Unilateral spinal muscular atrophy. A case report
Clinical Neurology and Neurosurgery
|January 1, 1983
Summary
This case study describes a 36-year-old man with unilateral spinal muscular atrophy affecting his right limbs since age 26. The condition has remained stable for six years.
Area of Science:
- Neurology
- Genetics
- Clinical Medicine
Background:
- Spinal muscular atrophy (SMA) is a rare genetic neuromuscular disorder.
- Typically, SMA affects both sides of the body symmetrically.
Observation:
- A 36-year-old male presented with muscular atrophy.
- The atrophy was localized to the right upper and lower limbs.
- Symptom onset occurred at age 26, with a 6-year period of stability.
Findings:
- Diagnosis of unilateral spinal muscular atrophy was established.
- This represents an atypical presentation of SMA, affecting only one side.
Implications:
- Highlights the importance of considering asymmetrical presentations in neuromuscular disorders.
- May inform diagnostic criteria and genetic counseling for rare SMA variants.
- Further research into the genetic and molecular basis of unilateral SMA is warranted.
