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.
Prolactinoma is one type of tumor that develops in the pituitary gland. The cause of these tumors is unknown. The pituitary gland is a small bean-shaped gland situated at the base of your brain. Despite its small size, the pituitary gland influences nearly every part of your body. Its hormones help regulate important functions such as growth, blood pressure and reproduction.
