In recent years, there has been a growing body of evidence to suggest that cannabinoids—compounds found in the Cannabis sativa plant—possess antioxidant properties that could potentially be harnessed to treat a variety of central nervous system (CNS) diseases. These diseases include conditions like Alzheimer's disease, Parkinson's disease, and multiple sclerosis.
In 1963, Israeli scientist Dr. Raphael Mechoulam was the first to isolate and identify tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis. Since then, numerous other studies have been conducted on cannabinoids and their potential therapeutic benefits. Let's take a closer look at some of this research and what it might mean for treating CNS diseases.
Cannabinoids as Antioxidants
One of the most promising areas of research into cannabinoids and their potential therapeutic benefits surrounds their role as antioxidants. This is because oxidative stress is thought to play a role in the development of many CNS diseases.
For example, one study found that CBD was able to improve memory and decrease oxidative stress in rats with Alzheimer's disease. Another study looked at the effects of CBD on Huntington's disease and found that it was able to help protect against neuronal death and reduce inflammation.
Cannabinoids as Neuroprotectants
In addition to their antioxidant properties, cannabinoids have also shown promise as neuroprotectants—compounds that help protect against neuronal cell death. This is significant because neuronal cell death is a hallmark feature of many CNS diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis.
Researchers believe that cannabinoids may help protect against neuronal cell death by reducing inflammation and by modulating the body's immune response. In fact, one study found that CBD was able to help reduce inflammation in an animal model of multiple sclerosis.
What is anandamide?
Endocannabinoids may also help protect against neuronal cell death by modulating neurotransmitter release. For example, one study found that anandamide—an endocannabinoid produced naturally by the body—was able to protect dopaminergic neurons against toxicity caused by pesticides in mice.
CBD and help for serious diseases is in our future
While more research is needed to understand how exactly cannabinoids exert their neuroprotective effects, the existing evidence suggests that they may be beneficial in treating various CNS diseases—especially those characterized by oxidative stress or neuronal cell death. If you or someone you know is living with a CNS disease, talk to your doctor about whether taking cannabidiol (CBD) or another cannabinoid could be helpful for you.
