Unit 5 Notes Module 22: Assessment and Anxiety Disorders
Causes of Mental Disorders • Medical Model Approach • Looking for biochemical, neurological, or genetic causes of behavior • Mental disorders are similar to a physical illness • Psychiatrists use drugs (psychoactive) to treat mental disorders • Cognitive-Behavioral Approach
Disorders result from deficits in cognitive processes (faulty thoughts, attitudes, and beliefs) and behavioral problems (deficits in skills and abilities) • Treatment focuses on hanging a person’s maladaptive thoughts and behaviors • Psychoanalytic (dynamic) Approach • Disorders are due to unconscious (repressed) conflicts or problems with unconscious conflicts at one of Freud’s psychosexual stages
Treatment centers on the therapist’s helping the patient identify and solve his/her unconscious conflicts
Defining Mental Disorders: 3 Approaches • Statistical Frequency • A behavior may be considered abnormal if it occurs rarely or infrequently in relation to behaviors of the general people • Social Norms • Abnormal behavior deviates greatly from accepted social standards, values, or norms • Norms change over time (men wearing earrings and thin women)
Maladaptive Behavior • Abnormal behavior interferes with the individual’s ability to function in his/her personal life or in society • Mental health professionals find this the most useful definition of abnormal behavior
Assessing Mental Disorders • Clinical assessment: systematic evaluation of an individual’s various psychological, biological, and social factors • Identifying past and present problems, stresses, or other systems
3 Methods of Assessment • Neurological Tests • Check for brain damage or malfunction (MRI) • Evaluate reflexes, motor coordination and brain structures/functions • Clinical Interviews • Gathering information about a person’s past and current behaviors, beliefs, attitudes, emotions, and problems • Structured interviews follow a standard format of questions
Unstructured interviews have no set questions • Psychological Tests • Objective: specific statements of questions (self-report questionnaires-MMPI) • Projective: ambiguous stimuli that a person interprets or makes up a story about (Ink-blot and TAT)
DSM-IV-TR • Diagnostic and Statistical Manual of Mental Disorders-IV-Test Revision • Describes a uniform system for assessing specific symptoms and matching them to almost 400 different mental disorders • 3 Advantages • Helps professionals communicate • Researchers use the classification system to study and explain mental disorders
Therapists use the classification system to design a treatment program that best fits their client’s needs • Steps in Making a Clinical Diagnosis • 1) Clinical Interview, Personality tests, and neurological test • 2) Clinical Assessment: Identify symptoms • 3) DSM-IV-TR: Use symptoms to diagnose mental disorders
Anxiety Disorders • 1) Generalized Anxiety Disorder (5% of adults) • Characterized by excessive or unrealistic worry about almost everything or feeling that something bad is about to happen • Anxious feelings occur on most days for at least 6 months • Symptoms • Psychological: being irritable, poor concentration, constant worrying
Physical: restlessness, easily fatigued, sweating, flushing, pounding heart, insomnia, clammy hands, headaches, and muscle tension/aches • Treatment • Psychotherapy • Drugs (benzodiazepines-tranquilizers) • 2) Panic Disorders • Characterized by recurrent and unexpected panic attacks
Intense worrying interferes with normal psychological functioning • Symptoms • Pounding heart, sweating, trembling, shortness of breath, feelings of choking, chest pain, nausea, dizziness, fear of losing control or dying • Treatment (a combo of) • Benzodiazepines (tranquilizers), antidepressants and psychotherapy • May take 3-8 months
3) Phobias • Characterized by an intense and irrational fear that is out of all proportion to the possible danger of the object or situation • Fear is accompanied by physiological arousal • Person goes to great lengths to avoid the feared object/event • Types • Social – characterized by irrational, marked, and continuous fear or performing in social situations
Individuals fear they will humiliate or embarrass themselves • Ex. Speaking in public, to strangers, eating in public, etc… • Specific – marked and persistent fears that are unreasonable and triggered by anticipation of, or exposure to, a specific object or situation • Ex. Bugs, snakes, etc…, heights, water, closed places
Agoraphobia – anxiety about being in places or situations from which escape might be difficult or embarrassing • Ex. Public transportation, bridges or tunnels, crowds, going out by one’s self, elevators, etc… • Treatment • Cognitive-Behavior Therapy • Changing negative or distorted beliefs by substituting positive, healthy, realistic beliefs
Changing limiting or descriptive behaviors by learning and practicing new skills to improve function • Exposure Therapy (combined with Cognitive-Behavior Therapy) • Gradually exposing the person to real anxiety producing situations or objects • When the combination therapy doesn’t help, use drug therapy or virtual reality therapy
Drug Treatment • Benzodiazepines (tranquilizers) • Anti-depressants • 4) Obsessive-Compulsive Disorder (OCD) (3%) • Having continued thoughts/urges about performing a certain act over and over again • Symptoms • Obsessions: repeated thoughts/urges a person can’t control • Compulsions: repeated actions of some senseless behaviors or rituals over and over
Ex. Hand washing, checking things, counting, putting things in order, cleaning, hoarding, perfectionists, harming obsession • Evidence suggests that an imbalance of brain chemicals (serotonin) may be at the root of OCD • Treatment • Exposure therapy • Anti-depressant drugs • Book: Brain Lock • Videos: What About Bob?, As Good As It Gets
Somatoform Disorders (Freud called this Hysteria) • A pattern of recurring, multiple and significant bodily symptoms that extend over several years • Bodily symptoms are believed to be caused by psychological factors • These disorders are rare
