Anxiety Disorders Phobia Key commonality is physiological: heart rate, breathing, sweating, dry mouth, sense of dread Fear/anxiety phobia generalized anxiety disorder Panic disorder obsessive compulsive disorder PTSD Often phobias are experienced as irrational Simple or specific Classic, typically afraid of a specific object or situation: Spiders, Heights, Etc. Social Major fear his of humiliation and/embarrassment Avoids opportunities that could put them into a position of ridicule: Eating in public, public restrooms, public speaking Agora Fear of being separated from a safe place or person Generalized Anxiety Disorder A nonspecific experience of anxiety, worry This excessive worry often interferes with daily functioning, as individuals suffering GAD typically anticipate disaster, and are overly concerned about everyday matters such as health issues, money, death, family problems, friend problems, relationship problems or work difficulties. Often comorbid with dysthymia Panic Disorder Attack vs Disorder Terror and fear of death, going crazy Often experienced as coming from out of the blue Hyper sensitivity to physiological changes Cognitive tendency to catastrophize those changes OCD Obsessive compulsive disorder is characterized by obsessions and compulsions Obsessions are thoughts the create anxiety The thoughts made be about germs dirt or graphically violent thoughts Compulsions temporarily reduce that anxiety PTSD Trauma defined Acute vs. post Acute occurs within 30 days of trauma, post occurs after Symptoms include avoidance of anything that could remind a person of trauma Flashbacks and nightmares 3
Disorders Physical ailments without physical cause Earliest forms were targeted by Freud (Anna O) Conversion Hypochondriasis Somatization (Briquettes) Pain Disorder Over the course of the 20th century numerous studies convinced medical and clinical researchers that psychological factors, such as stress, worry, and perhaps even unconscious needs, can contribute to bodily illness Sometimes when physicians cannot find a medical cause for a patient s symptoms, he or she may suspect other factors are involved. Patients may malinger, intentionally fake illness to achieve external gain (e.g., financial compensation, military deferment) Patients may be manifesting a factitious disorder - intentionally producing or faking symptoms simply out of a wish to be a patient Known popularly as Munchausen syndrome, people with a factitious disorder often go to extremes to create the appearance of illness Many secretly give themselves medications to produce symptoms Patients often research their supposed ailments and are impressively knowledgeable about medicine Conversion disorder often is hard to distinguish from genuine medical problems It is always possible that a diagnosis of conversion disorder is a mistake and the patient s problem has an undetected medical cause Physicians sometimes rely on oddities in the patient s medical picture to help distinguish the two For example, conversion symptoms may be at odds with the known functioning of the nervous system, as in cases of glove anesthesia People with a somatization pattern experience many long-lasting physical ailments that have little or no organic basis Also known as Briquet s syndrome A sufferer s ailments often include pain symptoms, gastrointestinal symptoms, sexual symptoms, and neurological symptoms Patients usually go from doctor to doctor in search of relief 4
Tx Predominant pain pattern If the primary feature of somatic symptom disorder is pain, the individual is said to have a predominant pain pattern Although the precise prevalence has not been determined, this pattern appears to be fairly common The pattern often develops after an accident or illness that has caused genuine pain The pattern may begin at any age, and more women than men seem to experience it Difficult to treat Controversial: maybe not psychological but we don t have the tech to dx Hypochondriasis tx includes recommendation to Doctors to being open and setting the stage for the next doctor to do the same. Be honest, sincere, and supportive, but don t feed the client s anxieties or demands. Based on the Defense Mechanism Think of your safe place rather than be present Similar to hypnosis Common in childhood (make believe friend) Amnesia (not biological) Fugue Identity Disorder (DID, FKA Multiple Personality Disorder) The key to our identity the sense of who we are and where we fit in our environment is memory In dissociative disorders, one part of the person s memory typically seems to be dissociated, or separated, from the rest There are several kinds of dissociative disorders, including: amnesia identity disorder (multiple personality disorder) Depersonalization-derealization disorder These disorders are often memorably portrayed in books, movies, and television programs People with dissociative amnesia are unable to recall important information, usually of a stressful nature, about their lives The loss of memory is much more extensive than normal forgetting and is not caused by physical factors Often an episode of amnesia is directly triggered by a specific upsetting event 5
amnesia may be: Localized most common type; loss of all memory of events occurring within a limited period Selective loss of memory for some, but not all, events occurring within a period Generalized loss of memory beginning with an event, but extending back in time; may lose sense of identity; may fail to recognize family and friends Continuous forgetting continues into the future; quite rare in cases of dissociative amnesia All forms of the disorder are similar in that the amnesia interferes mostly with a person s memory for personal material Memory for abstract or encyclopedic information usually remains intact Clinicians do not known how common dissociative amnesia is, but many cases seem to begin serious threats to health and safety An extreme version of dissociative amnesia is called dissociative fugue Here persons not only forget their personal identities and details of their past, but also flee to an entirely different location For some, the fugue is brief a matter of hours or days and ends suddenly For others, the fugue is more severe: people may travel far from home, take a new name and establish new relationships, and even a new line of work; some display new personality characteristics A person with dissociative identity disorder (DID, or multiple personality disorder) develops two or more distinct personalities, called subpersonalities, each with a unique set of memories, behaviors, thoughts, and emotions At any given time, one of the subpersonalities dominates the person s functioning Usually one of these subpersonalities called the primary, or host, personality appears more often than the others The transition from one subpersonality to the next ( switching ) is usually sudden and may be dramatic Most cases are first diagnosed in late adolescence or early adulthood Symptoms generally begin in childhood after episodes of abuse Women receive the diagnosis three times as often as men 6
