Trauma and PTSD: Understanding the Brain in the Midst of Recovery

Abstract

Post-traumatic stress disorder (PTSD) should be considered in anyone exposed to a traumatic event [1]. Approximately 60% of men and 50% of women will experience trauma at some point in their life. Nonetheless, trauma exposure does not guarantee the onset of PTSD symptoms; typically, only 4% of men and 10% of women end up developing PTSD after experiencing trauma [2]. The psychological mechanisms in which PTSD is prevented within an individual is not well understood. Thus, recognition of the onset of symptoms and comprehension of the neurobiology of this disorder are critical for diagnosis, treatment and recovery [1].
