	'''Post-traumatic amnesia''' ('''PTA''') is a state of confusion that occurs immediately following a [[traumatic brain injury]] (TBI) in which the injured person is disoriented and unable to remember events that occur after the injury. The person may be unable to state their name, where they are, and what time it is. When continuous memory returns, PTA is considered to have resolved. While PTA lasts, new events cannot be stored in the memory.
