Startle Modulation in Children at Risk for Anxiety Disorders and/or Alcoholism

Year: 1997

Type: article

Abstract: OBJECTIVE: To examine the startle reflex as a possible vulnerability marker among offspring of parents with anxiety disorders and/or alcoholism. METHOD: The subjects were 66 male and female offspring (aged 10 to 17 years) of proband who participated in a family study of comorbidity of alcoholism and anxiety disorders. Testing consisted of examining the startle reflex and its modulation by prepulse stimuli (prepulse facilitation and prepulse inhibition). RESULTS: Different components of the startle discriminated among children of parents with anxiety disorders, children of alcoholics, and children of normal controls. Specifically startle magnitude was elevated in children with a parental history of an anxiety disorder, whereas startle habituation and prepulse inhibition were impaired in children with a parental history of alcoholism. CONCLUSION: These findings suggest that individual differences in the startle reflex may serve as a vulnerability marker for the development of anxiety disorders and alcohol problems.
