Key finding

THC/CBD (1:2) improved neuropsychiatric symptoms and agitation in severe dementia over the long term without relevant safety issues.

Summary

Prospective observational study (n=19, mean age 81,4 years, 17 women) on THC/CBD (1:2) in severe dementia over up to 13 months in long-term care. Average dose 12,4 mg THC/24,8 mg CBD daily. No treatment-related problems, limited adverse drug reactions. Clinical scores showed marked, time-stable improvement; deprescription of other medications; facilitated care. Pharmacokinetics showed the expected slight reduction in CYP1A2 and CYP2C19 activity.
