Long-Term Consequences of Violence Against Children
By KAREN HOPENWASSER, MD
Dissociative disorders, diagnosed as much as nine times more frequently in women than men, are poorly under- stood. The mosaic symptomatology often leads to misdiagnosis or incom- plete assessment. Despite substantial research indicating the probable etiol- ogy as severe childhood abuse, many clinicians do not recognize the rela- tionship between violence and dissoci- ation. An emerging body of research indicates that post-traumatic memory can be distinguished neurobiologically from other forms of memory. While clinical research has given us tools for evaluating dissociative symptoms, neurobiological research is clarifying the relationship between brain devel- opment in children and adult dissocia- tive symptoms. Once the diagnosis is made, many patients report feeling understood for the first time in their lives. This allows for stronger thera- peutic alliances and the use of com- plex treatment techniques to manage pain and increase a sense of safety.
Everyday physicians examine women who have experienced violence as an ordinary occurrence. The awareness that they have been physically beaten and/or sexually abused is silenced in some women by unbearable shame, while for others, the context of violence within the family camouflages their awareness altogether. As children these women used methods of coping that allowed them to manage the pain, maintain emotional connec- tions, and survive into adulthood, albeit with multiple physical and psychological problems. Few physicians have been trained to recognize the long-term conse- quences of early childhood abuse and Dr. Hopenwasser is a clinical assistant professor of psychiatry at Cornell University Medical College and is in practice in New York City.
dissociative disorders, in particular. While the dissociative disorders are weighted with great controversy, this controversy has propelled much-needed research and scientific interest.
The concept of dissociation put forth within the medical community dates back to the late 19th century with the work of Jean-Martin Charcot and Pierre Janet.1 These Salpêtrière physicians had a major influence on Sigmund Freud, who more fully developed the concept of hysteria.2 As psychoanalytic thinking moved from a trauma theory of dissocia- tion to a seduction theory of hysteria, interest in dissociation faded. Although clinicians recognized the phenomenon of “battle fatigue”3 in soldiers during both World Wars, a renewed interest in disso- ciation did not emerge until the late 20th century. Currently, dissociation is recog- nized as a neurophysiological phenome- non that develops in response to envi- ronmental influences and manifests itself in distinct physical and psychological symptoms. Recent research on the neu- robiology of post-traumatic stress disor- der (PTSD) and dissociation4-8 has sup- ported the distinct categorization of dissociative disorders and chronic post- traumatic states. We are becoming increasingly aware that extreme stress, particularly in the form of interpersonal mistreatment, has a profound psycho- physiological impact on the developing child. As we understand more about these consequences, we need to reevaluate some fundamental theories about the structure of the mind, the phenomenology of psychiatric diagnosis, and the impact of environment on brain development after birth.
Dissociation, though, remains an elu- sive concept. Frank Putnam defines it as:
a process that produces a discernible alteration in a person’s thoughts, feel- ings, or actions so that for a period of time certain information is not associated or integrated with other information as it normally or logically would be.9
Bessel van der Kolk, et al subdivide dissociation into three categories: primary, secondary, and tertiary.10 Primary refers to sensory and emotional elements dur- ing a traumatic experience that may not be integrated into memory. Secondary refers to the separation of the experienc- ing and observing self, such as the feeling of floating above oneself and observing from a distance. Tertiary refers to the development of distinct identity states, characterized by particular thoughts, feel- ings, and behaviors. This tertiary form— the dissociative disorders—is the main subject of this paper.
Dissociation will be seen in primary care practice as a symptom of other major psychiatric illness, such as major depressive disorder, bipolar disorders, and substance abuse or withdrawal; as a psychological defense; as a psychiatric ill- ness; and, at times, as a nonpathological experience, including its manifestation in certain non-Western rituals. It will also be seen in a variety of medical condi- tions, such as toxic reactions to chemi- cals, medication reactions, and metabolic disturbances. As a symptom of illness, there is no evidence of a sex difference in prevalence. As a Diagnostic and Statistical Manual (DSM-IV) diagnostic category, however, dissociative identity disorder (DID), formerly multiple personality dis- order, is diagnosed three to nine times more often in women.9,11,12
The dissociative disorders masquerade as a variety of illnesses and somatic disor- ders. A 1991 literature review found an average of seven years between a patient’s entry into treatment and a diagnosis of DID, and that each patient accumulated an average of three to four different diag- noses along the way. The author con- cluded that “clinicians’ general lack of familiarity, . . . skepticism, and low indices of suspicion play important roles in their failure to make the diagnosis in a timely manner.”13 The development of such research-based instruments as the Structured Clinical Interview for Dissociative Disorders,14 the Dissociative Disorders Interview Schedule,12 and the Dissociative Experiences Scale15,16 helps clinicians to make the diagnosis more quickly.
