Document Summary
Diathesis- stress models p. 28- lead to disorder which makes vulnerable to certain behaviors (drug abuse) Diathesis (vulnerability in child development) genetic predisposition toward an abnormal or diseased condition. Biological factors (genes, brain anomalies), social factor (maladaptive upbringing, chronic stress), Bio trigger (onset of a disease, exposure to toxins), social trigger (traumatic event, major loss), Psych trigger (perceived loss of control, violate trust) Brain dysfunction- abnormalities in the structure of the brain cause mental disorders: can occur in three areas from injury/ deterioration: cerebral cortex (controls advance thought process, decision making) hypothalamus (controls emotions ex. Biochemical imbalances- imbalances in the levels of neurotransmitters or hormones, or poor functioning of receptors cause mental disorders. Genetic abnormalities- disordered genes lend to mental disorders. 4 lobes of the cortex (physiological and functional separation) Occipital lobe- controls vision, back of brain. Corpus callosum- thick nerve that allows transmissions between left and right side of brain.
