Management of Cerebellar Ataxia
Diagnostic Considerations
- The American College of Radiology recommends MRI of the head without IV contrast as the preferred initial imaging modality for evaluating cerebellar ataxia to detect morphologic changes and signal alterations in the cerebellum and brainstem 3
- If inflammatory or neoplastic causes are suspected, contrast-enhanced MRI should be included in the evaluation 3
- Advanced MRI techniques such as diffusion-weighted imaging and spectroscopy may help detect early changes and distinguish between ataxia subtypes 3
- Cerebellar ataxia is characterized by unsteadiness that does not significantly worsen with eye closure, distinguishing it from sensory ataxia 4
Rehabilitation Interventions
Physical Therapy
- The American Heart Association recommends balance training programs for individuals with poor balance, low balance confidence, and fear of falls 1
- Postural training can improve trunk control and should be considered for rehabilitation of ataxia 1
- Task-oriented upper limb training can improve reaching speed and reduce trunk motion during reaching in patients with upper limb ataxia 1
- Progression to more challenging training activities over the course of rehabilitation is important for continued improvement 1
Assistive Devices and Orthotics
- Individuals with cerebellar ataxia should be prescribed and fitted with appropriate assistive devices or orthoses to improve balance and mobility 1
- Canes and ankle-foot orthoses (AFOs) can significantly improve balance in patients with cerebellar ataxia 1
Speech and Swallowing Therapy
- Dysphagic problems commonly emerge as the disease progresses, requiring evaluation and management by the European Respiratory Society 5
- Videofluoroscopic swallow study (VFSS) is the gold standard for assessing potential abnormalities of the pharyngeal phase of swallowing 5
- Patients with cerebellar ataxia often have problems with thin consistencies, which should be addressed in swallowing therapy 5
Management of Associated Symptoms
- Dyscoordinate swallowing and chronic aspiration require careful assessment and management to prevent lung disease, as recommended by the European Respiratory Society 5
- Nutritional assessment and intervention are crucial as malnutrition is a significant comorbidity in patients with cerebellar ataxia 5
- Gastrostomy may be required to improve nutrition, reduce aspiration-related risks, and improve quality of life related to mealtimes 5
Multidisciplinary Approach
- Regular monitoring and proactive treatment of various aspects of cerebellar ataxia under multidisciplinary expertise is recommended by the European Respiratory Society 6
