Other factors involved in MS
In cases where there is no apparent evidence of inoculation, or any reason for pathology of the peripheral nerves, the cause can be found in a gradual decline of the nervous system and the immune system. Having high levels of sugar in the blood overtime leads to neuropathy. As greed is a gradual development in a person's character, the nervous system and the immune system gradually decline through the years either by wrong eating habits, high levels of sugar in the blood, emotional stress, low reserved energy, toxin overload, or constant close exposure to highly polluted air (such as smoking); and these can cause a person to develop MS without ever being inoculated against a pathogen.
When the mind perceives a threat, which can be anything. It could be a particular event that happened, resulting in great loss and misfortune, like the death of a child, or physical abuse. When that happens, the mind will perceive that as a threat and process a whole cascade of events within the brain, and as a result, neural structures in the brain that are involved in emotional behaviour triggers an emotional response from a part of the brain called the limbic system, which in turn stimulate another part of the brain called the hypothalamus, and that triggers a whole different cascade of events that throw into disorder the cardiovascular system, the respiratory system, the neuroendocrine system, and the immune system.
So long before there was any branch of medical science that studies the body's immune system, king Solomon under divine inspiration explains how stress destroys the immune system in the Scripture above, but how does wrong eating habits, smoking and low reserved energy destroys the immune system.
In particular the sub set of T-cells known as suppressor T-cell is mostly affected; for, whereas they use to suppressor and bring to an end the inflammatory response initiated by the body's defensive cells in their onslaught against any non-self material, be it living or dead. They no longer inhibit the rapid inflammatory response rendered upon the foreign substance, to break it down and dispose of it and the body's own damage cells and tissues. Thus the immune system becomes hyperactive, and is designated with the term autoimmune because of the prolonged inflammation.
