WARNING SOME OF THE TOPICS AND SYMPTOMS COVERED IN THIS CHAPTER YOU MAY HAVE FELT OR EXPERIENCED AT ONE TIME HOWEVER, IT IS NOT LIKELY THAT YOU HAVE A PSYCHOLOGICAL DISORDER!!
Remember…
Psychological Disorders People are fascinated by the exceptional, the unusual, and the abnormal. This fascination may be caused by two reasons: 9 1. During various moments we feel, think, and act like an abnormal individual. 2. Psychological disorders may bring unexplained physical symptoms, irrational fears, and suicidal thoughts.
Psychological Disorders To study the abnormal is the best way of understanding the normal. William James (1842 -1910) 10 1. There are 450 million people suffering from psychological disorders (WHO, 2004). 2. Depression and schizophrenia exist in all cultures of the world.
Psychological Disorders About 26. 2 percent of Americans ages 18 and older — about one in four adults — suffer from a diagnosable mental disorder in a given year About 6 percent of American adults suffer from a serious mental illness such as bipolar disorder, schizophrenia, and clinical depression.
Defining Psychological Disorders Mental health workers view psychological disorders as persistently harmful thoughts, feelings, and actions. When behavior is deviant, distressful, and dysfunctional psychiatrists and psychologists label it as disordered (Comer, 2004). 12
What is Abnormal? What is the content of the behavior? I stop bathing I shower 37 times every day What is the sociocultural context in which the behavior occurs? We are expected to not smell We are expected to show up to work on time What are the consequences of the behavior for that person and for others? People avoid me I get fired from my job
Deviant, Distressful & Dysfunctional 1. Deviant behavior Carol Beckwith (going naked) in one culture may be considered normal, while in others it may lead to arrest. 2. Deviant behavior must accompany distress. 3. If a behavior is dysfunctional it is clearly a disorder. In the Wodaabe tribe men wear costumes to attract women. In Western society this would be considered abnormal. 14
Handout Out 12 -2 Defining Psychological disorder (back of Ch. 12 Facts & falsehoods)
Understanding Psychological Disorders Ancient Treatments of psychological disorders include trephination, exorcism, being caged like animals, being beaten, burned, castrated, mutilated, or transfused with animal’s blood. John W. Verano Trephination (boring holes in the skull to remove evil forces) 16
The Medical Model Philippe Pinel (1745 -1826) from France, insisted that madness was not due to demonic possession, but an ailment of the mind. George Wesley Bellows, Dancer in a Madhouse, 1907. © 1997 The Art Institute of Chicago Dance in the madhouse. 17
Medical Model When physicians discovered that syphilis led to mental disorders, they started using medical models to review the physical causes of these disorders. 1. 2. 3. 4. Etiology: Cause and development of the disorder. Diagnosis: Identifying (symptoms) and distinguishing one disease from another. Treatment: Treating a disorder in a psychiatric hospital. Prognosis: Forecast about the disorder. 18
The Biopsychosocial Approach Assumes that biological, socio-cultural, and psychological factors combine and interact to produce psychological disorders. 19
Classifying Psychological Disorders The American Psychiatric Association rendered a Diagnostic and Statistical Manual of Mental Disorders (DSM) to describe psychological disorders. The most recent edition, DSM-IV-TR (Text Revision, 2000), describes 400 psychological disorders compared to 60 in the 1950 s. 20
Multiaxial Classification Axis II Is a Clinical Syndrome (cognitive, anxiety, mood disorders [16 syndromes]) present? Is a Personality Disorder or Mental Retardation present? Axis III Is a General Medical Condition (diabetes, hypertension or arthritis etc) also present? Axis IV Are Psychosocial or Environmental Problems (school or housing issues) also present? What is the Global Assessment of the person’s functioning? Axis V 21
Multiaxial Classification Note 16 syndromes in Axis I 22
Multiaxial Classification Note Global Assessment for Axis V 23
Mnemonic Device 5 axis of the DSM-IV-TR. They are as follows: Clinical, Personality, Medical, Psychosocial, and GAF (Global) Can Pretty Molly Please Get Abby Fit?
