Major advances in our understanding of the neurology/pathology, anatomy/physiology, and molecular biology of the cerebellum have opened a new door for cerebellar ataxias (CAs). We have now entered in the ‘era of therapies’. Cures are knocking at the door. We discuss the hot topics in the therapeutic protocols available for CAs, including aminopyridines, noninvasive cerebellar stimulation, anti-oxidant drugs and therapies for immune-mediated cerbellar ataxias (IMCAs), topics emphasized in this issue. The history of the cerebellum is a typical example of the importance of apparently divergent and multi-disciplinary approaches.
