title: [The delayed word recall task using ADAS-Jcog word booklet effectively divides patients with mild cognitive impairment from normal elderly people].
abstract: OBJECTIVE
  A new screening test for detecting mild cognitive impairment (MCI) with higher sensitivity that can easily be administered at the bedside is necessary. In this study, we proposed the delayed recall task using the word booklet of Alzheimer's Disease Assessment Scale-cognitive component-Japanese version (ADAS-Jcog) and compared the score of the task in patients with MCI with that of cognitive normal elderly (NE) and patients with AD.
  
  
  METHODS
  Thirty six patients with MCI, 13 very mild AD, 104 mild AD, 13 moderate AD, and age- and education-matched 19 NE, recruited from the memory clinic of Nagoya University Hospital, were evaluated by the ADAS-Jcog word recall task which consisted of immediate recall (IR), a classical method on ADAS-Jcog, and delayed recall (DR) that has been newly introduced.
  
  
  RESULTS
  Compared with controls, patients with MCI were significantly impaired on both IR and DR. On the other hand, DR is more sensitive than IR for distinguishing MCI from NE. The highest sensitivity (94.4%) and specificity (68.4%) were achieved when the results of IR were combined with those of DR.
  
  
  CONCLUSIONS
  The result suggests that the delayed word recall task using the word booklet of ADAS-Jcog may be a useful tool as a screening method for the detection of MCI.
