Case Presentation of Autoimmune Septin‐5 Cerebellar Ataxia.

This article presents a case study of a patient with autoimmune cerebellar ataxia caused by antibodies attacking septin-5, a neural protein involved in neurotransmitter exocytosis. The patient initially experienced COVID-19 pneumonia followed by symptoms of ataxia, diplopia, and dysarthria. The article discusses the patient's medical history, laboratory findings, and treatment course, highlighting the use of immunotherapy. The study suggests that autoimmune cerebellar ataxia may have a prolonged inflammatory course and may respond to a serially escalating course of immunosuppressive treatments.
