Psychiatric symptomatology in borderline and other personality disorders: dissociation and fragmentation as mediators.

This study considered the role of dissociation and personality fragmentation as psychological factors that might distinguish borderline and personality disorder (BPD) patients, and that might explain why BPD patients have higher levels of other psychiatric symptomatology than those with other personality disorders. Two groups of personality-disordered patients (personality disorders including BPD; personality disorders other than BPD) completed measures of dissociation, personality fragmentation, and psychiatric disturbance. The BPD group had higher levels of a number of aspects of psychiatric symptomatology. Those differences were mediated by aspects of dissociation. Personality fragmentation differentiated the two groups but was not related to the higher levels of other aspects of psychiatric disturbance. Treating the syndrome of BPD may depend on addressing both dissociation and personality fragmentation. In contrast, reducing the level of comorbid psychiatric disturbance in BPD is likely to be more strongly dependent on reducing levels of different aspects of dissociation. Psychotherapeutic techniques and targets for achieving such change are discussed.

Dissociated disorders of speaking and writing in aphasia.

Of 500 left brain-damaged patients with educational level above elementary school investigated with a standard quantitative battery for dissociation between oral and written expression, speech was found to be selectively impaired in seven (three with "pure anarthria," two with anarthria in the context of Broca's aphasia, and two with fluent aphasia with remarkable sparing of writing), and writing in another seven (two with "pure" agraphia, two with "agraphia with mild alexia," and three with "agraphia with mild fluent aphasia.") The nature of three conditions (pure anarthria, fluent aphasia with sparing of writing, and pure agraphia) is discussed, with evidence of a selective association between pure agraphia and lesions of the upper left parietal lobule.

Posttraumatic stress disorder, dissociation, and trauma exposure in depressed and nondepressed veterans.

Increasing evidence indicates that exposure to traumatic events predisposes individuals to depressive symptoms as well as to emotional and psychophysiological symptoms covered under the diagnostic criteria of posttraumatic stress disorder (PTSD). Trauma exposure history and PTSD symptoms would, therefore, be expected to be more common in a depressed population than in a nondepressed group. To examine the association between trauma exposure (trauma load), dissociation, and depression, we administered clinical interviews and an assessment package derived from existing instruments (including the Dissociative Experiences Scale; DES) to 101 veteran patients with histories of clinically significant depression and a comparison group of 49 medical patients with no history of depression. The depression group had experienced significantly higher numbers of traumatic incidents, had higher average DES scores, and more frequently met diagnostic criteria for PTSD. The findings support the argument for a causal or predisposing effect of trauma in the expression of clinically significant depression.
