Aggression, restlessness and emotional distress may affect people with late-stage dementia, also profoundly affecting their caregivers. Researchers at Georgetown University Medical Center note that current treatments are limited. Their alternative is a combination of two active ingredients found in marijuana—THC and CBD. Results of a clinical trial show that a special medical formulation of the two ingredients brought significantly less agitation in nearly ninety percent of patients after twelve weeks, compared to those receiving a placebo. The researchers caution that the medication used in this trial was specially formulated and closely supervised. People should not assume products available online or at dispensaries are the same as that in the study.
