Autoimmune Diseases in Neurology

Autoimmune diseases occur when the immune system mistakenly attacks healthy tissues. In neurology, these diseases can affect the brain, spinal cord, and nerves.

Common Autoimmune Neurological Disorders

1. Multiple Sclerosis (MS): Immune system attacks the protective covering of nerve fibers (myelin sheath), disrupting communication between the brain and body.

2.NMOSD (Neuromyelitis Optica Spectrum Disorder).
It affects optic nerves and spinal cord. Key features are Optic neuritis,,Transverse myelitis, AQP4-IgG antibodies and treatment includes Steroids, plasma exchange and immunotherapy. For acute attacks, doctors use high-dose steroids to reduce swelling quickly, followed by plasma exchange if needed to remove harmful antibodies from the blood.
3. Myasthenia Gravis: Antibodies block acetylcholine receptors at the neuromuscular junction, leading to muscle weakness and fatigue.
4. Guillain-Barré Syndrome: Immune system attacks peripheral nerves, causing muscle weakness, numbness, and sometimes paralysis.
5. Autoimmune Encephalitis: Inflammation of the brain due to antibodies targeting neuronal proteins, leading to symptoms like seizures, confusion, and memory loss.

Symptoms

– Muscle weakness or paralysis
– Numbness or tingling sensations
– Vision problems (double vision, loss of vision)
– Balance and coordination issues
– Cognitive changes (memory loss, confusion)

 Treatment

– Immunosuppressive therapies: Steroids, plasma exchange, IVIG
– Disease-modifying therapies: For conditions like MS
– Symptomatic management: Physical therapy, pain management
