Cerebral palsy: survival rates, associated handicaps, and distribution by clinical subtype (Rochester, MN, 1950-1976).

We identified 64 cases of cerebral palsy (CP) born to Rochester residents in 1950-76. The majority (73%) had one of the spastic syndromes. Ataxic and dyskinetic syndromes constituted 16% and 6%, respectively. Survival follow-up was available through 1980 birthdates. Using life-table methods, we calculated survival rates for the first 10 years of life. For severely or profoundly retarded children, survival was 68% at 5 years and 54% at 10 years. All others survived through their 1980 birthday. Follow-up of CP resolution was available through the seventh birthday. Cases born in 1968-76 had the highest resolution rate (30%). For mild CP, the 1968-76 resolution rate was 86%.
