Dear Mr Rajendra Bhole,
Your father's improvement will be gradual and can be helped by continuing the physiotherapy
and exercises which must have been taught in the hospital. It is true that the blood pressure must be kept under good control to prevent a further episode of bleeding. Your doctor is correct that there is no cure once stroke
has happened and we can only prevent it by ensuring that the blood pressure is under control. The are of brain which has already been destroyed will not recover, but physiotherapy and exercises will help the surrounding areas to gradually take over the function. To what extent the improvement occurs will not be certain and it is possible that he may be left with an extent of permanent paralysis
Hope this has clarified some of your questions.
