EPA and DHA supplementation in posttraumatic stress disorder


Posttraumatic stress disorder is a reaction to a traumatic event that can occur in people who have experienced or witnessed a shocking, frightening, or dangerous event (a natural disaster, an accident, a violent personal assault, a sudden death of a loved one, or other life-threatening events). Most people who experience such events recover from them, but people with post-traumatic stress disorder continue to be depressed and anxious for months or even years following the event, which has consequences in their day-to-day life. These people may feel stressed or frightened even when they are not in danger; they often relive the traumatic event through nightmares and flashbacks, and may have feelings of isolation, irritability or guilt, sleep disturbances and concentration difficulties, among others symptoms.

Psychophysiological symptoms (for example, heart palpitations) are prominent features of post-traumatic stress disorder. As we have already explained in other post, omega-3 fatty acids (EPA and DHA) supplementation may be effective for the reduction of these symptoms.
