Una visión alternativa de la Esclerosis Multiple - MS usually strikes between the ages of 15 to 60, with most cases occurring between 20 and 40 years of age. It affects women twice as often as men, and is most prevalent in the northern United States, Canada, and upper Europe, where the climate tends to be temperate. Overall, an estimated 350,000 Americans suffer from MS, which is considered to be incurable by conventional physicians, who also have little understanding about its causes. As the buildup of plaque scars or strips the myelin sheath away from nerve fibers, nerve transmission becomes impaired, and the symptoms of MS begin to appear. They include loss of muscle control, problems with balance and gait, blurry or double vision, chronic pain, chronic fatigue, heightened sensitivity to heat and cold (especially heat, which can worsen other symptoms), and painful tingling sensations in the hands and/or feet.
