Mental illness comes from a malfunction in the receptors too much/too little of the chemicals being released Major neuro transmitters – serotonin – low levels = depression, eating disorders Stop the receptors from keeping the passage blocked by giving people a drug that release the uptake inhibitors More serotonin = exercise The workings of the formation- chemical process Genetics
Genetic cont’d and psychological 20:50 (***READING***)Four areas in the psychological perspective: psycho dynamic theory, cognitive behavior theory, family systems theory, humanistic theory 300% increase in the past ten years in the number of children and adolescents taking medication A particular receptor is effective when someone has a panic attack (receptors- release or hold on to chemicals) Basic problems with studies: family’s may influence behaviors – transmit genes BEFORE 1950: Cause of symptoms is generally considered to be in childhood, people create ways to deal with traumas Causes of mental illness : all behaviors are motivated, the motivations may not be obvious (unconscious) Chemical transmissions in the neurons sometimes don’t get sent, the uptake is held in a cell and don’t get transferred over Defense mechanisms: used to preserve ones ego Depression- evidence is more inconsistent – identical twins suggest that its in a similar range as schizophrenia (30-40%) Dominant area of psychology today: cognitive behavior Dynamic concept : the biography of people, an experience that effects their intra working of their mind Electrical shock treatment (treatment of last resort today) most invasive Environmental factors: people being unhappy in a marriage doesn’t mean they should get pills Example : panic attacks are linked to chemicals in the brain Four major means of looking at the brain: MRI CAT scan PET Function MRI
