Hashimoto's thyroiditis--a rare but treatable cause of encephalopathy in children

Abstract

Hashimoto's encephalopathy is a very rare complication of Hashimoto's thyroiditis. It is a progressive or relapsing encephalopathy associated with elevation of thyroid specific autoantibodies. Patients usually present when euthyroid and this diagnosis should be considered in any unexplained encephalopathy or progressive cognitive decline in the euthyroid patient.
