Can Concussion Cause Anxiety And Panic Disorder?

I am trying to inquire about several things: As a child, 8-9 years of age...I was in a car accident.. the car turning end over end 5 times.We were pushed off the road. I received a concussion and was kept out of school to recover. I remember headaches, and a lump on my forehead that felt like oil having been set on fire where the concussion was I was wondering if I could have some damage that showed up in later years. ( I am 69). I have had several knots on my head my bumping into open cabinets during the years with some large knots resulting and lasting a few days.... At one point I had severe headaches and had a brain scan done. All I remember from that was a horn on one side was larger than the other. .aybe a sign of pkssible epilepsy. I have never had an epileptic attack so that doesn t concern me too much. The other finding was in the bottom of the acm of my bead where two ( glands.l hang a litte lower on o e side. ( Possible chia 1?) I have djscovered a dent above my left temple and a bit back from my forehead. I was wonderi g if that could e the deason I have some personality disorder.... ocd and obsessive compulsive problems. My biological mother had anxiety panic attacks.. so I feel some of my problem is ge etic. My question is: could that concussion cause me to bave personality disorder, ad krva izational skills, difficulty with math, ocd, and some of the mental issues I have. Could that be checked? The dent in my head bothers me. Would a scar move to the back of my head as like a scar moves from it s original site as people ave?... I have been doing lots of reading on the brain but haven t found my answer yet... can you help???
