Healthcare providers are reporting that medical marijuana can help to not only subdue some of the behaviors that come with dementia but also to slow the progress of conditions that cause dementia.

Medical marijuana is rapidly gaining a reputation among healthcare professionals as a safe and effective treatment for a wide array of maladies. Today, many medical practitioners treating patients for dementia recognize medical marijuana’s potential in treating patients with conditions such as Alzheimer’s disease, the most common cause of dementia according to the National Institute of Aging.

Symptoms of Alzheimer’s disease in most individuals generally begin to manifest in their mid-60’s, although early-onset dementia can sometimes manifest in patients as young as 30 years old.

Shockingly, in the U.S, more than 5.3 million patients over 65 years have been afflicted with Alzheimer’s disease. And another 200,000 individuals suffer from early-onset Alzheimers. That is according to compiled data by the National Alzheimer’s Association. Another frightening statistic indicates that ten percent of people over the age of 65 will develop Alzheimer’s disease. 

Two-thirds of Alzheimer’s patients are women. Also, African-American seniors are twice as vulnerable to the disease as white seniors. Elderly individuals with a Hispanic background are shown to be 1.5 times as susceptible to Alzheimer’s than Caucasians.

As lifespans increase, and more people are living far beyond 65 years of age, the instances of Alzheimer’s disease are expected to soar. 

Other diseases such as Parkinson’s disease and Huntington’s disease are also sometimes responsible for the onset of dementia. 

There have been many positive studies and investigations indicating the efficacy of medical marijuana in treating the ravages of dementia and neurodegenerative conditions such as Alzheimer’s that trigger this heartbreaking condition. 

So What is dementia?

In 1906, Alois Alzheimer, the German psychiatrist for whom the disease was named, discovered upon autopsy that there were dramatic changes in the brain tissue of a deceased dementia patient. Examination of the patient’s brain tissue revealed tangled bundles of fibers called neurofibrillary or tau tangles, and also abnormal clumps of proteins known as amyloid plaques.

This severe damage to the brain causes a significant loss of communication between neurons. In the beginning stages of dementia, the symptoms are mild and include confusion and forgetfulness. In the final, deadly stages these conditions result in the irreversible shrinking of brain tissue. 

According to Mayo Clinic’s researchers, as the condition worsens, it causes tremendous shifts in personality and makes rudimentary, day-to-day tasks impossible. 

Dementia patients often develop some of the following traits:

  • Depression

  • Apathy

  • Social withdrawal

  • Mood swings

  • Distrust in others

  • Irritability and aggressiveness

  • Changes in sleeping habits

  • Wandering

  • Loss of inhibitions

  • Delusional thinking

In the final stages of the disease, patients will lose conversational skills, as well as the ability to read. Functions and skills learned in the developing years of childhood are often the last to disappear. 

Difficulties In Dementia patients That often develop

For example, performing basic functions such as swallowing can become extremely difficult leading to aspiration pneumonia (fluid in the lugs). In fact, according to Dr. Marc Gordon, chief of neurology at Zucker Hillside Hospital in Queens, New York, aspiration pneumonia is responsible for the demise of two-thirds of dementia patients. 

Another lurking danger is the inability to walk, which greatly increases the development of deadly blood clots.

One of the main reasons dementia patients are susceptible to infections, according to The National Institute on Aging, is a weakened immune response due to extreme weight loss.

No Definitive Cause

Research has yet to come up with a definitive cause of Alzheimer’s. Scientists now believe a combination of environmental, genetic, and lifestyle factors may be responsible for the onset of dementia. In approximately 50 percent of cases, Alzheimer’s appears to be triggered by specific genetic mutations. In these specific cases, patients invariably develop the condition.

At this time, no cure for dementia or Alzheimers exists. However, there are several options and methods for retarding the progression of damage to the brain. These protocols may offer a far better quality of life for many individuals suffering from dementia.

Using Medical marijuana for dementia treatment

Cannabis Now reports many nursing homes across the U.S. are embracing the utilization of medical cannabis to alleviate the ravages of dementia.

According to an article in, behavioral symptoms of dementia including aggression and agitation are being successfully managed with medical cannabis. There is also strong evidence indicating the efficacy of cannabis in targeting the underlying processes that trigger Alzheimer’s Disease.

Frontiers in Pharmacology recently published a research paper revealing CBD’s ability to relieve some of the debilitating symptoms associated with Alzheimer’s disease. CBD is the non-intoxicating analog to THC, the compound in marijuana that causes a high. THC and CBD are the two most abundant cannabinoids in medical marijuana. 

In the paper, the antioxidant, neuroprotective, and anti-inflammatory properties of CBD were thoroughly researched and reviewed. The results of the study were promising, indicating the ability of cannabis to mitigate cognitive impairment associated with Alzheimer’s.

Further reports on this groundbreaking research show CBD’s capabilities in not only promoting neurogenesis or the growth and development of neurons but also in retarding further degeneration of cognitive functions.

The paper also reports on a study conducted on mice with Alzheimer’s disease. The mice in the study were administered CBD on a daily basis for three weeks. A significant reduction in neurodegeneration was indicated. Moreover, when the mice were treated with cannabis over the course of eight months, some social recognition memory was restored.

Another preliminary study took place at the Salk Institute for Biological Studies (La Jolla, California) in which researchers harvested human brain tissue with toxic proteins closely linked to Alzheimer’s disease. When the neurons were exposed to cannabinoids such as CBD and THC, the toxic proteins were eradicated, inflammation was reduced, and the neurons remained viable.

The active compounds in cannabis naturally target the human endocannabinoid system (ECS). A wide array of bodily functions are regulated by the ECS. Supplementing the body’s own endocannabinoids with those produced in cannabis has been shown to help control the activity of immune cells and prevent neuronal damage caused by an over-activated immune system and slow the progression of Alzheimer’s and other neurodegenerative disorders such as Parkinson’s and Huntington’s diseases.

For human patients, the choice of medical marijuana delivery methods is generally limited to the use of tinctures, especially in later stages of the disease. In the early stages, edible forms of marijuana have also been used.
