Multiple sclerosis is an autoimmune disease that affects the brain and spinal cord (central nervous system). Multiple sclerosis (MS) affects women more than men. The disorder is most commonly diagnosed between ages 20 to 40, but it can be seen at any age. MS is caused by damage to the myelin sheath. This sheath is the protective covering that surrounds nerve cells.
Typically benign tumors, adenomas often press on the pituitary gland, causing loss of function of one or more hormones. Many pituitary adenomas are called âfunctioning tumorsâ because they actually make hormones and may cause an increase in hormone levels instead of a decrease.
Growth hormone deficiency is a disorder that involves the pituitary gland (the small gland at the base of the brain that secretes several hormones, including growth hormone). A damaged or malfunctioning pituitary gland may not produce enough hormones for normal growth.
