New clinical trial finds THC/CBD treatment shows promise for dementia-related agitationCanva still imageLEXINGTON, Ky. (ABC 36 NEWS NOW via LEX NEWS) — Dementia affects more than memory. And as the disease progresses, agitation can become one of its most troubling symptoms. Dr. Gregory Jicha, the University of Kentucky’s director of clinical trials, said agitation is a significant concern in later stages of the disease. “Over 40% of all patients in the later stages of disease will present with agitation,” Jicha said. That’s where the Phase 2 LIBBY clinical trial comes in.
