Areteriosclerosis

Hi.
My mom is 80 years old. She was diagnosed with arteriosclerosis (calcium deposits in the brain vessels). Everything else is normal such as blood pressure, heart arteries, Sugar level, etc). She goes to a geriatric dept for maintenance every half a year. After it she feels good for about a week or two then all the symptoms come back. The symptoms are: bad brain fog and vertigo. She is afraid even to step out of the house. I was surprised that doctors did not prescribe vitamins.

Could you suggest vitamins, herbs, minerals for such condition?

Thanks,

Klauss.
