Psychophysiological assessment data, including heart rate (HR), blood pressure, and frontal electromyogram (EMG) responses to mental arithmetic, idiosyncratic audiotape descriptions of motor vehicle accidents (MVAs), and a standard videotape of MVAs, were collected on 105 injured victims of recent MVAs and 54 non-MVA controls. Their data replicated data(More)
This study investigated the effect of traumatic brain injury on the development of posttraumatic stress disorder (PTSD). Subjects were 107 motor vehicle accident survivors including 38 individuals who were diagnosed with posttraumatic stress disorder (PTSD). Neuropsychological testing was administered to all subjects during an initial diagnostic evaluation.(More)
This study sought to replicate past research that has shown differences in physiological responsiveness among survivors of motor vehicle accidents (MVAs) with posttraumatic stress disorder (PTSD) and those survivors who do not develop this disorder. Such physiological differences have been found specifically with heart rate (HR) reactivity. This study also(More)
Twenty-one children and adolescents (age range 8-17, mean 12.7 years) who had been in motor vehicle accidents (MVAs), and 14 non-MVA controls matched for age and gender, underwent a psychophysiological assessment in which heart rate, systolic and diastolic blood pressure, and skin conductance were measured during baseline and two stressor phases: mental(More)
Seventy-eight motor vehicle accident survivors with chronic (greater than 6 months) PTSD, or severe sub-syndromal PTSD, completed a randomized controlled comparison of cognitive behavioral therapy (CBT), supportive psychotherapy (SUPPORT), or a Wait List control condition with two detailed assessments. Scores on the CAPS showed significantly greater(More)
Seven participants who did not meet the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) criteria for posttraumatic stress disorder (PTSD) 1-4 months post- motor vehicle accident (MVA) and developed delayed onset PTSD during a 1-year follow-up interval were compared with 38 MVA controls who did(More)
We studied a 24-year-old man who had reading epilepsy after removal of a left frontal arteriovenous malformation. Lesion analysis by means of a neuroanatomic template placed a 2-cm region of encephalomalacia anterior to the left central sulcus in premotor cortex (Brodmann's area 6). Lexical and nonlexical reading activation tests demonstrated seizures(More)
For 98 victims of recent (1 to 4 months post-accident) motor vehicle accidents who sought medical attention as a result of the accident, we obtained data on the extent of physical injury using blind ratings with the Abbreviated Injury Scale (AIS), as well as victims reports of their perceptions of how much danger they perceived at the time of the accident(More)
The modified or "emotional" Stroop paradigm has been frequently employed in previous evaluations of information processing models of Posttraumatic Stress Disorder (PTSD) and other anxiety disorders. These studies have frequently documented an attentional bias to trauma-specific threatening stimuli in PTSD patients. However, the response of the Stroop(More)
