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.

A happier retirement contains these 3 elements

 Are you recovered enough to be happy? Or did your incompetent? doctor fail you?

My  resilience story: I would still be leading a life of quiet desperation if still married.

(Life is definitely better as I age, I got divorced enhancing my happiness immeasurably. I'm retired and comfortably well off. And healthy as I can be post stroke. I'm going to live a long time yet.)

A happier retirement contains these 3 elements

What’s the secret of a rich, rewarding retirement?

It’s as simple as ABC: agency, belonging and cause.

That’s how Bruce Feiler, author of “A Time to Gather” and other books, spells out the three factors that give life meaning. “Agency” is wielding power and autonomy in choosing how to live; “belonging” is forging social ties with others; and “cause” is serving a higher purpose.

With these three ingredients in place, the odds of a satisfying retirement soar, he says. By making intentional decisions aligned with your goals and values, leading an active social life and contributing to a cause that elevates your spirit, you’re bound to feel more happy and fulfilled.

“It’s a tool kit for navigating retirement,” Feiler said. “It’s the same for navigating any life transition, like an illness, a move or the loss of a loved one.”

Many retirees struggle to find purpose or structure once they’re done with the routine of a traditional job, which can lead to loneliness and isolation. As people live longer, it’s not unusual for retirement to last 20 to 30 years.

Here’s how to assess how well you know and apply these three critical elements:

Agency: Examine how much control you feel you have over your everyday life. By choosing “what we are, what we create and what we do,” as Feiler says, we’re more apt to serve as our own director, rather than letting external factors direct us.(I'm completely in control, know enough to say no when needed.)

Belonging: Consider the key players in your life. Do you have positive relationships with friends and family? Do you attend community events or other group gatherings eagerly? Or do you feel alone and isolated much of the time?(Have many social groups and travel companions. Marriage  would vastly complicate my social connections.)
Cause: Explore how deeply you believe in something larger than yourself. Does your desire to give back or tackle societal problems energize you? Do you pounce on volunteer opportunities? When donating your time to make a difference or improve the lives of others, do you feel fully alive and happy?

(Trying to get stroke solved to 100% is a humongous challenge! Getting through the fossilized brains of stroke medical 'professionals' I haven't figured out yet. 

And I think a lot of funerals will need to occur before we get the right strategy and leadership to GET THERE!

Even if all three elements are present in your life, try adding more, the author says.

“Pick a personal project for A, B and C,” Feiler said. “I’m tempted to say start small, but some people like to start big.”

To gain more agency, for example, you can tend the garden for an hour or write your autobiography. Let your motivation level determine the size and scope of the project.

At the same time, cut yourself some slack. As you age, you may face limitations on your ability to exert agency, socialize often and embrace a cause.

“The ABCs are very important,” said Teresa Amabile, a professor emerita at Harvard Business School. “But they’re not of equal importance.”

One focus plays a paramount role in enhancing your retirement years: belonging.

The biggest predictor of longevity and happiness is the quality of our relationships, according to the Study of Adult Development, which has tracked participants and their descendants for nearly 90 years.

“Belonging is very critical,” said Amabile, co-author of “Retiring: Creating a Life That Works for You.” “Relationships make a huge difference in life satisfaction. That’s certainly very true in retirement.”

Even if you were somewhat lonely or less satisfied with your past relationships, it’s not too late to find more comradeship and support in retirement. Maintaining an openness to people — and a willingness to strengthen connections with everyone from distant or estranged family members to friends, acquaintances and strangers — enables you to benefit from more social interaction.

The obstacles of the alphabet

It’s not always easy to follow through with your ABCs. Obstacles abound.

Amabile warns that we may lose some agency despite our best efforts.

“There’s only so much control we can exert over our lives and circumstances,” she said. “So it’s necessary to figure out when we can’t control things and find out how to adapt.”

Moreover, it takes confidence and positivity to pilot your life. You need to believe that you can wield control over your choices and resist outside forces that try to influence you.

To forge better social connections, weigh whether shyness, cynicism or snap judgments of others hold you back.

“People have gremlins,” said Barbara Waxman, a San Francisco-based gerontologist and coach. “There are naysayers on our shoulders who hold us back, that voice of self-doubt.”

“If you get a social invitation, recognize the moment as a decision point,” said Patrice Jenkins, a retirement consultant and author of “What Will I Do All Day?” “Don’t default to say ‘no’ and settle into what’s comfortable.”

You can’t flip a switch and apply the ABCs all at once. Retirement unfolds in stages. But by making strides in integrating agency, belonging and cause into your life, you pave the way for a smooth transition.

New dementia warning sign is hiding in our muscles

 

Make damn sure your competent? doctor has EXACT PROTOCOLS that prevent frailty post stroke! Doesn't have them; fire him/her and replace your incompetent board of directors!

