Abbreviations ACPR Australian Cerebral Palsy Register HIC high-income country LMIC low- and middle-income country SCPE Surveillance of Cerebral Palsy in Europe Cerebral palsy (CP) is an umbrella term for a group of disorders of movement and posture, caused by a non-progressive interference in the developing brain. A total of 17 regions were included in the analysis for both pre-/perinatal CP, postneonatal CP, and overall CP, all of which were HICs and from CP registers. • Birth prevalence of pre-/perinatal cerebral palsy (CP) in high-income countries (HICs) is decreasing. Timing of CP was categorized as follows: (1) pre- or perinatal CP - brain injury/maldevelopment during the pre-, peri-, or neonatal period up to 28 days of life, or unknown aetiology; (2) postneonatal CP - a known brain-damaging event unrelated to factors in the ante-, peri-, or neonatal periods, sustained after the neonatal period (28 days of life) but before the age of 2 years; or (3) overall CP - all pre- or perinatal CP and postneonatal CP.
