brief psychotic disorder, schizophrenia, delusional disorder, catatonia
Psychosis is a disorder in perceptions and thoughts that cause a person to lose touch with reality. Most often appearing in the late teens through the 20s, schizophrenia results in hallucinations, delusions, and disordered thinking and behaviors.
Childhood schizophrenia is a severe brain disorder in which children interpret reality abnormally. Signs and symptoms may vary, but they reflect an impaired ability to function. It occurs early in life and has a profound impact on a child's behavior and development. It requires lifelong treatment. The earliest indications of childhood schizophrenia may include developmental problems, such as language delays, late or unusual crawling, late walking and other abnormal motor behaviors like, rocking or arm flapping.
