Latest developments in ataxias
Summary. This article reviews the advances made in the field of ataxias over the past four years. It concludes that there is no single spectacular finding like those that have taken place in the last 25 years and they can all be attributed to the remarkable evolution of genetics and neuroimaging. Nevertheless, algorithms have been perfected that allow a more rational use of the previous techniques to reach a correct diagnosis and possible treatment. With regard to the treatments proposed to alleviate the symptoms of ataxias, there is no unquestionable evidence leading us to think that the symptoms can be reverted with the means currently available, except for a few treatable ataxias, which were already known before that time.
