Which of the following statements about childhood-onset schizophrenia is correct?

Choice A reason: Disorganized speech in early childhood is not specific to schizophrenia and may be seen in developmental disorders such as autism spectrum disorder or language delay. It is not a reliable early indicator of schizophrenia. Choice B reason: Childhood-onset schizophrenia is associated with poorer outcomes compared to adult-onset due to earlier disruption of cognitive and social development. Early intervention may help but does not necessarily lead to better prognosis. Choice C reason: Childhood-onset schizophrenia shares many features with adult-onset, including a gradual onset and the presence of negative symptoms such as social withdrawal, flat affect, and cognitive deficits. These symptoms often precede psychotic features and are more prominent in early-onset cases. Choice D reason: Schizophrenia is rare in children, and other diagnoses such as mood disorders, autism spectrum disorder, or trauma-related conditions should be considered first. It should not be the initial diagnosis without thorough evaluation.
