Summary
Periodic familial ataxia is a rare neurological disorder causing sudden, brief episodes of ataxia. This case highlights a patient experiencing these episodes, which resolved after acetazolamide treatment, suggesting its therapeutic potential.
Area of Science:
- Neurology
- Genetics
- Clinical Medicine
Background:
- Periodic familial ataxia (PFA) is a rare autosomal dominant disorder.
- Characterized by recurrent episodes of ataxia, dysarthria, and nystagmus.
- Episodes are often triggered by stress, fatigue, or minor illnesses.
Observation:
- A 34-year-old male presented with a history of three episodes of gait instability, trunk and limb ataxia, and spontaneous nystagmus.
- Episodes were associated with fatigue and stress, lasting 4-6 days.
- Neurological examinations between episodes were normal.
Findings:
- The patient's clinical, laboratory, and neuroradiological data were characteristic of periodic familial ataxia.
- Unlike previous descriptions, no family history of the condition was identified in this case.
- Following treatment with acetazolamide, the patient experienced no further crises.
Implications:
- Acetazolamide appears to be an effective treatment for periodic familial ataxia.
- This case broadens the understanding of PFA, particularly regarding the absence of a family history.
- Further research is warranted to explore the genetic basis and long-term efficacy of acetazolamide in PFA.
