Chapter 14-Psychological Disorders: ********pg.642-643******** ABNORMAL BEHAVIOUR  The medical model proposes that abnormal behavior is a disease -Diagnosis-distinguishng one illness from another -Etiology-the apparent causation and developmental history of an illness -Prognosis-a forecast about the probable course of an illness -Criteria in making diagnosis: 1. Deviance –behaviour deviates from societal norms 2. Maladaptive Behaviour-judges to have a disorder since their behaniour is impaired (ie.cocaine use) 3. Personal Distress-indivudual reports great personal distress-ie.depression -Stereotypes of Psychology disorders: 1. Incurable 2. Pple with disorders are violent and dangerous 3. Pple behave in biarre ways and are very diff from normal peeps *often it is hard to clearly draw a line btwn normal and abnormality -DSM (Diagnostic and statistical manual of mental disorders)-developed classification system that asks for judgements about individuals on 5 separate dimensions/‟axes‟ – pg.610 -Epidemiology-the study of the distribution of mental or physical disorders in a pop -Prevalence-the % of a pop that exhibits a disorder during a certain time period ANXIETY DISORDERS -defn: a class of disorders marked by feelings of excessive apprehension and anxiety -Types of anxiety disorders: 1. Generalized anxiety disorder-“free-floating anxiety” –a chronic high level of anxiety that is not tied down to any specific threat 2. Phobic disorder-a persistent + irrational fear of an object or situation that presents no realistic danger 3. Panic disorder-recurrent attacks of overwhelming anxiety that usually occur suddenly and unexpectedly. Agraphobia=fear of going out into public places 4. Obsessive-Complusive disorder-persistent, uncontrollable intrusions of unwanted thoughts (obsessions) and urges in sense less rituals (compulsions) 5. Post-Traumatic stress disorder-may appear immediately or months or years after a traumatic event -Biological factors:  Concordance rate-the % of twin pairs or other pairs of relatives who exhibit the same disorder  A moderate genetic predisposition to anxiety disorders  Anxiety sensitivity-make pple more vulnerable to anxiety disorders  Neurotransmitter abnormalities -Cognitive factors:  Pple: 1) misinterpret harmless situations as threatening. 2) focus excessive attention on perceived threats. 3) selectively recall info that seems threatening  Stress SOMATOFORM DISORDERS 1. Somatization disorder-marked by a history of diverse physical complaints that appear to be psychological in origin-mainly women 2. Conversion disorder-a sig loss of physical fxn (with no apparent organic basis), usually in a single organ system-ie. Vision/hearing loss, partial paralysis 3. Hypochondria-excessive preoccupation with health concerns and incessant worry about developing physical illness -Personality factors:  Self-centered, suggestible, excitable, overly dramatic/emotional pple  Neuroticism -Cognitive factors:  Think they are „sick‟  Overinterpret every ache or pain DISSOCIATIVE DISORDERS -pple lose contact with portions of their consciousness or memory, resulting in disruptions in their sense of identity -uncommon -3 syndromes: 1. Dissociative amnesia-a sudden loss of memory of important personal info that is too extensice to be due to normal forettting-ie.memory loss of a single traumatic event (ie.rape) 2. Dissociative fugue-pple lose memory of entire lives, along with sense of personal identity 3. Dissociative identity disorder-“multiple personality disorder”-the coexsistence in one person of 2+ largely complete personalites-ppple are engaging in intentional role-playng to use an exotic mental illness as a face-saving excuse for their personal failings-could also be rooted in emotional trauma that occurred during childhood MOOD DISORDERS -defn:disorders marked by emotional disturbances of varied kinds that may spill over to disrupt physical, perceptual, social, and thought processes -unipolar: experience emotional extreemes at just 1 end of the mood continuum-troubled by depression-more common -bipolar:-emotional extremes at both ends of the continuum-troubled by depression + mania -episodic -disturbed emotion* 1. Major Depressive disorder-pple show persistent feelins of sadness + despair and a loss of interest in previous sources of pleasure. –pple lack energy, anxiety, feel worthless, hoplessess, guilt -Dysthymic disorder:chronic depression that is insufficient in severirt to justify diagnosis if a maor depressive episode -prevalence is increasing (2x as much in women than men-women have a greater tendency to dwell on stuff then men) 2. Bipolar disorder-“manic-depressive disorder”-experience periods of both manic/depression -Cyclothymic disorder:pple exhibit chronic but relatively mild symptoms of bipolar disturbance -seen equally in males and females -average age of onset=25 -Seasonal Affective Disorder (SAD)-type of depression that follows a seasonal pattern and postpartum depression, a type of depression that sometimes occurs after childbirth -related to circadium rhythms and melatonin production -can be a dehibilitating disorder -closely correlated with suicide -Factors:  Genetic vulnerability/predisposition  Biological and neurochemical factors -neurochemical abnormalities -neurogenesis-brain continues to
