Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 31,940 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke. DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Changing stroke rehab and research worldwide now.Time is Brain!trillions and trillions of neuronsthatDIEeach day because there areNOeffective 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.

Pfizer knew drug may prevent Alzheimer's. Why didn't it tell us?
Because acknowledging it would have resulted in vast pressure to do the trial. It is much cheaper to not release the report. The company doesn't care about anyone's health, profit is the only concern.
A
team of researchers inside Pfizer made a startling find in 2015: The
company's blockbuster rheumatoid arthritis therapy Enbrel, a powerful
anti-inflammatory drug, appeared to reduce the risk of Alzheimer's
disease by 64 per cent.
The results were from an analysis of
hundreds of thousands of insurance claims. Verifying that the drug would
actually have that effect in people would require a costly clinical
trial - and after several years of internal discussion, Pfizer opted
against further investigation and chose not to make the data public, the
company confirmed.
Alzheimer's cause plaques between nerve cells in the brain.
Researchers
in the company's division of inflammation and immunology urged Pfizer
to conduct a clinical trial on thousands of patients, which they
estimated would cost $US80 million, to see if the signal contained in
the data was real, according to an internal company document obtained by
The Washington Post.
"Enbrel could potentially safely
prevent, treat and slow progression of Alzheimer's disease,'' said the
document, a PowerPoint slide show prepared for review by an internal
Pfizer committee in February 2018.
The
company said it decided during its three years of internal reviews that
Enbrel did not show promise for Alzheimer's prevention because the drug
does not directly reach brain tissue. It deemed the likelihood of a
successful clinical trial to be low. A synopsis of its statistical
findings prepared for outside publication, it says, did not meet its
"rigorous scientific standards".
Science was the sole determining factor against moving forward, company spokesman Ed Harnaga said.
Pfizer
said it opted against publication of its data because of its doubts
about the results. It said publishing the information might have led
outside scientists down an invalid pathway.
Pfizer's
deliberations, which previously have not been disclosed, offer a rare
window into the frustrating search for Alzheimer's treatments inside one
of the world's largest drug companies. Despite billions spent on
research, Alzheimer's remains a stubbornly prevalent disease with no
effective prevention or treatment.
Some
outside scientists disagree with Pfizer's assessment that studying
Enbrel's potential in Alzheimer's prevention is a scientific dead end.
Rather, they say, it could hold important clues to combating the disease
and slowing cognitive decline in its earliest stages.
Pfizer did
share the data privately with at least one prominent scientist, but
outside researchers believe Pfizer also should at least have published
its data, making the findings broadly available to researchers.
"Of
course they should. Why not?'' said Rudolph Tanzi, a leading
Alzheimer's researcher and professor at Harvard Medical School and
Massachusetts General Hospital.
"It would benefit the scientific
community to have that data out there,'' said Keenan Walker, an
assistant professor of medicine at Johns Hopkins who is studying how
inflammation contributes to Alzheimer's. "Whether it was positive data
or negative data, it gives us more information to make better informed
decisions.''
Internal
discussions about possible new uses of drugs are common in
pharmaceutical companies. In this case, Pfizer's deliberations show how
decisions made by industry executives - who are ultimately accountable
to shareholders - can have an impact well beyond corporate board rooms.
As
its Enbrel deliberations ended early last year, Pfizer was getting out
of Alzheimer's research. It announced in January 2018 that it would be
shutting down its neurology division, where Alzheimer's treatments were
explored, and laying off 300 employees.

Drug
companies often are criticised for extending the patent life of a drug -
and winning new profits - by merely tweaking a drug's molecule or
changing the method of delivery into the body. But it is a "heavy lift''
for a company to win regulatory approval to use a drug for a completely
different disease, said Robert Field, a professor of law and health
care management at Drexel University.
"Our patent laws do not
provide the appropriate incentives,'' Field said. Drug therapy for early
Alzheimer's "would be a godsend for American patients, so we should be
doing everything we can as a country to encourage development of
treatments. It's frustrating that there may be a missed opportunity.''
As
Enbrel's life cycle winds down, Pfizer has introduced a new rheumatoid
arthritis drug, Xeljanz, that works differently from Enbrel. Pfizer is
putting its marketing muscle behind the new treatment. While Enbrel
revenue is shrinking, Xeljanz revenue is growing. The Xeljanz patent
expires in 2025 in the United States and 2028 in Europe, according to
Pfizer's public disclosures. The drug is on track to make Pfizer
billions more each year for the foreseeable future.
Drug companies
frequently have been pilloried for not fully disclosing negative side
effects of their drugs. What happens when the opposite is the case? What
obligation does a company have to spread potentially beneficial
information about a drug, especially when the benefits in question could
improve the outlook for treating Alzheimer's, a disease that afflicts
at least 500,000 new US patients per year?
A
medical ethics expert argued that Pfizer has a responsibility to
publicise positive findings, although it is not as strong as an
imperative to disclose negative findings.
"Having acquired the
knowledge, refusing to disclose it to those who might act upon it hides a
potential benefit, and thereby wrongs and probably harms those at risk
of developing Alzheimer's by impeding research,'' said Bobbie Farsides,
professor of clinical and biomedical ethics at Brighton and Sussex
Medical School in London.
