The symptoms of schizophrenia are; babbling, crying and laughing, sensitivity and suspicion, not knowing dirty and clean, indifference and withdrawal …… These are the symptoms of schizophrenic patients at the onset. Adequate recognition of them is an important prerequisite for effective treatment. How can I tell if a person has schizophrenia? To determine whether a person’s mental activity is normal, several comparisons need to be made: the present compared to the past; the person compared to others; whether it conforms to the local customs and norms of the time; whether it conforms to objective reality; whether there are signs of incomprehensible behavior; and whether the entire mental activity is coordinated and unified. If there are significant differences, it is important to consider whether there are abnormalities in mental activity. The final determination of whether one is suffering from schizophrenia also requires seeking a diagnosis at a specialist hospital that is available.
