John Coleman is an Australian naturopath who suffered stage 4 Parkinson's, and was able to eliminate his symptoms and has counseled thousands of Parkinson's patients. Coleman says there is "no cure" for Parkinson's, but each case has a specific etiology that, if understood, can be used to address symptoms with diet/food changes, supplements, detox, exercise, and perhaps medical intervention (if there are pathogens involved), etc.
Colemen has written at least three books on Parkinson's, including RETHINKING PARKINSON where the following material on Anandamide appears. Medical dogma today is that symptoms of Parkinson's are caused by a lack of the neurotransmitter dopamine. Anandamide wasn't discovered until 1992. This hormone seems to control "motor skills" and other functions that if failing would create symptoms of Parkinson's.
Biochemical evidence suggests that anandamide is involved in creating and breaking short-term neural connections. Moreover, anandamide is synthesized in areas of the brain that are important for memory, higher thought processes and control of movement. With the modest evidence available to date, it seems obvious that production of anandamide is a very important for our health. Much of the evidence so far indicates that it is at least as important as dopamine and serotonin in regulating brain function. It seems to be involved in our movements, memory, sleep, eating, pain control and learning. These are all areas that challenge many of us when diagnosed with Parkinson’s disease.
To my knowledge, Coleman does not suggest that most people diagnosed with Parkinson's have an anadamide deficiency, that idea occurred to me because most of the "therapies" he presents for Parkinson's induce the body to make more Anadamide. e.g., exercise, including dancing, laughing, etc. The book was written in 2019. I was able to find a company that sells the hormone/neurotransmitter anandamide, and while I don't know if the molecule survives digestion intact. I have ordered the product to see how my wife reacts to anadamide.
Strenuous exercise seems to be key to the body's production of anadamide.
A 2004 study of twenty-four college students who ran or bicycled for 40 minutes at 76 per cent of their maximum heart rate showed an 80 per cent increase in anandamide immediately following exercise. The athletes also reported feelings of relaxation, regulated mood and increased appetite.9
Here is the entire section on anadamide.
Anandamide “The Bliss Hormone”
Anandamide is a neurotransmitter (not really a hormone) found in human organs, especially the brain. It is nicknamed the bliss hormone as it was originally postulated to be the natural substance mimicked by THC (Δ9-tetrahyrocannabinol), the principle psychoactive ingredient in cannabis (marijuana). THC locks onto cannabinoid receptors first discovered in 1988. THC does not occur naturally in the body, and our body does not create receptors for substances it doesn’t produce, so scientists were certain that some sort of endogenous (made in the body) substance was produced to occupy the receptors sites locked onto by cannabis.
Israeli scientist Raphael Mechoulam discovered anandamide (more properly named arachidonoylethanolamine or AEA) in 1992. Anandamide connects with CB1 cannabinoid receptors found in the brain and nervous system, and CB2 receptors found throughout the rest of the body. The difference is quite important as anandamide plays various roles in our health. The CB2 receptors are involved in the health of our immune system, while the CB1 receptors seem to be concerned with a variety of tasks including memory, eating behaviour, sleep and pain relief. They also seem to influence the neural generation of motivation and pleasure.
Anandamide is critical in the early development of babies in the uterus (while THC from cannabis may cause disruption or abortion of pregnancy). We learn to remember new knowledge or carry out new activities by creating new connections between neurons. The more we use each connection – that is, practice the memory or activity – the stronger that connection becomes. If we stop using that connection, it becomes weak and may break. This has profound implications in recovery and we will explore it further in a later chapter.
Biochemical evidence suggests that anandamide is involved in creating and breaking short-term neural connections. Moreover, anandamide is synthesised in areas of the brain that are important for memory, higher thought processes and control of movement. With the modest evidence available to date, it seems obvious that production of anandamide is a very important for our health. Much of the evidence so far indicates that it is at least as important as dopamine and serotonin in regulating brain function. It seems to be involved in our movements, memory, sleep, eating, pain control and learning. These are all areas that challenge many of us when diagnosed with Parkinson’s disease.
Incidentally, there is at least one study showing that anandamide inhibits the proliferation of human breast cancer cells in vitro, so all women could benefit from increased anandamide.
Finding more anandamide
There is scant Western-scientific evidence on improving production of anandamide in our brain and there is little available from our food. However, we have seen very significant increases in anandamide in the blood of long-distance runners during the “runner’s high”. This state of being among long-distance runners is fascinating as it treads a fine line between the benefits of meditation and the danger of over-stressing our body.8
A 2004 study of twenty-four college students who ran or bicycled for 40 minutes at 76 per cent of their maximum heart rate showed an 80 per cent increase in anandamide immediately following exercise. The athletes also reported feelings of relaxation, regulated mood and increased appetite.9
Our clinical experience indicates that meditation (relaxation) brings the same benefits of regulated mood and better appetite, plus improved physical performance, so it seems that we can increase anandamide production through meditation. Laughter can produce the same effects, and we know that thinking/speaking lovingly about ourselves increases production of anandamide, dopamine and serotonin. We also now know that appropriate exercise regimens will increase anandamide production. What we are seeing here is a picture of circular dependence. We need anandamide to assist in the reversal of our symptoms and eventual recovery. We can produce more anandamide with exercise and this will help us relax, meditate, eat better, feel better about ourselves and move more freely.
But … when we meditate, we produce more anandamide, so we can exercise better, eat better, feel better about ourselves, relax more and laugh more freely. And … when we laugh, we produce more anandamide, so we can feel better about ourselves, exercise better, eat better, meditate more easily and look at life more joyfully. And … when we think lovingly of ourselves, we produce more anandamide,