With increased recognition of dissocia- tive disorders, clinicians find that patients feel better understood, sometimes for the first time in their lives. This enhances the sense of trust vital to the therapeutic relationship and increases the sense of safety essential for healing.
Despite some methodological limita- tions, studies on long-term outcome indicate that symptoms and the cost of treatment are both reduced when patients are correctly diagnosed with DID.17,18 Ellason and Ross looked at 54 inpatients with DID over two years and found that with treatment, both Dissociative Expe- riences Scale and Dissociative Disorders Interview Scale scores decreased signifi- cantly, and other symptoms improved.17 The purpose of this review is to help clinicians understand the dissociative disorders in both individual and larger social contexts. The relationship between dissociation as a psychological defense and as a psychiatric illness affords us insight into what can be called a post- Cartesian neurophilosophy of mind/ body unity.19,20 This shift from dualism, the separation of physical and mental, to an appreciation of the material compo- nents of consciousness, helps us to understand dissociative disorders. The nexus of symptom presentation will begin to make sense as we understand the neurophysiology of consciousness and the developmental integration of physical and psychological self.
Relationship Between Dissociation and Violence The dissociative disorders are:
a psychobiological response to a relatively specific set of experiences occurring within a circumscribed developmental window . . . the most compelling and clinically useful model [of the genesis of DID] is based on evidence that repeated childhood trauma enhances normative dissocia- tive capacities, which in turn provide the basis for the creation and elabora- tion of alter personality states over time.21
Repeated childhood trauma can occur within the context of such large scale social violence as the holocaust or war, or within the individual family. The overwhelming majority of US women who suffer from chronic dissociative disorders were victims of childhood physical, emotional, and/or sexual abuse starting between the ages of 2 and 12 years old.22-25 This abuse includes the repetitive exposure to violence against a parent or sibling as well as that experi- enced directly.
A recent epidemiological study in Ontario, Canada of nearly 10,000 resi- dents age 15 and older found that 31.2% of men and 21.1% of women reported a history of childhood physical abuse. Childhood sexual abuse was reported by 12.8% of women and 4.3% of men. Severe physical abuse (based on the Child Maltreatment History Self-Report) was reported nearly equally by men and women (about 10%), while nearly three times as many women as men reported severe sexual abuse (11.1% versus 3.9%).26 These findings support the national consensus that domestic violence against children is common, and that severe sexual abuse is more common in girls than boys and has a prevalence of more than 10%.
While not all abused children develop dissociative disorders, studies have shown a high rate of dissociative disorders in women who identify themselves as sur- vivors of sexual abuse.24,27-29 One study of 98 female psychiatric inpatients found that 83% had dissociative symptom scores above what would be considered median for normal adults, and those with a history of childhood sexual abuse had the highest dissociative experience scale scores. In addition, a history of childhood sexual abuse seemed to double the risk of concurrent physical and sexual abuse in adult life.24
Some clinicians have speculated that men with DID are found more often in the criminal justice system than the men- tal health system.21,30 An example can be found in the work of James Gilligan, a forensic psychiatrist, who noted case after case of severe early childhood maltreat- ment among male murderers in prison.31 In a review of records of 11 men and one woman who had committed murder, clinical researchers were able to establish a link between early severe abuse and DID. They were able to rule out malin- gering, while the evidence of early abuse was based upon corroborating informa- tion from family members, neighbors, court and hospital records. Most of the subjects had at least partial amnesia for the abuse.32
Neurobiology of Dissociation
When abused children grow up, they often have fragmented memories of their childhood experience of violence. While physicians are aware that domestic violence is a nationwide “serious public health problem,”33 adults with inconsis- tent recall are often greeted with skepti- cism. A number of studies of “normal” college students and untraumatized children have demonstrated that children are suggestible, and that memory is unreliable.34,35 These studies have been used in a media campaign that has created excessive doubt in the minds of both clinicians and patients.
