Traumatic Brain Injury

I had a sub-dural hematoma in the frontal lobe of my brain about 15 years ago.  It happened when I was about 12 years old.  Soon after this, I began to have bizarre outburst of rage...I would wake up on the floor with someone holding me down and not remember why.  My parents contributed the change in behavior as an hormonal thing.  However, I am now 26 and still have uncontrollable outbursts of anger and also bizarre sexual urges.  Could this still be due to my head injury...should I see a specialist.  My life has been spiraling downward since that injury.