Goals of DSM 1. 2. Describe (400) disorders. Determine how prevalent the disorder is. Disorders outlined by DSM-IV are reliable. Therefore, diagnoses by different professionals are similar. Others criticize DSM-IV for “putting any kind of behavior within the compass of psychiatry. ” 25
Labeling Psychological Disorders 1. Critics of the DSM-IV argue that labels may stigmatize individuals. Elizabeth Eckert, Middletown, NY. From L. Gamwell and N. Tomes, Madness in America, 1995. Cornell University Press. Asylum baseball team (labeling) 26
Labeling Psychological Disorders 2. Labels may be helpful for healthcare professionals when communicating with one another and establishing therapy. 27
DSM-V For more information
Labeling Psychological Disorders 29 Elaine Thompson/ AP Photo 3. “Insanity” labels raise moral and ethical questions about how society should treat people who have disorders and have committed crimes. Theodore Kaczynski (Unabomber)
Anxiety Disorders Feelings of excessive apprehension and anxiety. 1. 2. 3. 4. 5. 30 Generalized anxiety disorder Panic disorder Phobias Obsessive-compulsive disorder Post-traumatic stress disorder
Generalized Anxiety Disorder Symptoms 1. Persistent and uncontrollable tenseness and apprehension. 2. Autonomic arousal. 3. Inability to identify or avoid the cause of certain feelings. 32
Panic Disorder Symptoms Minutes-long episodes of intense dread which may include feelings of terror, chest pains, choking, or other frightening sensations. Anxiety is a component of both disorders. It occurs more in the panic disorder, making people avoid situations that cause it. 33
Phobias Marked by a persistent and irrational fear of an object or situation that disrupts behavior. 34
Kinds of Phobias Agoraphobia Acrophobia Claustrophobia Hemophobia Phobia of open places. Phobia of heights. Phobia of closed spaces. Phobia of blood. 36
Obsessive-Compulsive Disorder Persistence of unwanted thoughts (obsessions) and urges to engage in senseless rituals (compulsions) that cause distress. 37
Brain Imaging A PET scan of the brain of a person with Obsessive-Compulsive Disorder (OCD). High metabolic activity (red) in the frontal lobe areas are involved with directing attention. Brain image of an OCD 39

OCD ACTIVITY
Post-Traumatic Stress Disorder Four or more weeks of the following symptoms constitute post-traumatic stress disorder (PTSD): 1. Haunting memories 2. Nightmares 3. Social withdrawal Bettmann/ Corbis 4. Jumpy anxiety 5. Sleep problems 42
Resilience to PTSD Only about 10% of women and 20% of men react to traumatic situations and develop PTSD. Holocaust survivors show remarkable resilience against traumatic situations. All major religions of the world suggest that surviving a trauma leads to the growth of an individual. 43
Explaining Anxiety Disorders Freud suggested that we repress our painful and intolerable ideas, feelings, and thoughts, resulting in anxiety. 44
The Learning Perspective 45 John Coletti/ Stock, Boston Learning theorists suggest that fear conditioning leads to anxiety. This anxiety then becomes associated with other objects or events (stimulus generalization) and is reinforced.
The Learning Perspective Investigators believe that fear responses are inculcated through observational learning. Young monkeys develop fear when they watch other monkeys who are afraid of snakes. 46
The Biological Perspective Natural Selection has led our ancestors to learn to fear snakes, spiders, and other animals. Therefore, fear preserves the species. Twin studies suggest that our genes may be partly responsible for developing fears and anxiety. Twins are more likely to share phobias. 47
The Biological Perspective Anterior Cingulate Cortex of an OCD patient. 48 S. Ursu, V. A. Stenger, M. K. Shear, M. R. Jones, & C. S. Carter (2003). Overactive action monitoring in obsessive-compulsive disorder. Psychological Science, 14, 347 -353. Generalized anxiety, panic attacks, and even OCD are linked with brain circuits like the anterior cingulate cortex.
Somatoform Disorders (somatic) Bodily symptoms without physical cause Examples: Conversion Disorder & Hypochondraisis
Dissociative Disorders Conscious awareness becomes separated (dissociated) from previous memories, thoughts, and feelings. Symptoms 1. Having a sense of being unreal. 2. Being separated from the body. 3. Watching yourself as if in a movie. 51
Dissociative Identity Disorder (DID) A disorder in which a person exhibits two or more distinct and alternating personalities, formerly called multiple personality disorder. Lois Bernstein/ Gamma Liason Chris Sizemore (DID) 52
Dissociative Identity Disorder (DID) EXTREMELY RARE! But the number of cases is on the rise. (Why? ) In true DID the personalities are distinct people, with their own names, identities, mannerisms, speaking voices, and even IQs!
