Hi,
Thank you for posting your query.
Your brother needs to be evaluated by a
neurologist. His symptoms are suggestive of
dementia, where the brain functions deteriorate. In addition, we need to exclude brain
stroke (due to lack of blood flow to brain) and seizures (or
fits).
White patches or hyperintense lesions on brain could be suggestive of
ischemia (lack of blood flow to brain).
There are good treatments available for the conditions I listed above.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
