Effects of THC-Free CBD Oil on Agitation in Patients With Alzheimer's Disease
This trial tests whether CBD oil with no THC (the compound that causes a high) can ease agitation in people who already have Alzheimer's dementia. It also looks at caregiver burden and quality of life. Some people get CBD, some get placebo, then they switch. It's a Phase 2 trial, testing whether it works and is safe, not yet proven or approved.
