Forty-nine cases of psychogenic deafness in children were observed from 1998 to 1999 at our institute. The patients consisted of 8 boys and 41 girls. As is generally known, psychogenic deafness is caused by exogenous and endogenous factors. In order to investigate the endogenous factors, a psychological test was given to 29 of the 49 children.
The intelligence quotient (IQ) of the children was obtained by WISC (Wechsler intelligence scale for children). The number of children with an IQ over 76 was 20. Of these 20 children,13 had learning disorders. It was thought that the endogenous factors in these deaf children were retardation of school study and poor adaptation to their living environments.
As to their audiological courses, the hearing level of children with learning disorders did not improve except for one child. For these children, it is necessary for us to consider their school study and their parents' expectations of their school records.
