I was 60 when I had a stroke.

The MRI showed microvascular ischemia "consistent with age". I had enough to worry about, so I didn't really give it much attention.

In the ensuing five years, I've had my share of "senior moments", but I seem to be okay.

I still have plenty to keep me occupied health-wise.

There's some helpful information here:
https://my.clevelandclinic.org/health/diseases/22927-microvascular-ischemic-disease
From that page:
There aren’t specific treatments for microvascular ischemic disease. Currently, treatment focuses on reducing risk factors and staving off complications, such as dementia and stroke.

Every person will have different risk factors, so treatment is highly personalized. In general, treatment may include:

Adopting healthy habits, such as exercising and eating more nutrients.
Quitting smoking.
Taking medications to lower high blood pressure and regulate cholesterol and glucose levels.

I hope this helps.
