Definition: A vivid memory that may include images, sounds, smells, or feelings. With post-traumatic stress disorder (PTSD), these memories are related to the trauma that occurred, and the person having the flashback may feel like he or she is re-living the trauma. With PTSD, flashbacks often are recurring and disturbing. During a flashback, the person may lose touch with reality. Flashbacks sometimes have triggers (such as the anniversary date of the event or particular sounds or smells) but may also occur without a specific trigger, even when the person is relaxed.
For a further understanding of post-traumatic stress disorder or PTSD, please see our PTSD and Trauma resources. To find out whether or not you have the symptoms of PTSD, take the Post-Traumatic Stress Disorder Screening Test.
