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.

Study Finds Link Between Alzheimer's and Herpes

I had two forms of the virus as a kid; chicken pox and cold sores. Should I be taking these antiviral drugs as a precaution?

Study Finds Link Between Alzheimer's and Herpes

A new commentary by scientists at the Universities of Manchester and Edinburgh on a study by Taiwanese epidemiologists supports the viability of a potential way to reduce the risk of Alzheimer’s disease.
When the Taiwanese authors looked at subjects who suffered severe herpes infection and who were treated aggressively with antiviral drugs, the relative risk of dementia was reduced by a factor of 10.
Manchester’s Professor Ruth Itzhaki and Edinburgh’s Professor Richard Lathe say the paper, by Tzeng et al. and published in Neurotherapeutics in February 2018, also shows that herpes simplex virus type 1 (HSV1) leads to an increased risk of developing the disease.
“This article and two others by different research groups in Taiwan provide the first population evidence for a causal link between herpes virus infection and Alzheimer’s disease, a hugely important finding,” said Itzhaki.
They publish a commentary in the Journal of Alzheimer’s Disease on the three articles, arguing that they provide the strongest evidence yet for a causal link between herpes infection and Alzheimer’s disease, backing 30 years of research by Itzhaki.
Itzhaki said: “I believe we are the first to realize the implications of these striking data on this devastating condition which principally affects the elderly. No effective treatments are yet available.
“Almost 30 million people worldwide suffer from it and sadly, this figure will rise as longevity increases.
“But we believe that these safe and easily available antivirals may have a strong part to play in combating the disease in these patients.
“It also raises the future possibility of preventing the disease by vaccination against the virus in infancy.
”Successful treatment by a specific drug, or successful vaccination against the putative microbe, are the only ways to prove that a microbe is the cause of a non- infectious human disease.”
Most Alzheimer’s disease researchers investigate its main characteristics — amyloid plaques and neurofibrillary tangles; however, despite the vast amount of research, the causes of their formation are unknown.
HSV1 infects most humans in youth or later and remains lifelong in the body in dormant form within the peripheral nervous system.
From time to time the virus becomes activated and in some people it then causes visible damage in the form of cold sores.
The Taiwanese study identified 8,362 subjects aged 50 or more during the period January to December 2000 who were newly diagnosed with severe HSV infection.
The study group was compared to a control group of 25,086 people with no evidence of HSV infection.
The authors then monitored the development of dementia in these individuals over a follow-up period of 10 years between 2001 and 2010.
The risk of developing dementia in the HSV group was increased by a factor of 2.542. But, when the authors compared those among the HSV cohort who were treated with antiviral therapy versus those who did not receive it, there was a dramatic tenfold reduction in the later incidence of dementia over 10 years.
“I believe we are the first to realize the implications of these striking data on this devastating condition which principally affects the elderly. No effective treatments are yet available,” said Itzhaki.
Professor Richard Lathe added: “Not only is the magnitude of the antiviral effect remarkable, but also the fact that — despite the relatively brief duration and the timing of treatment — in most patients severely affected by HSV1 it appeared to prevent the long-term damage in brain that results in Alzheimer’s.
Itzhaki said: “It was as long ago as 1991 when we discovered that, in many elderly people infected with HSV1, the virus is present also in the brain, and then in 1997 that it confers a strong risk of Alzheimer’s disease in the brain of people who have a specific genetic factor.
“In 2009, we went on to show that HSV DNA is inside amyloid plaques in Alzheimer’s patients’ brains.
“We suggested that the virus in brain is reactivated by certain events such as stress, immunosuppression, and infection/inflammation elsewhere.
“So we believe the cycle of HSV1 reactivation in the brain eventually causes Alzheimer’s in at least some patients.”
The study by Tzeng et al. investigated only people with severe HSV and cannot be generalized to healthy populations.
The paper, “Herpes Viruses and Senile Dementia: First Population Evidence for a Causal Link,” is published in the Journal of Alzheimer's Disease.
