Natural supplement palmitoylethanolamide for depression

Chronic pain and depression both come forth from dysfunction of the metabolism in the nerves, spinal cord and brain. The chronic pain signals cause a kind of chronic inflammation in the so-called glial tissue. Result: the pain stays and causes depressed feelings. Now there is an explanation and possible solution.

For many patients, their chronic pain causes displeasure. They feel chronically agitated, depressed, irritated and tense, which is very logical. An American professor and his research team mapped out how this is related on the level of the nervous system and the brain. The researchers also found that the natural pain relief palmitoylethanolamide (PEA) doesn’t only reduce chronic pain, but can also improve the related negative feelings.

Patients treated with PEA for chronic pain often notice they feel better and more positive after several days or weeks. They feel more confident in handling things and are less irritable. We now understand how that works from a biological point of view. The schedule below shows a summary of this. We can see how damage to a nerve, for example related to hernia, diabetes or an accident, can cause a metabolic change in the brain. The positive and recovering effect of the palmitoylethanolamide supplement is shown in the tables within the schedule.

Dysfunction of biological factors with chronic pain and depression

Professor di Marzo’s team researched numerous of biological factors in the brain that are responsible for maintaining chronic pain and several factors that play a role in depression and negative moods. It turns out that both chronic pain and depressed feelings stay present due to several metabolic dysfunctions and that the body tries to compensate by increasing the palmitoylethanolamide levels to protect cells and decrease inflammation. The fact that PEA plays an important role here is something that other researchers had noticed as well. They found that anti-depressants like imipramine, escitalopram and tianeptine could increase the PEA levels in the brain [2].  These types of anti-depressants often have many side effects causing many patients to quit.  It would be more convenient to start using the natural substance PEA immediately. This idea is being supported by the work of di Marzo, who found that PEA indeed has anti- depressant properties on depressed symptoms. The effect turns out to be even better than that of Fluoxetine, as other researchers have claimed [3].

After giving more PEA, Di Marzo and colleagues  found that the self-regulating pain decreased and the anti-depressant effects still increased even further. Both the metabolic dysfunction in the brain as the pain and depression symptoms decreased significantly after treatment with PEA.

The conclusion was:

“… our findings may provide novel insights into neuropathic pain processes and indicate PEA as a new pharmacological tool to treat neuropathic pain and the related negative affective states.”
