

There’s more to neuroplasticity than this, but the mechanism explains some of the stark limitations that doctors and their patients witness. When neural connections are completely lost, it seems no amount of therapy can bring them back. And while the brain can reorganise to some extent, there’s no evidence that a specialised region of the cortex can take on an entirely different role. If a stroke leaves your right arm limp, your visual cortex cannot take control of it any more than your kettle can make the morning toast. That said, movement, language, sensation and vision are not confined to small brain regions: they are distributed across networks that provide for some flexibility. For example, most people do the bulk of their language processing in the left side of the brain, but if it is damaged, there’s evidence that parts of the language network on the right side can take on some of the work.


Much of the immediate work with new stroke patients is to identify their impairments and the causes. If they are unable to use a fork, what is stopping them? Can they feel it? Are they too weak on that side? Can they coordinate their movements?

Therapists take impairments and break them down into steps that patients can be drilled on. There is, so far, no shortcut to the gruelling hours put in by the patients described in Swayne’s book. Thomas, a vicar who couldn’t speak after a stroke at the pulpit, had intensive speech therapy to retrain his swallowing and tongue movements. Christian, a mixologist at a swanky London hotel, relearned how to brush his teeth: turn the tap on, get the toothbrush, add the toothpaste. Vikas, a roofer who fell from three storeys up, had sessions in the kitchen to learn how to pay attention and multitask again.

It’s not just the direct damage that therapists have to contend with. The brain can create its own problems. Patricia, a catering assistant, had lost the use of her right arm. When asked to point to it, she would move it out of the way and keep searching among the bedclothes. She later believed the arm was a baby and became inconsolable when she thought it had died.

The therapy a patient receives after stroke is the most important determinant of how well they recover: will they be dependent on others or able to fend for themselves? Yet what most patients receive is grossly inadequate, Swayne says. Every working day, patients at stroke units in the UK should receive 45 minutes each of physio, occupational therapy and speech therapy. In 2020, an audit found that most patients received only 14, 13 and seven minutes per day, respectively. “It’s shocking,” says Swayne.

It is even worse when people leave hospital. Stroke units used to pass patients on to the community therapy team in their local area, but those networks were demolished by austerity economics. “It’s a real postcode lottery. There are some boroughs where you’re relieved you’re discharging the patient to that borough because they’ve actually got a speech therapist, whereas another borough is a desert,” Swayne says. “It’s frustrating, having worked with these patients for months, to then send them into the wilderness.” It’s common for patients to return a year or two later with complications, having had no therapy since leaving hospital.

The argument that proper rehabilitation is a luxury we cannot afford does not add up, Swayne adds. Early intensive therapy pays for itself by reducing the cost of long-term care. This will become ever more important as first-time strokes rise in the coming years. Today, strokes cost the UK economy an estimated £27bn a year, but only £3bn of that is driven by direct hospital care. The rest is lost economic productivity and the invisible costs of care. By 2035, the cost is predicted to more than triple to £75bn.

“People talk about the cost of these interventions, but if you do the maths, an admission might cost something like £40,000,” Swayne says. “That sounds like a lot of money, but if you look at the change in care costs, it isn’t, because it pays itself back pretty quickly.” Swayne did the sums for one patient: during his time in the rehabilitation unit, his care costs fell to £2,640 per week, meaning the cost was offset within four months of him going home, and would save tens or hundreds of thousands of pounds in the longer term.

uble. Care for traumatic brain injury is also badly neglected. Each year, more than 1 million people in England and Wales attend emergency departments for head injuries. Of the 200,000 or so who are admitted to hospital, about 40,000 have evidence of traumatic brain injury.

Many such patients are discharged within a couple of weeks. Superficially, they seem better: they can walk and talk. But often, important problems are simply not spotted. “What we now realise is that a majority of those patients have got cognitive changes that haven’t been picked up,” Swayne says. “You can see them walking down the street and they look fine, but they cannot function normally. There’s an invisible disability. It affects their relationships, their employment and they get into trouble with the police.”

