Dancing eyes-dancing feet syndrome
, also known as opsoclonus myoclonus syndrome (OMS), is a rare neurologic disorder characterized by ocular (eye), behavioral, sleep, and language problems. The onset is usually abrupt, often severe, and can become chronic. OMS typically occurs in association with tumors (neuroblastomas), or following a viral infection. Treatment may include corticosteroids or ACTH (adrenocorticotropic hormone). When there is a tumor present, treatment may include chemotherapy, surgery, and/or radiation. When the underlying cause of OMS is treated, symptoms may improve. Relapses are common and may occur without warning.
