A 3-year-old child speaks incoherently and often hits people.

Patient's question:

3 years old and still not able to speak

Doctor's answer:

Schizophrenia typically onset in adolescence or early adulthood, characterized by impairments in perception, thinking, emotion, and volitional behavior. The mental activity is not coordinated with the surrounding environment and internal experiences, leading to a disconnection from reality. Generally, there is no significant disturbance in consciousness or obvious intellectual impairment, but there may be cognitive deficits in attention, working memory, abstract thinking, and information integration. The most effective treatment measure is electroconvulsive therapy (ECT). You can consider trying it.
