In a prospective study, we examined whether it is possible to diagnose language disorders in children in their second and third years. Twenty patients aged 17-35 months (average 26 months) were examined from August 2002 to June 2004. Language development was tested on the basis of a questionnaire for parents (ELFRA-1 or ELFRA-2) and on a detailed language assessment. After 3-8 months, the children's language was examined again by the same speech pathologist. In 12 children, in whom we had suspected a language disorder, the diagnosis was confirmed. Eight patients showed age-appropriate language development, which was confirmed in six patients at follow-up. In two cases, the follow-up revealed a language disorder. On the basis of a parent questionnaire and examination by a speech therapist, language disorders can be diagnosed in the second and third years of life. However, control assessments are necessary in order to reveal language development disturbances beginning at later ages.
