Recurrent Hashimoto's Encephalopathy, Showing Spontaneous Remission: A Case Report

Abstract

Hashimoto's encephalopathy (HE) is a rare condition associated with Hashimoto's thyroiditis (HT). It is characterized by neurological/psychiatric symptoms, high levels of anti-thyroid antibodies, non-specific radiological examinations or electroencephalogram abnormalities, and responsiveness to corticosteroid treatment. We describe the case of a man with HE who showed decreased mentality, cognitive impairment, dysarthria, and gait disturbance. The initial attack was improved rapidly by corticosteroid treatment. When the symptoms recurred in 7 months, the patient achieved spontaneous remission without corticosteroid treatment. The recognition of the condition was essential for the prognosis and treatment of this rare disease.

Hashimoto encephalopathy associated with hyperthyroidism: A case report

“…Although the role of thyroid autoantibodies is unclear, HE is a type of autoimmune encephalopathy. The majority of patients respond to treatment with steroids, while certain patients undergo spontaneous remission without steroid administration (9) and other patients fail to improve with steroid treatment (10). Although HE is a rare disease, the condition typically represents autoimmune encephalopathy.…”
