In certain inherited diseases, the myelin sheath does not develop properly, or it becomes damaged with time. One of the best-known of these disorders is X-linked adrenoleukodystrophy, or X-ALD, which more severely affects males. In X-ALD, an abnormal fatty substance accumulates in the brain, causing damage to the myelin sheath. Symptoms include progressive loss of thinking skills, muscle weakness and seizures. The disease also affects the adrenal gland, which regulates blood pressure and the body's ability to respond appropriately to stress.
What causes neuromyelitis optica? With NMO, your immune system attacks a substance in your body called myelin â the insulation around your nerves. Specifically, the myelin cells in the spinal cord and optic nerves are attacked. Usually, people with NMO have flare-ups of the disease that may strike months or years apart.
