Deans' stroke musings: Lower Frequency of Social Contact Linked to Lower Total Brain Volume

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.

Lower Frequency of Social Contact Linked to Lower Total Brain Volume

You don't want less brain volume so make sure your doctor has 100% recovery protocols so you don't immediately lose the first two sets of friends as described by Aristotle.

Well, the solution to this is 100% recovery before you lose the first two groups of friends as described by Aristotle. Your doctor's responsibility.

Aristotle believes that there are three different kinds of friendship; that of utility, friendship of pleasure, and virtuous friendship.

Lower Frequency of Social Contact Linked to Lower Total Brain Volume

An increase in white matter lesions volume has also been seen.

HealthDay News — For older adults, lower frequency of social contact is associated with lower total and cognitive function-related regional brain volumes, according to a study published online July 12 in Neurology.

Naoki Hirabayashi, M.D., Ph.D., from Kyushu University in Fukuoka, Japan, and colleagues examined the association between low frequency of social contact and volumes of various brain regions and assessed the extent to which depressive symptoms mediate these associations in a population-based study involving dementia-free community-dwelling Japanese adults aged ≥65 years. A total of 8,896 participants underwent brain magnetic resonance imaging scans and comprehensive health assessments.

Researchers found that the multivariable-adjusted mean of the total brain volume was significantly lower in the group with the lowest vs the highest frequency of social contact (67.3 vs 67.8%), with a significant increasing trend across the groups. A significant increase was also seen in white matter lesions volume with lower frequency of social contact (0.30 vs 0.26% for lowest vs highest frequency groups). Smaller volumes were seen in the temporal lobe, occipital lobe, cingulum, hippocampus, and amygdala in association with lower frequency of social contact. Depressive symptoms partially mediated the relationships, accounting for 15 to 29% of the observed associations.

“Social isolation is a growing problem for older adults,” a coauthor said in a statement. “These results suggest that providing support for people to help them start and maintain their connections to others may be beneficial for preventing brain atrophy and the development of dementia.”
