[The epidemiology of mental disorders in youth : A narrative review including Austrian data]

For decades, epidemiological studies have consistently and impressively demonstrated the frequency of mental illness in childhood and adolescence. Mental health disorders are among the most common causes of diminished quality of life among young people, sometimes casting long shadows into adulthood. This narrative review looks at this phenomenon using a selection of research findings dealing with overall prevalence figures, with the prevalence of individual disorders, and with the progression of mental illness from childhood and adolescence to adulthood. Austrian epidemiological studies supplementing these findings are also presented.
