The nosological status and treatment of auditory hallucinations in children who have either emotional or behavioural disorders is an area that is poorly researched. Auditory hallucinations are associated with a wide range of emotional and behavioural disorders, and are likely to be present in between 1% to 5.7% of children seen in out-patient clinics by child and adolescent psychiatrists. A case study of a 12-year-old boy with a 14-month history of second-person auditory hallucinations associated with a diagnosis of severe depression is presented. In terms of age, gender, family history and symptomatology, this case is typical of children with non-organic, non-schizophreniform hallucinations. In this case, successful treatment comprised both cognitive-behavioural techniques, aimed at alleviating the mood disorder, and neuroleptic medication.
