Clinical challenges in the ataxias
Ataxias are rare diseases and the etiologic heterogeneity make individual entities even rarer. There are still substantial numbers of patients who are still poorly understood. Available assessment techniques still point to large numbers of patients needed for clinical trials and the need for cooperative efforts, better assessment tools and novel trial designs. Better understanding of neural circuitry abnormalities may lead to more effective symptomatic therapy. Opportunities exist for targeting at risk individuals for effective therapies but how this can be done is not clear. Preventive strategies may become feasible in many ataxias.