And so, the hidden damage left by brain trauma can lead to lives falling apart. In one 2025 study, researchers found that nearly 90% of adult men in Scottish prisons had experienced severe head injury. That doesn’t mean that brain injury triggered their crimes: violent men experience more violence. But damage to specific brain regions might contribute to criminal behaviour, by making it harder for people to control their impulses, feel empathy and anticipate the consequences of their actions.

Researchers are looking at ways to make therapy more effective and – the holy grail – to reopen the window of enhanced neuroplasticity. New drugs, brain stimulation and virtual reality are all in the mix. If they succeed, patients could receive more beneficial therapy to boost their recovery. But for now, perhaps the best we can do is keep our brain healthy and protected.

“We all know what to do for brain health,” says Swayne. “We should exercise. We should be in a stimulating environment and have social interactions. We shouldn’t smoke or drink too much alcohol. There’s really strong evidence that all these things help with brain maintenance. By looking after your brain you’re giving yourself the best chance of recovery should you need it.”

Hope and the Life Course: Results From a Longitudinal Study of 25,000 Adults

 Did your competent? doctor leave you with any hope at all of having a good life post stroke? NO? So, complete fucking failure of your doctor!

Hope and the Life Course: Results From a Longitudinal Study of 25,000 Adults

First published: 07 October 2025

ABSTRACT

This paper reports the first large-scale longitudinal links between one of the least known dimensions of wellbeing—hope—and long-term outcomes in a range of life arenas. Hope has agentic properties which are relevant to people's future outcomes. Following 25,000 randomly sampled Australian adults over a period of 14 years from 2007 to 2021 (N > 115,000), we find a strong link between hope and better contemporary and future outcomes. Individuals with high levels of hope had improved later wellbeing, education, economic and employment outcomes, perceived and objective health, and are less likely to be lonely. Hope is associated with higher resilience, ability to adapt, and internal locus of control. It also serves as a psychological buffer during bad times. Respondents with high levels of hope were less likely to be influenced by negative life events and adapted more quickly and completely after these major events. Better understanding the drivers and consequences of hope can ultimately inform public policy to improve people's lives.

Long-term MIND Diet Commitment Key to Boosting Brain Health

But there is nothing EXACT  about this diet so nothing is scientifically repeatable so you can't be sure that your dementia risk declines.  A diet protocol is needed instead of hope that something works.

Long-term MIND Diet Commitment Key to Boosting Brain Health

Summary: A recent study unveils the significance of long-term commitment to the MIND diet in enhancing brain health.

The first randomized clinical trial of its kind, the study observed that short-term cognitive improvements were seen within the first two years, however, no significant difference was noted between the MIND diet and a calorie-restricted control diet over a three-year period. Despite this, the researchers underline that the benefits of the MIND diet likely emerge over a longer period, consistent with earlier observational data.

The MIND diet has been celebrated for its positive effects on brain health, slowing cognitive decline and reducing Alzheimer’s risk.

Key Facts:

  1. The three-year clinical trial showed cognitive improvements in the initial two years for the MIND diet group, but no significant difference when compared to the control diet group by the end of the study.
  2. The study, the first randomized clinical trial designed to test the effects of a diet on cognitive abilities, enlisted individuals 65 years or older without cognitive impairment.
  3. The MIND diet, a combination of the Mediterranean and DASH diets, has been ranked among the top five diets by U.S. News & World Report for six consecutive years.

New research shows the importance of long-term commitment to the MIND diet for reaping the greatest benefit to brain health.

“The benefits within the new study’s three-year clinical trial weren’t as impressive as we’ve seen with the MIND diet observational studies in the past, but there were improvements in cognition in the short-term, consistent with the longer-term observational data,” said lead study author Lisa Barnes, PhD, associate director of the Alzheimer’s Disease Research Center at RUSH.

