Diagnosis and Treatment of Peripheral Neuropathy

Proper diagnosis of peripheral neuropathy involves a complete medical evaluation to identify the cause, and treatment focuses on managing the underlying condition and relieving symptoms. Since there is no single cure, treatment plans are often customized for the individual.

Diagnosis Process

A healthcare professional will typically use a combination of methods to diagnose peripheral neuropathy.

• Medical and Family History: Your doctor will ask about your symptoms, lifestyle, and any family history of neurological diseases.
• Neurological Exam: This exam evaluates your reflexes, muscle strength and tone, balance, coordination, and ability to feel different sensations such as touch, vibration, and temperature.
• Blood Tests: These can identify underlying causes like diabetes, vitamin deficiencies (especially B12), kidney or liver diseases, and signs of autoimmune disorders.
• Nerve Function Tests: An electromyogram (EMG) and a nerve conduction study measure the electrical activity of your muscles and the speed of electrical signals traveling through your nerves.
• Imaging Tests: A CT scan or MRI can look for physical problems affecting the nerves, such as herniated discs, tumors, or pinched nerves.
• Biopsies: In some cases, a small sample of a nerve or skin may be removed and examined under a microscope to confirm the diagnosis.
• Lumbar Puncture: Your doctor may order a spinal tap to test for abnormal proteins or infections that could be causing the neuropathy.

Medical Treatments

Treatment is tailored to the specific cause of the neuropathy.

• Treating Underlying Conditions: For diabetic neuropathy, blood sugar control is the most critical step. For autoimmune conditions, therapies like plasmapheresis or intravenous immunoglobulin (IVIG) may be used.
• Medications: Over-the-counter pain relievers for mild pain, anti-seizure medications (gabapentin, pregabalin), and certain antidepressants are often effective for nerve pain.

Therapies and Procedures

• Physical Therapy: A physical therapist can create a routine to improve strength, balance, and range of motion.
• Transcutaneous Electrical Nerve Stimulation (TENS): This therapy delivers a gentle electrical current to the skin to help block pain signals.
• Surgery: If neuropathy is caused by nerve compression (such as carpal tunnel syndrome), surgery may be necessary to relieve the pressure.

Lifestyle and Home Care

• Protect Your Feet: Inspect your feet daily for cuts or sores. Wear protective, well-fitting shoes.
• Regular Exercise: Consistent physical activities like walking or swimming can improve blood flow and help with pain management.
• Healthy Diet: A balanced diet rich in fruits, vegetables, and whole grains supports nerve health.
• Avoid Toxins: Excessive alcohol consumption and smoking can damage nerves and worsen neuropathy.
