Opsoclonus myoclonus syndrome synonyms

Opsoclonus myoclonus syndrome is a rare neurological disorder that primarily affects children. It is characterized by the presence of rapid, involuntary eye movements (opsoclonus) and sudden, brief muscle contractions (myoclonus). This condition is also known by several other names, including:

• Dancing eyes-dancing feet syndrome: This term describes the characteristic eye movements (dancing eyes) and the unsteady gait (dancing feet) often observed in individuals with opsoclonus myoclonus syndrome.


• Kinsbourne syndrome: Named after the neurologist who first described it, Kinsbourne syndrome refers to the combination of opsoclonus and myoclonus seen in this disorder.


• Neuroblastoma-associated opsoclonus myoclonus syndrome: This name is used when the condition is associated with neuroblastoma, a type of cancer that typically affects young children.


• Ataxia-telangiectasia variant: Opsoclonus myoclonus syndrome can sometimes be mistaken for ataxia-telangiectasia, a genetic disorder that affects coordination and immune system function.

Opsoclonus myoclonus syndrome can have a sudden onset and may be accompanied by other symptoms such as irritability, sleep disturbances, and cognitive difficulties. The exact cause of this syndrome is still unknown, but it is believed to involve an autoimmune response triggered by an underlying infection or tumor. Treatment typically involves a combination of immunotherapy, such as corticosteroids or intravenous immunoglobulin, and supportive care to manage symptoms and improve quality of life.