Results from the study, published in The New England Journal of Medicine, showed that within a three-year period, there was no significant statistical difference in change in cognition for participants in the MIND diet group compared to the usual diet control group; both groups were coached to reduce calories by 250 kilocalories per day. But there was a significant improvement during the first two years of the study.

“What we saw was improvement in cognition in both groups, but the MIND diet intervention group had a slightly better improvement in cognition, although not significantly better,” Barnes said.

“Both groups lost approximately 5 kilograms over three years, suggesting that it could have been weight loss that benefited cognition in this trial.”

‘Exciting’ improvement

This is the first randomized clinical trial designed to test the effects of a diet thought to be protective for brain health, on the decline of cognitive abilities among a large group of individuals 65 years or older who did not have cognitive impairment. The MIND diet has been ranked among the top five diets by U.S. News & World Report annually for the last six years.

“There is established research that shows that a person’s diet affects health,” Barnes said. “The participants in this study had to have sub-optimal diets as determined by a score of 8 or less on a diet screening instrument before the study even began. It is reasonable to think that either they were going to maintain their cognition or decrease the rate of cognitive decline in the future.”

“It was exciting to see that there was improvement in cognition over the first year or so, but it could have been due to practice effects on the cognitive tests, and we saw it for the control diet as well, which focused on just caloric restriction.”

Previous research by the late Martha Clare Morris, ScD, showed that there was a slower rate of decline among those who ate specific foods. Morris was a nutritional epidemiologist at RUSH and the original principal investigator of the MIND diet study that was funded by a $14.5 million National Institutes of Health grant and involved two clinical sites, RUSH in Chicago and Harvard School of Public Health in Boston.

In 2015, Morris and her colleagues at RUSH and Harvard University developed the MIND diet — which is short for Mediterranean-DASH Intervention for Neurodegenerative Delay — in preparation for the trial.

The diet is based on the most compelling research on the foods and nutrients that affect brain health. As the name suggests, the MIND diet is a hybrid of the Mediterranean and DASH (Dietary Approaches to Stop Hypertension) diets.

Both diets have been found to reduce the risk of cardiovascular conditions, such as hypertension, diabetes, heart attack and stroke. In two studies published in 2015, Morris and colleagues found that the MIND diet could slow cognitive decline and lower a person’s risk of developing Alzheimer’s disease significantly, even if the diet was not followed meticulously.

Study tracked 604 participants over three years

The latest trial of the MIND Diet for Prevention of Cognitive Decline in Older Persons, was a randomized, Phase III trial that enrolled 604 people who were overweight and had a suboptimal diet and a family history of Alzheimer’s disease. 

The trial compared two different diet interventions, both of which included dietary counseling with mild calorie restriction of 250 calories per day for weight loss.

Participants of both groups had individualized diet guidelines developed by dietitians, and they received regular phone and in-person consultations, as well as occasional group sessions over the three-year life of the study.

Participants were seen five times during the three years to evaluate their mental abilities, blood pressure, diet, physical activity, health conditions and medication use.

“Both groups of participants got a lot of support and accountability by trained registered dietitians,” said Jennifer Ventrelle, assistant professor in the Departments of Preventive Medicine and Clinical Nutrition and lead dietitian on the MIND diet trial at RUSH.

“The good news is that this helped all participants improve on average, but unfortunately hindered the ability to detect significant differences between the two groups in this relatively short period of time.

“Current and future research plans to look at people coached to follow the diet in this format compared to individuals following a usual diet in a format closer to usual care such as brief clinical encounters or a self-guided program with less support.”

“By the end of the study, the average weight loss was approximately 5.5% of initial body weight for all participants, exceeding the study target of 3%, the amount recognized as clinically significant to prevent or improve adverse health outcomes,” Ventrelle said.

“The average MIND score at the end of three years for the MIND group was 11.0 and 8.3 for the control group, placing both groups in a therapeutic range to slow cognitive decline and lower a risk for Alzheimer’s disease, according to previous studies.

