14.6 The Dissociative Disorders: FRAGMENTATION OF THE SELF

KEY THEME

In the dissociative disorders, disruptions in awareness, memory, and identity interfere with the ability to function in everyday life.

KEY QUESTIONS

Dissociation and Possession A member of the Dongria Kondh tribe in eastern India dances in a trance during a ceremony on top of Niyamgiri mountain, which the community regards as sacred. Such dissociative trance and possession states are common in religions around the world (Krippner, 1994). When dissociative experiences take place within a religious ritual context, they are not considered abnormal. In fact, such experiences may be highly valued (Mulhern, 1991)

Despite the many changes you’ve experienced throughout your lifetime, you have a pretty consistent sense of identity. You’re aware of your surroundings and can easily recall memories from the recent and distant past. In other words, a normal personality is one in which awareness, memory, and personal identity are associated and well-integrated.

In contrast, a dissociative experience is one in which a person’s awareness, memory, and personal identity become separated or divided. While that may sound weird, dissociative experiences are not inherently pathological. Mild dissociative experiences are quite common and completely normal (Dalenberg & others, 2009; Wieland, 2011). For example, you become so absorbed in a book or movie that you lose all track of time. While driving, your author Susan is occasionally so preoccupied with her thoughts—often about her class that day—that when she arrives on campus, she remembers next to nothing about the trip. In each of these cases, you’ve experienced a temporary “break” or “separation” in your memory or awareness—a temporary, mild dissociative experience.

dissociative experience

A break or disruption in consciousness during which awareness, memory, and personal identity become separated or divided.

Clearly, then, dissociative experiences are not necessarily abnormal. But in the dissociative disorders, the dissociative experiences are much more extreme or more frequent and they severely disrupt everyday functioning. Awareness, or recognition of familiar surroundings, may be completely obstructed. Memories of pertinent personal information may be unavailable to consciousness. Identity may be lost, confused, or fragmented (Dell & O’Neil, 2009).

dissociative disorders

A category of psychological disorders in which extreme and frequent disruptions of awareness, memory, and personal identity impair the ability to function.

The category of dissociative disorders consists of two basic disorders: (1) dissociative amnesia, which can occur either with or without dissociative fugue, and (2) dissociative identity disorder, which was previously called multiple personality disorder. Until recently, the dissociative disorders were thought to be extremely rare. How rare? An extensive review conducted in the 1940s uncovered a grand total of 76 reported cases of dissociative disorders since the beginnings of modern medicine in the 1700s (Taylor & Martin, 1944). Although a few more cases were reported during the 1950s and 1960s, the clinical picture changed dramatically in the 1970s when a surge of dissociative disorder diagnoses occurred (Kihlstrom, 2005). Later in this discussion, we’ll explore some of the possible reasons as well as the controversy surrounding the “epidemic” of dissociative disorders that began in the 1970s.

Dissociative Amnesia and Dissociative Fugue: FORGETTING AND WANDERING

Dissociative Fugue: “Who Am I Now?” Just before a new school year, 23-year-old teacher Hannah Upp disappeared. Intensive search efforts produced nothing, but then Hannah was seen at a Manhattan Apple store and, later, at a Starbucks. Hannah was finally rescued when a Staten Island Ferry crew saw her swimming almost a mile from shore—three weeks after she had initially disappeared. Hannah had no memories of the events following her disappearance, and was disturbed by her amnesia and flight. In an interview, she asked, “How do you feel guilty for something you didn’t even know you did? It’s not your fault, but it’s still somehow you. So it’s definitely made me reconsider everything. Who was I before? Who was I then—is that part of me? Who am I now?” (Marx & Didziulis, 2009) Although psychologists don’t understand what causes dissociative amnesia with dissociative fugue, a rare condition, stressful events are often implicated.

Dissociative amnesia refers to the partial or total inability to recall important information that is not due to a medical condition, such as an illness, an injury, or a drug. Usually the person develops amnesia for personal events and information, rather than for general knowledge or skills. That is, the person may not be able to remember his wife’s name but does remember how to read and who Martin Luther King, Jr., was. In most cases, dissociative amnesia is a response to stress, trauma, or an extremely distressing situation, such as combat, marital problems, or physical abuse (McLewin & Muller, 2006).

Some cases of dissociative amnesia involve a condition called dissociative fugue. In amnesia with dissociative fugue, the person outwardly appears completely normal. However, the person is confused about her identity. While in the fugue state, she suddenly and inexplicably travels away from her home, wandering to other cities or even countries. In some cases, people in a fugue state adopt a completely new identity.

As is true with other cases of amnesia, dissociative fugues are thought to be associated with traumatic events or stressful periods. However, it’s unclear as to how a fugue state develops, or why a person experiences a fugue state rather than other sorts of symptoms, such as simple anxiety or depression. Interestingly, when the person “awakens” from the fugue state, she may remember her past history but have amnesia for what occurred during the fugue state (DSM-5, 2013).

Dissociative Identity Disorder: MULTIPLE PERSONALITIES

Among the dissociative disorders, none is more fascinating—or controversial—than dissociative identity disorder, formerly known as multiple personality disorder. Dissociative identity disorder (DID) involves extensive memory disruptions for personal information along with the presence of two or more distinct identities, or “personalities,” within a single person.

dissociative identity disorder (DID)

A dissociative disorder involving extensive memory disruptions along with the presence of two or more distinct identities, or “personalities”; formerly called multiple personality disorder.

