Post-traumatic stress disorder
Extreme psychological trauma sometimes leads to post-traumatic stress disorder (PTSD), a condition in which intrusive memories of the traumatic event recur persistently and cause the individual to experience sustained, severe anxiety. Following exposure to severe stress, the body releases cortisol, a hormone that helps quell the "fight or flight" response to a life-threatening situation. When cortisol is elevated for a prolonged period, as is the case with PTSD, it can harm brain structures that are vital to memory. Damage to the hippocampus has been found in people with PTSD (see "Stress").
The memory problems caused by PTSD can be reversed if effective treatment is started promptly. Treatment typically entails a combination of medication and psychotherapy. However, if cortisol causes damage to the hippocampus and other brain structures, the resulting memory difficulties will be permanent.
