Alzheimer’s disease is a highly incapacitating disease responsible for the progressive deterioration of cognitive and mental abilities and is the leading cause of dementia.

Unfortunately, conventional medication for Alzheimer’s is expensive, only slightly effective, and causes a host of unwanted side effects. Additionally, symptoms such as apathy, depression, and even aggression are left unchanged by these medicines.

However, medical marijuana may have numerous benefits for Alzheimer’s. For instance, in slowing progression, improving patients’ memories, plus uplifting mood among other benefits. And unlike conventional medicine, with less intrusive side effects.

Successful animal studies may not prove that the same results will happen in humans. However, some promising results can justify further investigation.

In one study, researchers put some young mice in a pool of water that had a floating platform in the center. Almost immediately, all the mice swam straight for the safety of the platform.

Next, the researchers put old mice in the same pool. The results? The mice frantically swam around in circles looking for a way out without noticing the floating platform.

Then, the researchers took the old mice out of the pool and administered THC to the old mice. In simple words, the old mice got stoned.

The researchers then put the now stoned, old mice into the pool once more.

This time things were different. The old mice did not waste time frantically moving in circles and swam straight towards the floating platform instead.

Several studies like these have been conducted to investigate whether marijuana may be a treatment for Alzheimer’s.

Can Medical Marijuana Help Patients with Alzheimer’s?

The cannabinoids, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the main components of marijuana that are studied for their medicinal properties.

THC, besides its medicinal value, is also responsible for making one feel high. Contrastingly, CBD doesn’t cause the high and has many medicinal uses.

Ahead, we’ll have look at how each cannabinoid may benefit Alzheimer’s individually.

Before that though, let us take a look at how marijuana can help Alzheimer’s as a whole.

A holistic approach

Seok Hee Kim et al. reviewed studies on marijuana for Alzheimer’s. And found that both in vivo and in vitro studies suggest that marijuana may hold promise when treating Alzheimer’s in several ways. For example:

  • Reducing cell death in the brain by protecting the brain cells.
  • Stimulating neurogenesis in the hippocampus.
  • Improving memory.

Moreover, the researchers concluded that using both CBD and THC would be more helpful for Alzheimer’s compared to using each cannabinoid individually.

In vivo studies: These studies take place within living organisms. For example, mice.

In vitro studies: These studies happen outside living organisms. For instance, in test tubes or lab dishes.

Alzheimer’s and THC

As mentioned earlier, THC has a ton of medicinal benefits despite being the psychoactive compound in marijuana. Its benefits are evident in the treatment of conditions such as glaucoma, chronic pain, cancer, IBD, and as we’ll see, Alzheimer’s.

According to a preclinical study published in the Journal of Alzheimer’s Disease THC may slow the production of beta-amyloid proteins. Why is this significant?

Beta-amyloid proteins are proteins produced in the brain that are toxic to neurons. It’s assumed that beta-amyloid proteins are a fundamental feature and key contributor to the progression of Alzheimer’s.

Other studies also support THC’s ability to inhibit the production of these toxic amyloid plaques.

Additionally, THC inhibits the production of these toxic amyloid plaques and stimulates their removal. As a result, the inflammatory response of these proteins is blocked and cell death is minimized.

Finally, M.E. Sichler and colleagues observed improved memory and lessened neuronal loss after treating Alzheimer’s disease mice with THCsuggesting that the same could happen when treating Alzheimer’s in humans.

In summary, Alzheimer’s and THC could lead to:

  • Reduced production of beta-amyloid proteins toxic to neurons.
  • Removal of toxic amyloid proteins.
  • Reduced inflammation of neurons and therefore reduced cell death.
  • Possible improvement of memory in Alzheimer’s patients.

CBD and Alzheimer’s

Cannabidiol (CBD) is usually preferred for medical use over THC because of its non-intoxicating properties. CBD is especially useful in the treatment of conditions such as epilepsy, PTSD, multiple sclerosis, and yes, Alzheimer’s disease.

Many scientists believe that brain inflammation is a major contributor to Alzheimer’s disease.

Brain inflammation increases the number of amyloid plaques and neurofibrillary tangles, which spur greater inflammation, microglial activation, and further brain cell death.

CBD’s anti-inflammatory properties, therefore, make it a great option when addressing brain inflammation. Additionally, CBD has far less brutal side effects when compared to conventional anti-inflammatory medication or microglial inhibitors.

By addressing brain inflammation, CBD may help in the treatment of Alzheimer’s through:

  • Reducing amyloid plaques.
  • Preventing the development of neurofibrillary tangles.
  • Blocking the activation of microglia and the release of toxic chemicals.
  • Soaking up free radicals.

CBD oil and Alzheimer’s

Cannabis oil or CBD oil can’t be ignored when it comes to treating any debilitating condition with medical marijuana.

Is this the result of aggressive marketing by CBD oil manufacturers? Or is it because of testimonies from patients who’ve experienced relief from CBD oil?

Well, the presence of CBD is an indication that CBD oils may have medicinal value.