Origins of DID Childhood abuse – child copes with the abuse by assigning it to another person and thus dissociates themselves. 3/4 ths of all MI cases have child abuse. Prevalence of child personalities in DID seem to support this. Some believe this is not real and it is an elaborate role play – but the various personalities have different blood pressure readings, different responses to medication, different allergies, different vision problems and different handedness, and maybe even brainwave patters.
DID Critics argue that the diagnosis of DID increased in the late 20 th century. DID has not been found in other countries. Critics’ Arguments 1. Role-playing by people open to a therapist’s suggestion. 2. Learned response that reinforces reductions in anxiety. 55
DSM Criteria: DID cont A. The presence of two or more distinct identities or personality states B. At least two of these identities or personality states recurrently take control of the person’s behavior C. Inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness D. Not due to a GMC or substance
DID cont May be seen through: Various personalities don’t know they inhabit the same body. Sometimes they know of the other people and make disparaging comments about them. They usually are very different as if the various aspects of the person are represented by various personalities. Almost always one of the personalities is a child.
Other Dissociative Disorders Dissociative Amnesia Key features– loss of memory for past events without a biological reason. Can be a defense mechanism. Is usual selective. Total amnesia is very rare. One or more episodes of inability to recall important personal information, usually of a traumatic or stressful nature, that is too extensive to be explained by ordinary forgetfulness Not better explained by a another mental disorder and is not due the brain or substance Symptoms cause clinically significant distress or impairment in functioning
Other Dissociative Disorders Dissociative Fugue Extreme and rare, involves flight from home and the assumption of a new identity, with amnesia for past identity and events. Sudden, unexpected travel away from home or one’s customary place of work, with inability to recall one’s past Confusion about personal identity or assumption of a new identity (partial or complete) Not better explained by a another mental disorder and is not due to the brain or substance Symptoms cause clinically significant distress or impairment in functioning
Mood Disorders Emotional extremes of mood disorders come in two principal forms. 1. Major depressive disorder 2. Bipolar disorder 60
Major Depressive Disorder Depression is the “common cold” of psychological disorders. In a year, 5. 8% of men and 9. 5% of women report depression worldwide (WHO, 2002). Blue mood Major Depressive Disorder Gasping for air after a hard run Chronic shortness of breath 61
Major Depressive Disorder Major depressive disorder occurs when signs of depression last two weeks or more and are not caused by drugs or medical conditions. Signs include: 1. 2. 3. 4. 63 Lethargy and fatigue Feelings of worthlessness Loss of interest in family & friends Loss of interest in activities
Bipolar Disorder Formerly called manic-depressive disorder. An alternation between depression and mania signals bipolar disorder. Depressive Symptoms Manic Symptoms Gloomy Elation Withdrawn Euphoria Inability to make decisions Desire for action Tired Hyperactive Slowness of thought Multiple ideas 64
Bipolar Disorder Many great writers, poets, and composers suffered from bipolar disorder. During their manic phase creativity surged, but not during their depressed phase. Clemens Hemingway Earl Theissen/ Hulton Getty Pictures Library The Granger Collection 65 Wolfe George C. Beresford/ Hulton Getty Pictures Library Bettmann/ Corbis Whitman
Bipolar Self screening http: //www. aboutdepressionfacts. com/bipolar-disorder -self-screening-test-infographic. html
Explaining Mood Disorders Since depression is so prevalent worldwide, investigators want to develop a theory of depression that will suggest ways to treat it. Lewinsohn et al. , (1985, 1998) note that a theory of depression should explain the following: 1. Behavioral and cognitive changes 2. Common causes of depression 67
Theory of Depression 3. Gender differences 68
Theory of Depression 4. Depressive episodes self-terminate. 5. Stressful events often precede depression. 6. Depression is increasing, especially in the teens. Desiree Navarro/ Getty Images 69 Post-partum depression
Biological Perspective Genetic Influences: Mood disorders run in families. The rate of depression is higher in identical (50%) than fraternal twins (20%). 70 Jerry Irwin Photography Linkage analysis and association studies link possible genes and dispositions for depression.

