Cannabis and Dementia: What researchers are saying

Updated: May 23, 2023


Researchers are exploring the potential benefits of using cannabis to treat dementia. While there is still a lot of research to be done, preliminary studies suggest that cannabis may have anti-inflammatory and neuroprotective properties that could make it a potential treatment option for dementia. However, it's important to consider the potential risks and limitations of using cannabis for dementia treatment, including the short-term memory impairment caused by THC and the potential for harmful interactions with other medications. As research continues, we hope to understand better how cannabis can be used to treat dementia effectively.


Looking for information on the potential benefits and risks of using cannabis to treat dementia? We summarise what researchers are saying about the use of cannabis for dementia treatment, including the potential neuroprotective properties of CBD and the short-term memory impairment caused by THC. Read on to learn more.




Dementia is a debilitating condition that affects millions of people worldwide. It is a condition that gradually worsens over time and can lead to memory loss, difficulty communicating, and even difficulty performing basic tasks. As the search for a cure continues, researchers are turning to cannabis as a potential treatment option. We will explore the latest research on cannabis and dementia and what it means for those who live from this condition.


Understanding Dementia

Before we dive into the research on cannabis and dementia, it's essential to understand what dementia is and how it affects the brain. Dementia is a broad term that describes a range of conditions that affect the brain's ability to function correctly. Alzheimer's disease is the most common form of dementia, accounting for 60-80% of all cases.

Dementia affects various brain functions, including memory, language, perception, and judgment. It can also cause changes in mood and behaviour, making it challenging for individuals to carry out daily activities independently.


The Potential of Cannabis for Dementia Treatment

Despite no cure for dementia, research shows that cannabis may offer a potential treatment option. Cannabis contains two main active compounds: tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is known for its psychoactive effects, while CBD is not psychoactive and is believed to have medicinal properties.

Research shows that CBD may have anti-inflammatory and neuroprotective properties, making it a potential treatment option for dementia. In a study on mice conducted by the Schizophrenia Research Institute in New South Wales, Australia, researchers found that CBD positively affected the mice's cognitive abilities and memory.

Another study conducted by the Salk institute found that THC could potentially slow the progression of Alzheimer's disease by reducing the formation of amyloid plaques in the brain. These plaques are a hallmark of Alzheimer's disease and are thought to contribute to the death of brain cells.


The Risks of Cannabis for Dementia Patients

While the potential benefits of cannabis for dementia treatment are promising, it's essential to consider the potential risks. THC can cause short-term memory impairment, which can exacerbate existing dementia symptoms. Additionally, cannabis can interact with other medications, leading to potentially harmful side effects.



What the Experts are Saying

While research on cannabis and dementia is still in its early stages, experts are optimistic about the potential benefits. According to Dr. Danial Schecter, a physician and medical director at the Canabo Medical Clinic in Toronto, "There’s certainly anecdotal evidence that cannabis can help treat dementia, particularly in the early stages."


Dr. Schecter goes on to caution that while cannabis may offer some benefits, it is not a cure for dementia. "We must be realistic about what cannabis can and can't do. It's not a magic bullet, and it's not a cure. But for some patients, it can provide relief from their symptoms."


Dementia is a complex and debilitating condition affecting millions worldwide. While there is no cure, researchers are exploring alternative treatment options such as cannabis. While the potential benefits of cannabis for dementia treatment are promising, it's important to consider the potential risks and limitations. As research continues, we hope to understand better how cannabis can be used to treat dementia effectively.