“The significant weight loss and improved MIND scores suggest that the control group also improved their diet and may suggest that following the MIND diet at a score of at least 8.3, coupled with at least a 250 calorie reduction to produce weight loss, may improve cognition. More research is needed to confirm this.”

Fish, chicken, berries, nuts and leafy greens

The MIND diet has 14 dietary components, including nine “brain-healthy food groups” – such as chicken and fish, green leafy vegetables and berries, and nuts – and five unhealthy groups: red meat, butter and stick margarine, full fat cheese, pastries and sweets, and fried foods.

“Randomized trials are gold standards for establishing a cause-and-effect relationship between diet and incidence of Alzheimer’s disease,” Barnes said.

“These individuals were healthy at the start of the trial and had no cognitive impairment, and their cognition got slightly better over time,” Barnes said.

“Why there was no difference between the two diet groups at the end of the trial could be a result of many factors including that the control group had a relatively healthy diet.

“Moving forward, we will look at specific food groups and their associations with biomarkers that were measured in the blood to see if certain nutrients and food groups are more important than others since the two groups were pretty healthy from a dietary perspective at the start.”

How VR is Transforming the Landscape of Stroke Rehabilitation

But you tell us NOTHING FACTUAL ABOUT RECOVERY RESULTS! Useless!

Hope is not something survivors want. They want you to provide EXACT 100% RECOVERY PROTOCOLS! GET THERE! 

How VR is Transforming the Landscape of Stroke Rehabilitation

The revolutionary impact of Virtual Reality (VR) on stroke rehabilitation is a testament to the rapid advancements in technology and its application in the medical field. This comprehensive overview aims to shed light on how VR is transforming the landscape of stroke rehabilitation, offering a new dimension of hope for patients and healthcare providers alike.

Stroke rehabilitation has traditionally been a long and arduous process, often involving repetitive physical exercises to regain lost motor skills. However, the advent of VR technology has brought about a paradigm shift in this area. VR provides an immersive, interactive environment that can simulate real-world activities, making the rehabilitation process more engaging and less monotonous for patients.

The use of VR in stroke rehabilitation is grounded in the concept of neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections. By immersing patients in a virtual environment, VR stimulates the brain in a way that traditional therapy cannot. This high level of stimulation encourages the brain to form new connections, thereby aiding in the recovery of motor skills lost due to stroke.

Moreover, VR offers a level of customization that is unparalleled in traditional therapy. Therapists can tailor the virtual environment to each patient’s specific needs and progress, making the rehabilitation process more efficient. For instance, a patient struggling with hand movements can be immersed in a virtual environment that requires them to perform tasks involving those specific movements. As the patient’s skills improve, the difficulty level of the tasks can be gradually increased, providing a constant challenge and promoting continuous improvement.

Another significant advantage of VR is its ability to provide immediate feedback. Patients can see their progress in real-time, which can be a powerful motivator. This immediate feedback also allows therapists to adjust the therapy program as needed, ensuring that the patient is always working towards their rehabilitation goals.

Furthermore, VR can make the rehabilitation process more accessible. With the advent of affordable VR headsets, patients can continue their therapy at home, reducing the need for frequent hospital visits. This not only makes the rehabilitation process more convenient but also allows for more consistent therapy, which can lead to better outcomes.

Despite the promising potential of VR in stroke rehabilitation, it is important to note that it is not a standalone solution. It should be used as a supplement to traditional therapy, not a replacement. While VR can provide a high level of stimulation and customization, it cannot replace the hands-on care and expertise provided by healthcare professionals.

In conclusion, VR is revolutionizing the landscape of stroke rehabilitation, offering a more engaging, efficient, and accessible approach to therapy. By harnessing the power of VR, healthcare providers can provide better care for stroke patients, helping them regain their lost motor skills and improve their quality of life. As technology continues to advance, the potential of VR in stroke rehabilitation is likely to grow, opening up new possibilities for patient care and recovery.

