Opsoclonus-Myoclonus Syndrome Symptom Guide

Acute Cerebellar Ataxia

Acute cerebellar ataxia is a neurological disorder that occurs when the cerebellum is damaged or inflamed. The cerebellum controls muscle coordination and a person's gait. Ataxia occurs when individuals lose the ability to coordinate or control their voluntary muscle movements. In acute cases, ataxia happens quickly, generally showing up within a few minutes to two days. Acute cerebellar ataxia causes a loss of coordination that makes it difficult to perform day-to-day tasks. The condition is most commonly seen in children from two to seven years old. Most opsoclonus-myoclonus syndrome patients are also children. There are multiple symptoms of acute cerebellar ataxia, including impaired coordination in the legs, arms, or torso, along with an unsteady gait and frequent stumbling. Patients may have trouble with eating, writing, buttoning shirts, and other tasks requiring fine motor skills. Slurred speech and vocal changes are also common, and some patients may experience dizziness and headaches.
