Background:
Cerebellar ataxia, neuropathy and bilateral vestibular areflexia (CANVAS) is a rare neurodegenerative disease affecting the cerebellum, the peripheral nervous system and the vestibular system. Due to the lack of approved drugs, therapy comprises physiotherapy and speech therapy. Transcranial magnetic stimulation is a promising non-invasive therapeutic option to complement classical symptomatic therapies.
Objective:
To test feasibility of the combination of transcranial magnetic stimulation using an accelerated protocol and standard symptomatic therapy in patients with CANVAS.
Methods:
Eight patients with genetically confirmed CANVAS were assigned to either verum or sham cerebellar transcranial magnetic stimulation using an accelerated protocol. Treatment duration was limited to 5 days. Additionally, patients in both groups received symptomatic therapy (speech and physiotherapy) for the duration of the study.
Results:
All patients completed the stimulation protocol. Adverse events were rare. Ataxia severity improved in the verum group only.
Conclusion:
The combination of transcranial magnetic stimulation and classic symptomatic therapy is feasible in a neuro-rehabilitation setting and potentially ameliorates ataxia severity.
