Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 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:

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's quite disgusting that this information is not available from every stroke association and doctors group.

Exercise Results in Larger Brain Size, Lowered Dementia Risk

A totally worthless writeup. No mention of the definition of low exercise so individuals could actually use this information. A great stroke association president would be reaming these people out for not providing anything useful.

Using the landmark Framingham Heart Study to assess how physical activity affects the size of the brain and a person’s risk for developing dementia, researchers found an association between low physical activity and a higher risk for dementia in older individuals.
The findings, published in the Journals of Gerontology Series A: Biological Sciences and Medical Sciences, suggest that regular physical activity for older adults could lead to higher brain volumes and a reduced risk for developing dementia.
Zaldy Tan, MD, University of California, Los Angeles (UCLA), Los Angeles, California, and colleagues found that physical activity particularly affected the size of the hippocampus.
In addition, the protective effect of regular physical activity against dementia was strongest in people aged 75 years and older.
Though some previous studies have found an inverse relationship between levels of physical activity and cognitive decline, dementia and Alzheimer’s disease, others have failed to find such an association.
The Framingham study was begun in 1948 primarily as a way to trace factors and characteristics leading to cardiovascular disease, but also examining dementia and other physiological conditions.
For the current study, the UCLA researchers followed an older, community-based cohort from the Framingham study for more than a decade to examine the association between physical activity and the risk for incident dementia and subclinical brain magnetic resonance imaging (MRI) markers of dementia.
The researchers assessed the physical activity indices for both the original Framingham cohort and their offspring who were aged 60 years and older. They examined the association between physical activity and risk of any form of dementia (regardless of the cause) and Alzheimer’s disease for 3,700 participants from both cohorts who were cognitively intact. They also examined the association between physical activity and brain MRI in about 2,000 participants from the offspring cohort.
Over a decade of follow-up, 236 participants developed dementia (188 Alzheimer’s dementia). Participants with the lowest levels of physical activity had an increased risk of incident dementia compared with those with higher levels of physical activity. Physical activity also related to total brain and hippocampal volumes.
