title: Cognitive performance in suicidal depressed elderly: preliminary report.
abstract: OBJECTIVE
  Deficits in executive functions may play an important role in late-life suicide; however the association is understudied. This study examined cognitive function in general and executive functioning specifically in depressed elderly with and without suicidal ideation and attempts.
  
  
  METHODS
  Case-control study.
  
  
  METHODS
  University-affiliated psychiatric hospital.
  
  
  METHODS
  We compared 32 suicidal depressed participants aged 60 and older with 32 non-suicidal depressed participants equated for age, education, and gender.
  
  
  METHODS
  We assessed global cognitive function and executive function with the Dementia Rating Scale (DRS) and the Executive Interview (EXIT25), respectively.
  
  
  RESULTS
  Suicidal and non-suicidal depressed groups were comparable in terms of severity of depression and burden of physical illness. Suicidal participants performed worse on the EXIT25, and on the DRS total scale, as well as on Memory and Attention subscales. The differences were not explained by the presence of dementia, substance use, medication exposure, or brain injury from suicide attempts.
  
  
  CONCLUSIONS
  Poor performance on tests of executive function, attention, and memory is associated with suicidal behavior in late-life depression.
