Diagnostic criteria for schizophrenia in the Chinese Classification and Diagnostic Disorders, 3rd edition (CCMD-3)
Diagnostic criteria: This disorder is a group of psychiatric disorders of unknown etiology, most often starting in young adults, often with a slow onset, with multiple disorders of thinking, emotion, behavior, and uncoordinated mental activities. Some patients may develop cognitive impairment in the course of the disease. The natural course of the disease is prolonged, with repeated exacerbations or deterioration, but some patients can remain cured or basically cured.
