After a frightening or overwhelming event, memories may return as images, sounds, nightmares or sudden physical reactions. With post-traumatic stress disorder (PTSD), the past can feel unfinished, as though it repeatedly breaks into the present. Flashbacks may briefly make the event feel real again. [1]
Strong reactions after danger are common, but not everyone develops PTSD. The condition involves patterns such as re-experiencing, avoidance and a persistent sense of current threat that interferes with daily life. Symptoms may become apparent soon after the event or later. [2]
Telling someone to simply forget what happened is rarely helpful. A sensitive clinical assessment focuses on safety, pacing and the person’s preferences. Evidence-based treatments are available, and the person does not need to carry traumatic memories alone. [3]
