Hallucinations in children with conduct and emotional disorders: I. The clinical phenomena

In a retrospective study, children referred to the Maudsley Hospital with conduct or emotional disorders who also suffered from hallucinations were found to be older than other children seen with similar diagnoses, more of them had below-average IQs and they were more frequently admitted as in-patients. In most cases hallucinations were auditory. When compared with a group of 20 controls matched on these differentiating features, the 20 children with hallucinations had more precipitants of illness, a shorter duration of the disorder, symptoms of depression, and a family history of mood changes. They also had more symptoms suggestive of cognitive-perceptual dysfunction.
