Summary
This trial is testing dronabinol, a cannabis-based medication, to see if it can reduce agitation in US Veterans with moderate to severe dementia. The study will evaluate the effectiveness of dronabinol and monitor for any side effects. All participants will eventually receive dronabinol during the study. Dronabinol is a synthetic THC that has been previously tested for treating neuropsychiatric symptoms in dementia, showing potential benefits for agitation and behavioral disturbances.
Who is the study for?
This trial is for US Veterans with moderate to severe dementia experiencing significant agitation. Participants must have a stable medication regimen, be able to swallow capsules, and not use cannabinoids or illicit drugs recently. They need a study partner who spends at least 10 hours per week with them and cannot have unstable psychiatric disorders or medical conditions.
What is being tested?
The trial tests the effectiveness of dronabinol in treating agitation in dementia patients compared to a placebo. Each participant will receive both treatments over two phases (8 weeks each) separated by a washout period, ensuring everyone gets dronabinol at some point.
What are the potential side effects?
Potential side effects of dronabinol may include mood changes, dizziness, sleepiness, confusion, hallucinations or worsening of pre-existing heart conditions due to its psychoactive properties.

Experimental Treatment
Group I: Placebo FirstExperimental Treatment1 Intervention
Participants will take matching placebo capsules twice daily for 8 weeks, followed by a three week washout period. They will then begin taking dronabinol 2.5 mg capsules twice daily for 1 week, followed by dronabinol 5 mg twice daily for 6 weeks, followed by dronabinol 2.5 mg twice daily for 1 week.
Group II: Dronabinol FirstExperimental Treatment1 Intervention
Participants will take Dronabinol 2.5 mg capsules twice daily for 1 week, followed by dronabinol 5 mg twice daily for 6 weeks, followed by dronabinol 2.5 mg twice daily for 1 week. They will then undergo a 3-week washout period, followed by placebo capsules twice daily for 8 weeks.

Other Research
Dronabinol, a synthetic cannabinoid agonist, reduces psychomotor agitation by interacting with CB1 receptors in the brain, which helps modulate neurotransmitter release and stabilize neural activity. This is similar to how benzodiazepines enhance the effect of GABA to produce sedative and anxiolytic effects.
Understanding these mechanisms is important for selecting the most appropriate treatment, leading to more effective and targeted management of agitation symptoms.
