1. Medical History and Symptoms:

There is often a history of exposure to heavy metals (arsenic, mercury, lead) or the use of drugs such as nitrofurazone and isoniazid, or a history of vitamin deficiency, diabetes, uremia, etc.

2. Physical Examination Findings:

1. There may be symmetrical sensory abnormalities (pain, numbness, hypersensitivity, or reduction) predominantly in the distal limbs, often presenting in a glove and stocking distribution.

2. Motor impairment: decreased muscle strength, reduced muscle tone, weakened or absent tendon reflexes, and in advanced stages, muscle atrophy predominantly in the distal limbs.

3. Autonomic dysfunction: cold, pale, cyanotic skin or sweating disorders in the extremities, and the skin may become rough and thin.

3. Auxiliary Examinations:

1. Blood white blood cells may be grade I elevated, nutritional deficiency anemia, and in the case of diabetes, blood and urine sugar levels may be elevated.

2. Electrophysiological examinations, MCV (motor nerve conduction velocity), SCV (sensory nerve conduction velocity) may be slowed or absent, and EMG (electromyography) shows loss of vitality changes.

bubble_chart Treatment Measures

1. Actively treat primary diseases (such as diabetes, uremia, etc.), improve nutrition to correct vitamin deficiencies, and avoid exposure to harmful metals and drugs.

2. Symptomatic treatment:

Use neurotrophic drugs: Vitamin B12, B1, B6, Citicoline, Coenzyme Q10, Nerve Growth Factor, etc.
