PURPOSE: Cerebral palsies are the most common and severe motor disabilities in childhood. There is currently increased interest in their occurrence and patterns of likely cause for a variety of reasons. Therefore, a retrospective study was carried out to understand the clinical features of cerebral palsy. METHODS: A retrospective chart review was conducted of all children with cerebral palsy who were diagnosed at St. Benedict Hospital between March 1999 and March 2001. RESULTS: Cerebral palsy patients were classified into 6 major groups. Of six groups, spastic diplegia is the most common type of cerebral palsy(55.3%). The risk factors of cerebral palsy were placenta previa(1 case), placenta abruption(1 case), cytomegalovirus infection(1 case), prematurity (53 cases), neonatal asphyxia(12 cases), dystocia(2 cases), breech delivery(1 case), multiple birth(5 cases), head trauma(3 cases), meningitis(2 cases) and unknown(26 cases). Among the 59 in the preterm group, 37 patients showed MR or CT images of periventricular leukomalacia. Among the 44 in the term group, 15 patients showed MR or CT images of atrophy. Among 103 patients, 29 patients(28.2%) had a seizure disorder. CONCLUSION: It is very importent to understand the clinical features and risk factors of cerebral palsy for physicians to diagnose and manage cerebral palsy patient.