New dementia warning sign is hiding in our muscles

Losing muscle as we age could be an important warning sign for dementia, according to new Curtin University research. Researchers analyzed more than 80 studies examining the links between body weight, body fat, muscle health and dementia, finding people with sarcopenia—the loss of muscle mass and strength—had a 42% higher risk of dementia. Sarcopenia is a condition in which people lose muscle mass, strength and physical function, often as they get older.

The findings, published in the International Journal of Food Sciences and Nutrition, also revealed a surprising difference in how obesity was linked to dementia depending on a person's age. People with obesity in middle age, or before 65, had a 9% higher risk of dementia, while obesity in people 65 and older was linked to a 17% lower risk.

Lead researcher Dr. Uraiporn Booranasuksakul, from Burapha University, said the findings showed that body weight alone did not tell the full story when it came to dementia risk.

"It's not just about how much you weigh—maintaining muscle strength and function also appears to be important as we age," Booranasuksakul said. "Our findings suggest losing muscle could be an important warning sign for dementia risk."

 Booranasuksakul said the findings highlighted the importance of looking after muscle health throughout life. "Maintaining muscle is an important part of healthy aging, and regular physical activity and good nutrition can help support muscle strength and function," she said.

Corresponding author Professor Mario Siervo, from Curtin's School of Population Health, said the findings also challenged the idea that dementia risk could be understood simply by looking at a person's weight.

"We found that obesity in middle age was linked to a higher risk of dementia, but this relationship changed in later life," Siervo said. "This does not mean people should gain weight as they get older. Rather, it shows us that the relationship between body weight, aging and dementia is complex."

The researchers also looked at sarcopenic obesity, in which a person has both low muscle mass or function and excess body fat. Only four studies met the criteria for this part of the analysis, and researchers found no statistically significant link between sarcopenic obesity and dementia.

Siervo said more research was needed to understand whether the combination of muscle loss and excess body fat affected dementia risk.

"There is still a lot we don't know about how changes in muscle and body fat interact over time," Siervo said. "More long-term research is needed to understand whether having both low muscle mass and excess body fat increases dementia risk."

The researchers said the findings reinforced the importance of taking a lifelong approach to maintaining healthy body composition, including preventing unhealthy weight gain during middle age and maintaining muscle strength and function as people get older.

Professor Warren Harding AM, chairman and head of research and partnerships at Alzheimer's WA, welcomed the findings and congratulated Curtin on its investment in dementia research.

"Dementia is a $2.8 trillion global challenge, and the findings from the World Health Organization and the Lancet Commission on the 14 lifestyle risk factors are powerful reminders of the importance of early detection and good eating, exercise, weight, hearing, vision and brain training," Harding said. "The Curtin findings around muscle mass and strength also reinforce the importance of exercise and underline the importance of good mobility and stability to reduce falls as people age."

The study was led by researchers from Curtin University's School of Population Health and Dementia Center of Excellence, in collaboration with researchers from Australia, the U.K., Canada, Thailand and Italy.

Core Contractions Drive Brain Blood Flow

 Does your competent? doctor have enough brains to see this need and provide cerebral blood flow protocols? OH NO, your doctor has been INCOMPETENT FOR OVER A DECADE!

Core Contractions Drive Brain Blood Flow

Summary:

Contracting core abdominal muscles through everyday activities like exercise, walking, or coughing directly regulates blood flow within the brain by causing ultrafast constrictions in major cerebral veins. The findings reveal that cerebral circulation is directly coupled to peripheral mechanical forces, offering fresh clues into the neurovascular benefits of exercise and the mechanics behind movement-triggered migraines.

Key Facts:

  • Ultrafast Venous Constriction: In response to abdominal muscle activation, major cerebral veins, including the superior sagittal sinus and bridging veins, constrict in approximately one-tenth of a second, far outpacing the multi-second response time typical of cerebral arteries.
  • Mechanical Spine-to-Brain Signaling: Core contractions elevate pressure in venous structures connected through the spinal column into the skull, momentarily driving blood flow alterations inside the dural membrane.
  • Relevance to Headaches and Exercise: Because dural veins are embedded in pain-sensitive tissue, these movement-induced pressure fluctuations may explain why physical exertion can exacerbate migraines while simultaneously promoting long-term brain vascular health.

Source: Penn State University

Neuroscientists have long viewed cerebral blood flow as a self-contained system regulated locally within the skull. When a specific brain region increases its metabolic activity, nearby arteries and capillaries relax to supply incoming oxygen and nutrients.

However, a study published in the Proceedings of the National Academy of Sciences (PNAS) demonstrates that cerebral circulation is intimately tethered to mechanical forces generated elsewhere in the body. Researchers discovered that activating core abdominal muscles—whether during purposeful locomotion or involuntary actions like coughing, transmits rapid pressure changes upward through the spinal column to dynamically alter venous blood flow in the brain.

