The Geelong study.

The Geelong study is a prospective study of common abnormalities of pregnancy and birth and subsequent development. It outlines the prevalence and interrelationships of breath-holding attacks, febrile convulsions and non-febrile convulsions in the first 11 years of life. The interrelationship between febrile and non-febrile convulsions, behaviour and learning at 5 and 11 years is described. The predictive value of assessment at 5 years for later performance and behaviour at 11 years is also discussed.
