Twenty children with meningitis diagnosed in the Hospital das Clinicas da Faculdade de Medicina de Ribeirão Preto between 1963 and 1967 were available for prospective study; each was submited to neurological and electroencephalographyc examination, D.Q. (Gesell) and I.Q. (Raven) tests. Patients were followed from 6 months to 3 years after the acute phase of the disease. There is statistically significant difference between the D.Q. of post-meningitic children and the D.Q. of non meningitic controls of same social class and ages, when the onset of illness was before 30 months of age. No statistically significant correlation was found between the D.Q. and the patient's lenght of hospitalization or the first cerebrospinal fluid protein level. There is a possibility that significant correlation betwenn the D.Q. and age at onset of illness may be observed by studying a larger number of patients. No statistically significant difference was found between the l.Q. of postmeningitic children and controls when the onset of illness was after age 4.
