Traumatic brain injury occurs when a sudden trauma causes brain damage. TBI can result from a closed head injury or a penetrating head injury. Symptoms of a TBI can be mild, moderate, or severe, depending on the extent of the damage to the brain. Outcome can be anything from complete recovery to permanent disability or death. A coma can also affect a child's brain.
Anxiety and stress can make our memories weaken, and so can physical substances, like drugs and alcohol. Which I'm sure you know, and I'm not lecturing! Be patient with yourself, but if you definitely feel like something isn't right with you, then by all means call your doctor! it can never hurt :)
