ClinConnect Summary
This clinical trial is studying whether a medication called nabilone can help reduce agitation in people with Alzheimer's disease (AD). Agitation is a common and difficult-to-treat symptom in AD that can make life harder for both patients and their caregivers. Nabilone is a synthetic form of cannabis that is already used to help patients undergoing chemotherapy. The researchers want to see if it can also improve agitation and other related issues, like overall mental health, caregiver stress, and even pain and nutrition in patients with AD.
To participate in this study, individuals need to be at least 55 years old, diagnosed with Alzheimer's disease, and experiencing significant agitation. Participants will be randomly assigned to receive either nabilone or a placebo (a harmless pill with no active ingredients) for eight weeks. They will also have follow-up visits for an additional eight weeks after treatment. It's important for participants to have a caregiver who can help with visits and assessments. This trial is currently recruiting, and it represents a significant step towards finding safer and more effective treatments for agitation in Alzheimer's patients.
