BACKGROUND: About 17% of all @entity1 suffer from a @entity146 in early childhood, defined as the period up to the age of 6 years. METHODS: This review is based on publications retrieved by a selective search in PubMed and the Web of Science, as well as on the authors' clinical and scientific experience. RESULTS: In @entity1 up to age 2, @entity1957 are common (ca. 7%), as are feeding problems (25%), which persist in 2% of @entity1 to meet the diagnostic criteria for a feeding disorder. @entity10273 , a serious @entity1032 , has a prevalence of about 1%: it is more common among @entity1 in situations of increased risk, e.g., orphanages and foster homes. Preschool @entity1 can develop @entity148 and @entity308 , as well as @entity2915 and @entity146 (the latter two mainly in @entity1 ). Parent training and parent- @entity1 psychotherapy have been found to be effective treatments. There is no evidence that psychotropic drugs are effective in early childhood. CONCLUSION: The diagnostician should act cautiously when assigning psychopathological significance to symptoms arising in early childhood but should still be able to recognize @entity146 early from the way they are embedded in the @entity1 's interactive relationships with parents or significant others, and then to initiate the appropriate treatment. Psychotherapy in this age group is still in need of validation by efficacy studies and longitudinal studies of adequate quality.
