Hi, Thank you for posting your query. I have noted your father s symptoms and diagnosis. Ischemic stroke leads to partial damage to brain nerves, if not treated on time. The only treatment that can salvage most of brain tissue is thrombolysis with tissue plasminogen activator. Based on your description, he seems to not have received thrombolytic therapy. In this case, we do not expect complete recovery of his speech and right sided weakness. If you can upload his MRI brain report, we would be able to assess the damage to the left side of his brain, that controls the speech and right hand strength. I hope my reply has helped you. I would be pleased to answer, if you have any follow up queries or if you require any further information. Best wishes, Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology) Senior Consultant Neurologist Apollo Hospitals, Hyderabad, For DIRECT QUERY to me: http://bit.ly/Dr-Sudhir-kumar My blog: http://bestneurodoctor.blogspot.com/