Four popular diets may reduce dementia risk

But there is nothing EXACT  about these diets so nothing is scientifically repeatable so you can't be sure that your dementia risk declines.  A diet protocol is needed instead of hope that something works.

Four popular diets may reduce dementia risk

Key takeaways:

  • Greater adherence to a healthy plant-based diet or Mediterranean diet, among others, was linked to larger brain volumes.
  • The findings highlight the benefits of a healthy diet for dementia prevention.

Following a healthy plant-based diet, Mediterranean diet, the MIND diet or having a high recommended food score at midlife was associated with a reduced risk for dementia, according to research in the American Journal of Clinical Nutrition.

Previous studies on connections between dementia risk and dietary patterns are limited and inconsistent, Jingyun Zhang, a postdoctoral research associate with Zhejiang University School of Medicine in China, and colleagues wrote.

“There were more than 55 million people living with dementia worldwide in 2021, and this number is expected to increase by 10 million per year,” they wrote. “Dementia increases the risk of poor patient-centered outcomes, which include CVDs, disturbed emotions, death, depression and limited social interactions. Thus, proper preventive and management strategies are critical due to the lack of effective treatments for dementia.”

Zhang and colleagues conducted a study to assess the associations of midlife dietary patterns with brain structures and incident dementia.

The researchers evaluated the prospective associations of four healthy dietary pattern indices — the healthy plant-based diet index (hPDI), Mediterranean diet score (MDS), recommended food score (RFS) and Mediterranean-Dietary Approaches to Stop Hypertension Intervention (DASH) Intervention for Neurodegenerative Delay Diet (MIND) — with incident dementia. They identified dementia using linked hospital data of 11,684 people from the U.K. Biobank. The researchers then used linear regressions to investigate cross-sectional associations of these dietary pattern indices with brain structures.

The hPDI is an “innovative dietary pattern index” that emphasizes the intake of healthy plant foods linked to improved health outcomes. Recent research has indicated that this dietary pattern may lower the risk for mortality and major chronic conditions and has low greenhouse gas emissions.

The MDS is a nutrient- and food-based nine-item score that reflects Mediterranean diet adherence. The Mediterranean diet has been named best overall diet for six consecutive years and has been linked to several health benefits such as reduced risk for CVD, adverse pregnancy outcomes and total mortality.

The RFS measures overall dietary patterns based on the intake of five food components the Dietary Guidelines for Americans recommend. Finally, the MIND index is a combination of the DASH diet and Mediterranean diet that specifically focuses on brain health.

Zhang and colleagues found that greater adherence to hPDI, MDS, RFS and MIND was individually linked to larger brain volumes in specific regions. These findings, they wrote, provide a comprehensive picture of the consistent associations between midlife dietary patterns and brain health and highlight the benefits of a healthy diet for dementia prevention.

In the average 9.4-year follow-up, 0.42% of participants developed dementia, and all dietary patterns offered protective effects against incident dementia, but the associations were not statistically significant, according to the researchers.

“We speculate that a potential mechanism for the benefit of healthy diets in preventing dementia is that adherence to healthy diets may increase brain volume,” they wrote. “The most extensively influenced regions include the parietal and temporal cortices and the hippocampus.”

When it came to brain structure, the researchers found that higher dietary pattern indices were significantly linked to larger regional brain volumes, including volumes of the hippocampus and thalamus and volumes of gray matter in the parietal and temporal cortices.

“These findings highlight the importance of midlife dietary patterns in maintaining brain health and thereby preventing dementia,” Zhang and colleagues concluded. “From a public health perspective, preventive and interventional dietary strategies could counter the growing burden of dementia in aging populations, which may be effective even in resource-limited settings.”

IV thrombolysis may be safe in patients with ischemic stroke aged 90 years or older

What is your doctor doing to prevent this intracranial hemorrhage? NOTHING? Just hoping for the best? Then you don't have a functioning stroke doctor or hospital!

