The clinical picture of childhood schizophrenia is fairly constant. Symptom fluidity and psychotic functions coexist with other functions. The essential signs and symptoms are primitive or absent relationships to people, usually an excessive attachment to inanimate objects; impaired or absent reality testing; weak, absent, or bizarre affective responses; mutism or language use for other than the usual human communication; severe disturbances of motility. Other important signs and symptoms run the gamut of psychopathology.
