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.
Under a microscope, myelin looks like strings of sausages. Cholesterol is an essential constituent of myelin. Myelin is about 40% water; the dry mass is about 70â85% lipids and about 15â30% proteins. Some of the proteins are myelin basic protein, myelin oligodendrocyte glycoprotein, and proteolipid protein.The primary lipid of myelin is a glycolipid called galactocerebroside.nder a microscope, myelin looks like strings of sausages.
