Hi,I use to have a quick temper.i did have a TBI when i was in viet nam but not sure as ive always been a nervous person Not a violent temper.
I have found ways to avoid issues by recognizing fear and anger in all their faces and avoiding it.Usually is just a little frustration that escalates.the way to strengthen your nervous system is through doing things you fear and hate to do.Like I did some volunteer work i realy didn't want to do .Afterwards u had much better impulse control when I became frustrated.
Doing this can lead to a depression free life which I enjoy pretty much despite my PD and this jerking condition.I found the works from Dr.Abraham Low to be very helpful in this venture for better mental health.

Hi John,
I want to thank you for serving our country. I remember Vietman very well. The hot temper could be do to the area of your brain that was injured
if the frontal lobe (forehead) is the area that controls a persons temper. As far as depression that is all part of having epilepsy and some other neurology problems. It can also come from the meds a person is taking and a person can get depressed as well as have a hot temper.
You went through a lot and having a TBI injury is no fun, I can relate to it since I've had 2 brain surgeries. Try taking vitamin B12 1000 mcg. once a day it works great reducing seizures and it helps calm a persons nerves. I wish you only the best of luck and May God Bless You!
