Assessment of Behavioural and Psychological Symptoms Associated with Dementia

Abstract

Neuropsychiatric symptoms (mood, psychotic, and behavioural) are very common in dementia and do not necessarily correlate well with other measures of cognition. However, these symptoms are of great importance, as they are a major source of excess disability, patient distress and caregiver burden and have great impact on the level of care required, and the associated costs. This paper is a review of the most useful outcome measures for behaviour and mood symptoms. Investigators who require a comprehensive instrument to measure neuropsychiatric symptoms in studies of patients with dementia should consider using the Neuropsychiatric Inventory (NPI), the Behavior Rating Scale for Dementia of the Consortium to Establish a Registry for Alzheimer's Disease (CERADBRSD) or, possibly, the Behavioral Pathology in Alzheimer's Disease Scale (BEHAVE-AD). The Cornell Scale for Depression in Dementia and the Dementia Mood Assessment Scale (DMAS) are recommended for evaluating depressive symptoms and the Cohen-Mansfield Agitation Inventory (CMAI) is very useful for evaluating the full range of agitation symptoms.
