Twenty-seven veteran subjects with chronic posttraumatic stress disorder (PTSD) were evaluated for dissociative disorders. Ten subjects met criteria for one or more dissociative disorders, and 17 subjects did not meet dissociative disorder criteria. Neurocognitive profiles of the two groups differed in several areas, with veterans meeting diagnostic(More)
Recent findings using volumetric MRI techniques have revealed that patients with combat-related and noncombat-related posttraumatic stress disorder (PTSD) have reductions in right hippocampal volume. Twenty-one veterans with PTSD and eight age-matched control veterans were studied using proton magnetic resonance spectroscopy to test the hypothesis that the(More)
OBJECTIVE This study was carried out to compare the efficacy of lithium carbonate with that of valproate in acute mania and to determine whether pretreatment clinical characteristics, such as the presence of a mixed affective state, might predict a differential response to the two drugs. METHOD Twenty-seven patients meeting DSM-III-R criteria for acute(More)
The authors aim to delineate cognitive dysfunction associated with posttraumatic stress disorder (PTSD) by evaluating a well-defined cohort of former World War II prisoners of war (POWs) with documented trauma and minimal comorbidities. The authors studied a cross-sectional assessment of neuropsychological performance in former POWs with PTSD, PTSD with(More)
A 48-year-old combat veteran sustained a right frontal cerebral infarct at the age of 45 years. The patient's family reports that prior to the infarct he had a preoccupation with memories of combat, as well as nightmares, avoidance of reminders, and multiple arousal symptoms. Since his recovery from the infarct, the patient and his family continue to relate(More)
The neural interface between sensory perception and memory is a central issue in neuroscience, particularly initial memory organization following perceptual analyses. We used functional magnetic resonance imaging to identify anatomic regions extracting initial auditory semantic memory information related to environmental sounds. Two distinct anatomic foci(More)
The current study used a paired stimulus paradigm to investigate the P1 midlatency auditory evoked potential in Vietnam combat veterans with posttraumatic stress disorder (PTSD) and three comparison groups: alcohol dependents, combat-exposed normals, and combat-unexposed normals. Compared to each comparison group, PTSD subjects exhibited significantly(More)
Using the event-related potential P3a component as a marker, the authors tested the efficacy of repetitive transcranial magnetic stimulation (rTMS) for reducing hyperarousability to specific threat stimuli in one Vietnam veteran with chronic posttraumatic stress disorder (PTSD), who exhibited an exaggerated P3a response to combat-related pictures. Twenty(More)
To examine the relationship of alcohol craving to symptoms of posttraumatic stress disorder (PTSD), 129 male veterans with chronic PTSD were asked to complete the Obsessive Compulsive Drinking Scale (OCDS), the Mississippi Scale for combat-related PTSD symptoms, and other instruments to assess general psychopathology and lifetime alcohol and substance use.(More)
Previous studies have reported associations between apolipoprotein E (APOE) genotype, cognitive function, and psychopathology in psychiatric populations. The authors investigated the associations between APOE allele status, memory function, and posttraumatic stress disorder (PTSD) symptom severity in PTSD subjects. Presence of the APOE 2 allele was(More)
