Dissociative and Somatoform Disorders B E H Chapter 7 A V I O Dissociative and R Somatoform Disorders D I S O R Sheila K. Grant, Ph.D. D E R S B E Dissociative Disorders H A Dissociative disorder - A disorder characterized by V disruption, or dissociation, of identity, memory, or I consciousness. O R The major dissociative disorders include dissociative identity disorder, dissociative amnesia, D dissociative fugue, and depersonalization I disorder. S O In each case, there is a disruption or dissociation R (“splitting off ”) of the functions of identity, memory, or D consciousness that normally make us whole. E R S B Overview of Dissociative Disorders E H A V I O R D I S O R D E R S 1 B E Dissociative Disorders H A Dissociative identity disorder - A dissociative V disorder in which a person has two or more distinct, or I alter, personalities. O R In dissociative identity disorder, two or more personalities—each with well-defined traits and D memories—“occupy” one person. I S In the film, The Three Faces of Eve , Eve White is a O timid housewife who harbors two other personalities: Eve R Black, a sexually provocative, antisocial personality, and D Jane, a balanced, developing personality who could E balance her sexual needs with the demands of social R acceptability.

S B E Features H A In some cases, the host (main) personality is unaware of V the existence of the other identities, whereas the other I identities are aware of the existence of the host. O R In other cases, the different personalities are completely unaware of one another. D I Sometimes two personalities vie for control of the S person. O R D E R S 3 B E Controversies H A Although multiple personality is generally considered V rare, the very existence of the disorder continues to I arouse debate. O R Many professionals express profound doubts about the diagnosis. D I Only a handful of cases worldwide were reported from S 1920 to 1970, but since then the number of reported O cases has skyrocketed into the thousands. R D E R S B E H A V I O R D I S O R D E R S B E Dissociative Amnesia H A Amnesia derives from the Greek roots a-, meaning “not,” V and mnasthai, meaning “to remember.” I O Dissociative amnesia - A dissociative disorder in R which a person experiences memory loss without any identifiable organic cause. D I Unlike some progressive forms of memory impairment, S the memory loss in dissociative amnesia is reversible, O although it may last for days, weeks, or even years. R D E R S 4 B “Jane Doe.” E H A This woman, called “Jane V Doe” by rescue workers, was I found wandering in a O Florida park in a dazed R state. She reported she had no memory of her D background or even who she I was. Her parents recognized S her after she appeared on a O national TV program. She R reportedly never regained D her memory. E R S B E Dissociative Amnesia H A Dissociative amnesia is divided into five distinct types of V memory problems: I O 1. Localized amnesia. R 2. Selective amnesia. 3. Generalized amnesia. D 4. Continuous amnesia. I 5. Systematized amnesia. S O R D E R S B E Dissociative Fugue H A Fugue derives from the Latin fugere, meaning “flight.” V The word fugitive has the same origin. I O Fugue is like amnesia “on the run.” R Dissociative fugue - A dissociative disorder in which D one suddenly flees from one’s life situation, travels to a I new location, assumes a new identity, and has amnesia S for personal material. O R D E R S 5 B E Elizabeth Loftus. H A V I O R D I S O R Research by Loftus and others has demonstrated that false memories D of events that never actually occurred can be induced experimentally. E This research calls into question the credibility of reports of R recovered memories. S B E Depersonalization Disorder H A Depersonalization - Feelings of unreality or V detachment from one’s self or one’s body. I O Derealization - A sense of unreality about the outside R world. D Depersonalization disorder - A disorder I characterized by persistent or recurrent episodes of S