Abstract:
We investigated the incidence of cerebral palsy (CP) in Himeji City with a total population of about 470,000. In 1983-87 the total number of CP patients and the incidence of CP per 1,000 live births were 40 and 1.4, respectively. In 1988-92, the figures were 51 and 2.0. Periventricular leukomalacia was indicated in MRI in 11 out of 40 cases (27.5%) in 1983-87, and in 25 out of 51 (49.0%) in 1988-92. These results suggest that the increase in the incidence of CP mainly depends on changes of medical care for neonates.