“The brain may be protected inside the skull, but it is not isolated from the mechanical forces generated by the rest of the body,” explained lead author Qingguang Zhang, Ph.D., an assistant professor of physiology at Michigan State University who began the project while at Penn State. “We were surprised by how rapidly and consistently the veins responded to movement… Our findings show that mechanical signals generated by the body can have immediate consequences for the circulation inside the skull.”

Beyond “Passive Pipes”: Veins as Active Regulators

Blood flow throughout the body requires continuous redistribution depending on dynamic organ demands. Senior author Patrick Drew, Ph.D., professor of biology, engineering science and mechanics, neurosurgery, and biomedical engineering at Penn State, compares this coordination to a municipal utility.

“A city’s water system has to be able to accommodate different use needs of an apartment building or a single-family home, or even a full stadium on gameday,” Drew said. “Blood flow in the body must be precisely controlled because different organs need different amounts of blood at different times.”

Historically, arteries and capillaries have taken center stage in neurovascular studies because they are encircled by smooth muscle cells that dilate and constrict in response to local chemical signals. Cerebral veins, possessing far less musculature, have often been viewed as passive drainage channels.

The new findings challenge that assumption. By monitoring vascular dynamics during natural mouse movement, the researchers observed rapid, marked constrictions of the superior sagittal sinus, the primary vein running along the superior midline of the brain, and its feeding bridging veins. While arterial contractions generally unfold over several seconds, these cerebral veins reacted within roughly 100 milliseconds of core abdominal engagement.

“Veins are not simply passive pipes,” noted Zhang. “When we think about brain blood flow regulation, we tend to focus heavily on arteries. Our results highlight the other side of circulation. What happens to blood as it leaves the brain can be just as dynamic and physiologically important.”

Implications for Exercise, CSF Flow, and Migraine Pain

The physical mechanism originates in the abdomen. Engaging the abdominal wall increases pressure across the vascular networks that link the torso to the cranial vault via the spinal column. This mechanical surge creates an instantaneous narrowing of cerebral outflow channels, momentarily boosting blood flow.

In previous research, the team showed that abdominal contractions also physically displace the brain by tiny increments, helping to circulate protective cerebrospinal fluid (CSF). Because mouse and human vascular architectures share close physiological homology, the investigators expect this core-to-brain hemodynamic coupling to operate similarly in humans.

The findings may clarify several clinical enigmas:

  • The Exercise-Brain Connection: Regular physical activity provides proven cognitive and neuroprotective benefits. The continuous pumping and constriction of dural veins during physical exertion could be a driving force behind improved clearance and circulation.
  • Headaches and Migraines: Unlike brain tissue itself, the surrounding protective dura mater is dense with sensory pain receptors. Rapid pressure spikes and venous shifts within dural veins could explain why movements like bending over, coughing, or exercising often trigger or intensify migraine pain.

By mapping the mechanical pathways linking core movement to the cerebral vasculature, the researchers aim to lay the groundwork for better identifying neurovascular dysfunctions and designing future interventions.

The pan-immune-inflammation value predicts stroke-associated pneumonia and poor outcome in spontaneous intracerebral hemorrhage: a machine learning approach


  • Department of Neurology, Longyan First Affiliated Hospital of Fujian Medical University, Longyan, Fujian, China

Abstract


Objective: 


Stroke-associated pneumonia (SAP) constitutes a major complication following spontaneous intracerebral hemorrhage (sICH), posing a significant clinical challenge for accurate prediction. This study aimed to evaluate whether integrating the pan-immune-inflammation value (PIV) enhances the predictive performance of machine learning (ML) models for SAP and poor functional outcome.


Methods: 


A retrospective cohort of 371 sICH patients was analyzed. Feature selection was performed using the least absolute shrinkage and selection operator (LASSO). Predictive models for SAP and poor outcome [modified Rankin Scale score (mRS) > 2 at 90 days] were developed and compared across nine ML algorithms. Model performance was assessed by discrimination (area under the receiver operating characteristic curve, AUC), calibration, and decision curve analysis (DCA). Interpretability was achieved via SHapley Additive exPlanations (SHAP).


Results: 


Elevated PIV was independently associated with SAP [odds ratio (OR) 13.55, 95% confidence interval (CI) 4.14–44.39; p < 0.0001] and poor 90-day functional outcome (OR 25.27, 95% CI 7.75–82.34; p < 0.0001). Among the algorithms, extreme Gradient Boosting (XGBoost) and logistic regression (LR) demonstrated the highest predictive performance for poor outcome (AUC 0.912) and SAP (AUC 0.856), respectively. Incorporating PIV significantly improved discriminatory ability (XGBoost: 0.926–0.942; LR: 0.905–0.931; both p < 0.05). The models demonstrated good calibration, provided net clinical benefit on DCA, and were interpretable through SHAP analysis, which consistently identified PIV as a critical predictor.


