Stroke attack / Mentally unstable.

My Father suffered a stroke. Only after CT Scan results we came to know that this was a second stroke . Injection was administered to break up the clots within 1 hour. Its almost 2 months now he is still very agitated/restless and always has a tendency to go out. We had taken him to the place of his choice for past 2-3 weeks but it seems that we are only going from place to place and efforts going in vain. He does remember all of our relatives, the way to their houses and some of his passwords. His speech is not proper and has ran away from house couple of times when we restricted. We have to keep all doors locked at all times so he is yelling on top of his voice. Doctor suggested to give qutan 50 morning and evening, earlier it was qutan 100 at night. The situation still remains the same only that the period he is sedated he is less agitated. Kindly advice. Find attached reports.
