Opsoclonus myoclonus is a rare neurological disorder characterized by an unsteady, trembling gait, myoclonus (brief, shock-like
muscle spasms), and opsoclonus (irregular, rapid eye movements). Other symptoms may include difficulty speaking, poorly articulated
speech, or an inability to speak. A decrease in muscle tone, lethargy, irritability, and malaise (a vague feeling of bodily
discomfort) may also be present. Opsoclonus myoclonus may occur in association with tumors or viral infections. It is often
seen in children with tumors.
Is there any treatment?
Treatment for opsoclonus myoclonus may include corticosteroids or ACTH (adrenocorticotropic hormone). In cases where there
is a tumor present, treatment such as chemotherapy, surgery, or radiation may be required.
What is the prognosis?
The prognosis for opsoclonus myoclonus varies depending on the symptoms and the presence and treatment of tumors. With treatment
of the underlying cause of the disorder, there may be an improvement of symptoms. The symptoms sometimes recur without warning.
Generally the disorder is not fatal.
What research is being done?
The NINDS supports and conducts research on movement disorders such as opsoclonus myoclonus. These studies are aimed at increasing
knowledge about these disorders and finding ways to prevent, treat, and cure them.
