Cannabis offers glimmer of hope in Alzheimer’s treatment

With at least half a million Canadians suffering from dementia and that total expected to increase by 66 per cent in 14 years, it’s easy to feel pessimistic about our prospects in combating the most common form of dementia — Alzheimer’s. But there is some reason to be optimistic.

New ways to treat the neurodegenerative disease have been introduced in recent years and researchers are constantly looking for others. Moreover, some of the newest studies suggest cannabis could be used to treat Alzheimer’s in a number of ways.

Last summer, researchers at The Salk Institute for Biological Studies in California found that THC, a psychoactive component of cannabis, was able to remove the plaque that clogs the brain and kills its cells. (This plaque is easy to spot in brain scans of Alzheimer’s patients.)

The researchers also discovered that THC reduced the inflammation caused by the plaque. These findings were in line with those of previous studies that showed cannabinoids played a role in reducing inflammation in the central nervous system.

The Salk researchers’ findings have not yet been tested in clinical trials but they are optimistic. “It is reasonable to conclude that there is a therapeutic potential of cannabinoids for the treatment of Alzheimer’s Disease,” says David Schubert, senior author of the Salk study. 

Cannabis shows promise in treating Alzheimer’s symptoms

In a small study conducted six months earlier, Israeli researchers found that THC helped reduce behavioural and psychological symptoms of dementia such as agitation, aggression, apathy and delusions. The researchers concluded that “adding medical cannabis oil to Alzheimer’s patients’ pharmacotherapy is a safe and promising treatment option.”

Roger Ferreira, a neuroimmunologist who has studied brain inflammation caused by neurodegenerative disease and stroke, says he is encouraged that in jurisdictions where the use of medical marijuana is legal, “cannabis is starting to be used as an alternative pharmacological therapy for agitation related to Alzheimer’s.

“This is especially promising since first-line pharmacological treatments like antipsychotics, sedatives and anxiolytics only display limited efficacy with a number of associated safety and tolerability risks,” says Ferreira, who is also CEO of  Beleave.

Of course, the use of marijuana for medicinal purposes is a controversial topic in medical circles. Some physicians are singing its praises while others are concerned about possible addictive properties and long-term effects. Still, scientists are forging ahead in the exploration of cannabis’ as a potential treatment for conditions — and there is a growing body of evidence that it works.

    My name is Martha, My mom has dementia and Alzheimer’s disease, I took care for my mum. We were managing until these awful vigorous shaking seem to have took over her body, she can’t even hold a cup when it is at its worst and sleep is out of the question which leads to utter exhaustion. We were told that the medication she was on for her restless legs which was something totally different was making the shaking worse. But yet the shaking is part of the dementia. I was making research online on any possible solution that could help my mom and I came across how cannabis oil have helped a lot of people around the world to cure Alzheimer’s and Dementia. I was so happy and relief when I saw this and I knew there was hope for my mom to be well again. I contacted Medicinal Marijuana Resources via E-mail info@medicinalmarijuanaresources.com to get the high quality THC cannabis oil for treatment and prescription on how to use the cannabis oil for treatment of Alzheimer’s and Dementia. My mom started using the cannabis oil for treatment as directed by Medicinal Marijuana Resources physician expert team. Now the Alzheimer’s and Dementia are gone and my mom is well, healthy and strong again

Herbal Cannabis


One of the more popular consumption options is to grind the cannabis bud and smoke it either in a device (like a pipe) or to use rolling papers to roll it into a marijuana cigarette (joint). If you wish to directly consume the cannabis bud but don’t wish to smoke, you can always use a Vaporizer – which is part of Beleave’s harm reduction program.