Social-Cognitive Perspective The social-cognitive perspective suggests that depression arises partly from self-defeating beliefs and negative explanatory styles. 72
Depression Cycle 1. Negative stressful events. 2. Pessimistic explanatory style. 3. Hopeless depressed state. 4. These hamper the way the individual thinks and acts, fueling personal rejection. 73
Schizophrenia The literal translation is “split mind” which refers to a split from reality. A group of severe disorders characterized by the following: 1. Disorganized and delusional thinking. 2. Disturbed perceptions. 3. Inappropriate emotions and actions. 74
Types Paranoid-panic and hallucinations Catatonic –stupors, physical immobility Disorganized –speech & thought incoherent; loose touch with reality Undifferentiated –does not fit other categories Residual –symptoms disappear
Symptoms of Schizophrenia Positive symptoms: the presence of inappropriate behaviors (hallucinations, disorganized or delusional talking) Negative symptoms: the absence of appropriate behaviors (expressionless faces, rigid bodies) 76
Disturbed Perceptions A schizophrenic person may perceive things that are not there (hallucinations). Frequently such hallucinations are auditory and lesser visual, somatosensory, olfactory, or gustatory. L. Berthold, Untitled. The Prinzhorn Collection, University of Heidelberg Photos of paintings by Krannert Museum, University of Illinois at Urbana-Champaign August Natter, Witches Head. The Prinzhorn Collection, University of Heidelberg 77
Inappropriate Emotions & Actions A schizophrenic person may laugh at the news of someone dying or show no emotion at all (flat affect). Patients with schizophrenia may continually rub an arm, rock a chair, or remain motionless for hours (catatonia). 78
Onset and Development of Schizophrenia Nearly 1 in a 100 suffer from schizophrenia, and throughout the world over 24 million people suffer from this disease (WHO, 2002). Schizophrenia strikes young people as they mature into adults. It affects men and women equally, but men suffer from it more severely than women. 79
Chronic and Acute Schizophrenia When schizophrenia is slow to develop (chronic/process) recovery is doubtful. Such schizophrenics usually display negative symptoms. When schizophrenia rapidly develops (acute/reactive) recovery is better. Such schizophrenics usually show positive symptoms. 80
Understanding Schizophrenia is a disease of the brain exhibited by the symptoms of the mind. Brain Abnormalities Dopamine Overactivity: Researchers found that schizophrenic patients express higher levels of dopamine D 4 receptors in the brain. 81
Abnormal Brain Activity Brain scans show abnormal activity in the frontal cortex, thalamus, and amygdala of schizophrenic patients. Paul Thompson and Arthur W. Toga, UCLA Laboratory of Neuro Imaging and Judith L. Rapport, National Institute of Mental Health 82
Genetic Factors The likelihood of an individual suffering from schizophrenia is 50% if their identical twin has the disease (Gottesman, 2001). 0 10 20 30 40 50 Identical Both parents Fraternal One parent Sibling Nephew or niece Unrelated 83
Personality Disorders Personality disorders are characterized by inflexible and enduring behavior patterns that impair social functioning. They are usually without anxiety, depression, or delusions. 84
Personality Disorder Activity
Narcissistic Personality
Antisocial Personality Disorder A disorder in which the person (usually men) exhibits a lack of conscience for wrongdoing, even toward friends and family members. Formerly, this person was called a sociopath or psychopath. 88
SOCIOPATHIC PERSONALITY DISORDER 1. Pathological lying, can often pass a lie detector test, as lying is part of the sociopath's innate makeup 2. Shallow emotions, exhibits outward charm but holds inward scorn for others. 3. Overblown ego (total self-centeredness)and sense of entitlement, feelings that whatever they want is their right to have regardless of harm done to others to obtain it 4. Feel their behavior is justified
SOCIOPATHIC PERSONALITY DISORDER 5. Desire to control and manipulate others, sees others more as targets to be victimized than as people 6. Vindictive when thwarted 7. Keenly aware of the weaknesses of others and will exploit those weaknesses to their own advantage, loves to con others for pleasure or for profit 8. Versatile and chameleon-like, changes image and life story as needed to attain immediate goals 9. Lack of conscience, no sense of remorse, guilt, or regret"
Borderline Personality Disorder Borderline personality disorder (BPD) is an emotional disorder that causes emotional instability, leading to stress and other problems. People with BPD have a distorted image of themselves and often feel worthless and fundamentally flawed. They will have outbursts of anger, impulsivity and frequent mood swings. Many people with. B PD get better with treatment and can live happy, peaceful lives. For More information
Understanding Antisocial Personality Disorder Like mood disorders and schizophrenia, antisocial personality disorder has biological and psychological reasons. Youngsters, before committing a crime, respond with lower levels of stress hormones than others do at their age. 92
Understanding Antisocial Personality Disorder PET scans of 41 murderers revealed reduced activity in the frontal lobes. In a follow-up study, repeat offenders had 11% less frontal lobe activity (Raine et al. , 1999; 2000). Courtesy of Adrian Raine, University of Southern California Normal Murderer 93
