A revision of the characteristics of psychotic symptoms in children and ado
lescents such as hallucinations, delusions and thought disorders is present
ed. Assessment of a psychotic child or adolescent must include a complete p
hysical examination and interviews with family and collaborative sources. D
ifferential diagnoses of psychosis in this age include schizophrenia, mood,
dissociative and pervasive developmental disorders. Psychotic manifestatio
ns in young patients are influenced by developmental stage, and their treat
ment involves interventions in all spheres. Studies with typical and atypic
al antipsychotics for the treatment of different conditions are revisited.
