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.

Exercise Can Improve Memory in People Over 60

What exact stroke exercise protocol is your doctor prescribing to prevent your memory problems? ANYTHING AT ALL?
Or are you on your own like everything else in stroke rehab?
http://www.biosciencetechnology.com/news/2014/10/exercise-can-improve-memory-people-over-60?
A new study, in which researchers from Karolinska Institutet participated, shows that physical activity can improve memory performance in older people through increasing volume and blood flow in an area of the brain called hippocampus. It is the first time these connections are being studied in people over 60 years of age. The results are published in the journal Molecular Psychiatry.
The hippocampus is a brain structure located deep in the temporal lobe and is important for memory and learning. Previous research shows that aerobic exercise can, among other things, increase blood flow in hippocampus among younger people. The present study, which was led by a research team from Magdeburg in Germany, is the first that also links these changes to improved memory functioning.
During a three month period, the researchers studied a group of individuals, aged 60 and older, who exercised during a personalized thirty-minute session on a treadmill three times a week. In the comparison group, participants performed stretching and muscle relaxation exercises. In both groups, measurements were taken of episodic memory (memory for personal experiences), volume and blood flow in hippocampus, and participants' physical fitness as measured by maximal oxygen uptake.
“We could then see that participants' fitness level had improved, which was related to changes in memory, hippocampal volume, and blood flow in hippocampus,” said Lars Bäckman, professor of cognitive neuroscience at Karolinska Institutet and affiliated to the Aging Research Center in Stockholm.
Increased blood flow
The researchers tested various models to explore the relationships among the findings. It was revealed that the increase in hippocampal volume in those participants who underwent the exercise program can largely be explained by increased blood flow. According to the researchers, it is probably due to an increase in vascular plasticity, i.e., the ability to expand and form new blood vessels, rather than to the formation of more neurons in hippocampus after physical activity.
“Thus, one point is that it may be the increase in blood volume and oxygenation that underlies improved memory, rather than an increase in the size of hippocampus itself,” said Martin Lövdén, professor in the cognitive neuroscience of aging at Karolinska Institutet and also working at the Aging Research Center.
Younger elderly persons
The findings in this study apply to persons between 60 and 70 years, thus younger elderly persons. Among participants over 70, the same effects of the exercise were not observed, which suggests there may be an age limit for this type of plasticity in the brain. The team will now continue with its work and study if it is possible to combine physical exercise with cognitive training in order to achieve even higher plasticity among older persons.
