7
Possession Mental illness as caused by the devil
Widespread religious persecution Exorcisms, burning, beheading, strangling, mutilating

Indicators of Abnormality
Other signs of a disorder are more subtle, and a diagnosis depends heavily on clinical judgment Distress Maladaptiveness Irrationality Unpredictability Unconventionality and undesirable behavior
9
Changing Concepts of Psychological Disorder: The Cognitive-Behavioral Approach
Behavioral perspective – Abnormal behaviors can be acquired through behavioral learning – operant and classical conditioning Cognitive perspective – Abnormal behaviors are influenced by mental processes – how people perceive themselves and their relations with others
10
The Biopsychology of Mental Disorder
Although most psychologists have reservations about the medical model, they do not deny the influence of biology on thought and behavior Organic problems, biochemical imbalances, genetic predispositions
11
Other Perspectives Psychoanalytic Humanistic Sociocultural
CAUSE OF DISORDER: Internal, unconscious conflicts Humanistic CAUSE OF DISORDER: Failure to strive toward one’s potential or being out of touch with one’s feelings Sociocultural CAUSE OF DISORDER: Dysfunctional society
12
How are Psychological Disorders Classified?
The most widely used system, found in the DSM-IV, classifies disorders by their mental and behavioral symptoms
13
Overview of DSM-IV Classification System
DSM-IV – Fourth edition of the Diagnostic and Statistical Manual of Mental Disorders; the most widely accepted classification system in the United States Neurotic disorder or neurosis Psychotic disorder or psychosis A neurotic is a man who builds a castle in the air. A psychotic is the man who lives in the castle. A psychiatrist is the man who collects the rent. – What does this mean?!
14
What causes mood disorders / mental illness?
Researchers believe most serious mental illnesses are caused by complex imbalances in the brain's chemical activity. They also believe environmental factors can play a part in triggering, or cushioning against, the onset of mental illness.
15
Mood Disorders Major depression – Form of depression that does not alternate with mania Seasonal affective disorder (SAD) – Believed to be caused by deprivation of sunlight Bipolar disorder – Mental abnormality involving swings of mood from mania to depression
16
Bipolar Disorder Description:
Extreme mood swings punctuated by periods of generally even-keeled behavior characterize this disorder. Bipolar disorder tends to run in families. This disorder typically begins in the mid-twenties and continues throughout life. Without treatment, people who have bipolar disorder often go through devastating life events such as marital breakups, job loss, substance abuse, and suicide.
17
Symptoms: Mania-expansive or irritable mood, inflated self-esteem, decreased need for sleep; increased energy; racing thoughts; feelings of invulnerability; poor judgment; heightened sex drive; and denial that anything is wrong. Depression-feelings of hopelessness, guilt, worthlessness, or melancholy; fatigue; loss of appetite for food or sex; sleep disturbances, thoughts of death or suicide; and suicide attempts. Mania and depression may vary in both duration and degree of intensity.
18
Formal Diagnosis: Although scientific evidence indicates bipolar disorder is caused by chemical imbalances in the brain, no lab test exists to diagnose the disorder. In fact, this mental illness often goes unrecognized by the person who has it, relatives, friends, or even physicians. The first step of diagnosis is to receive a complete medical evaluation to rule out any other mental or physical disorders. Anyone who has this mental illness should be under the care of a psychiatrist skilled in the diagnosis and treatment of bipolar disorder.
19
Anxiety Disorders Generalized anxiety disorder – Characterized by persistent and pervasive feelings of anxiety, without any external cause Panic disorder – Marked by panic attacks that have no connection to events in a person’s present experience Agoraphobia – Fear of public places/open spaces
20
Anxiety Disorders Phobias– A group of anxiety disorders involving a pathological fear of a specific object or situation Preparedness hypothesis – Notion that we have an innate tendency, acquired through natural selection, to respond quickly and automatically to stimuli that posed a survival threat to our ancestors
21
Anxiety Disorders Obsessive-compulsive disorder – Condition characterized by patterns of persistent, unwanted thoughts and behaviors
22
Common Examples of OCD Common Obsessions: Common Compulsions:

32
Possible Causes of Schizophrenia
Evidence for the causes of schizophrenia has been found in a variety of factors including genetics, abnormal brain structure, and biochemistry Significant Loss of Brain Gray Matter: Individuals with schizophrenia, including those who have never been treated, have a reduced volume of gray matter in the brain, especially in the temporal and frontal lobes. Recently neuroscientists have detected gray matter loss of up to 25% (in some areas). The damage started in the parietal, or outer, regions of the brain but spread to the rest of the brain over a five year period. Patients with the worst brain tissue loss also had the worst symptoms, which included hallucinations, delusions, bizarre and psychotic thoughts, hearing voices, and depression.
33
Enlarged Ventricles in the Brain: Individuals with schizophrenia, including those who have never been treated, typically have enlarged ventricles in the brain, as demonstrated in over 100 studies to date. MRI imaging showing differences in brain ventricle size in twins - one schizophrenic, one not.
34
Diathesis-stress hypothesis –
Genetic factors place the individual at risk, but environmental stress factors transform this potential into an actual schizophrenic disorder Additional environmental exposures (for example, frequent or ongoing social stress and/or isolation during childhood, drug abuse, etc.) then further increase the risk or trigger the onset of psychosis and schizophrenia. Early signs of schizophrenia risk include neurocognitive impairments, social anxiety (shyness) and isolation and "odd ideas".
35
Eating Disorders Anorexia nervosa – Eating disorder involving persistent loss of appetite that endangers an individual’s health – stemming from psychological reasons rather than organic causes Bulimia – Eating disorder characterized be eating binges followed by “purges,” induced by vomiting or laxatives; typical initiated as a weight-control measure