The encoding of memories of trauma is subject to stress hormone influences that are different from those of nontrau- matic memory. Neurobiological research, as opposed to laboratory cognitive psy- chological research, has demonstrated that intense overstimulation of the amyg- dala (as a result of a terrifying stimulus) interferes with hippocampal function. As a result, registration of sensorimotor per- ception may occur without symbolic or semantic coding.36 The increased firing of hypothlamic-cortical pathways under stress may lead to increased facilitation of long-term memory. This could account for the eidetic (photographic) nature of flashbacks. Overstimulation may also lead to decreased sensitivity of receptors, leading to decreased registration, consoli- dation, and integration of memory. This accounts for both the “black holes”37 of dissociation as well as errors of recall.
In a study looking at brain activity during flashbacks, positron emission tomography showed increased activity in right limbic, paralimbic areas and visual cortex, while activity was remarkably decreased in left inferior frontal (Broca’s area) and medial temporal cortex, the brain areas necessary for one to find words to describe these experiences.38 In
While research is clarifying the mecha- nisms of PTSD, much less is understood specifically about the neurophysiology of dissociation. The thalamus plays a crucial role in dissociative states, serving as a sensory gate to modulate information between brain stem, cortex, amygdala, and hippocampus.41 One current theory of the biological basis of conscious awareness is that it is dependent on oscil- lating connections between the thalamus and cortex.42 The organization of con- sciousness is dependent on integrated corticocortical function. Certain drugs that produce dissociation interfere with cortical integration. Much laboratory research is now focused on various neuro- transmitters, including the excitatory transmitter glutamate and the NMDA (N-methyl-D-aspartate) receptor. There is hope that the study of these transmit- ters and receptors will someday give us insight into the pharmacologic manage- ment of severe dissociative states.41
Clinical Picture of Dissociative Disorders
The DSM-IV divides dissociative disorders into five diagnostic categories: dissociative amnesia, dissociative fugue, dissociative identity disorder, depersonalization disorder, and dissociative disorder not otherwise specified (DDNOS). DDNOS includes many women who were severely abused as children but have not devel- oped distinct “alter” identities. The tran- sition from the old concept of multiple personality disorder to DID represents an attempt at conceptual advancement. Alter identities are not personalities at all, but could be thought of as uninte- grated or partially integrated pathways of neural networks regulated by neurotrans- mitters and neurohormones.40 As chroni- cally traumatized children mature, they may fail to integrate affectively charged memory with cognitive functioning, and as a result, dissociated alter states (or what Putnam calls “discrete behavioral states”)39 may emerge. This accounts for the classic symptom of “lost time” or memory lapses. In other words, DID is a disorder of consciousness and identity integration over time.40 One of the major tasks of psychotherapeutic treatment is the development of an integrated, sub- jective sense of past and present so as to distinguish between then and now.
It is my belief that this failure to dis- tinguish between past and present is probably responsible for some of the range of psychiatric symptoms we see in dissociative patients, such as panic attacks, phobias, cycling mood changes, suicidal depression, paranoia, and even attention deficit type symptoms. The physical manifestation of this failure is seen in flashback states and somatic memory. Both somatic memory and somatic symptoms bring these patients into the primary care physician’s office.
The multitude of symptoms associated with these disorders often leads to confusion about diagnosis. Many symptoms play together to create a unique picture, while individual symptoms overlap with those of other diagnoses: panic disorder, rapid cycling mood disorders, PTSD, and eating disorders.12 There is also a certain amount of co-morbidity, particularly with chemical dependency prob- lems, borderline personality disorder, PTSD, and mood disorders.28,43 Confu- sion between the Axis II diagnosis borderline personality disorder and Axis I diagnosis dissociative disorder is striking. The two can certainly coexist, while at times one is misdiagnosed for the other. Research on borderline personality disorder has shown an impressive correlation with early childhood abuse,44-46 and diagnostic criteria (identity disturbance, poor impulse control, self-mutilation) clearly overlap. One prospective study found that 38.6% of 44 children diagnosed with borderline personality disorder had abuse histories, compared to only 9%
of 100 controls with a range of other diagnoses.45
Failure to recognize or appreciate a history of severe early trauma can hinder understanding of such extreme behaviors as self-mutilation, which is often a pain management technique used in the ser- vice of emotional survival rather than of self-destruction.47 When done in a state of post-traumatic numbness it can be particularly alienating for the helping professional to watch. Both clinician and patient are caught in the eddy of forgetting the function of this behavior.
