创伤后应激障碍(PTSD)是根据特征来定义的
英文摘要
Posttraumatic Stress Disorder (PTSD) is defined by characteristic
symptoms that develop following exposure to a distressing event that
involves actual or threatened death or serious injury, or a threat to the
physical integrity of self or others (DSM-IV; American Psychiatric
Association; 1994). Included in the symptoms of PTSD are disturbances in
attention, such as increased arousal, difficulty concentrating,
hypervigilance, exaggerated startle response, and heightened
physiological reactivity to cues that symbolize or resemble the event.
Despite the high prevalence and morbidity of PTSD (Browne & Finkelhor,
1986), comparatively little research has been conducted to advance the
understanding of the neurocognitive aspects of this disorder. As pointed
out by Charney, et al. (1994), the dearth of neurocognitive research on
PTSD contrasts sharply with the large body of investigations of the
behavioral, biochemical, and neurophysiological effects of stress in
laboratory animals. These animal studies support the notion that neural
mechanisms and neurochemical alterations contribute to the etiology
and/or the persistence of symptoms associated with PTSD. In this regard,
PTSD provides a unique and valuable model of the protracted effects of
a traumatic event on human neurobiology and cognition. Based on
theoretical issues pertaining to the neurobiological and behavioral
symptoms of PTSD, and the neurobiology of attention, the present study
is proposed to investigate the neurocognitive aspects of attention in
PTSD using both neuropsychological and electrophysiological measures. The
subjects will include a sample of Vietnam combat veterans with PTSD,
Vietnam combat veterans without PTSD, and civilian controls. Event-
related potentials will be obtained using a continuous performance test
paradigm under conditions of sustained and focused attention.
Neuropsychological measures of attention, memory, and executive functions
also will be obtained. The behavioral and electrophysiological measures
will provide information about the possible role of disturbances in
anterior and posterior attentional systems in the development and
maintenance of PTSD symptomatology.
