Hashimoto's encephalopathy——case report and literature review / 中华内分泌代谢杂志

ABSTRACT

Hashimoto's encephalopathy(steroid-responsive encephalopathy associated with autoimmune thyroiditis,SREAT)is a rare disorder,accompanied by seizures,tremor,myoclonus,ataxia,psychosis,and stroke-like episodes,breaking out with an acute or subacute onset and having a relapsing/remitting or progressive course which is not correlated to thyroid hormone levels.Patients with Hashimoto's encephalopathy are usually euthyroid or dysthyroid with positive antithyroid antibodies,have a moderately raised cerebrospinal fluid protein content,and have a global slowing of the electroencephalogram and a normal or near normal imaging except in rare cases.The pathogenesis of Hashimoto's encephalopathy is still obscure.This paper reports a case diagnosed as"Hashimoto's encephalopathy".It is suggested that the diagnosis of Hashimoto's encephalopathy should be considered in cases with unexplained encephalopathy associated with high levels of antithyroid antibodies despite normal thyroid function.