IV thrombolysis may be safe in patients with ischemic stroke aged 90 years or older 

The odds of 3-month symptomatic intracranial hemorrhage following IV thrombolysis for ischemic stroke among patients aged 90 years or older were not greater compared with younger patients, researchers reported.

“Higher probability of death and poor functional outcome during follow-up in the very elderly seems not to be related to IV thrombolysis (IVT) treatment. Very high age itself should not be a reason to withhold IVT,” Valerian L. Altersberger, MD, of the Stroke Centre and department of neurology at the University Hospital Basel and University of Basel, Switzerland, and colleagues wrote.

Current IVT guidelines recommend IVT for patients with ischemic stroke who are > 80 years old. However, this recommendation is not based on evidence from any studies focusing on IVT in very elderly patients,” the researchers wrote.

The TRISP registry

Researchers used data from the Thrombolysis in Ischemic Stroke Patients (TRISP) registry to evaluate the 3-month safety of IVT in patients aged 90 years or older. Patients were compared with a younger cohort (< 90 years) for outcomes including intracranial hemorrhage, death and poor functional outcome at 3 months.

Poor functional outcome was defined as 3-month modified Rankin Scale score of 3 to 5 among patients with a before-stroke score of 2 or less, or a 3-month score of 4 to 5 in patients with before-stroke score of 3 or more.

Among 16,974 patients included in the analysis, 5.7% were aged 90 years or older.

Those aged 90 years or older were more often women, were more likely to have a before-stroke modified Rankin Scale score of 3 or more, and had higher NIH Stroke Scale score, BP, glucose and creatinine levels at hospital admission for stroke compared with the younger group.

Researchers reported that the likelihood of intracranial hemorrhage at 3 months was not significantly greater between the older and younger groups (older, 5.7%; younger, 4.4%; adjusted OR = 1.14; 95% CI, 0.83-1.57). However, the odds of death (aOR = 3.77; 95% CI, 3.14-4.53) and poor functional outcome at 3 months (aOR = 2.63; 95% CI, 2.13-3.25) were greater among patients aged 90 years or older compared with younger patients.

After adjustment for confounders, the probability of functional improvement after 24 hours did not differ among patients aged 90 years or older compared with younger patients (aOR = 0.85; 95% CI, 0.7-1.04), according to the study.

Plateau after 79 years

In a post hoc analysis in which patients were stratified by age, researchers observed the rate of symptomatic intracranial hemorrhage increased with every 10 years until patients were aged 70 to 79 years, after which point the rate of symptomatic intracranial hemorrhage remained stable.

“As expected, patients 90 years had more severe strokes, more often relevant prestroke disability and were more likely to have cardiovascular risk factors compared with patients < 90 years,” the researchers wrote. “Consequently, patients 90 years died more often during follow-up and had poorer functional outcomes even after adjustment for potential confounders.

“[A]lthough widely accepted risk factors for symptomatic intracranial hemorrhage were more frequent in the very elderly ... the probability of symptomatic intracranial hemorrhage after IVT did not differ significantly between patients 90 and < 90 years in our study. However, when analyzing the age-dependent probability for symptomatic intracranial hemorrhage by decade, the probability increased up to 70 to 79 years and plateaued for higher age, which might reflect a ceiling effect of symptomatic intracranial hemorrhage after the age of 70 in our cohort.

Key take home messages

  1. Clinically meaningful improvements are possible in chronic stroke patients
  2. The dose of rehabilitation treatment needs to be larger than currently delivered
  3. Rehabilitation is a complex intervention that cannot be reduced to a single element

Somewhere between 50-80% of stroke survivors have upper limb symptoms after acute stroke1 and persistent difficulty in using the upper limb is a major contributor to ongoing physical disability.2 A commonly held view is that most recovery from stroke occurs over the first three to six months after which little improvement is possible, especially at the level of impairment.3-6 We argue that this may be a self-fulfilling prophecy resulting in lack of provision of potentially helpful rehabilitation.

