Peripheral Nervous System Disorders refer to conditions that affect the nerves outside the brain and spinal cord. These disorders can disrupt communication between the central nervous system and the rest of the body, leading to symptoms such as weakness, numbness, and pain. Common examples include peripheral neuropathy, which often results from diabetes, and Guillain-Barré syndrome, an autoimmune disorder. Diagnosis typically involves physical examinations, nerve conduction studies, and imaging tests. Treatment options may include medications, physical therapy, and lifestyle changes, depending on the specific disorder and its severity. Early intervention can help manage symptoms and improve quality of life.
