Hi,
Thank you for posting your query.
I have noted your dad's details including the past medical history and his current symptoms.
It is common for patients to develop
dementia after
coronary bypass surgery. Lack of blood flow to brain is supposed to be a risk factor for dementia.
An MRI brain should be done to confirm the diagnosis. Thyroid profile and
vitamin B12 level should be checked to exclude other causes of his symptoms.
For Alzheimer's disease, good medications include
donepezil,
rivastigmine and memantine.
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)
