Seven years have passed since the release of the third edition. The rapidly expanding knowledge in the diagnosis and evidence-based treatment of cerebral palsy (CP)-a condition resulting from fetal and early infant brain damage, characterized by lifelong disabilities with diverse clinical presentations-has encouraged a comprehensive update to the previous edition. This new edition is enriched by the addition of chapters on antenatal factors, genetics, ultrasound, comorbidities, and long-term prognosis. It places special emphasis on the neurodevelopmental examination of the newborn, epilepsy in children and adults with CP, the transition of young adults with CP, and orthopedic care for adults with the condition. Contributions from new distinguished authors worldwide, alongside many contributors from the third edition, have brought sharper insights and enhanced perspectives to this updated version of the book.
