”Dr. Wei, if we had realized that our child was sick, we wouldn’t have just scolded our child for being lazy, for not doing his job, for being spoiled, for being addicted to games, and we wouldn’t have thought that physical punishment could change him. But Dr. Wei, we really can’t find such popular science information to guide us!” A patient’s father, who works in the local health prevention work, said bitterly. This father’s only son was originally a child of good character, but after his first year of high school became lazy, late to school and early to leave, avoided socializing, did not want to go to school, did not leave home, just played games, was prone to temper tantrums, and since his second year of high school became more dazed, talked to himself, laughed at himself, and was fearful, claiming to be watched, controlled, and victimized. Early symptoms creep in before schizophrenia clearly meets diagnostic criteria. The University of Cologne in Germany, the University of Melbourne in Australia and Yale University in the United States have teams dedicated to studying what the danger sign symptoms include before the onset of schizophrenia. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), published last year, includes “mild psychotic syndrome” as a mental state to be studied. This issue has gained the attention of mental health practitioners in various countries. Risk signs that precede the onset of schizophrenia include: poor interpersonal, school, and work skills; hearing voices or noises and not being sure if they are really heard; excessive paranoia, such as feeling that other people’s ideas are a prank or a trap; becoming disengaged and withdrawn; feeling as if something is wrong; or something else that changes the way one lives. The above manifestations may not be true symptoms of schizophrenia, but if this time is properly assessed and the right intervention is made, a full-blown episode of schizophrenia may be prevented.
