Cognitive Behavioral Books focused on specific problems
Schizophrenia is most serious psychological dysfunction • Diathesis-Stress Model: Born with genetic defect that predisposes them to overreact to stressors OR • Early severe stressful events cause abnormal neurodevelopment that has caused nervous system to be hyper sensitive to stressors
Abnormalities found in schizophrenics • Over-reactivity of hypothalamic-pituitaryadrenal axis • Structural brain changes, including hippocampus damage and cerebral atrophy • Elevation of release of cortisol and dopamine when exposed to stress
What could these neurological abnormalities explain? • Oversensitivity to stress • Cognitive impairments • Relationship between psychotic and hallucinations, delusions and paranoia
Problem with biological model • Impede adequate consideration of relevance of stress, trauma, neglect and loss in early childhood • Diathesis-stress model only measure stressors a few weeks or months prior to outbreak so not consider early life events • Gross imbalance in examining biological psychological and social factors
“Genotype-environment interaction in schizophrenic-spectrum disorder” • British Journal of Psychiatry (2004) • 36% of high-genetic risk adoptees raised in dysfunctional families develop symptoms • 5. 8% of high-genetic risk adoptees raised in healthy families • Demonstrates protective effect of family
Factors in Environment: High Degree of Stress Early in Life • Genetic risk combined with volatile, hostile unpredictable, judgmental and/or overly protective environment
Healthy Families • Have good sense of humor and can laugh at themselves • Respect each other’s need for privacy and not engage in mind reading • Negotiate and compromise
Findings of Adoptee studies • Genes do not operate alone • Environmental factors play a significant role • Much of environmental influences are result of family environment • Developing brain vulnerable early in life
