title: [Planning and activities of daily living in Alzheimer's disease and frontotemporal dementia].
abstract: OBJECTIVE
  To study the relationship between the disturbances in activities of daily living and the scores on tests assessing planning activities in frontotemporal dementia (FTD) and Alzheimer's disease (AD).
  
  
  METHODS
  Eleven patients with FTD were compared to 11 patients with AD and 29 healthy controls. Cognitive status, evaluated by the Dementia Rating Scale (DRS) and the Mini Mental State Examination (MMSE) was identical in the two groups of patients. Activities of daily living were assessed by three questionnaires completed by the main caregiver: (1) the Cognitive Difficulties Scale (CDS); (2) the NADL, a composite scale including the Physical self-maintenance scale (ADL) the Instrumental activities of daily living (IADL) the social activities scale, (SADL); (3) the Dysexecutive Questionnaire (DEX) from the Behavioural Assessment of the Dysexecutive Syndrome. Planning abilities were assessed by the tower of London and three tests from the BADS: the key search, the zoo map and the six elements.
  
  
  RESULTS
  No quantitative differences were found between FTD and AD patients in daily living activities disturbances or scores on planning tests. Both were closely related to the global cognitive performance assessed by the DRS or the MMSE but no clear relationship was found between them. The scores on the tower of London were not correlated to those on the tests from the BADS.
  
  
  CONCLUSIONS
  Neither assessment of activities of daily living or scores on the planning tests could differentiate FTD from AD. Planning appears as a multidimensional construct poorly assessed by the usual assessment tools.
