Children routinely have intrusions of fan- about whether children are capable of having psychotic tasy into ordinary mental life; determining when this becomes pathologic can be a matter of degree. Children learn and experiment with imitation, and they can acquire habits and strategies used by those around them. Towbin: Complex Developmental Disorders Clinic, De- ner. When one examines a 5-year old child who claims hood psychoses. Nevertheless, there came an acknowledg- that he is 'superman and can fly,' the challenge is to deter- ment and new awareness of major developmental differences mine whether the child has a delusion. Similarly, in a child in the perception of reality (12) and that developmentally who complains about hearing a voice telling her to 'do bad or culturally appropriate beliefs (e.

Such characteristics are sought by the clinician in and delusions were not required criteria (6,13–15). The task and adopted this nosology and grouped all childhood psychoses challenge as child and adolescent psychiatrists are to ask the under childhood schizophrenia. As a result of this broad right questions, to differentiate delusions and hallucinations grouping, the literature regarding childhood schizophrenia from other forms of thought, such as a vivid imagination from this period overlaps with that of autism and does not in a young child. With further development of psychiatric taxonomy and elucida- tion of the phenomenology (course, onset, family history, HISTORY and associated features), the distinctiveness of the various childhood psychoses and the similarity between child and Interest in childhood psychosis can be traced to the nine- adult schizophrenia were demonstrated (16,17). This teenth century, when Maudsley first wrote a description of change had a pronounced influence on the nosology of these the 'insanity of early life' in 1874 in his textbook, Physiology disorders and led eventually to changes with the DSM-III and Pathology of Mind (4). Schizophrenia arising in childhood and infantile au- proach by noting that the mental faculty of children was tism came to be recognized as distinct clinical syndromes, not organized, and hence the insanity in children must be each with its unique and distinct psychopathologic phe- of the simplest kind, influenced more by 'reason of bad nomenology, theories about causes, and longitudinal course. This distinction has had an impact on hood schizophrenia as different from mental deficiency and how children with these disorders are currently evaluated, from certain neurologic disorders, such as epilepsy or postin- managed, and treated. It was not until 1919, that Kraeplin introduced the concept of dementia praecox and noted its onset in late childhood and adolescence (6). Given COGNITIVE ASPECTS the insidious onset of the disorder, Kraeplin cautiously sug- gested that 3. This led to less may complain of changes in their mental and cognitive an increased interest in understanding the developmental states. To these changes, clinicians add signs, based on ob- aspects of psychosis. Historically, despite this early descrip- servations derived from the mental state examination of the tion of the syndrome by Kraeplin that is now recognized children and data obtained from laboratory or cognitive as schizophrenia, other diagnostic terms were put forward as tests. Subsequently, a distinctive pattern may emerge over well. Psychotic symptoms age, and offered specific diagnostic criteria for children (8). Cognitive impairments, particularly im- nia and autism. From a cognitive and developmental standpoint, certain It is critical to avoid rushing to a premature conclusion clinical features in children create diagnostic challenges.

Furthermore, because the onset of childhood cribed to psychosis without the concomitant presence of a schizophrenia is insidious, with a lifelong history of develop- thought disorder. It has also been suggested that the develop- when her disorder had its onset, she noted that the sound ment of psychotic conditions during childhood may have of the train whistle changed, and she began to wonder why.

She be the first signs of dysfunctional premorbid development. Things around her nerability factors, indicative of a risk of psychotic illness started to have special meaning, her thoughts were (22). Recent work has also pointed to early language deficits 'strange,' and she was puzzled and bewildered. Over the next several years, she However, a socially odd child is not usually schizophrenic. She believed that the train whistle was schizophrenic (24–26), because they lack the requisite per- sending special messages from God to her. Intellectual delays have questioned these perceptions and believed them to be real. Distinguishing between the formal thought disorder of schizophrenia and that of developmental disorders, person- ality disorders, and speech and language disorders also pre- sents diagnostic problems (30). Symptoms such as thought CLINICAL AND DEVELOPMENTAL disorder have been noted to arise in persons with pervasive CONSIDERATIONS developmental disorders, particularly those with good lan- guage skills, such as (often referred to as 'high functioning') Developmental factors influence the detection, form, and autistic persons and those with Asperger syndrome (31,32). One problem Although loose associations and incoherence are valid of assessing psychotic disorders in very young children com- diagnostic signs of early-onset schizophrenia, these symp- pared with older children is that these symptoms in young toms are also sometimes seen in schizotypal children (33). Isolated The inclusion criteria of disorganized speech according to hallucinations can occur in acutely anxious but otherwise DSM-IV (34), rather than a formal thought disorder, pre- developmentally intact preschool children.
