title: Cognitive impairment in late-life generalized anxiety disorder.
abstract: OBJECTIVE
  This study sought to characterize cognitive functioning in elderly patients with generalized anxiety disorder (GAD), as compared with normal comparison subjects and patients with major depression.
  
  
  METHODS
  The cognitive functioning in GAD (N=19) was assessed with the Mattis Dementia Rating Scale and across specific domains of naming, executive ability, and memory, in comparison with late-life major depressive disorder (MDD; N=68) and versus no psychiatric illness (N=40).
  
  
  RESULTS
  In comparison to healthy normal comparison subjects, anxious subjects were impaired on measures of short-term and delayed memory. Depressed subjects also performed worse than normal comparison subjects on delayed memory, as well as in naming. Anxious subjects did not differ significantly from depressed subjects in any measure of cognitive function.
  
  
  CONCLUSIONS
  In this preliminary study, anxious subjects displayed cognitive impairments in short-term memory; while depressed patients compared to normal comparison subjects showed executive dysfunction and more general cognitive impairments not evident in anxious subjects. Studies of neuropsychological function in elderly anxious subjects may be informative in developing treatment interventions that mitigate cognitive dysfunction and illuminate the course of illness and underlying neural pathways.
