Concussion: A concussion is a traumatic brain injury that alters the way your brain functions. Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination. http://www.mayoclinic.org/diseases-conditions/concussion/basics/definition/con-20019272

Head trauma: It is clear you have a history of head trauma but your question is not clear. If you have symptoms, be they physical or about memory, etc. please see you doctor. A neuropsychologist can do testing to identify and give strategies to help if you have cognitive issues. Peace and good health.
