Hi Martin. Yes, your head injuries are important, and may be responsible for all or most of your current neurological symptoms. You likely are suffering from a pretty severe post-concussive syndrome. Chances of an aneurysm are low, so don't worry about that. But do see the neurologist (he might want to get an MRI of the brain) and ask for a referral to a physical medicine and rehab specialist (also called a "physiatrist.") as they are the doctors specially trained in diagnosing and treating the consequences of traumatic brain injuries.
