What are the signs and symptoms of dancing eyes-dancing feet syndrome?

Signs and symptoms of dancing eyes-dancing feet syndrome may include an unsteady, trembling gait; myoclonus (brief, shock-like muscle spasms); and opsoclonus (irregular, rapid eye movements).[1] Myoclonus occurs most when trying to move and worsens with agitation or stimulation, but can also be present at rest. An affected person may appear tremulous, or have jerking movements. The face, eyelids, limbs, fingers, head and trunk may be involved. During the peak of the illness, sitting or standing is difficult or impossible.[2] Other symptoms may include difficulty speaking; poorly articulated speech or an inability to speak; difficulty eating or sleeping; excessive drooling; rage attacks; head tilt; a decrease in muscle tone; malaise; and/or other abnormalities.[1][2] Children may appear to be nervous, irritable or lethargic while adults may have mental clouding (encephalopathy).[2]

The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature.

The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined.

Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
