Many traumatic events (e.g., car accidents, natural disasters, etc.) are of time-limited duration. However, in some cases people experience chronic trauma that continues or is repeated over months or years, sometimes commencing in childhood. While the current PTSD diagnosis is a very good fit in describing the symptoms suffered by someone who has experienced a discrete or short-lived traumatic event, it does not fully capture the severe psychological harm that occurs with prolonged, repeated trauma.
