A male with a Hx of Schizophrenia, Chronic Paranoid type diagnosed at age 25 currently lives with his daughter in Brooklyn. • Medical Hx : HTN, DM, Hypercholesterolemia • Substance abuse Hx : Alcohol Dependence Nicotine Dependence • Psycho-social Hx : Gang member at age 15 No close friends/family members Financial stressors • Trauma Hx: Multiple physical assaults Witness to murder Nightmare’s and Flashbacks

  4. Questions for the Audience 1) Is there an association between Mr. Smith’s positive psychotic symptoms and his history of trauma? □ Yes □ No □ Maybe 2) Which of these factors could be most associated with Mr. Smith’s history of trauma and current psychosis compared to those without Hx of trauma? A. ETOH use B. Social isolation C. Financial Strain D. Physical Illness E. PANSS negative symptoms F. All of the Above G. None of the Above

  5. Introduction • No documented data has been found on the relationship between trauma and psychosis in the elderly schizophrenic population. • Trauma has been shown to have a significant relationship with psychosis in younger persons with schizophrenia particularly with positive symptoms. • Prior research has suggested that many individuals with schizophrenia have been exposed to significant trauma, not only after but also prior to the onset of illness.

  6. Psycho-Analytic Perspective • Charcot's "traumatic hysteria"

  7. Eugene Bleuler ‘The Schizophrenias’(Bleuler E. Dementia praecox or the group of schizophrenias. New York, NY: International Universities Press, 1911/1950.)

  8. Trauma: "An event in the subject's life, defined by its intensity, by the subject's incapacity to respond adequately to it and by the upheaval and long-lasting effects that it brings about in the psychical organization". • Repetition Compulsion:

  9. Object Relations Theory: Paranoid-Schizoid ↕ Depressive

  10. Cognitive-Behavioral Perspective • Negative beliefs about self, world and others (such as ‘I am vulnerable’ and ‘Other people are dangerous’) have been shown to be associated with the development of psychotic experiences. Read et al (2004), Garety et al (2001) • A more recent study has shown that such beliefs specifically formed as a result of trauma are related to psychotic experiences in patients. KilCommons et al (2005)

  11. There have been several suggestions that there is a sub-group of schizophrenia that is trauma-induced and characterized by a predominance of positive symptoms. Kingdom, Turkington (2004) and Ross (2004) • “Traumatic Psychosis” is described as an entity in which trauma has a distinct and specific role in terms of the onset and content of psychotic symptoms. Kingdom, Turkington (2004)

  12. Biological Perspective • Diathesis-Stress Model: Genetic Vulnerability  Hypersensitivity to Stress • Traumagenic Neurodevelopmental Model: Read et al (2001) Trauma  HPA activation  ACTH  Glucocorticoids   Impaired negative feedback  Changes in Hippocampus HPA Activation  Augments DA synthesis and receptors

  13. Similarities between effects of traumatic events on the developing brain and the biological abnormalities in Schizophrenia • Overactivity of HPA • Dopamine, Norepinephrine & Serotonin Abnormalities • Hippocampal damage • Cerebral atrophy • Ventricular enlargement • Reversed cerebral asymmetry

  14. Exploring the relationship between trauma and psychosis in Younger Population • A research in Netherlands study involving 4045 subjects aged 18–64 found that those who had experienced emotional, physical, or sexual abuse or neglect before the age of 16 were more likely to report experiencing psychotic symptoms during a 3-year follow-up period. Janssen et al (2004) • A British study of 8580 subjects aged 16–74 found that those who met criteria for a definite or probable psychotic disorder were over 15 times more likely to have been sexually abused at some point in their lifetime. Bebbington et al (2004)

  15. A large population-based study (n = 17,337) found that respondents reporting a history of hallucinations were more likely to have been both physically and sexually abused during childhood. Whitfield at al (2005) • A more recent study on 2524 subjects aged 14–24 found that the experience of any lifetime trauma, not restricted to childhood was associated with the development of 3 or more psychotic symptoms. Spauwen et al (2006) • In the schizophrenia group a history of trauma was significantly related to poor communication skills and depressive symptoms. Spence et al (2006)

  16. PTSD and Schizophrenia: Similarities and Differences • Psychotic Features in Chronic Posttraumatic Stress Disorder and Schizophrenia: Comparative Severity Hamner et al (2000) 1)Schizophrenic patients had more severe delusions and conceptual disorganization. 2)Severity of hallucinations and suspiciousness/persecution were identical between the two groups. 3)PANSS negative symptoms and global psychopathology subscales were comparable between the two groups.