How do subpersonalities interact? The relationship between or among subpersonalities varies from case to case Generally there are three kinds of relationships: Mutually amnesic relationships subpersonalities have no awareness of one another Mutually cognizant patterns each subpersonality is well aware of the rest One-way amnesic relationships most common pattern; some personalities are aware of others, but the awareness is not mutual» Those who are aware ( co-conscious subpersonalities ) are quiet observers How do subpersonalities interact? Investigators used to believe that most cases of the disorder involved two or three subpersonalities Studies now suggest that the average number is much higher 15 for women, 8 for men There have been cases of more than 100! How do subpersonalities differ? Subpersonalities often display dramatically different characteristics, including: Identifying features Subpersonalities may differ in features as basic as age, sex, race, and family history Abilities and preferences Although encyclopedic information is not usually affected by dissociative amnesia, in DID it is often disturbed It is not uncommon for different subpersonalities to have different abilities, including being able to drive, speak a foreign language, or play an instrument How do subpersonalities differ? Subpersonalities often display dramatically different characteristics, including: Physiological responses Researchers have discovered that subpersonalities may have physiological differences, such as differences in autonomic nervous system activity, blood pressure levels, and allergies How common is DID? Traditionally, DID was believed to be rare Some researchers even argue that many or all cases are iatrogenic; that is, unintentionally produced by practitioners These arguments are supported by the fact that many cases of DID first come to attention only after a person is already in treatment» Not true of all cases The psychodynamic view Psychodynamic theorists believe that dissociative disorders are caused by repression, the most basic ego defense mechanism People fight off anxiety by unconsciously preventing painful memories, thoughts, or impulses from reaching awareness 7
The psychodynamic view In this view, dissociative amnesia is a single episode of massive repression DID is thought to result from a lifetime of excessive repression, motivated by very traumatic childhood events The behavioral view Behaviorists believe that dissociation grows from normal memory processes and is a response learned through operant conditioning: Momentary forgetting of trauma leads to a drop in anxiety, which increases the likelihood of future forgetting Like psychodynamic theorists, behaviorists see dissociation as escape behavior Also like psychodynamic theorists, behaviorists rely largely on case histories to support their view of dissociative disorders Moreover, these explanations fail to explain all aspects of these disorders State-dependent learning If people learn something when they are in a particular state of mind, they are likely to remember it best when they are in the same condition This link between state and recall is called statedependent learning This model has been demonstrated with substances and mood and may be linked to arousal levels Self-hypnosis Although hypnosis can help people remember events that occurred and were forgotten years ago, it can also help people forget facts, events, and their personal identity Called hypnotic amnesia, this phenomenon has been demonstrated in research studies with word lists The parallels between hypnotic amnesia and dissociative disorders are striking and have led researchers to conclude that dissociative disorders may be a form of self-hypnosis People with dissociative amnesia often recover on their own Only sometimes do their memory problems linger and require treatment In contrast, people with DID usually require treatment to regain their lost memories and develop an integrated personality Treatment for dissociative amnesia tends to be more successful than treatment for DID How do therapists help people with dissociative amnesia? The leading treatments for these disorders are psychodynamic therapy, hypnotic therapy, and drug therapy Psychodynamic therapists guide patients to search their unconscious and bring forgotten experiences into consciousness In hypnotic therapy, patients are hypnotized and guided to recall forgotten events Sometimes intravenous injections of barbiturates are used to help patients regain lost memories Often called truth serums, the key to the drugs success is their ability to calm people and free their inhibitions 8
How do therapists help individuals with DID? Therapists usually try to help the client by: Recognizing the disorder Once a diagnosis of DID has been made, therapists try to bond with the primary personality and with each of the subpersonalities As bonds are forged, therapists try to educate the patients and help them recognize the nature of the disorder» Some use hypnosis or video as a means of presenting other subpersonalities Many therapists recommend group or family therapy How do therapists help individuals with DID? Therapists usually try to help the client by: Recovering memories To help patients recover missing memories, therapists use many of the approaches applied in other dissociative disorders, including psychodynamic therapy, hypnotherapy, and drug treatment» These techniques tend to work slowly in cases of DID 9