What is the best way to promote upper limb recovery after stroke? Most studies of behavioural interventions have investigated forms of constraint induced movement therapy (CIMT),7,8 repetitive task training (RTT)9 or robotics,10 each of which focuses on increasing the activity of the affected limb. Kwakkel et al8 suggested that motor function, arm-hand activities and self-reported arm-hand functioning in daily life, improved immediately after CIMT and at long-term follow-up, but the comparison was often with usual care. It is worth noting that CIMT approaches were said to be more likely to be successful in promoting long term benefits if the protocol included shaping, massed practice and a behavioural transfer package, whereas simple forced use therapy was ineffective.8 RTT also has some evidence to support benefits over what is described as usual care, but the evidence for benefits over ‘matched therapy’ is less strong.9 The use of robotics can increase the number of movement repetitions, but has failed to produce clinically meaningful effects.10 Indeed, the recent RATULS study showed that compared with usual care, approximately 23 hours of robot-assisted training and matched dose ‘upper limb therapy’ did not improve upper limb function.11 Overall, it would appear that asking patients to make simple repetitions of movement, however meaningful the task, is relatively ineffective without some way of actively translating any improvements into activities of daily living. Simply increasing the number of repetitions does not appear to be effective,12 and this in itself should give us pause for thought.

A few studies have tested more complex therapies incorporating a number of different elements. The ICARE study13 of upper limb treatment after stroke went beyond simple repetitions, using a structured, task-oriented motor training programme that was impairment focused, task specific, intense, engaging, collaborative, self-directed, and patient centred, starting about six weeks post-stroke. Outcomes were not improved by this approach, but on reflection it is likely that, as with many of the studies, the dose of 30 hours over ten weeks was too low (the usual care group received 11.2 hours over ten weeks). Despite scepticism that stroke patients would be able to ‘tolerate’ much higher doses,12 one study managed to deliver 300 hours of upper limb therapy to chronic stroke patients over twelve weeks and reported changes in measures of both impairment and activity that were far greater than those in lower dose studies,14 and in fact the findings of this study have recently been replicated by the same group.15 We recently reported the findings of the Queen Square Upper Limb (QSUL) Neurorehabilitation programme,16 a single centre clinical service that provides 90 hours of treatment focusing on the post-stroke upper limb. Most patients entering the programme were in the chronic stage (> 6 months post-stroke), but were able to complete the 90 hours of the programme, even though they exhibited a wide range of impairments and fatigue levels. Despite the time since stroke (median = 18 months) we observed (i) large clinically meaningful improvements in upper limb impairment and activity (of a magnitude similar to those reported by McCabe et al.), and importantly (ii) that these changes were maintained, or even improved upon, six months after treatment.

The first lesson to take from these studies is that post-stroke rehabilitation programmes and clinical trials are almost certainly under dosing patients. In future, clinical trials must investigate the effects of much higher doses than are currently being used. The second question to be raised is what are the key ‘active ingredients’ of an upper limb rehabilitation treatment? Whilst it is not clear what the optimal behavioural approach for promoting upper limb recovery should be, it is clear that simple protocol driven approaches have not led to large or sustained effects,17 both of which are necessary to produce a step change in stroke recovery. Successful post-stroke neurorehabilitation is likely to require a combination of complimentary approaches. If we accept this premise, then we are unlikely to determine the optimal combination of active ingredients simply by studying each approach in isolation, because the interactions between these elements will also have to be considered.

So how do we work out what the ‘active ingredients’ of upper limb rehabilitation are? A more sensible way forward is to look at interventions that have already demonstrated a high level of efficacy and then begin to work out their key components. Here, it is important to say that we need to start with treatments that have a high chance of achieving minimum clinically important differences (MCID) rather than small changes that might be statistically significant. Both McCabe et al14 and Daly et al,15 as well as the QSUL programme,16 produced large improvements on both impairment and activity limitation and both involved more complex treatment approaches, not restricted to one element. It is worth considering these in more detail.

