CNS demyelinating autoimmune diseases are autoimmune diseases which primarily affect the central nervous system.[1]

Types

Examples include:

Presentation

Since the neural impulse is inhibited in this condition it may lead to paresthesia, muscle weakness, unsteady gait, paralysis, vision loss and other motor dysfunctions.

Causes

CNS demyelination autoimmune disease causes the myelin sheath to deteriorate since the sense of recognition of self is lost. The loss of the myelin insulation either disrupts or prevents neural conduction along the nerve cell's axon.

Nervous System

The brain and the spinal cord are the essential components of the central nervous system and it is responsible for the integration of the signals received from the afferent nerves and initiates action. The nerve cells, known as neurons, carry impulses throughout the body and the nerve impulses are carried along the axon. These microscopic nerve fibers, where the action potential occurs, are protected by a white, fatty tissue that surrounds and insulates it, known as the myelin sheath. This insulation helps the axon of a nerve cell with the conduction and speed of the signal along the axon.

Pathogenesis

The pathogenesis of the demyelination can vary. Some of the factors that contribute to the deteriorating of the myelin are due to inflammatory processes, acquired metabolic derangements, viral demyelination, and hypoxic-ischaemic demyelination.

The nucleus lentiformis, or nucleus lenticularis, constitutes a wedge-shaped mass,whose base is directed outward and the apex inward. It lies lateral and, at the sametime, ventral to the nucleus caudatus and thalamus, Separated from the latter by theinternal capsule. In front and ventrally, the lenticular nucleus is directly continuouswith the head of the nucleus caudatus. Dorsally, delicate gray stripes connect the twonuclei; hence the designation corpus striatum applied to the nuclei conjointly. Thenucleus lentiformis bounds the internal capsule laterally with its downward and inwardsloping medial surface. Its shghtly convex lateral surface is vertical and borders thecapsula externa, a thin white medullary lamella which is limited externally by a
