A 23-year-old female asked:

Can a concussion trigger acute psychosis and/or lead to chronic psychosis?

Yes: Head injury leading to concussion may cause structural damage to the brain. Such damage could affect normal funtion and the cellular levl inthe brain , leading to psychosis.

Concussion Psychosis: No. The symptoms of post traumatic injury can appear to be like a psychosis but only for a short period of time. Brain injury does not cause psychosis. I have seen psychosis diagnosed in people after head injury but this was just that the psychosis had been unmasked by the injury. It existed before the injury.
Dr. Robert Olsen

There is some debate: I agree with dr. Bessinger that under most circumstances the answer is no. However, if the circumstances or situation of the injury are sufficiently grave, there may be the possibility of ptsd with psychosis. This debate will be answered as we watch the course of recovery of our concussed traumatized troops from iraq and afghanistan.
