title: Delusions of Japanese patients with Alzheimer's disease.
abstract: BACKGROUND
  Delusions constitute one of the most prominent psychiatric complications in Alzheimer's disease (AD). However, there is little consensus of the prevalence and associated factors for delusions in AD.
  
  
  OBJECTIVE
  To reveal the characteristics of delusions among Japanese patients with AD.
  
  
  METHODS
  112 consecutive patients with AD were recruited over a one year period and administered the Neuropsychiatric Inventory (NPI).
  
  
  RESULTS
  Delusions were present in 53 patients (47.3%). Delusions of theft were the most common type of delusion (75.5% of patients with delusions), followed by misidentification delusions and delusions of suspicion. More hallucination, agitation, and female gender were found in the delusions group.
  
  
  CONCLUSIONS
  The authors found a high frequency of delusions, particularly of delusions of theft and suggested that gender was associated with the expression of delusions in Japanese patients with AD.
