Peripheral neuropathy is a condition in which the nerves outside the brain and spinal cord are damaged or malfunctioning. This can result in symptoms such as tingling, numbness, pain, and weakness, typically in the hands and feet. Peripheral neuropathy can be caused by a variety of factors, including diabetes, infections, autoimmune disorders, and genetic factors. Treatment options for peripheral neuropathy may include medications, physical therapy, and lifestyle changes. Research in this area focuses on understanding the underlying causes of peripheral neuropathy, developing new treatments, and improving the quality of life for individuals affected by this condition.