Typically, each personality has its own name and is experienced as if it has its own personal history and self-image. These alternate personalities, often called alters or alter egos, may be of widely varying ages and different genders. Alters are not really separate people. Rather, they constitute a “system of mind” (Courtois & Ford, 2009). That is, the alters seem to embody different aspects of the individual’s personality that, for some reason, cannot be integrated into the primary personality. The alternate personalities hold memories, emotions, and motives that are not admissible to the individual’s conscious mind. At different times, different alter egos take control of the person’s experience, thoughts, and behavior. Typically, the primary personality is unaware of the existence of the alternate personalities. However, the alter egos may have knowledge of each other’s existence and share memories (see Kong & others, 2008). Sometimes the experiences of one alter are accessible to another alter but not vice versa.

Symptoms of amnesia and memory problems are reported in virtually all cases of DID. There are frequent gaps in memory for both recent and childhood experiences. Commonly, those with dissociative identity disorder “lose time” and are unable to recall their behavior or whereabouts during specific time periods. In addition to their memory problems, people with DID typically have numerous psychiatric and physical symptoms, along with a chaotic personal history (Cardena & Gleaves, 2007). Symptoms of major depressive disorder, anxiety, posttraumatic stress disorder, substance abuse, sleep disorders, and self-destructive behavior are also very common. Often, the DID patient has been diagnosed with a variety of other psychological disorders before the DID diagnosis is made (Rodewald & others, 2011).

Not all mental health professionals are convinced that dissociative identity disorder is a genuine psychological disorder (Cardena & Gleaves, 2007; Lynn & others, 2006). One reason for skepticism is that reported cases sharply increased in the early 1970s shortly after books, films, and television dramas about multiple personality disorder became popular. As psychologist John Kihlstrom (2005) noted, not only the number of cases but also the number of “alters” showed a dramatic increase. To some psychologists, such findings suggest that DID patients learned “how to behave like a multiple” from media portrayals of sensational cases or by responding to their therapists’ suggestions (Gee & others, 2003; Lynn & others, 2012). People with another mental illness or other vulnerability might be particularly susceptible to such influences (Lynn & others, 2012). And there is research to support this conclusion. Guy Boysen and Alexandra VanBergen reviewed many studies of people with dissociative identity disorder, and concluded that “in terms of key symptoms of the disorder, people taught to simulate DID are largely indistinguishable from people actually diagnosed with DID” (2014).

On the other hand, DID is not the only psychological disorder for which prevalence rates have increased over time. For example, rates of obsessive–compulsive disorder and PTSD have also increased over the past few decades, primarily because mental health professionals have become more aware of these disorders and more likely to screen for symptoms. The dissociative disorders are summarized in TABLE 14.8.

EXPLAINING DISSOCIATIVE IDENTITY DISORDER

Herschel Walker and Dissociative Identity Disorder As a professional football player, Walker (2008) was somewhat of an enigma to his teammates because of his diverse pursuits, which ranged from bobsledding to ballet dancing, and because he often referred to himself in the third person. “Herschel played well today,” he might say. After retiring from football, Walker began suffering from unexplained violent outbursts, blackouts, and memory loss. Since being diagnosed with dissociative identity disorder, Walker has identified a dozen distinct alters, including “The Warrior,” who handled playing football and the pain that went with it, and “The Hero,” who made public appearances. With therapy, Walker is learning to manage his symptoms and hopes to educate the public about this rare disorder.

According to one explanation, dissociative identity disorder represents an extreme form of dissociative coping (Moskowitz & others, 2009). A very high percentage of DID patients report having suffered extreme physical or sexual abuse in childhood—over 90 percent in most surveys (Foote & others, 2006; Sar & others, 2007). According to this explanation, to cope with the trauma, the child “dissociates” himself or herself from it, creating alternate personalities to experience the trauma.

Over time, alternate personalities are created to deal with the memories and emotions associated with intolerably painful experiences. Feelings of anger, rage, fear, and guilt that are too powerful for the child to consciously integrate can be dissociated into these alternate personalities. In effect, dissociation becomes a pathological defense mechanism that the person uses to cope with overwhelming experiences.

Although widely accepted among therapists who work with dissociative identity disorder patients, the dissociative coping theory is difficult to test empirically. One problem is that memories of childhood are notoriously unreliable. Since DID is usually diagnosed in adulthood, it is very difficult, and often impossible, to determine whether the reports of childhood abuse are real or imaginary.

Another problem with the “traumatic memory” explanation of dissociative identity disorder is that just the opposite effect occurs to most trauma victims—they are bothered by recurring and intrusive memories of the traumatic event. For example, in a study by Gail Goodman and her colleagues (2003), more than 80 percent of young adults with a documented history of childhood sexual abuse remembered the abuse. Of those who didn’t report the abuse, reluctance to disclose the abuse and being too young to remember the abuse seemed to be the most likely explanations. Although the scientific debate about the validity of the dissociative disorders is likely to continue for some time, the dissociative disorders are fundamentally different from the last major category of disorders we’ll consider—schizophrenia.

Possible sample answer: With dissociative disorders conscious awareness becomes separated from previous memories, thoughts, and feelings. A person with dissociative identity disorder (DID) claims to have two or more distinct personalities. DID is particularly controversial because it seems to be limited almost exclusively to North America and to people with rich imaginations and a tendency to be suggestible. Skeptics claim that DID is a product of leading statements by therapists. Advocates claim that the distinct body and brain states associated with the different personalities suggest that DID is a real disorder.
