Appropriate for gestational age (AGA):Infants whose birthweights are as expected for their gestational age; 10th - 90th percentile is often used.
Arnold Chiari malformation: a malformation that can accompany myelomeningocele and other neural tube disorders where the cerebellum and medulla oblongata protrude into the spinal canal.
Asymmetric IUGR: IUGR that has resulted in weight and length measurements that are less than expected for gestational age, but a "normal" head circumference.
Bronchopulmonary dysplasia (BPD): a chronic lung disorder that is most common among children who were born prematurely, with low birthweights, and who received prolonged mechanical ventilation.
Catch-up growth: a term used to describe a rate of growth that is faster than expected. For infants born with low birthweights or small for gestational age, catch-up growth can describe gains in weight or length where the measurement reaches the 5th percentile for age (when it had previously been below the 5th percentile). In other instances, catch-up growth refers to weight and/or height gains when a child who has experienced stunted growth receives adequate energy and protein.
Cerebral palsy: a motor nerve disorder caused by injury to the central nervous system; symptoms depend on the area of the brain involved and the severity of the damage.
Contractures: static muscle shortening resulting from tonic spasm or fibrosis; frequently seen in individuals with cerebral palsy.
Cornelia deLange syndrome: a congenital syndrome characterized by short stature, microcephaly, delayed development and mental retardation, a number of distinct facial features, and upper limb anomalies; also referred to as deLange syndrome and Brachmann-deLange syndrome.
Corrected age: the age of an infant from birth, less the number of weeks premature.
Early intervention services: established by Part H of P.L. 97-457 of 1986 (now Part C of the IDEA of 1997); community-based therapeutic and educational services for infants and children under 3 years of age with developmental delays.
Encephalopathy: any degenerative disease of the brain.
Gastroesophageal reflux (GER): regurgitation of the contents of the stomach into the esophagus, where they can be aspirated; often results from a failure of the esophageal sphincter to close.
Gestational age: the age of a fetus or newborn, usually stated in weeks from the first day of the mother's last menstrual period.
Hypotonia: diminished muscle tone.
