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.
A whitish fatty substance that acts like an electrical insulator around certain nerves in the peripheral nervous system. It is thought that the loss of the myelin surrounding the vestibular nerves may influence the development of Meniere'mÃ©niÃ¨re s. diseaseyelinated nerve fibers occur predominantly in the cranial and spinal nerves and compose the white matter of the brain and spinal cord. It is the myelin sheath that gives the whitish color to the areas of white matter.