  • Analysis of movement and performance in activities of daily living. The initial assessment is crucial. The question, ‘why does this person’s hand and arm not work’ should never be answered with ‘because they have had a stroke’. There needs to be an appreciation of the range of potential contributory impairments (patterns of weakness, spasticity, loss of joint range, shoulder restriction and pain, sensory loss, apraxia, cognitive deficits, depression, apathy, fatigue etc.) because each of these becomes a therapeutic target. Our view is that without informed clinical reasoning based on the presence or absence of specific impairments, the correct treatment approach is unlikely to be selected.
  • Identify and treat barriers. Avoid complications that will prevent participation in an active rehabilitation programme. We commonly see loss of passive joint range preventing people accessing finger or thumb movement, due to either spasticity or non-neural shortening. This can happen at most joints, but particularly in the hand. As well as increased finger flexion, be alert to loss of flexion at MCP joints which makes it difficult to shape the hand properly. Treatment involves splinting and optimal spasticity management. We also see pain and restriction of range in the shoulder. Restriction of external rotation in particular should raise the possibility of adhesive capsulitis. Despite the lack of a clear evidence base for treating post-stroke adhesive capsulitis, anecdotally we have had success with capsular hydrodilatation followed by physiotherapy.
  • Preparation. Manual techniques are used to optimise and improve baseline at an impairment level, for example mobilising joints to improve range, lengthening and strengthening muscles to ensure they are at a biomechanical advantage to generate force, training sensory discrimination and improving postural control and balance.
  • Reduction of impairment and re-education of quality and control of movement within activities of daily living. Individualised meaningful tasks are practiced repeatedly in order to facilitate task mastery with a focus on quality of movement. This is achieved through (i) adaptation of the task, e.g. decomposing tasks into individual components to be practiced; (ii) adaptation of the environment, e.g. fabrication of functional splints and adaptation of tools such as cutlery or screwdrivers, to enable integration of the affected hand in meaningful activities; (iii) assistance, e.g. de-weighting the arm to allow strengthening and training of movement quality and control through increased range.
  • Coaching (involving instruction, supervision, reinforcement) was considered a key component of the QSUL programme, used throughout to embed new skills and knowledge into individual daily routines. Consequently, individuals increase participation and confidence in their desired goals, enhancing self-efficacy and motivation to sustain behavioural change beyond the end of the active treatment period.
  • Sustaining change. Our view is that the approach described, delivered at a high dose is most likely to achieve clinically meaningful improvement together with improved self-efficacy and behaviour change that results in retention of gains or further improvement (something not routinely seen with many upper limb interventions that have been investigated).

Rehabilitation is often criticised for not following standardised approaches that lend themselves to investigation through clinical trials. However, when single elements are then studied in isolation the results are often not clinically meaningful and are not sustained.18,19 Looking at the difference between these approaches and those taken by McCabe et al14, Daly et al15 and QSUL16 should be informative, with a view to formally describing the key elements of a successful treatment. Whilst approaches at the activity and participation level will vary as they are tailored to an individual’s specific meaningful goals, the overall therapeutic approach taken towards specific impairments should be the same across all patients. Ideally, it should be possible to describe the principles of an optimal intervention using a format such as the TIDIER guidelines.18,19

There is a way to go before we can really say we understand both the treatment itself and the effects of the treatment on individuals. This will require careful assessment of both the ‘input’ (the nature of the behavioural intervention) and of the ‘output’ (the resulting behavioural change) at a level of fine-grained detail that is not currently achieved on a regular basis, for example using kinematic20 or neurophysiological21 assessment. In addition, this input-output relationship will be modulated by a number of patient characteristics, which could relate to behavioural characteristics (e.g. severity, presence of multiple impairments) or to biological characteristics (e.g. the nature and extent of brain damage, time since stroke, age, medication).

Overall, our experience suggests that much higher doses and intensity of upper limb neurorehabilitation can be delivered with beneficial effects. We have highlighted the need to consider the dose and the nature of the intervention as well as appropriate patient stratification in informing future clinical trial design.
