Is Long-Term Use Of Cannabis Extracts Safe And Effective For Dementia Patients?

Geneva, Switzerland: The administration of plant-derived extracts containing a two-to-one ratio of CBD to THC is associated with behavioral improvements and few adverse side effects in dementia patients, according to data published in the journal Frontiers in Aging Neuroscience.

A team of Swiss researchers assessed the long-term safety and efficacy of the adjunctive use of cannabis extracts in a cohort of dementia patients (mean age: 81 years). Participants received an average of 12.4 mgs of THC and 24.8 mgs of CBD per day for up to 13 months.

Investigators reported “marked improvements” in patients’ symptoms over the course of the trial, including reduced agitation. They reported “no problems related to the treatment and limited adverse drug reactions.”

They concluded, “A long-term THC/CBD (1:2) medication can be administered safely and with overall positive clinical improvement to poly medicated older adults with severe dementia and associated problems.”

The study’s results are similar to those recently reported in a placebo-controlled trial which determined that the sublingual administration of CBD-dominant plant extracts reduced agitation and improved sleep in dementia patients.
