Behavioral Expressions in Alzheimer's Disease
An Analgesic Trial to Reduce Pain and Behavior Disruptions in Nursing Home Residents With Alzheimer's Disease

Intervention / Treatment
Detailed Description
The research study will investigate if routine analgesic use will reduce behavioral expressions of dementia and pain in older adults with Alzheimer's disease or other dementias. Using a randomized, placebo-controlled, double-blind, cross-over design, the investigators will compare effects of a routine acetaminophen intervention (650 mg administered routinely by mouth three times per day for 4 weeks) to those of routine placebo (methylcellulose), also given for 4 weeks. The maximum dose to be administered will be 1,950 mg per 24 hours, which is below the current FDA recommendations (maximum dose of 3,000 mg/day).
Participants will be randomly assigned to either treatment or placebo group. The initial treatment phase will last for 4 weeks. At the end of the first 4 weeks, the treatment will be reversed after a 3 day washout period. During the 2nd intervention period, the study drug will be reversed (those receiving acetaminophen will receive the placebo drug and vice versa). The second treatment phase will last for 4 weeks. At the end of 2nd treatment phase, all study treatments will be discontinued

---|---|
Acetaminophen, then placebo
Participants in this group will receive acetaminophen for the first four weeks, then placebo for the next four weeks.
|
Acetaminophen (regular strength) will be provided in two capsules: 325 mg, take two capsules 3 times/day for 28 days (1,950 maximum daily dose).
Capsules will be labeled to maintain blinding.
Other Names:
The placebo will be provided in the same type of capsules as the acetaminophen.
Two capsules, given 3x a day for 28 days.
Capsules will be labeled to maintain binding.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mobilization-Observation-Behaviour-Intensity-Dementia Pain Scale (MOBID-2) will be used for changes between the groups at baseline, weeks 2, 4, 6 and 8
Time Frame: Change from baseline, weeks 2, 4, 6 and 8
|
The MOBID-2 is a two-part, observational pain behavior measure.
Part 1 assesses pain related to the musculoskeletal system (the most common cause of pain in older adults) during a set of standardized, guided movements during morning care (5 items).
Part 2 assesses pain that might originate from internal organs, head, and skin and is monitored over time (5 items).
If a pain behavior is detected, pain intensity is rated using a 0-10 numerical rating scale.
|
Change from baseline, weeks 2, 4, 6 and 8
|
Cohen-Mansfield Agitation Inventory (CMAI) will be used for changes between the groups at baseline, weeks 2,4, 6 and 8
Time Frame: Change from baseline, weeks 2, 4, 6 and 8
|
The CMAI is a 29-item instrument designed to measure the frequency with which persons with dementia display agitation and other behavioral disturbances.
The measure consists of 4 subscales that measure aggressive behavior (hitting, scratching, cursing), physical non-aggressive behavior (pacing, restlessness, disrobing), verbally agitated behavior (complaining, repetitive questions, negativism) and hiding/hoarding.
Item frequency is scored on a 1 to 7 scale, with (1) = never, (2) = < once per week, (3) once or twice per week, (4) several times per week, (5) once or twice per day, (6) several times per day, or (7) several times per hour.
Total scores range from 29-203.