Whether the content of a particular CBD oil matches its labeling is another story. And that’s why CBD oils are so difficult to evaluate medically. To clarify, CBD oils aren’t medical products; so their claims shouldn’t be taken as medical advice.

Nonetheless, reputable CBD oil manufacturers make the case for the use of commercially available CBD oils for medicinal purposes. This is because their products undergo third-party testing to verify that their labeling matches their content.

So how can CBD oil be beneficial for Alzheimer’s patients?

Well, as mentioned earlier, the CBD in cannabis oil could help reduce inflammation, consequently reducing amyloid plaques and the formation of tangles among other benefits.

Can CBD help with dementia?

Dementia is a collective term used to describe various symptoms of cognitive decline such as memory loss, and difficulty in communication, and thinking. And, dementia is usually an outcome of Alzheimer’s disease.

CBD may help with dementia because of its anti-inflammatory and antioxidant properties, which prevent brain cell death. This way, cognitive deterioration is stopped and memory may be enhanced.

Indica or Sativa for Alzheimer’s

Which is better, Indica or Sativa for Alzheimer’s disease?

Indica strains produce a distinct ‘body high’. An Indica’s body high may manifest as a numbing or tingling sensation throughout the body coupled with feelings of relaxation and sleepiness.

The sedative and body-numbing qualities of the Indica make it the strain of choice when quelling conditions such as chronic pain, anxiety, and insomnia.

Sativa on the other hand delivers a mostly cerebral head high. Often, users experience euphoria, increased motivation, and creativity, plus an uptick in energy.

These qualities make Sativa strains suitable when it comes to eliminating annoyances such as fatigue, and chronic pain. Moreover, Sativa strains also work wonders when it comes to improving appetite.

So, to answer the question: Indica or Sativa for Alzheimer’s? Alzheimer’s patients benefit most from the cerebral effects of Sativa strains.

Apart from the Indica and Sativa strains, hybrid strains are another option for Alzheimer’s patients. These strains combine the best of both Sativa and Indica effects to produce more balanced experiences for patients.

Best Edibles for Alzheimer’s

Administering medical marijuana to Alzheimer’s patients can be an easy process. Methods like smoking may not be suitable for senior patients who have compromised lungs or are too repulsive for those who don’t like the smell of cannabis.

Therefore, edibles have become the go-to when it comes to administering medical cannabis to Alzheimer’s patients.

Greg Spier’s account is a real-life example of when edibles proved best for Alzheimer’s.

Greg Spier, son of Alex Spier, administered granola bar marijuana edibles to his father who was battling Alzheimer’s. According to Greg Spier, marijuana was the only drug that seemed to give his father any reprieve.

The appealing nature of cannabis edibles makes them one of the easiest ways to administer medical marijuana to Alzheimer’s patients.

Moreover, cannabis edibles are available in marijuana dispensaries and come prepackaged and marked according to dosage. So they’re an excellent option to keep track of doses.

The best edibles for Alzheimer’s include:

Cannabis Gummies: The combination of their sugary sweetness plus marijuana make them a potent option when it comes to picking edibles. Alzheimer’s patients may be more open to sampling this form of medical marijuana because of their appealing looks and taste.

Cannabis Brownies: Outstandingly delicious and familiar make cannabis brownies appealing when it comes to delivering marijuana edibles.

Weed Chocolates: These are some of the few forms of medical marijuana that provide room for microdosing. Patients can take bites from their tasty infused chocolate bars throughout the day while enjoying the benefits of marijuana.

Cannabis Truffles: These are another visually appealing set of edibles that create a sense of occasion and patients will be eager to bite into them.

Cannabis mints: When it comes to ease of delivery, nothing comes close to cannabis mints. They don’t feel like a meal, are discrete, and deliver medicinal cannabis as effectively as other edibles.

Most importantly, when it comes to taking cannabis edibles going slow is well advised. Edibles are unpredictable, more potent, and last longer than other forms of medical marijuana. So, taking too much could likely overwhelm patients.

Microdosing: this is a method of taking a very low dose of a drug over some time.

Speak to a Medical Marijuana Doctor

When looking into marijuana for medical use, patients need to seek the opinion of an experienced cannabis doctor. Why?

Because proper guidance from a professional cannabis doctor will result in a successful medical marijuana treatment. Moreover, to access medical marijuana, patients need a marijuana doctor’s recommendation. Then, after getting their MMJ recommendation, can they apply for a medical marijuana card.

So if you are seeking medical marijuana for yourself or your loved one with Alzheimer’s, you can book your appointment with Quick Med Cards, attend your online marijuana evaluation and get a medical marijuana recommendation.

Patients in the following states can get a medical marijuana card for their Alzheimer’s:


In vitro and in vivo studies paint a rosy picture when it comes to marijuana and Alzheimer’s. But, more investigations are required; particularly human trials to draw more concrete conclusions.

Nevertheless, despite the lack of the latter, medical marijuana may still prove useful for Alzheimer’s as evidenced in preclinical studies and patient testimonies.

For a decline in symptoms and an improvement in the quality of life, patients battling Alzheimer’s, and their families should consider medical marijuanait just might be the answer they seek.
