Cannabinoids for Behavioral Symptoms in Dementia: An Overview
Pharmacopsychiatry DOI: 10.1055/a-2262-7837Dementia, with loss of memory, cognitive abilities, and independent daily
functioning, is increasing worldwide, related to an aging population. Currently,
there is no curative treatment for dementia. Treatment of the frequently
occurring behavioral and psychological symptoms of dementia (BPSD) is partially
effective and associated with significant side effects. Cannabinoids are lipophilic molecules acting on the CB1 end CB2 receptors,
essential for main biological processes such as sleep, appetite, memory, and
pain. Cannabinoids might have a positive impact on amyloid formation in
Alzheimer’s disease, the main form of dementia, and on BPSD symptoms. Most
knowledge currently concerns delta-9-tetrahydrocannabinol (THC) and cannabidiol
(CBD). In the context of dementia and BPSD, THC might be beneficial for
associated spasticity and possible pain or lack of appetite and CBD probably
works better on sleep, agitation, and anxiety. This overview of prospective clinical studies and randomized clinical trials,
published between 2005 and April 2023, using cannabinoids for BPSD suggests that
older studies using low-dose oral synthetic THC showed no positive results.
Still, more recent studies using THC/CBD-based oral medication at higher doses
show promising results and are feasible and safe in ...
