Thank you for posting your query.
First of all, you should stop worrying about the future risk of dementia
. Though Alzheimer's disease (AD) can be familial, this risk is very low, and less than 10% of AD cases are familial.
Poor blood flow to brain can lead to strokes and dementia. So, you should get screened for high BP
, sugars, and cholestol, which are the risk factors for brain strokes. If any of them are abnormal, you should get them treated.
