Several small studies have investigated the use of cannabinoids in the treatment of pathology and symptomology of Alzheimer’s disease (AD), as well as treatment of the agitation component of BPSD. A handful of these studies showed that the symptoms of BPSD were decreased with the use of cannabinoids. However, due to small sample sizes, study design, and short trial duration of these studies, the efficacy of these agents on BPSD cannot be confirmed. In addition, cannabinoids have demonstrated anti-oxidant and anti-inflammatory effects, and both processes have been indicated as major contributors to the neurologic effects of AD. Some evidence exists that agitation is related to this neuroinflammatory process. This study will examine the effects of cannabinoids on the behavioral and psychological symptoms of individuals with a dementia diagnosis.
Individuals with Alzheimer’s and other forms of dementia often go through a period of significant behavioral and psychological symptoms of dementia (BPSD). It is estimated that up to 90% of persons with dementia (PWD) experience behavior problems at some point. BPSDs can be challenging for both unpaid family caregivers as well as paid caregivers. Family caregivers provide the bulk of care for PWD and number over 15 million. One of the most common types of BPSDs is agitation with a prevalence of up to 87%, based on a recent systematic review. Agitation can lead to impaired daily functioning, prolongation of hospitalization, reduced time to institutionalization, and is associated with higher mortality. Additionally, agitated behavior is associated with increased injury to both patients and caregivers. Based on the 2018 Alzheimer’s disease drug development pipeline report almost 70% of clinical trials related to BPSD are dedicated to agitation behavior. Finding ways to address agitation is necessary to improve overall quality of life for PWD and their caregivers. Currently, there are no medications available specifically for the treatment of BPSDs. The use of benzodiazepines, antipsychotics and mood stabilizing agents are common, but the risks and side effects often outweigh any benefits.

The most common means to obtain CBD rich medical marijuana is from a state licensed dispensary. These dispensaries can be found by searching on any number of dispensary directories (Leafly, Yelp, etc.) or Google Maps.
Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to one’s brain. To effectively treat vascular dementia, a 2016 study by the US National Institute of Health (NIH) found that activating CB2 (cannabinoid) receptors in the brain helped recover better blood flow to the brain. Activating the CB2 receptors with CBD has increased brain cell activity and helped reduce brain cell damage commonly associated with vascular dementia.
CBD and medical cannabis is legally available by prescription only in Alabama,, Arkansas, Connecticut, Delaware, Florida, Georgia, Hawaii, Iowa, Louisiana, Maryland, Minnesota, Missouri, Montana, New Hampshire, New Mexico, New York, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, Utah, Virginia, West Virginia, Wisconsin and Wyoming.
CBD in all forms is prohibited in Idaho and South Dakota. After July 1, 2021, however, CBD and other cannabinoids will be legal for personal use in South Dakota. Idaho will be the only state where possession of cannabis remains illegal for all residents.
Alzheimer’s patients’ brain cells often show a path of rapid decline and destruction. The potential of stimulating brain tissue was recently discovered as a potential benefit of CBD. In clinical trials, CBD has shown the ability to reverse and even prevent the development of Alzheimer’s negative impact. A 2011 study by Australian researchers Tim Karl and Carl Group found that CBD promotes the growth and development of brain cells, reducing the decline of memory and other brain functions.
4) CBD is legal in all 50 States
Despite CBD being sold in health food stores, tobacco shops, on Amazon, etc., and legalization by many US States, the Federal government has not legalized CBD-rich medical cannabis, even when there is little or no THC included. Hemp-based CBD (with less than 0.3% THC) would not technically have this restriction, but the sourcing and labeling risks are many. Officials in Idaho and South Dakota have said they still consider hemp-based CBD illegal, though South Dakota voters recently voted to change the law and cannabis will become legal for personal use there beginning in July 2021.Medical-based CBD has been legalized in more than 30 states and is recreationally legal in a growing number of US locations. The US Federal Drug Administration recently has approved one CBD medication, Epidiolex, to treat rare forms of epilepsy in patients 2 years and older.
Laws by State
CBD and medical cannabis is legally available to all adult users (21+) in Alaska, Arizona, California, Colorado, District of Columbia, Illinois, Maine, Massachusetts, Michigan, Nevada, New Jersey, Oregon, Vermont, and Washington. Legally recognized state ID is required for purchase.
Huntington’s disease (HD), also known as Huntington’s chorea, is an inherited disorder that results in death of brain cells. The earliest symptoms are often subtle problems with mood or mental abilities. A general lack of coordination and an unsteady gait often follow. According to 2016 research from the University of Madrid, due to CBD’s effectiveness as antioxidants and its anti-inflammatory properties, CBD can be beneficial for managing Huntington’s disease. Experiments with mice have shown that another chemical called cannabigerol, or CBG, in marijuana plants can help maintain brain health for people with Huntington’s (see next section).
Despite CBD being sold in health food stores, tobacco shops, on Amazon, etc., its legal status remains convoluted. The federal government has said since 2018 that CBD with less than 0.3%THC is federally legal. Individual states, however, have their own rules.
