Presentation Transcript

  1. Multidimensional Integrative Approach to Psychopathology

  2. Multidimensional Models of Psychopathology Social Influences Biological Influences Behavioral Influences Cognitive & Emotional Influences

  3. Genes and Psychopathology • No single gene • Inherit Predispositions, not Psychological Disorders

  4. Gene-Environment Interactions • Diathesis-Stress Model • Inherit Tendencies (Diathesis) • Tendencies Activated (Stress) • Schizophrenia, Substance Abuse, Blood-Injection-Injury Phobias

  5. Neuroscience Perspective • Primarily looks at central nervous system (brain and spinal cord) and its “communicators”

  6. The Neuron

  7. Neurotransmitters: The Chemical Messengers • Norepinephrine (noradrenaline) • Serotonin • Dopamine • Gamma Aminobutyric Acid (GABA) • Major Neurotransmitters in Psychopathology

  8. Neurotransmitter Functions • Dopamine • Pleasure-Seeking • Schizophrenia (too much) • Parkinson’s Disease (too little) • L-DOPA (Agonist)

  9. Behavioral Genetics & Gene-Environment Interactions • Pedigree Studies • “Family Tree” • Twin Studies • Identical vs Fraternal • Adoption Studies • More Compelling Approach

  10. Examples of cognitive-behavioral influences Depressogenic thought patterns Reinforcement patterns (e.g., alcoholism, phobias) Conduct disorder developing into anti-social personality disorder (lack of punishment? brain-environment interaction?)

  11. Social-Interpersonal Influences • Lack of Social Support • Depression and Suicide • Illness and Suppressed Immune Function • Variety of Other Disorders • Increasing Social Support Helps • Interpersonal Psychotherapy (IPT) • Support groups / Group therapy
