[Is there a subgroup of hyperkinetic children with emotional disorders? Results of a pilot study].

Child psychiatric classification systems make no provision for a regular association between the Hyperkinetic Syndrome and emotional disorders. However, such an association could be demonstrated in 9.3% of 464 in- and outpatients seen at our child psychiatric unit for treatment of hyperkinesis. Based on the differences found between the subjects with both the Hyperkinetic Syndrome and emotional problems and those without emotional problems, four pathogenetic models were discussed. An experimental design is proposed for hypothesis testing.
