The frequency of otitis media among 22 hyperactive children with learning disorders was compared with the frequency of otitis media in a sample of 772 normal children, using the same criteria for the diagnosis of otitis media in both groups. The groups were matched for social class and age when studied (7 to 13 yr. of age). A significantly higher percentage of hyperactive children (54%) had more than 6 episodes of otitis media than was found in the normal group (15%). Thirty-six % of hyperactive children had more than 10 episodes compared to 5% in the normal sample. There was no difference in the percentage of children with no episodes of otitis media (18%). Several alternative hypotheses are offered as possible mechanisms to account for these data.

Mothers of 20 children with learning disorders completed questionnaires concerning the histories and current problems of their children. All the children had average or above average IQs, but below average academic achievement. Compared with a control group of 20 mothers matched for years of education, the mothers of children with learning disorders made significantly more spelling errors per 100 words. The differences in number of spelling errors between learing disorders and control groups were greater for mothers with 12 or fewer years of education than for mothers with more than 12 yr. of education.
