Behavioral and Psychological Symptoms in Dementia

Behavioral and psychological symptoms (BPS) are common in dementia and may help in differential diagnosis of the various subtypes, a new study found. The study comprised 806 patients with dementia (cVaD-136, sVaD-184, AD-486) recruited from outpatient consultations. Researchers found:

  • BPS were reported in 98.5%, 97.3%, and 96.9% of the cVaD, sVaD, and AD cases, respectively.
  • The median Neuropsychiatric Inventory (NPI) score was 36 in both cVaD and sVaD and 34 in AD, with a median number of 4 symptoms per patient.
  • The most frequent disorders were depression, apathy, and sleep disturbance.