  17. Study Hypothesis • Primary There is an association between trauma and positive symptoms in elderly Schizophrenic patients. • Secondary The associated socio-demographic and clinical factors continue to have a significant impact on the relationship between trauma and positive symptoms in the elderly Schizophrenic population.

  18. Methods • Schizophrenia (S) Group -198 person’s age 55 + who developed schizophrenia before age 45. -39 % Living Independently -61 % Living in supported community residences • Community (C )Comparison Group -113 persons derived from random block sampling. -Well matched with schizophrenia sample for age, gender and race.

  19. Exclusion : Persons with substantial cognitive impairment. • Scales Used: 1) Trauma and Victimization scale (12 Items) - Measures frequency of trauma ( 0 to 3) - Stress caused due to trauma ( 0 to 3) 2) Other Scales PANNS, DRS, CESD, IADL, Acute Stressor’s Scale,Religiosity Scale, Social network (NAP)

  20. Dependant variables The Trauma score was computed by multiplying the frequency of traumatic events with the degree of stress. Using a median cut-off score on the trauma scale, the trauma group was dichotomized into persons scoring in the Low Trauma Group(3 and below)and High Trauma Group(4 +). • Independent variables 17 independent variables were used in the study based on literature review and earlier findings.

  21. ResultsTable 1. C Group(n = 113) V/S S Group (n = 198)

  22. Table 2. Bivariate Analysis of Trauma among older adults with Schizophrenia

  23. Bivariate Analysis • Significant variables: High Trauma Group 1)Higher PANSS positive scores 2)Higher PANSS anxiety scores 3)Higher CESD scores (syndromal depression) 4)Higher ETOH consumption 5)Greater amount of Physical Illnesses 6)Greater use of Spiritualists 7)More Acute Stressors 8)Higher proportion of intimate contacts 9)Increased financial strain

  24. Table 3. Logistic Regression Analysis: 17 independent variables

  25. Logistic Regression • Significant Variables: High Trauma Group 1) Higher PANSS positive symptoms 2) Higher ETOH consumption

  26. Right Answers 1) Is there an association between Mr. Smith’s positive psychotic symptoms and his history of trauma? • YES 2) Which of these factors could be most associated with Mr. Smith’s history of trauma and current psychosis compared to those without Hx of trauma? • A.ETOH use B. Social isolation C. Financial Strain D. Physical Illness E. PANSS negative symptoms F. All of the Above G. None of the Above

  27. Discussion • The strong association between trauma and positive symptoms exists in elderly persons with Schizophrenia. • Ongoing and continuing trauma seems to have a significant impact on positive symptoms in schizophrenia in later life, although it is possible that increased positive symptoms may lead to more traumatic events. • The increased alcohol consumption significant in the study has been reported in studies done in younger populations. However, its impact on the elderly with multiple co-morbid medical illnesses merits serious considerations.

  28. Patients may be prone to exacerbation and maintenance of their psychotic experiences through being traumatized by the subjective experience of psychosis or through subsequent victimization in the community. • Being in the high trauma group pre-disposes the individuals to a greater burden of psychopathology, increased ETOH consumption and possibly increased anxiety, depression, physical illnesses, social isolation and financial strain.

  29. In Bivariate analysis, Syndromal depression was significantly higher in high trauma group (39%)as compared to low trauma group (25%). • PANSS negative symptoms did not achieve significance in this study.

  30. Strengths and Limitations • Strengths: • Multivariate Analysis • Multiracial Sample • Bio-psycho-social model • Limitations: • Cross sectional design • Self report of trauma • One geographic location

  31. Clinical Implications • Biological Interventions: • SSRIs • Second Generation Anti-psychotics • Anti-convulsants • Monitoring ETOH and Substance abuse • Monitoring co-morbid medical illnesses

  32. Psychological Interventions: • Cognitive Behavior Therapy for Psychosis -Psycho-education -Identify links between traumatic experience and current psychotic symptoms  Normalize their experience, reduce distress and increase perceived control. -Voice Dairies, coping strategies and rational responding to critical hallucinations  reduces symptom burden and depression. • Eye Movement Desensitization and Reprocessing (EMDR) • Group Therapy

  33. Social Interventions: • Family Therapy • Educating staff at Residential Programs

  34. Summary • There is a strong association between trauma and positive psychotic symptoms in older adults with Schizophrenia. • The study results underscore the value of a thorough review of current and lifetime trauma in older persons with schizophrenia. • The findings of this study suggest more targeted psychotherapeutic and pharmacological interventions may be required for persons in the high trauma group.
