Peripheral nerve disorders, also known as peripheral neuropathy, are conditions that occur due to damage to the peripheral nerves. This may mean that the peripheral nerves are unable to carry messages properly from the brain to other parts of the body. Symptoms can depend on which nerves are affected but may include pain, weakness, problems with walking or balance, cramps, tingling, and an inability to feel hot or cold.
What are the most common peripheral nerve disorders?
Diabetic neuropathy is the most common peripheral nerve disorder. However, there are more than 100 types of peripheral nerve disorders. Some are hereditary, such as Charcot-Marie-Tooth disease and Friedreich ataxia. Others, such as Guillain-Barré syndrome, may develop during a person's lifetime.
What is the life expectancy for someone with a peripheral nerve disorder?
It is unclear exactly how much peripheral nerve disorders affect life expectancy. However, a 2023 study found an association with earlier mortality in older adults. The underlying cause of the peripheral nerve disorder may affect life expectancy. A person's doctor can provide them with more accurate information about their outlook based on their individual circumstances.
What are the risk factors for peripheral nerve disorders?
Diabetes is the most common risk factor for peripheral nerve disorders. Other conditions that can increase a person's risk include infections, problems with blood vessels, autoimmune conditions such as rheumatoid arthritis, kidney disease, and liver disease. Physical injury, certain medications, contact with toxic substances, and smoking are also risk factors for peripheral nerve disorders.
