Hashimoto’s Encephalopathy Presenting as Dizziness and Diplopia

Abstract

Hashimoto’s encephalopathy (HE) is an uncommon neurological disorder characterized by subacute encephalopathy with elevated serum levels of thyroid autoantibodies. Due to the absence of specific tests and the diversity of neurological symptoms and signs, the diagnosis of HE is often delayed. We highlight the various manifestations of HE by reporting a patient who presented with atypical neurological signs such as dizziness and diplopia. The diagnosis was delayed until the patient progressed to cognitive impairment and generalized chorea.
