Hi there and thanks so much for your question.
Those hemorrhages are really tricky and although the doctor maybe has given you a conservative approach sometimes recovery goes faster thanks to the neuroplasticity of the brain. I know how frustrating must be for you but he needs all your help and support and like the doctor say he will slowly recover. As long as he can he should do exercises regarding motor control, sensory processing integration, balance, coordination. Not sure if he is affected in motor functions hopefully not.
I hope this helps and you can post the same question at "neurology" or similar forums.
I really hope I was useful and your friend can recover fast
thank's for your help.it means a lott :)
