Hello Cira, Thanks for posting on HCM From your description, I can tell that your friends problem has become very complicated and might not have any definitive treatment as from the look of things there is probably permanent nerve damage in the brain and additional psychological disorder. He would require the attention of a neurosurgeon + a neuropsychiatrist in order to be able to handle his problem. There would have to run a series of exams such as MRI, brain CT scan, EEG and even PET scan just to be able to determine the cause of his problem and also see if it can be surgically or medically corrected. From the look of things he did not receive proper treatment immediately after the accident and so, the injury caused in his head, probably has become irreversible. If you have the means, then you can start his follow up and later on management. Wish you and your friend the best
