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.
Demyelination is the breakdown of the protective covering of the nerve fibers in the spinal cord and brain. This protective covering, called a myelin sheath, helps promote proper nerve function. Demyelination is a condition known as demyelinating disease.There are several causes of demyelination.Myelin, found in the insulating white matter around the nerves, is an important part of the nerves. During transmission of information, myelin has the responsibility of receiving and interpreting the messages sent from the brain.here are several causes of demyelination.