depersonalization. O R D E R S B E Depersonalization Disorder H A Depersonalization - Feelings of unreality or V detachment from one’s self or one’s body. I O Derealization - A sense of unreality about the outside R world. D Depersonalization disorder - A disorder I characterized by persistent or recurrent episodes of S depersonalization. O R D E R S 6 B E H A V I O R D I S O R D E R S B Culture-Bound Dissociative E H Syndromes A Similarities exist between the Western concept of V dissociative disorder and certain culture-bound I syndromes found in other parts of the world. O R For example, amok is a culture-bound syndrome occurring primarily in southeast Asian and Pacific Island D cultures that describes a trancelike state in which a I person suddenly becomes highly excited and violently S attacks other people or destroys objects. O R People who “run amuck” may later claim to have no D memory of the episode or recall feeling as if they were E acting like a robot. R S B E Psychodynamic Views H A V To psychodynamic theorists, dissociative disorders I involve the massive use of repression, resulting in the O “splitting off” from consciousness of unacceptable R impulses and painful memories. D Dissociative amnesia may serve an adaptive function of I disconnecting or dissociating one’s conscious self from S awareness of traumatic experiences or other sources of O psychological pain or conflict. R D In dissociative amnesia and fugue, the ego protects itself E from anxiety by blotting out disturbing memories or by R dissociating threatening impulses of a sexual or S aggressive nature. 7 B E Social-Cognitive Theory H A V From the standpoint of social-cognitive theory, we I can conceptualize dissociation in the form of dissociative O amnesia or dissociative fugue as a learned response R involving the behavior of psychologically distancing oneself from disturbing memories or emotions. D I Some social-cognitive theorists, such as the late S Nicholas Spanos, believe that dissociative identity O disorder is a form of role-playing acquired through R observational learning and reinforcement. D E R S B E Brain Dysfunction H A Might dissociative behavior be connected with V underlying brain dysfunction? I O Research along these lines is still in its infancy, but R preliminary evidence shows structural differences in brain areas involved in memory and emotion between D patients with dissociative identity disorder (DID) and I healthy controls (Vermetten et al., 2006). S O Another study showed differences in brain metabolic R activity between people with depersonalization disorder D and healthy subjects (Simeon et al.,2000). E R S B E Diathesis–Stress Model H A Despite widespread evidence of severe physical or sexual V abuse in childhood in the great majority of cases of I dissociative identity disorder, very few severely abused O children develop multiple personalities. R Consistent with the diathesis–stress model, certain D personality traits, such as proneness to fantasize, high I ability to be hypnotized, and openness to altered states S of consciousness, may predispose individuals to develop O dissociative experiences in the face of extreme stress, R such as traumatic abuse in childhood. D E R S 8 B Treatment of E H Dissociative Disorders A Dissociative amnesia and fugue are usually fleeting V experiences that end abruptly. I O Episodes of depersonalization can be recurrent and R persistent, and they are most likely to occur when people are undergoing periods of mild anxiety or depression. D I Psychoanalysts seek to help people with dissociative S identity disorder uncover and learn to cope with early O childhood traumas. R D E R S B Diathesis–stress model of E H dissociative identity disorder. A V I O R D I S O R D E R S B E Somatoform Disorders H A V The word somatoform derives from the Greek soma, I meaning “body.” O R Somatoform disorders - A disorder characterized by complaints of physical problems or symptoms that D cannot be explained by physical causes.

