noun. A hereditary disorder or illness that is marked by the decomposition of the myelin sheath which encompasses the brain's nerves as well as the ongoing decomposition of the adrenal gland. When this occurs, the nerves begin to behave irregularly which elicits many alterations within the body, both physically and attitudinally, such as the capacity of motor skills, speech, the capacity to eat and feed oneself, mental processes, the ability to focus on subjects or intellectual materials, and more. The most well-known kind of this disorder is that which is tied to the childhood X-chromosome. This kind presents the most danger to human functioning.
