Obsessive-compulsive imagery is mostly auditory or visual imagery, which manifests itself as sounds or sights appearing inside the mind, and is not easy to distinguish clinically from the hallucinations of schizophrenia with the following characteristics: 1. Symptoms are spontaneous but involuntary and autonomous, an involuntary presentation. 2. The sounds or sights appear inside the mind. (Note: Schizophrenic hallucinations mostly appear in objective space, usually as realistic as if we were speaking face to face, and seem completely real and convinced to the patient, whose emotions and behaviors are governed and controlled by the hallucinations.)

OCD manifested as recurrent music or singing in the brain is still relatively common, and in the case of sights, they can be static or dynamic. 4, there is a seemingly ever heard the voice, experienced the scene, or saw the scene repeatedly in the mind reproduced, but there is also not so. 5.The content is repetitive, disgusting, angry, or frightening, and can lead to significant anxiety and worry. 6. Symptoms are usually produced or aggravated on certain occasions. Some people have symptoms when they are doing work or studying that they particularly care about, while others have symptoms when they are resting and have nothing else to do; some children have symptoms when they are at school, but not when they go home. Diversion of attention usually leads to a temporary reduction or disappearance of symptoms for a short period of time. 8, may be accompanied by other anxiety or obsessive-compulsive symptoms. 9, the patient to take some measures to neutralize or fight against the symptoms, in order to alleviate anxiety, manifested as compulsive behavior (for example, there is a female patient, working as a nurse in the hospital, postpartum illness, when she repeatedly appeared in her mind the “play” of the patient’s death scene, her hands to make some fork movements to symbolize the elimination of the inauspicious. Without in-depth questioning, it is easy for a doctor to judge this type of behavior as “bizarre behavior” and diagnose the patient with schizophrenia (Yu Jinlong). Some patients also take some measures to avoid symptoms, for example, children refuse to go to school. 10. If the patient is young, the symptoms are often atypical, and it is difficult to accurately describe the obsessive-compulsive imagery because of the young age, then it is easier to be confused with the hallucinations of schizophrenia. Some patients have self-awareness, some have incomplete self-awareness, and some have no self-awareness; some have anti-compulsive behavior, and some do not. 12, although some patients with obsessive-compulsive disorder have strange and bizarre behaviors, their personalities are still integrated, and doctors can feel the patient’s feelings. 13, in terms of etiology, personality traits and social and cultural family and other external factors play a relatively larger role, often with obsessive-compulsive disorder or anxiety disorders more common personality traits, such as neuroticism, the pursuit of perfection. 14, the subconscious meaning behind the obsessive-compulsive symptoms may be more obvious than the hallucinations. 15, antidepressant medication is effective or partially effective, or may not be effective, because the treatment is also affected by a variety of other factors. 16, Psychotherapy or family therapy for obsessive-compulsive imagery is more important than auditory hallucinations in schizophrenia. 17, obsessive-compulsive imagery and schizophrenia pseudo auditory hallucinations in the form of extremely similar, the doctor only combined with the above characteristics to go to a detailed and in-depth examination and observation in order to identify, such as obsessive-compulsive imagery of the content of the repetition and so on.