Dissociative Disorders in Medical Practice
Women with dissociative disorders fre- quently report somatic complaints;12,48-50 the list is lengthy, with headache, body pain, gastrointestinal and gynecological complaints particularly common. Miller found significant variability in visual functioning, with measurable changes in refraction between alter states in two studies comparing DID patients with simulated controls.51,52 Electromyographic studies indicate there may be marked changes in muscle tension as switches among conscious states are made.53 One recent example encountered personally was a woman who developed blisters on her feet wearing shoes that were already broken in and previously quite comfort- able. A switch into another conscious state (sometimes called a part) led to a shift in posture and manner of walking.
Fluctuations in sensitivity to medica- tions and differential expression of allergic reactions, which can be problematic for the physician prescribing medication, have been found. Clinicians should not assume the patient is misleading if she gives a history of erratic reactions to medication or is confused about whether she has had allergic reactions. In the presence of a history of early trauma, this may be indicative of dissociative state changes.
Both electroencephalographic and thyroid studies can be inconsistent.54 In a prospective, longitudinal study of girls age 8 to 15 years, 14 sexually abused girls were compared with 13 control subjects. The sexually abused girls had twice the frequency of positive plasma antinuclear antibody titers when compared with matched controls, suggesting the possi- bility of alteration in immune function.55

It is a common clinical observation that the patient with severe dissociation seems different from visit to visit. The emotional tenor, quality of voice, body posture, and affect state may change markedly.9,12,21 The patient may well not report awareness of any difference, unless asked directly: Do you have clothing in your closet you don’t remember buying? Does your handwriting change dramati- cally? Do people seem to know you that you do not recall meeting? A rather sub- tle but serious problem is the change in cognitive ability across altered states.56
A highly educated, intellectually capable patient may on a specific occasion not understand directions for further medical treatment and use of medication, and she may not acknowledge it because she is either ashamed or too confused to
say that she does not understand. Cogni- tive changes will alter the relationship between doctor and patient. It can be bewildering to find that the trusting relationship one had developed with a patient is ruptured inexplicably.
Women severely abused as children frequently develop chemical dependency problems.57 One study found that 73% of 55 women being treated for chemical dependency in an inpatient facility had been victims of sexual or physical assault, while those with concurrent PTSD were more likely to have been victims of childhood sexual abuse.58
The Gap Between PTSD and Dissociative Disorders
Most clinicians have treated women victims of violence. PTSD syndromes are common following rape, battering, random crime, and accidents.59,60 Disso- ciation during a traumatic event increases the likelihood of ongoing post-traumatic symptoms.10 This observation has led to the development of the Peritraumatic Dissociative Experiences Questionnaire (PDEQ),61 an instrument that has been used primarily to predict PTSD follow- ing natural disasters. While some trau- matized children develop chronic PTSD and others develop clear DID, there is a vast overlap of symptoms, and probably a majority do not strictly meet the crite- ria for either. Some have suggested com- plex post-traumatic stress disorder62 or disorders of extreme stress63 as diagnoses
for adults who were victims of repeated violence in childhood. These are not yet DSM-IV diagnoses, although the criteria were used during some of the PTSD clinical field trials. These proposed diag- noses take into consideration that pro- longed, repeated trauma in childhood (what Lenore Terr has called Type II trauma)64 disrupts subsequent matura- tional processes and leads to a plethora of symptoms in adult life,65 including failure to self-regulate affect, inability to comfort oneself, impaired attachment (both clinging and fear of intimacy), impaired interpersonal functioning, and mistrustful attitude toward the world.
Use of a diagnosis like disorders of extreme stress would allow us to identify a group of patients who are otherwise misdiagnosed and, consequently, some- times treated inappropriately. It would facilitate a view of the patient as a whole person with a disorder of adaptation, rather than fragmented diagnoses to match the fragmented sense of self.
