Topic: Risk, prevention and care in population studies

Behavioral and psychological symptoms are highly prevalent in dementia. The Neuropsychiatric Inventory was constructed to measure these symptoms. Data from three studies are presented concerning psychometric aspects of the NPI Dutch version.

Key findings

Why it matters

This work presents psychometric data on the Dutch version of the Neuropsychiatric Inventory, a tool for measuring behavioral and psychological symptoms of dementia. It concerns symptom measurement only and does not address treating, curing or preventing Alzheimer's disease.
