Trauma trigger
(重定向自Triggering)
A trauma trigger is an experience that causes someone to recall a previous traumatic memory, although the trigger itself need not be frightening or traumatic and can be indirectly or superficially reminiscent an earlier traumatic incident. Trauma triggers are related to posttraumatic stress disorder (PTSD), a condition in which people often cannot control the recurrence of emotional or physical symptoms, or of repressed memory. Triggers can be subtle and difficult to anticipate, and can sometimes exacerbate PTSD. A trauma trigger may also be referred to as a trauma stimulus or a trauma stressor.