    2 Neuroimaging and Dissociative Disorders Angelica Staniloiu1,2,3, Irina Vitcu3 and Hans J. Markowitsch1 1University of Bielefeld, Bielefeld, 2University of Toronto, Toronto, 3Centre for Addiction and Mental Health, Toronto, 1Germany 2,3Canada 1. Introduction Although they were for a while “dissociated” (Spiegel, 2006) from the clinical and scientific arena, dissociative disorders have in the last several years received a renewed interest among several groups of researchers, who embarked on the work of identifying and describing their underlying neural correlates. Dissociative disorders are characterized by transient or chronic failures or disruptions of integration of otherwise integrated functions of consciousness, memory, perception, identity or emotion. The DSM-IV-TR (2000) includes nowadays under the heading of dissociative disorders several diagnostic entities, such as dissociative amnesia and fugue, depersonalization disorder, dissociative identity disorder and dissociative disorder not otherwise specified (such as Ganser syndrome). In contrast to DSM-IV-TR, ICD-10 (1992) also comprises under the category of dissociative (conversion) disorder the entity of conversion disorder (with its various forms), which is in DSM-IV-TR (2000) captured under the heading of somatoform disorders (and probably will remain under the same heading in the upcoming DSM-V). Dissociative disorders had been previously subsumed under the diagnostic construct of hysteria, which had described the occurrence of various constellations of unexplained medical symptoms, without evidence of tissue pathology that can adequately or solely account for the symptom(s). Although not the first one who used the term dissociation or who suggested a connection between (early) traumatic experiences and psychiatric symptomatology (van der Kolk & van der Hart, 1989; Breuer & Freud, 1895), it is Janet (1898, 1907) who claimed dissociation as a mechanism related to traumatic experiences that accounted for the various manifestations of hysteria.

LaRocque Suparna Rajaram Memory Disorders Research Center, VA Boston Healthcare Stony Brook University System, and Boston University School of Medicine Objective: This study aimed to resolve discrepant findings in the literature regarding the effects of massed repetition and a single long study presentation on memory in amnesia. Method: Experiment 1 assessed recognition memory in 9 amnesic patients and 18 controls following presentation of a study list that contained items shown for a single short study presentation, a single long study presentation, and three massed repetitions. In Experiment 2, the same encoding conditions were presented in a blocked rather than intermixed format to all participants from Experiment 1. Results: In Experiment 1, control participants showed benefits associated with both types of extended exposure, and massed repetition was more beneficial than long study presentation, F(2, 34) ϭ 14.03, p Ͻ .001, partial ␩2 ϭ .45. In contrast, amnesic participants failed to show benefits of either type of extended exposure, F Ͻ 1. In Experiment 2, both groups benefited from repetition, but did so in different ways, F(2, 50) ϭ 4.80, p ϭ .012, partial ␩2 ϭ .16. Amnesic patients showed significant and equivalent benefit associated with both types of extended exposure, F(2, 16) ϭ 5.58, p ϭ .015, partial ␩2 ϭ .41, but control participants again benefited more from massed repetition than from long study presentation, F(2, 34) ϭ 23.74, p Ͻ .001, partial ␩2 ϭ .58.

  • The Hippocampus and Dorsolateral Striatum Integrate Distinct Types of Memories Through Time and Space, Respectively
    The Journal of Neuroscience, November 18, 2020 • 40(47):9055–9065 • 9055 Behavioral/Cognitive The Hippocampus and Dorsolateral Striatum Integrate Distinct Types of Memories through Time and Space, Respectively Janina Ferbinteanu Departments of Physiology and Pharmacology, and Neurology, SUNY Downstate Medical Center, Brooklyn, New York 11203 Several decades of research have established that different kinds of memories result from the activity of discrete neural net- works. Studying how these networks process information in experiments that target specific types of mnemonic representa- tions has provided deep insights into memory architecture and its neural underpinnings. However, in natural settings reality confronts organisms with problems that are not neatly compartmentalized. Thus, a critical problem in memory research that still needs to be addressed is how distinct types of memories are ultimately integrated. Here we demonstrate how two mem- ory networks, the hippocampus and dorsolateral striatum, may accomplish such a goal. The hippocampus supports memory for facts and events, collectively known as declarative memory and often studied as spatial memory in rodents. The dorsolat- eral striatum provides the basis for habits that are assessed in stimulus–response types of tasks. Expanding previous findings, the current work revealed that in male Long–Evans rats, the hippocampus and dorsolateral striatum use time and space in distinct and largely complementary ways to integrate spatial and habitual representations. Specifically, the hippocampus sup- ported both types of memories when they were formed in temporal juxtaposition, even if the learning took place in different environments. In contrast, the lateral striatum supported both types of memories if they were formed in the same environ- ment, even at temporally distinct points.
