Recessively inherited 'pure' spastic paraplegia: case study.
Clinical Neurology and Neurosurgery
|January 1, 1982
Summary
This study presents two brothers with pure spastic paraplegia, likely inherited in an autosomal recessive pattern. Neurophysiological tests indicated cuneate tract involvement, highlighting the importance of these evaluations in diagnosing familial spastic paraplegia.
Area of Science:
- Neurology
- Genetics
- Neurophysiology
Background:
- Familial spastic paraplegia (FSP) is a group of inherited neurological disorders.
- Pure spastic paraplegia affects only the corticospinal tracts.
Observation:
- Two brothers presented with pure spastic paraplegia, with onset in the first decade.
- Autosomal recessive inheritance was suspected.
- Standard neurophysiological tests including peripheral nerve conduction, visual evoked potentials (VEPs), and brain stem auditory evoked potentials (BAEPs) were normal.
Findings:
- Somatosensory evoked potentials (SSEPs) suggested involvement of the cuneate tract.
- This points to a specific spinal cord pathway affected in this form of FSP.
Implications:
- Neurophysiological evaluation is crucial for diagnosing and understanding the pathophysiology of familial spastic paraplegia.
- Identifying specific tract involvement aids in differential diagnosis and potential therapeutic strategies.
