In recent years, the disease concept of autoimmune cerebellar ataxia has expanded with the identification of anti–neural antibodies. Autoimmune cerebellar ataxia (ACA) is a group of diseases for which pathophysiological elucidation and therapeutic strategies are expected to be established in the future. Although proposed diagnostic criteria for ACA was published from Europe in 2022, the number of patients with ACA and its pathophysiology are still unknown in Japan. That is why early diagnosis and classification of ACA is difficult, which often leads to difficulties in treatment. It is important to establish diagnostic criteria of ACA in Japan.
