Hi,
Thank you for posting your query.
It is unfortunate that your father has suffered a massive brain
stroke of the left side of brain.
This has resulted in right sided weakness and inability to speak/understand.
The recovery is going to be delayed and incomplete. Regular
physiotherapy and
speech therapy would be very useful in ensuring good recovery.
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)
