Clinical observations were made on 43 prschool children with hearing and speech disorders in Iba- raki Prefecture, from the records in Tokyo Uni- versity Hospital and Ibarki Central Hospital. 1) Twenty-seven were male and sixteen were female. 2) Social and intelligence quatient of these children were measured by using non-verbal perfo- rmance test. The percentage of normally developed children was 70% and that of slightly retarded was 18% and that of severely impaired was 11%. 3) The grade of hearing impairment was de- termined by using conditioning orientation reflex, startle reflex, play audiometry and objective EEG audiometry. The children with hearing loss of 30 to 50dB were 20% of total children suffering from hearing and speech disorders and those of 40 to 80dB were 42% and the severely impaired were 28%. By early education for those partially deaf young children wearing hearing aid whose hearing loss was ranging from 40 to 80dB, we had, good result with cooperation with teachers in deaf scho- ol, case workers, psychologists and their parents. 4) Early diagnosis must be made by speciali- st, at least before 3 years of age. For early diagn- osis, the Health Center should carry out physical check-upsrfor 3 years old children according to the Child Welfare Law.
