| Resumen:Traumatic events can have a profound and lasting impact on the emotional, cognitive, behavioral and physiological functioning of an individual. These adverse effects have been described in combat veterans since the Civil War (DaCosta 1871, Bury 1918, Frazer and Wilson 1918, Dobbs and Wilson 1960 Birkhimer et al. 1985, Bleich et al. 1986). Only recently, however, has the distinct trauma-associated syndrome characterized by prominent affective symptoms (dysphoria, irritability, anxiety) and a 'hyperactive' sympathetic nervous system (Horowitz et al. 1980, Brende 1982 ) been called Post-Traumatic Stress Disorder (DSM-III, PTSD). The symptoms of PTSD fall into three clusters; 1) recurring intrusive recollection of the traumatic event such as dreams and 'flashbacks', 2) persistent avoidance of stimuli associated with the trauma or numbing of general responsiveness and 3) persistent symptoms of increased arousal characterized by hypervigilance, increased startle response, sleep difficulties, irritability, anxiety and physiological hyperreactivity. While described originally in combat veterans, a high percentage of rape victims, sexual abuse victims, survivors of natural or manmade disasters, and witnesses to violence also experience symptoms of PTSD (e.g.,Terr 1983, Blanchard et al. 1983, Boehlein et al. 1985, McLeer et al. 1988). The largest group of victims of these traumatic events are children. The present chapter will review childhood PTSD with specific focus on neurobiological sequelae of childhood trauma and present some preliminary evidence of altered functioning of brainstem catecholamine systems in childhood PTSD. In specific, it is hypothesized that the abnormal patterns of catecholamine activity associated with prolonged 'alarm reactions' induced by traumatic events during infancy and childhood can result in altered development of the central nervous system (CNS). Furthermore, it is hypothesized that this altered development includes a 'dysregulated' brainstem which in turn results in a host of signs and symptoms related to abnormal brainstem functioning, including altered cardiovascular regulation, affective lability, behavioral impulsivity, increased anxiety, increased startle response and sleep abnormalities. Finally, early life experience is discussed, in context of childhood trauma, as an 'expresser of genetic predispositions. | |