Somatoform Disorder- multiple symptoms appearing before age 30 that have no physical cause, but are believed to be triggered by psychological problems or disorders • Women are 5 times more likely to report than to men
Conversion Disorder- Psychological trauma triggers a physical dysfunction • These parents aren’t faking it • Symptoms: blindness, paralysis, deafness, etc…
Mass Hysteria- a condition experienced by a group of people who, through suggestion, observation, or other psychological processes, develop similar fears, delusions, abnormal, behavior, or physical symptoms
Hypochondriasis- excessive concern about one’s health Ex. Slight headache = brain cancer Sniffles = pneumonia • Spend a lot of time in the doctor’s office
Module 23: mood disorder and schizophrenia • Mood Disorders- prolonged and disturbed emotional states that affect most all of a person’s thoughts, feelings, and behaviors
Kinds of Mood Disorders • Major Depression -Marked by at least 2 weeks of continually being in a bad mood, having no interest in anything and getting no pleasure from activities
Must have at least 4 of the following symptoms: • Problems with eating, sleeping, thinking, concentrating, or making decisions, lacking energy, thinking about suicide, feeling worthless or guilty
Bipolar I Disorder (manic depressive disorder) • Marked by fluctuations between episodes of depression and mania • A manic episode: • Goes on for at least a week • Person is usually euphoric • Has great self esteem, little need for sleep, speaks rapidly, easily distracted, has racing thoughts, and pursues pleasurable activities
Dysthymic Disorder (Moderate Depression) • Affects about 6% of the population • Being chronically, but not continually depressed for a period of 2 years (“down in the dumps”) • While depressed, person experiences at least 2 of the following symptoms: Poor appetite, insomnia, fatigue, low self-esteem, poor concentration, and feelings of hopelessness
Causes of Mood Disorders • Biological Theory Of Depression • Emphasize underlying genetic, neurological or physiological factors that may predispose a person to develop a mood disorder
Genetic Factors • Identical Twins 80% • Fraternal Twins 16% • Neurological Factors • Chemical defect in the brain-serotonin (helps keep brain active in people)
Excessive Levels = Mania • Low levels = depression • Brain Scans • Prefrontal cortex (planning and deciding functions) was about 40% smaller and less active in depressed patients
2.) Psychosocial Factors • Are believed to interact with biological factors that combine to put one at risk for developing a mood disorder • They include: personality traits (social dependent personality and achievement personality), amount of social support and ability to deal with stresses
3.) Beck’s Cognitive Theory Of Depression • When we are feeling down, automatic, negative thoughts that we rarely notice occur continually throughout the day • The negative thoughts distort how we perceive and interpret the world • As a result, the negative thoughts contribute to feeling depressed
Major Depression and Dysthymic Disorder: Treatment • Antidepressant Drugs • Act by increasing levels of a specific group of neurotransmitters (such as monoamines, serotonin) that is believed to be involved in the regulation of emotions and moods
SSRIs (selective Serotonin Reuptake Inhibitors) • Raise levels or serotonin • Prozac
Psychotherapy • For patients with less severe depression, this was as effective as antidepressant drugs • For patients with more severe depression, a combination of antidepressant drugs and psychotherapy as more effective than either one alone
Electroconvulsive therapy (ECT) • Involves placing electrodes on the skull and administering a mile electrical shock that passes through the brain and causes seizures • Usual treatment consists of 10-12 ECT sessions, 3 times per week
Memory loss is a serious side effect • Used as a “last resort” • Reduces depressive symptoms in about 60-80% of patients
Bipolar I Disorder: Treatment • Lithium • A naturally occurring mineral salt • Most effective treatment for Bipolar I because it reduces or prevents manic episodes
Personality Disorders • Inflexible, long-standing, maladaptive traits that cause significantly impaired functioning or great distress in one’s personal and social life
Antisocial Personality Disorder • Chronic delinquents up to serial killers • Patterns of disregarding the rights of others without feeling guilt or remorse • Known as psychopaths or sociopaths
2 Characteristics • Pattern or disregard for or violation of the rights or properties of others (they may steal, harass, or beat people, destroy property, kidnap, or kill) • Dishonesty, lying or deceitful manipulation of others • Don’t learn from experience
Psychopaths: Causes and treatments • Psychological Factors • Aggressive and antisocial as a child • Parents found child almost impossible to control • Physical or sexual abuse in childhood
Biological Factors • Twin and adoption studies show that genetic factors contribute 30-50% to the development of antisocial personality disorders • Evidence from neurobiological factors comes from brain scans that show fewer brain cells in the prefrontal cortex of people with antisocial personality disorder
Treatment • Psychotherapy has been ineffective • Antidepressant drugs help reduce aggressive behaviors, but once medications stop, aggressiveness resurfaces
*Borderline Personality Disorder • *Char.’s: these people form intense relationships • -they are very dependent and clingy (emotionally needy), but they deny it • -they sabotage relationships • They are self-destructive (accidents, suicidal gestures) • -they are manipulatives • Ex. Girl Interrupted, Cable Guy
Schizophrenia • Affects about 2% of the population • About 30% or mental hospital admissions are for this disorder (the highest percent fo any disorder) • Involves loss of contact with reality
Serious mental disorder that lasts for at least 6 months • Includes at least two of the following symptoms:
