  1. 1. PTSD By, Lucas Millman and Adam Hall
  2. 2. About PTSD • PTSD stands for Post Traumatic Stress Disorder • It is a psychiatric illness that affects the brain after it goes through a traumatic experience • It was first identified in veterans from Vietnam who had a traumatic experience • The types of traumatic events range from losing a loved one, experiences in prison, assault, domestic abuse, rape, war experiences • It can happen to any age, race or gender and does not always occur right after the traumatic event
  3. 3. Study in Rwandan Genocide • A study identified genes as potential biologic markers linked to PTSD • Scientist screened surviving victims of the Rwandan genocide where the total death toll was about 500,000 people • Rwandans experienced significant trauma by witnessing traumatic events or losing loved one • The study evaluated blood samples and reviewed medical records from 424 Rwanda genocide survivor, participants experienced trauma but one group was diagnosed with PTSD • The study found a "dose-response" relationship between traumatic load and the widespread appearance of lifetime PTSD • Their hypothesis suggests a direct relationship where the higher amount of traumatic load, the more likely the chance of developing PTSD • Scientists also found genetic biomarkers directly linked to the "traumatic load"
  4. 4. COMT • The COMT stands for catechol-O-methyltransferase • It is an enzyme produced by all individuals with some variability • COMT "digests" the chemicals produced when stress occurs • COMT used to be linked with the feeling of fear • They concluded people with less COMT have a higher stress load leaving them more vulnerable to PTSD • This study may provide information putting us one step closer to finding a biologic intervention for prevention or treatment of mental disorders related to stress like PTSD
