Early symptoms of schizophrenia are varied and generally relate to the type of onset. The onset can be chronic, subacute, or acute. Chronic onset is most common in clinical practice. Early symptoms of personality change are most common in patients. The patient’s mental activity gradually becomes sluggish, cold to people, distant, avoiding relatives and hostile; or few words, sitting alone, or aimless wandering, lazy life, non-compliance with discipline, ignoring the advice of the surrounding people. Some patients show abnormal personality: they lose their temper for no reason, cannot control themselves, are sensitive and suspicious; or indulge in some fantasies that are out of reality; talk and laugh to themselves; or have unwarranted fear. Some patients experience various uncomfortable feelings: insomnia, headache, easy fatigue, lack of concentration, emotional instability, lack of enthusiasm for work, and reduced ability to study and work. Some patients experience obsessive-compulsive states: fear of getting dirty, fear of getting sick, fear of saying the wrong thing, fear of people looking at them or unexplained fear, or manifesting as stereotypical actions. Early symptoms in some patients are depersonalization, where the patient feels that his or her body type has changed, and in some cases, suspicion of illness. Patients with an acute onset of the disease usually develop within two weeks. Patients suddenly become excited and agitated, impulsive and destructive, acting out, fearful, confused, or joyful for no apparent reason. Early symptoms are difficult to detect before the onset of the illness or may not be present at all. How do I recognize the early symptoms of schizophrenia?
