Acute Cerebellar Ataxia Associated with Modest Elevation of Anti-GAD Antibodies in a Young Patient

  • Juliana Gomez
  • Dongkwan Jin


Background: Anti-GAD-related cerebellar ataxia has rarely been described as an acute cause of autoimmune ataxia.

Phenomenology Shown: A young female who acutely developed anti-GAD-associated ataxia with magnetic resonance imaging (MRI) showing cerebellar edema and follow-up MRI 6 months later showing cerebellar atrophy.

Educational Value: Recognize that anti-GAD-associated cerebellar ataxia can present in a young adult as an acute and severe cause of ataxia, with cerebellar changes evident on MRI.
