Tel Aviv, Israel: The administration of plant-derived extracts containing high levels of CBD and low levels of THC reduces agitation in patients suffering from behavioral disturbances related to dementia, according to clinical trial data published in the journal Frontiers in Medicine.
Israeli researchers assessed the safety and efficacy of CBD-dominant extracts (30 to 1 ratio of CBD to THC) compared to placebo in a cohort of seniors (mean age: 79 years) with dementia. Subjects in the trial received sublingual drops of either cannabis extracts or a placebo (olive oil) three times daily for a period of 16 weeks.
“Patients in the investigational group experienced a significantly greater reduction in sleep disturbances, and in agitation and aggression sub-score using two different measurement tools. The improvements were accompanied with non-serious side-effects,” authors reported. “We recommend conducting a large scale randomized controlled trial on behavioral disturbances related to dementia and to compare clinical sub-types of dementia.”
