Your child's doctor will review a detailed medical and developmental history and a history of the pregnancy and delivery, including medications taken by the mother, infections and fetal movement. A detailed family history, including the mother's history of miscarriage and whether relatives had similar conditions, also can help.
Your child's doctor will examine your child and may order vision and hearing tests. Additional tests may be done, such as brain imaging with ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI); a test of brain activity using electroencephalogram (EEG); or blood or urine tests.
To help make a specific diagnosis and choose an appropriate therapy plan, the doctor may consult with other specialists, such as a neurologist; an orthopedic surgeon; or an ear, nose and throat doctor (otolaryngologist).
