CASE PRESENTATION A 5-year-4-month-old girl presented with incoordination, drooling, and speech problems (see video, Case 33 ). She was the product of a normal term pregnancy and had weighed 6 pounds 15 ounces. Developmental milestones were delayed. She sat at 10 months and walked at 20 months. At 24 months, she had increasing falls. She was talking and had been toilet trained by 36 months. At age 4 years, she was noticed to have decreased use of her left arm with a mild left hemiparesis, and was diagnosed with cerebral palsy. Drooling was a long-standing problem which had worsened over the 9 months prior to presentation. A head computed tomography (CT) scan and electroencephalogram (EEG) at age 4 years were normal.
