Slowing Down Alzheimer’s Disease With Cannabis: Does it Work?

Can Cannabis Help People Who Suffer From Alzheimer’s-Related Dementia?

It’s the top-of-mind question for several cannabis researchers, who are delving into recent laboratory findings that indicate that CBD and THC could possibly work together to hinder the buildup of abnormal proteins in the brain.

Research is pointing to cannabis-based treatments having the ability to slow down and potentially stop Alzheimer’s disease, which affects 1 in 3 seniors. Work to date has found an association between THC and lower levels of physical manifestations in people with Alzheimer’s.

Interestingly, cannabinoid chemicals made naturally by the body have been shown to help strengthen immune responses to illnesses and diseases like Alzheimer’s. Yet, as a person ages, this natural production declines, affecting the internal endocannabinoid system (ECS). This shock to the system leaves the body susceptible to illnesses. (Researchers have uncovered that severe illnesses, such as dementia, are linked to a high level of ECS dysfunction.)

THC acts like the body’s naturally-produced cannabinoids, and could potentially bridge the gap to supporting ECS.

As promising new research continues on the possible role that THC could play in slowing down Alzheimer’s disease, patients and their families are hopeful that a potential treatment that will slow, if not halt, the progression of Alzheimer’s-related dementia.

There is limited scientific evidence to support the use of cannabis for people with Alzheimer’s-related dementia. However, some preliminary studies have suggested that compounds in cannabis, such as THC, may have therapeutic potential for treating some symptoms of Alzheimer’s disease, such as:

  1. Reducing agitation: Agitation is a common symptom in people with Alzheimer’s disease and can be distressing for both the person with the disease and their caregivers. Some early studies have suggested that THC may be effective in reducing agitation in people with Alzheimer’s-related dementia.

  2. Improving sleep: People with Alzheimer’s disease often experience disturbances in sleep patterns, which can make their symptoms worse. Some preliminary research has suggested that THC may be effective in improving sleep in people with Alzheimer’s-related dementia.

  3. Managing pain: People with Alzheimer’s disease may experience pain due to various physical and medical conditions. Some preliminary studies have suggested that THC may be effective in reducing pain and improving quality of life for people with Alzheimer’s-related dementia.

However, it’s important to note that much more research is needed to fully understand the effects of cannabis on Alzheimer’s-related dementia, and to determine its safety and efficacy as a treatment option. Additionally, the use of cannabis can have side effects, and it is important to consult with a healthcare professional before using cannabis for medical purposes.

Also, it’s important to keep in mind that the legality of cannabis for medical use varies by jurisdiction, and it may not be available in all areas. If you or a loved one are considering using cannabis for the treatment of Alzheimer’s-related dementia, it’s important to consult with a healthcare professional and to seek out reliable and up-to-date information on its potential benefits and risks
