In the Fujimoto otolaryngology clinic, audiologists have trained the 9 deaf-born children wearing cochlear implants for 3 years and 3 months on the average, mainly used 'auditoryverbal method'. And we followed and investigated their development of the abilities of speech,hearing, articulation, vocabulary, intelligence (measured by Tanaka-Binet test, and Wechsler scale), reading of the sentences, from the age of 30 months to 8 years and 6 months through the training. We classified them into 4 types; (group A)2 cases of deaf-single children started wearing cochlear implants in age of 2 on the average,(group B)3 cases of deaf children with ADHD started wearing cochlear implants in age of 2 and 1 month on the average, (group C)3 cases of deaf-single children started wearing cochlear implants in age of 6 on the average,(group D)1 case of deaf child with ADHD started wearing cochlear implants in age of 6. And we investigated the effect of the age of started wearing cochlear implant and ADHD on the development of speechlanguage and cognitive neuropsychological abilities. The results were as follows; 1) Group A could catch up with all abilities of their calendar ages in early time, almost 3 years, and also their development after that continued good level. 2) Secondly, group B also could show good improvement level in early age after group A.3) And the next improvement level was group C, and after that was group D.4) It suggested that wearing cochlear implant before 2 years and wearing cochlear implant for the deafchildren with ADHD could effect on the developmental improvement of the speechlanguage and cognitive neuropsychological abilities.
