The Neuropsychiatric Inventory: assessing psychopathology in dementia patients
Cummings JL.. Neurology, 1997-05-01
Topic: Risk, prevention and care in population studies
Plain-language summary
The Neuropsychiatric Inventory (NPI) was developed to assess psychopathology in dementia patients. It evaluates 12 neuropsychiatric disturbances common in dementia: delusions, hallucinations, agitation, dysphoria, anxiety, apathy, irritability, euphoria, disinhibition, aberrant motor behavior, night-time behavior disturbances, and appetite and eating abnormalities. The severity and frequency of each neuropsychiatric symptom are rated on the basis of scripted questions administered to the patient's caregiver. The NPI also assesses the amount of caregiver distress engendered by each of the neuropsychiatric disorders. A total NPI score and a total caregiver distress score are calculated, in addition to the scores for the individual symptom domains. Content validity, concurrent validity, inter-rater reliability, and test-retest reliability of the NPI are established. Different neurologic disorders have characteristic neuropsychiatric manifestations and distinctive NPI profiles. The NPI is sensitive to treatment effects and has demonstrated the amelioration of behavioral symptoms in Alzheimer's disease by cholinergic agents. The NPI is a useful instrument for characterizing the psychopathology of dementia syndromes, investigating the neurobiology of brain disorders with neuropsychiatric manifestations, distinguishing among different dementia syndromes, and assessing the efficacy of treatment.
What this study adds
Evidence grade: Low
This is a narrative review. This 1997 review describes the Neuropsychiatric Inventory (NPI), which rates how often and how severely 12 behaviour and mood changes occur in dementia, such as delusions, agitation, apathy, night-time disturbance and eating changes. A caregiver answers scripted questions, and the tool also scores how much distress each symptom causes the caregiver.
Taken from this record’s own fields, not from reading the paper. The grade is assigned from the abstract’s wording; what that means.

Key findings
- The NPI is sensitive to treatment effects and has demonstrated the amelioration of behavioral symptoms in Alzheimer's disease by cholinergic agents.
Why it matters
This 1997 review describes the Neuropsychiatric Inventory (NPI), which rates how often and how severely 12 behaviour and mood changes occur in dementia, such as delusions, agitation, apathy, night-time disturbance and eating changes. A caregiver answers scripted questions, and the tool also scores how much distress each symptom causes the caregiver. The review states that the NPI is valid, reliable and able to detect treatment effects, including improvement with "cholinergic agents", but this record gives no figures, trials or patient numbers, so it explains how behaviour symptoms are measured rather than showing that any treatment works.
