Usage Examples
- Noun:
- The diagnosis was hereditary cerebellar ataxia, explaining the patient's worsening balance and speech.
- Research into hereditary cerebellar ataxia aims to find treatments that can slow its progression.
Advanced Usage
- Clinical context: The term is used precisely in medical genetics and neurology to classify a specific type of inherited ataxia.
- The family history was significant for hereditary cerebellar ataxia across three generations.
