title: [Behavioral and psychological symptoms, cognitive impairment and caregiver burden related to Alzheimer's disease patients treated in an outpatient memory clinic].
abstract: OBJECTIVE
  The relationships among behavioral and psychological symptoms of dementia (BPSD), cognitive impairment of Alzheimer's disease (AD) patients and the caregiver burden of their caregivers were investigated in an outpatient memory clinic.
  
  
  METHODS
  Forty-six pairs of AD patients and their family caregivers were involved in this study. Neuropsychiatry Inventory (NPI) was used to estimate BPSD, to which memory symptoms were added as a subcategory of BPSD. MMSE, word fluency, clock drawing test and category-cued memory test were used for cognitive measurement. Zarit burden interview (ZBI) and CES-D were used to assess caregiver burden.
  
  
  RESULTS
  Among 11 BPSD subcategories, memory symptoms, apathy, depression, delusion, aggression and anxiety were prevalent BPSD was a strong determinant of caregiver burden. Among BPSD symptoms, anxiety, aggression and aberrant motor behavior were significantly related to ZBL In terms of the relationship between BPSD and cognitive impairment, the scores for delusion and apathy were significantly related to the cognitive decline. On the other hand, patients who showed symptoms related to memory and depression had higher cognitive function than those who did not.
  
  
  CONCLUSIONS
  These analyses will contribute to better assessment of AD patients and their caregivers, hopefully resulting in better support for them.
