Insights
Hirayama disease, a rare neurological disorder, affects young individuals with limb weakness. Early diagnosis and cervical collar use can halt the progression of this condition in children.
Area of Science:
- Neurology
- Pediatrics
- Clinical Medicine
Background:
- Hirayama disease presents with asymmetrical distal upper limb weakness and atrophy.
- Onset typically occurs in adolescence or early adulthood.
Purpose of the Study:
- To review the clinical features of Hirayama disease in children (onset before 18 years) in mainland China.
- To identify diagnostic and therapeutic insights for early-stage intervention.
Main Methods:
- Retrospective study of 65 children diagnosed with Hirayama disease.
- Clinical feature review, electrophysiology studies, and flexion cervical MRI.
Main Results:
- Mean age of onset was 15.7 years.
- Electrophysiology revealed C7-T1 denervation; MRI showed posterior dural sac shifting and epidural venous plexus engorgement.
- Cervical collar intervention led to disease progression arrest.
Conclusions:
- Hirayama disease in Chinese children shares features with adult cases.
- Early diagnosis and cervical collar treatment are crucial for managing the condition.
- Increased awareness can improve early detection and intervention.
Abstract:
Hirayama disease is characterized by asymmetrical focal weakness and atrophy of the distal upper limbs with onset in the teens and early 20s. This retrospective study aims to review clinical features of the children (onset before the age of 18 years) with Hirayama disease from mainland of China. Sixty-five children who fulfilled the clinical criteria for Hirayama disease were enrolled. The mean age of onset was 15.7 years, 3.3 years later than the peak age for the normal growth curve. Electrophysiology studies showed chronic denervation changes in C7-T1 segments with normal sensory nerve conduction. Flexion cervical magnetic resonance imaging (MRI) showed forward shifting of the posterior dural sac and engorgement of the posterior epidural venous plexus. Therapeutic intervention with cervical collar can induce a premature arrest of disease progression. Knowledge and awareness of Hirayama disease will facilitate diagnosis and therapeutic intervention in its early stages.
