Neuropsychiatric Inventory (NPI)
Time frame: Screening, baseline, T= 2 weeks (by telephone interview) and T=3 weeks
The NPI has been accepted as the standard measure of NPS in most clinical trials, due to high validity, good inter-rater reliability, high internal consistency and its sensitivity to drug treatment effects. In clinical practice as well as clinical research the NPI is the most commonly used instrument to assess behavioral changes. The NPI evaluates 12 behavioral domains. The frequency and severity
Sponsor's own description
This is a phase II, randomized, placebo-controlled, double-blind, parallel-group, multicentre study to the efficacy and safety of low dose delta-9-THC in behavioural disturbances and pain in patients with mild to severe dementia, when added to an analgesic treatment with acetaminophen. It is hypothesized that Namisol® will lead to more behavioural disturbances than placebo, when added to an analgesic treatment with acetaminophen, and as measured by a change in Neuropsychiatric Inventory (NPI) score, after a three week treatment period. It is expected that this will be due, primarily, to psychoactive effects of Namisol® and secondary to a reduction in pain sensation (as measured with VRS and PACSLAC-D). It is expected that a reduction in NPS will positively affect quality of life and lead to better functioning in daily living.
