title: Abbreviated Mental Test (AMT) in the elderly: shortcoming of an adapted AMT in Zimbabwe.
abstract: OBJECTIVE
  To measure the abbreviated mental test (AMT)-and to determine factors which might influence this in a group of Zimbabwean elders.
  
  
  METHODS
  Community based cross sectional survey.
  
  
  METHODS
  Randomly selected households within randomly selected villages and two high-density urban areas in north eastern Zimbabwe.
  
  
  METHODS
  278 subjects aged 60 to 92 years (124 male, 154 female).
  
  
  METHODS
  A questionnaire, including the AMT, was administered, at home, by trained research nurses.
  
  
  METHODS
  AMT-literacy rates, visual acuity, social and demographic information.
  
  
  RESULTS
  128 (46pc) scored less than seven, a level normally associated with significant mental impairment. Only one subject was actually disoriented in time and place. Multiple regression analysis confirmed that increasing age, female sex, rural evidence, lack of formal education, reduced visual acquity and not currently living with a spouse were all independent factors associated with low AMT score.
  
  
  CONCLUSIONS
  It was apparent that the AMT was not a valid tool for screening for confusion in Zimbabwean elderly, since the prevalence of senile-dementia is increasing in the developing world. It is important to develop a screening test for use in Zimbabwe which is sensitive but is independent of these confounding variables.
