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.

Compound repairs features of Alzheimer’s disease in mice

You'll want your doctor to follow this research because of your likely Alzheimer and Parkinsons risks.

Your chances of getting dementia.

1. A documented 33% dementia chance post-stroke from an Australian study?   May 2012.
2. Then this study came out and seems to have a range from 17-66%. December 2013.
3. A 20% chance in this research.   July 2013.
 

Your Parkinsons risk:

Parkinson’s Disease May Have Link to Stroke

At a Glance

  • Researchers found that a compound called an NAD+ precursor helped mice with features of Alzheimer’s disease perform better on learning and memory tests.
  • The findings pave the way for studies of the compound’s potential as an intervention for people with Alzheimer’s disease.

Alzheimer’s disease is a brain disorder that slowly destroys thinking, memory, and language skills. It’s the most common cause of dementia among older people. Experts estimate that more than 5 million Americans are living with the disease. Symptoms usually begin after age 60. There is no cure.
The brain’s usual DNA repair activity is impaired in Alzheimer’s disease, leading to inflammation and dysfunction. A compound that the brain needs to regulate DNA repair and other key signaling pathways is known as nicotinamide adenine dinucleotide (NAD+). Because NAD+ declines with age, scientists have wondered whether boosting the level of NAD+ could help aging brain cells (neurons) to function better. One way to increase the cellular level is by giving an NAD+ precursor compound, such as nicotinamide riboside (NR). NR is a form of vitamin B3.
An international research team led by Dr. Vilhelm A. Bohr at NIH’s National Institute on Aging (NIA) set out to test whether NR supplements could normalize NAD+ levels in the brains of mice and counteract deficits in thinking and memory. The study was published online on February 5, 2018, in the Proceedings of the National Academy of Sciences.
The research team used findings from their previous studies with human cadaver brain tissue to develop a new strain of mice. These mice had the main features of human Alzheimer’s disease, such as the abnormal buildup of the proteins tau and amyloid-beta. The research team added the NR supplement to the mice’s drinking water for three months.
The team found that the NR-treated mice had less DNA damage, lower levels of neuron damage and death, increased production of new neurons, and lower brain inflammation than control mice. Mice who received NR had reduced tau in their brains, too, but amyloid-beta levels were unchanged. The NR-treated mice performed better than control mice on many learning and memory tests, such as a water maze. In addition, NR-treated mice had better muscle strength and endurance than controls.
The research team also tested human cells from people with and without Alzheimer’s disease. As in the mouse studies, NR decreased DNA damage in the cells from people with Alzheimer’s.
“The pursuit of interventions to prevent or delay Alzheimer’s and related dementias is an important national priority,” says NIA Director Dr. Richard J. Hodes. “We are encouraging the testing of a variety of new approaches, and this study’s positive results suggest one avenue to pursue further.”
“We are encouraged by these findings that see an effect in this Alzheimer’s disease model,” Bohr says. “We are looking forward to further testing of how NR or similar compounds might be pursued for their possible therapeutic benefit for people with dementia.”
The team is continuing to study the biological mechanisms of Alzheimer’s disease in preparation for possible studies of the approach in people.
