Glutamic acid decarboxylase antibodies can rarely be associated with various neurological syndromes, which are usually present in adults. Here, we present 2 affected children. Our first patient had a diagnosis of epilepsy and presented with continuous involuntary movements and multifocal myoclonic seizures following an infection at the age of 9. months. Anti-glutamic acid decarboxylase antibodies were found in the serum and cerebrospinal fluid. A partial response was obtained from intravenous immunoglobulin, steroid, and plasmapheresis treatment. The other patient presented with a clinical picture of acute cerebellar ataxia and mutism at the age of 6. years and recovered fully following intravenous immunoglobulin treatment. Neurological findings due to anti-glutamic acid decarboxylase antibodies may be more common in children than previously thought, and achieving an early diagnosis can be important for prompt treatment. © 2012 Elsevier Inc.
