hi, thank you for providing a brief history of your son. as mentioned your son had cerebral hemorrhage and he visited the hospital only after 3 days. well there might be a chance where the cerbreal angiography must have not revealed much in the diagnostic test. an MRI contrast would have played a role as well to help come closer to the issue. also there is nothing called glue as per my knowledge which can be performed if something is there I do not know. so can t comment much on it. but ya, if there are symptoms then you should meet a neurologist and get that treated symptomatically with medicine. also you can discuss about undergoing the physical therapy as it will help your son . doing exercise may sound a small thing but the exercise has much more benefits which allows the body to heal on the natural pathway. medicines act as supportive therapy but the natural medicine required for the body can be produced by the body itself for which a good metabolism is needed. you should even keep this into consideration that in future if you find such symptoms infront of you then rush to the ER within the first 3 hours as the first 3 hours plays a crucial role of saving the brain tissue from getting damage. also, physical therapy is of choice is most of the cases of brain hemorrhage. so taking the help of an expert will surely be of the point. also to note that once the 6 months gets over then a re MRI should be performed to check the status of the brain tissue. for more things like to plan the physical therapy and medication you need to discuss in detail with the Neurologist. a close communication between the Neurologist and physical therapist working as a team will be of choice for benefit to make improvement in the status of your son health. with the grace of God I wish your son a healthy life
