The behavioral and psychological symptoms of dementia affect up to 80% of long-term facilities residents with severe dementia. They seriously alter the quality of life of patients, relatives, and health professionals. Management involves correcting somatic and psychiatric factors and implementing non-drug interventions. Nevertheless, often drug treatments must be introduced with the limitations related to their effectiveness and adverse effects. The investigators hypothesize that medical cannabinoids will improve neuropsychiatric and behavioral symptoms of patients with severe dementia. The investigators assessed the feasibility and safety of administering a cannabis oil that contains tetrahydrocannabinol (THC) and Cannabidiol (CBD) during an initial study of about two years, observing an overall improvement, excellent tolerance to the treatment, and the possibility of reducing or even stopping other drugs. This research project aims to study the efficacy of medical cannabis oil in improving the quality of life of dementia patients experimenting with behavioral and psychological symptoms.
