4. R ELEVANT STUDY The case of Rwanda Study of PTSD was done on survivors of the Rwandan genocide. The study was done soon after the genocide had occurred. A survey was conducted by UNICEF which looked at 3000 Rwandan children aged 8-19 years They showed: 95% had witnessed violence 80% had suffered a death in their immediate family 62% had been threatened with death According to UNICEF: 60% didn’t care if they grew up Many were parentless and stilled lived in the place where the trauma occurred This left many with repeating flashbacks and constant trauma of the genocide

5. S TRESSOR The person has been exposed to a traumatic event in which both of the following have been present:  The person has experienced, witnessed, or been confronted with an event that involve actual or threatened death or serious injury, or a threat to the physical integrity of oneself or others.  The person’s response involved intense fear, helplessness, or horror.

7. A VOIDANT /N UMBING Persistent avoidance of stimuli associated with the trauma and numbing of general responsiveness (not present before the trauma), as indicated by at least three of the following:  Efforts to avoid thoughts, feelings, or conversations associated with the trauma  Efforts to avoid activities, places or people that arouse recollections of the trauma  Inability to recall an important aspect of the trauma  Markedly diminished interest or participation in significant activities  Feeling of detachment or estrangement from others  Restricted range of affection  Sense of foreshortened future

9. D URATION Duration of the disturbance (symptoms) is more than one month The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning Functional Significance

10. T WO T YPES Acute: if duration of symptoms is less than three months Chronic: if duration of symptoms is three months or more

11. G ENDER VARIATION A number of epidemiologic survey studies have shown that PTSD is twice as common in women as in men. In addition there are gender differences in…  The type of trauma exposure  Presentation of illness  Comorbidities Some of these differences are clearly societal and non biologically based, it is also clear that biologic systems altered in PTSD may modulated by sex hormones.

12. Rachael Yehuda PhD of the Einstein Medical Center, Bronx, NY discussed the neuroanatomic, neuroendocrine and immune- related bases for various gender differences seen in PTSD. There are also differences between men and women in the presentation of PTSD. Women are more likely to have symptoms of numbing and avoidance and men are more likely to have the associated features of irritability and impulsiveness. Men are more likely to have comorbid substance use disorders Women are more likely to have comorbid mood and anxiety disorders, although many disorders comorbid with PTSD are commonly seen in both men and women. Comorbid: pertaining to two diseases which occur together, such as ADHD and depression

13. S YMPTOMS IN M EN VS. W OMEN Men: Irritability Impulsiveness Substance Abuse Disorders Women: Numbing Avoidance Anxiety/Affec tive Disorders

14. M EN VS. W OMEN Different types of traumas carry different risks for developing PTSD This is one of the reasons why men and women differ in prevalence rates Rape is experienced more often by women and carries one of the highest risks for PTSD Other forms of sexual abuse and interpersonal violences are also more often followed by PTSD than natural disasters or other accidents Socialization Differences: Girls tend to internalize problems, boys externalize

15. B RESLAU ET. A L (1991) Did a longitudal study of 1007 young adults who had been exposed to community violence Found a prevalence rate of 11.3% in women and 6% in men Horowitz et. Al (1995) reviewed a number of studies and found that women have a risk up to five times greater than males to develop PTSD after violent or traumatic events.

16. C OGNITIVE There are differences in the way individuals cognitively process experiences and there may be a difference in attributional styles PTSD patients tend to feel that they have a lack of control over their lives and the world is unpredictable They often experience guilt regarding the trauma Intrusive memories are memories that come to consciousness at random Can be triggered by sounds, smells and/or sights Ex. War Veterans having flashbacks Alberto Rizzo developed a therapeutic tool using virtual reality. It is called virtual Iraq and has changeable variables to change the experience for the patient. This method is based off of flooding, or over- exposure, causing the patient to become accustomed to the trauma.

17. C OGNITIVE Development of PTSD is associated with a tendency to take personal responsibility for failures and to cope with stress by focusing on the emotion Versus facing the problem Sutker et. Al(1995) Found that Gulf War Veterans who had a sense of purpose and commitment to the military had less chance of suffering from PTSD

18. B IOLOGICAL Twin studies show possible genetic predisposition to PTSD Focuses on the neurotransmitter noradrenalin Noradrenalin controls emotional arousal. High levels of noradrenalin cause people to express emotions more openly than others.

19. S OCIOCULTURAL Research suggests that experiences with racism and oppression are predisposing factors for PTSD.

20. R OYSIRCAR (2000) Cites research that among Vietnam War veterans, 20.6% of black and 27.6% of Hispanic veterans met the criteria for a current diagnosis of PTSD, compared to the 13% in white veterans. He takes it a step farther in researching Rwandan children, and argues that the threat of death was the factor evidencing the strongest influence on intrusive thoughts and avoidance of behaviour This just means avoiding situations that can trigger anxiety and panic.

21. R ESEARCH Research in Bosnia supports this in 1998 when close to 73% of girls and 35% of boys suffered from PTSD Kaminer et. Al (2000) stated that the higher rate in girls came from fear of rape Social learning may play a role in PTSD Children may develop PTSD by observing domestic violence

22. C ULTURE In many cultures, it is common for survivors to initiate treatment with someone due to Somatic Complaints Those that have no medical explanation Generally consist of gastrointestinal problems, constipation, heartburn, nausea, vomiting, colitis, migraines, headaches, back aches, and skin disorders thought that these problems, although real to the sufferer, may be brought on by stress or emotional factors. Somatic complaints are difficult to treat because there are no underlying medical issues that are causing them According to the DSM, somatic symptoms of PTSD are typical

23. K LEINMAN (1987) It is irrational and ethnocentric to assume that non- western forms of this disorder are atypical The form commonly seen in the West being assumed as the “norm” Non-Western survivors exhibit Body Memory Symptoms: Lllll One example of this is dizziness experienced by a woman, found to be a body memory of her repeated experience of being forced to drink large amounts of alcohol and then being raped  Sexual abuse is a traumatic experience and that the memory of it can be stored in your physical body. This can be true even if you have no conscious recollection of the abuse.

24. T REATMENT Psychotherapy (Talk Therapy) Medications  People have different ways of overcoming PTSD and the treatment should always be done through the health care provider.

25. P SYCHOTHERAPY Also known as “talk therapy” Occurs with a one-on-one conversation and lasts between 6 and 12 weeks. During psychotherapy, the psychiatrist will use other therapy tactics to help the patient. Different therapy options: Exposure Therapy -It a tactic that involves the patient to face their fear and trauma in a safe way Cognitive Restructuring - helps people make sense of bad memories by helping the patient look at the memory in a realistic way Stress Inoculation Training - tries to reduce symptoms by teaching the person a way to reduce anxiety and helps look at their memories in a healthy way

27. M EDICATION Two medications were approved by the FDA Sertraline(Zoloft) Paroxetine(Paxil) These drugs are antidepressants that help treat depression It helps control symptoms such as sadness, worry, anger, the feel of emptiness Side effects for these drugs include: Headaches Nausea Sleeplessness or drowsiness Agitation Sexual problems
