• In 11 patients with Alzheimer's disease, a decrease in some values after using hemp oil was found.
  • Tetrahydrocannabinol could be very effective in treating this disease in the future.


Tetrahydrocannabinol (THC) is a potential treatment for Alzheimer's disease (AD).

Measure the efficacy and safety of THC-containing medical cannabis oil (MCO) in addition to pharmacotherapy, in alleviating behavioral and psychological symptoms of dementia (BPSD).

Survey Methods

11 AD patients were admitted into an open, 4 week prospective study


10 patients completed the study. Significant reductions in CGI severity score (6.5-5.7; p <0.01) and NPI scores (44.4-12.8; p <0.01) were noted.

NPI domains of significant decline were: seizures, agitation / aggression, irritability, apathy, sleep, and lack of care.


Adding MCO to the pharmacotherapy of AD patients is safe and promising for additional treatment options
