The Use of Dispensary-Obtained Tetrahydrocannabinol as a Treatment for Neuropsychiatric Symptoms of Dementia

/by

Neuropsychiatric symptoms (NPS) of dementia represent a large driver of health care costs, caregiver burden, and institutionalization of people with dementia. Management options are limited, and antipsychotics are often used, although they carry a significant side effect profile. One novel option is tetrahydrocannabinol (THC); however, in the US, to obtain THC for patients with dementia, caregivers have to go to a commercial dispensary. We evaluated the effectiveness of dispensary-obtained THC for patients with dementia and NPS. Two independent reviewers reviewed charts of patients with diagnosed dementia (N = 50) seen in geriatric psychiatry between 2017 and 2021 for whom dispensary-obtained THC was recommended. The primary outcome was effectiveness in treating NPS; secondary outcomes were the proportion of caregivers who obtained and administered THC (uptake), post-THC antipsychotic use, and adverse reactions leading to treatment discontinuation.

The Effect of Cannabidiol 3% on Neuropsychiatric Symptoms in Dementia – Six-Month Follow-Up

/by

To investigate the beneficial outcomes of giving cannabidiol (CBD) 3% over a six-month period in the BPSD, the management of which is a crucial issue for everyday clinical praxis and to compare the progress in BPSD of patients who receive Cannabidiol 3% with those who follow usual medical treatment (UMT) in everyday clinical praxis. A total of 20 PwD with severe BPSD were recruited from the database of Alzheimer Hellas with NPI score >30. Ten of them were assigned to UMT, while ten were assigned to a six-month treatment with CBD drops. The follow-up assessment was performed with NPI, both clinically and by structured telephone interview.

Cannabis sativa and Cannabidiol: A Therapeutic Strategy for the Treatment of Neurodegenerative Diseases?

/by

This work is a literature review, presenting the current state of the use of cannabinoids on neurodegenerative diseases. The emphasis is on Parkinson’s (PD) and Alzheimer’s (AD) diseases, the two most prevalent neurological diseases. The review goes from Cannabis sativa and its hundreds of bioactive compounds to Δ9-tetrahydrocannabinol (THC) and mainly cannabidiol (CBD) and their interactions with the endocannabinoid receptors (CB1 and CB2).

Cannabinoids for behavioral symptoms in severe dementia: Safety and feasibility in a long-term pilot observational study in nineteen patients

/by

The management of behavioral symptoms and rigidity in patients with dementia constitutes a significant challenge. Short-term studies suggest an interest in the use of medical cannabis, but long-term data are lacking. The objective of this study was to investigate the feasibility and long-term safety of administering tetrahydrocannabinol/cannabidiol (THC/CBD) treatment as an additional drug to a poly medicated population with severe dementia, evaluate clinical improvements, and collect information on the pharmacokinetics of cannabinoids and possible drug–drug interactions.

The balance between detrimental, pro-aging, often stochastic processes and counteracting homeostatic mechanisms largely determines the progression of aging. There is substantial evidence suggesting that the endocannabinoid system (ECS) is part of the latter system because it m…
