Peripheral Neuropathy

Peripheral neuropathy encompasses disorders of peripheral nerves leading to sensory, motor, or autonomic deficits. Etiologies include diabetes, toxins, infections, autoimmune disease, and hereditary disorders. Pathophysiology involves axonal degeneration, demyelination, or ischemic injury. Diagnosis relies on clinical evaluation, nerve conduction studies, and laboratory assessment. Management targets underlying causes, symptom control, and rehabilitation; prognosis varies depending on etiology and severity.
