Abstract Mkid 81

We report for the first time in the medical literature three patients with sleepwalking associated with severe hyperthyroidism. Their sleepwalkings were reversed with antithyroid therapy. The authors argue for the presence of symptomatic subgroup of treatable sleepwalkers with hyperthyroidism characterized by the lack past history of sleepwalking, night terrors or other parasomnia, and by the absence of a family history of sleepwalking.
