Schizophrenia is a common mental disorder of unknown etiology, characterized by disorders of perception, thinking, emotion, volition and behavior, as well as by uncoordinated mental activity and detachment from reality. The onset of schizophrenia is usually in young adulthood, with a slow onset and a prolonged course. Self-awareness is largely lost during the onset. Patients with schizophrenia are often immersed in their own world, talking to themselves, getting angry inexplicably or treating friends and loved ones violently, causing serious harm to the patient and the patient’s family. So, what are the early signs and symptoms of schizophrenia? Very many people have some nervousness from time to time, but that is definitely not a symptom of schizophrenia. Very many schizophrenic patients today do not even know that they are ill, resulting in failure to treat them in a timely manner. Schizophrenia patients show symptoms: Emotional changes: becoming apathetic, losing previous enthusiasm, not caring about loved ones, lacking proper emotional communication, being distant from friends, and not being interested in things around them. Sleep changes: Gradually or suddenly becoming difficult to fall asleep, waking up easily or not sleeping deeply, having nightmares throughout the night, or sleeping excessively. This is a common schizophrenic symptom. Sensitivity and paranoia: Very sensitive to everything, associating ordinary things around him with him and thinking they are directed at him. Always observes what is said and pays attention to every move of others. Abnormal behavior: The behavior gradually becomes strange, secretive or incomprehensible, likes to be alone, uncomfortable chasing after the opposite sex, unashamed, laughing to himself, living a lazy life, dazed and dazed, sleeping in the dark, wandering out, not returning home at night, etc. Personality change: Behavior and behavior become puzzling. Patients generally prefer to be alone, avoid friends and family and are hostile, and live a lazy and undisciplined life. The clinical symptoms of schizophrenia can be eliminated before the patient returns to normal.
