Childhood schizophrenia (also known as childhood-onset schizophrenia, and very early-onset schizophrenia) is similar in characteristics of schizophrenia that develops at a later age, but has an onset before the age of 13 years, and is more difficult to diagnose. Schizophrenia is characterized by positive symptoms that can include hallucinations, delusions, and disorganized speech; negative symptoms, such as blunted affect and avolition and apathy, and a number of cognitive impairments. Differential diagnosis is problematic since several other neurodevelopmental disorders, including autism spectrum disorder, language disorder, and attention deficit hyperactivity disorder, also have signs and symptoms similar to childhood-onset schizophrenia.The disorder presents symptoms such as auditory and visual hallucinations, strange thoughts or feelings, and abnormal behavior, profoundly impacting the child's ability to function and sustain normal interpersonal relationships. Delusions are often not systematized and vague. Among the psychotic symptoms seen in childhood schizophrenia non-verbal auditory hallucinations are the most common, and include noises such as shots, knocks, bangs. Other symptoms can include irritability, searching for imaginary objects, or low performance. It typically presents after the age of seven. About 50% of young children diagnosed with schizophrenia experience severe neuropsychiatric symptoms. Studies have demonstrated that diagnostic criteria are similar to those of adult schizophrenia. Neither DSM-5 nor ICD-11 list "childhood schizophrenia" as a separate diagnosis. Diagnosis is based on behavior observed by caretakers and, in some cases depending on age, self reports.
