Abstract
-
Hashimoto's encephalopathy is a steroid responsive relapsing disorder associated with high titers of thyroid-related autoantibodies that presents with subacute progressive dementia and myoclonus. Although most patients reported have been either euthyroid or hypothyroid at the time of presentation, we present a patient with Hashimoto's encephalopathy with thyrotoxicosis that was successfully managed with steroids and antihyperthyroid therapy. We recommend that encephalopathy presented in patients with hyperthyroidism should be tested with thyroid-related autoantibodies and managed with steroid and antihyperthyroid therapy.
