Hi,
Thank you for posting your query.
I have noted your father's diagnosis and current symptoms.
Memory and language problems may occur in people with Parkinson's disease (PD), especially after several years of suffering.
It is good news that CT can of brain is normal, as it excludes other problems such as brain
stroke, tumours, etc.
Medicines used for treating PD may cause e=adverse effects, so, i would request you to send the medication details, along with the dose and timings.
It would be also worthwhile discussing the medications with his
neurologist.
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)