Interpretation: 


The integration of PIV into interpretable ML models significantly improves the accuracy of predicting SAP and functional outcome after sICH. This strategy, combining a systemic inflammatory biomarker with explainable ML, holds promise for advancing personalized risk stratification in neurocritical care.

Abstract


Background and objective: 


Early neurological deterioration (END) is a critical clinical event associated with poor patient outcomes after acute ischemic stroke. Early identification of high-risk patients is crucial for timely clinical management. This study aimed to develop and validate a model for predicting END risk for acute ischemic stroke patients using machine learning algorithms.


Methods: 


This study retrospectively and consecutively enrolled 1,151 patients with acute ischemic stroke from the Stroke Center of Beijing Shunyi District Hospital between January 2021 and December 2024. END was defined as progressive worsening of neurological deficit symptoms after onset. Predictive variables were screened using univariate analysis and multiple feature selection methods (Treebag, Boruta, Bayesian). Nine machine learning algorithms (Decision Tree, Efficient Neural Network, K-Nearest Neighbors, Light Gradient Boosting Machine, Logistic Regression, Multilayer Perceptron, Random Forest, Simplified Support Vector Machine, Extreme Gradient Boosting) were employed to construct prediction models. Hyperparameters were optimized via 10-fold cross-validation, and model performance was evaluated in an internal validation cohort (30% of the sample). Primary evaluation metrics included the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, accuracy, F1 score, and net benefit from decision curve analysis (DCA). The SHAP method was used to interpret the optimal model.


Results: 


A total of 161 patients (14.0%) developed END. Feature selection ultimately identified five key predictors: ischemic stroke etiological subtype, Oxford Community Stroke Project (OCSP) classification, age, atrial fibrillation history, and prior stroke history. In both the development and internal validation cohorts, the logistic regression model demonstrated favorable and stable performance (development cohort AUC: 0.787, 95% CI: 0.735–0.839; internal validation cohort AUC: 0.751, 95% CI: 0.668–0.834), with a low log-loss value. DCA suggested potential clinical utility of the logistic regression model. SHAP analysis revealed that the etiological subtype of ischemic stroke and age were the features contributing most to the model’s predictions.


Conclusion: 

This study successfully developed and validated a logistic regression model for predicting END risk. The model incorporates five routinely available clinical variables and demonstrates satisfactory predictive performance and interpretability. The developed online tool may assist clinicians in early risk stratification, providing a reference for personalized intervention.

Association between lactate-to-albumin ratio and in-hospital mortality in ICU patients with acute ischemic stroke: a retrospective cohort study

 And you think predicting mortality is more important than research to prevent mortality? YOU'RE FIRED!

Association between lactate-to-albumin ratio and in-hospital mortality in ICU patients with acute ischemic stroke: a retrospective cohort study


  • West China Hospital, Sichuan University, Chengdu, Sichuan, China

Abstract


Background: 


Early risk stratification is critical for critically ill patients with ischemic stroke. The prognostic value of the lactate-to-albumin ratio (LAR) remains unclear in this population.


Methods: 


This single-center retrospective cohort study enrolled adult ICU patients with ischemic stroke from West China Hospital. LAR was calculated using the first lactate and albumin values on ICU admission. Log-transformed LAR was adopted as the main exposure, and the primary outcome was in-hospital mortality. Multivariable logistic regression, ROC analysis, quartile stratification, subgroup, and sensitivity analyses were performed among 749 patients with complete exposure and outcome data, of whom 576 had complete covariate data and comprised the primary multivariable regression cohort.


Results: 


A total of 749 patients were included, with an in-hospital mortality rate of 30.7%. In complete-case multivariable analysis (N = 576; deaths = 172), log-transformed LAR was independently associated with in-hospital mortality (OR = 1.44, 95%CI: 1.09–1.91, p = 0.010) after full adjustment. Each two-fold increase in LAR was associated with a 29% increase in mortality odds. The highest LAR quartile had a significantly higher mortality risk than the lowest quartile (OR = 2.16, 95%CI: 1.21–3.92). LAR showed modest predictive ability (AUC = 0.628). When modeled as a raw continuous LAR, the direction of association remained consistent but did not reach conventional statistical significance (OR 1.23; 95% CI 0.97–1.56; p = 0.083). Moreover, no significant interaction or non-linearity was found.


Conclusion: 


Elevated LAR is independently linked to higher in-hospital mortality among critically ill ischemic stroke patients. It may serve as a simple adjunctive marker for early risk stratification.
