Movement disorders in non-encephalopathic Hashimoto's thyroiditis

Since the seminal report of Lord Brain et al., in 1966 [1], neurologic manifestations of Hashimoto's thyroiditis (HT) have been increasingly recognized, and it is now evident that clinical features are diverse and that the response to steroids is variable [2 –5]. The term “steroid-responsive encephalopathy associated with autoimmune thyroiditis” (SREAT) has been proposed, however, signs of encephalopathy with altered mental state may be absent, as may clinical response to steroids. With respect to movement disorders, these are reported most often in the setting of encephalopathy; myoclonus is the commonest manifestation but dystonia, ataxia, tremor, and rarely chorea, are also described [3–5].
