Blunt Head Trauma

Approximately four months, I managed to go and hit my head into a concrete curb. Since that day, my mental faculties were granted the poorest and the poorest. I used to be an A / B student, now his main and D's F. My logical capacities have been worse, my problem solving ability and attention turned to hell, and I was starting to have suicidal thoughts and indiscriminate killings. I want a clear answer: Blunt Force head injury can cause any change in mental status?

A blunt trauma or other trauma to the head can cause a change in your mental state. Mental retardation is not included. You should talk to a doctor immediately, there may be something wrong with your brain that is causing your problems. Also talk about the thoughts of suicide and homicide to someone, preferably a doctor or therapist.

Whatever you do, seek help immediately. Before you do something you regret it.

Yes.
Go see a doctor, tell him everything you've written here. There may be treatments (I'm sure there).

I totally agree with the post above me.

Yes it can cause a huge change in your brain! I would like to see a neurologist or something as soon as possible. You probably have really bad damage to your brain. See the link for more info. I think it's related.