No controlled studies have addressed the treatment of DID. Perhaps the greatest benefit of the controversy around DID has been the development of treatment guidelines. The International Society for the Study of Dissociation released Guidelines for Treating Dissociative Identity Disorder in Adults in May 1994. Revised in 1997 based on the available clinical and research literature, the guide- lines cover diagnostic procedures, treat- ment planning, and an outline for psychotherapy.66 While there are a vari- ety of treatment approaches, the many clinicians with extensive experience seem to agree that an emphasis on pain man- agement and creation of a sense of safety are necessary regardless of approach.67,68 Building the trust essential for a sense of safety starts with clearly defined bound- aries within the therapeutic relationship.69
Because symptoms are broad and mul- tisystem, an informal treatment team— psychotherapist or psychiatrist, primary care physician and/or gynecologist, and adjunctive social supports—is most productive. Someone who is chemically dependent cannot learn to manage intense affect and integrate this with cognitive function, so the use of 12-step programs
is essential to maintain sobriety. While numerous inpatient programs around the country treat adults with the dual diag- nosis of chemical dependency and disso- ciative problems, the majority of treat- ment occurs in an outpatient setting. Even severe symptoms can be managed on an outpatient basis with pharmaco- logical agents, within the context of psy- chotherapeutic support. Antidepressants relieve some depressive symptoms, though alter switching may create the impression that medication has stopped working.70 Flashbacks can often be man- aged with the long-acting benzodiazapine clonazapam. Anecdotal reports indicate that the alpha adrenergic agonists cloni- dine and guanfacine diminish flashbacks, while case reports have shown the efficacy of propanolol.39 Because propanolol can have substantial side effects and drug- drug interactions, I have tried the beta blocker pindolol, also useful in treating resistant depression, with some success. Carbamazepine, valproic acid, and low- dose new generation neuroleptics have also been helpful. As mentioned above, neurobiological research on dissociation suggests a theoretical role for anti-gluta- mate drugs, yet to be developed.
Psychotherapeutic treatment requires flexibility and versatility. Cognitive restructuring, the modification of long- held beliefs,71 must be done within a care- ful exploratory context. This is usually facilitated through the use of such adjunc- tive therapeutic tools as journal writing, art work, poetry, yoga, meditation, and sometimes body work. In addition to traditional individual and group psycho- therapy, many adult victims of child- hood abuse benefit from nonverbal treatment approaches, such as art and movement therapy.72
How much one has to remember in order to heal is a matter of debate, but it appears that one must remember enough to validate one’s experience and to mourn what was lost by or stolen from the trau- matized child.67,68 Speaking the unspeak- able and having others bear witness to it has allowed many women to move on
in their lives. The process is exquisitely painful, and we have few tools to amelio- rate that pain. I approach dissociative symptoms as a form of memory. Treat- ment needs to support the integration of

these memories as long as they persist, especially since dissociation seems to increase the risk of revictimization, described by Kluft as a “sitting duck syndrome.”73 When dissociation dimin- ishes and no longer interferes with func- tioning, then remembering is determined by individual strengths and other subjec- tive traits. Many women find that spiri- tual connection is the only way to hold and tolerate their memories of utter helplessness and despair.
One very new therapeutic tool for diminishing fear, enhancing safety, and decreasing pain is eye movement desensi- tization and reprocessing (EMDR).74 Originally developed to treat PTSD, it can be incorporated into the overall treatment of dissociative disorders.75,76 Clinical evidence indicates that EMDR allows the patient to downregulate the intensity of affect and process traumatic memories in clusters, rather than indi- vidually. It also allows for the processing of somatic memory in the absence of visual images. EMDR is not a hypnotic technique and does not involve sugges- tion. In the course of an EMDR session, the brain is stimulated through alternating left and right perception either through eye movement, auditory or tactile stimu- lation. Prior to the eye movements, the patient is encouraged to generate an authentic, positive cognition, even if it is difficult to believe in the thought. The alternating stimulation seems to allow for the rapid integration of cognitive and emotional information. While research has not yet explained the mechanism or efficacy of EMDR, “the absence of theory or a conceptual foundation is not suffi- cient to dismiss totally the preliminary findings of the technique.”77 In the hands of a skilled and competent thera- pist, EMDR can be an additional useful tool. The use of hypnosis in treatment and the risks of suggestibility have generated considerable controversy.
In response to concerns about pseudo- memories, the American Society of Clinical Hypnosis released a 1995 task force report concluding that memories may be recovered later in life, that hyp- nosis may facilitate recovery of memo- ries, and that pseudo-memories may occur in and out of therapy, with or without hypnosis.78 Dissociation is a
