Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a neurological disorder characterized by the gradual loss of myelin, the protective covering of nerves. This condition leads to weakness, numbness, and pain, primarily affecting the arms and legs. CIDP is considered an autoimmune disease, where the body's immune system mistakenly attacks its own nerve tissues. Diagnosis typically involves clinical evaluation, nerve conduction studies, and sometimes a lumbar puncture to analyze cerebrospinal fluid. Treatment options may include corticosteroids, immunotherapy, or plasma exchange to reduce inflammation and improve nerve function. Early intervention is crucial for better outcomes in managing CIDP.
