Can RAS inhibitors reverse or treat vascular dementia?

[Bird_42]

My mother is 80 years old.

Since 2018, she has been seeing her deceased husband (my father), her deceased parents, and her deceased sister in her own home. In other words, she has been having hallucinations.

A CT scan of the head, without contrast, was performed on my mother 3 weeks ago. According to the result of this CT scan, "severe cerebral white matter microvascular ischemic changes" can be seen.

These microvascular ischemic changes and the hallucinations of deceased relatives led my mother's doctors to conclude that my mother probably has vascular dementia.



According to the following websites, microvascular ischemic changes in the brain can be reversed or treated by RAS (renin-angiotensin system) inhibitors:

Does anyone know anything about RAS inhibitors being used to reverse or treat microvascular ischemic changes in the brain or vascular dementia?

What are some examples of medications that are RAS inhibitors? Can RAS inhibitors be obtained at a pharmacy? Or are RAS inhibitors available only in a hospital setting?



Thank you for any information.
