Segmental motor paralysis in herpes zoster
Clinical and Experimental Neurology
|January 1, 1984
Summary
Herpes zoster can cause uncommon limb weakness by affecting motor neurons. This condition, often severe, typically shows good recovery and involves anterior horn cells or nerve roots.
Area of Science:
- Neurology
- Infectious Diseases
- Virology
Background:
- Herpes zoster (shingles) can lead to motor complications.
- Ramsay Hunt syndrome (facial palsy) is a known example.
- Segmental lower motor neuron weakness in limbs is rare.
Purpose of the Study:
- To describe cases of herpes zoster-associated limb weakness.
- To analyze the clinical presentation and outcomes.
- To understand the underlying pathophysiology.
Main Methods:
- Case series describing nine patients with limb weakness.
- Clinical examination focusing on motor function, reflex impairment, and neurological signs.
- Analysis of symptom distribution and recovery patterns.
Main Results:
- Nine cases of segmental lower motor neuron weakness in the limbs were identified.
- Weakness was often severe, with muscle wasting and reflex loss.
- Cervical segments were more frequently affected than lumbosacral.
- Long tract signs were absent in all cases.
- Prognosis for recovery was generally good.
Conclusions:
- Herpes zoster can cause segmental limb weakness via anterior horn cell or nerve root involvement.
- The weakness corresponds to sensory dermatome levels or adjacent segments.
- This neurological complication of herpes zoster usually resolves favorably.
