My father is 62 and is suffering from dizziness, occasional nausea and vomiting from past 10-12 days. Little dizziness is felt almost daily.. Sometimes it is more. BP and
sugar is normal. Brain MRI shows small old lacunar infarct and mild cerebral atrophy but no evidence of acute infarct, bleed or sol. Had visited doctor a week back and he is under medication. But still he is not feeling well. Not sure of exact cause and diagnosis. Please suggest what could be the cause and further course of action. Thanks in advance.
