Peripheral Neuropathy: Causes, Diagnosis, and Treatment Options – With Dr. Nasser Zahran

Peripheral neuropathy is one of the most common neurological disorders that significantly impact quality of life. It affects millions of people worldwide, with symptoms ranging from mild tingling to severe pain and motor impairment. In this article, Dr. Nasser Zahran, a consultant neurologist, explains the key causes of the condition, how it is diagnosed, and the latest treatment options available.

 What Is Peripheral Neuropathy?

Peripheral neuropathy is a disorder that affects the peripheral nerves, which are responsible for transmitting signals between the central nervous system (the brain and spinal cord) and the rest of the body. It can lead to loss of sensation, muscle weakness, nerve pain, or balance issues.

 Common Causes of Peripheral Neuropathy:

1. Diabetes (the most common cause)

2. Vitamin deficiencies, especially Vitamin B12

3. Viral or bacterial infections affecting the nerves

4. Autoimmune diseases (e.g., lupus, Guillain-Barré syndrome)

5. Excessive alcohol consumption

6. Exposure to toxins or certain medications (e.g., chemotherapy)

7. Genetic disorders

 Diagnosis With Dr. Nasser Zahran:

Dr. Nasser Zahran highlights the importance of early diagnosis, as effective treatment begins with accurate evaluation, which includes:

• Clinical neurological examination

• Nerve conduction studies (NCS)

• Electromyography (EMG)

• Blood tests to check for diabetes, vitamin levels, liver and kidney function

• MRI scans, when needed, to rule out central causes

 Key Symptoms That Require Evaluation:

• Tingling or numbness in hands or feet

• Burning or stabbing nerve pain

• Muscle weakness or wasting

• Loss of balance or coordination

• Increased sensitivity to touch or pain

 Available Treatment Options:

1. Treating the underlying cause:

Such as tight blood sugar control in diabetic patients.

2. Medications for symptom relief:

• Antidepressants (e.g., duloxetine)

• Anticonvulsants (e.g., gabapentin or pregabalin)

• Neuropathic pain relievers

3. Physical therapy:

• Improves muscle strength and balance

• Reduces pain with targeted exercises

4. Electrical nerve stimulation:

• Helps relieve pain and enhance nerve function

5. Vitamins and supplements:

• Especially for cases caused by B12 or folate deficiency

 Dr. Nasser Zahran’s Tips for Prevention and Support:

• Control chronic conditions like diabetes and hypertension

• Avoid smoking and limit alcohol intake

• Eat a balanced diet rich in vitamins

• Exercise regularly

• Schedule regular nerve checkups, especially for diabetics

“Peripheral neuropathy is not an inevitable fate—it can be managed and improved significantly with early diagnosis and a tailored treatment plan,” says Dr. Nasser Zahran.
