OCD is the patient knows that it is not right to do or think this way, it is not necessary, but can not control to do, do not do very uncomfortable, after doing some relaxed, but after a while have to do so. For example, patients feel that their bodies are very dirty and they have to wash their hands repeatedly for a long time, and some patients even break their hands. Obsessive-compulsive symptoms are divided into compulsive ideas and compulsive behaviors. Obsessive-compulsive behavior includes obsessive-compulsive cleaning, obsessive-compulsive checking, obsessive-compulsive counting, etc. OCD is related to the living environment, such as the SARS period, every time after touching something to wash their hands, over time, a bit to the direction of compulsive cleaning. Many OCD patients have a background of long-term exposure to unclean things. But why are more people who are also exposed to unclean things not OCD? It also has to do with personality. Those who are perfect, meticulous, and follow the rules are prone to OCD. In the social sense these times are positive words, because the pursuit of perfection, meticulous, serious and serious in order to do things better, many successful people are so. But pay attention to two points: 1, anything should not be excessive, excessive to the opposite. 2, in many ways, the requirements of society and mental health requirements of people on the contrary, social progress requires people to work hard to get ahead to win, to face to face, but too much attention to these people live too tired, psychological stress prone to psychological problems. Patients suffering from obsessive-compulsive disorder understand very well, in psychiatric terminology called self-awareness, that is, they know they have a disease, want to change the status quo and demand treatment. It is because of this understanding and the difficulty in changing that they suffer. Many patients with schizophrenia do not think they have a disease, so they do not suffer, but their family members do. Among psychiatric disorders, OCD is more difficult to treat. The main treatment is medication combined with psychotherapy. Medication is partly antidepressants: fluvoxamine, paroxetine, sertraline, fluoxetine, etc. Psychotherapy is mainly behavioral therapy – aversion therapy. The so-called aversion therapy is painful stimuli to establish a connection with undesirable behavior in order to eliminate this undesirable behavior. For example, when the patient has the urge to compulsively clean, let the patient pop the rubber band set on the patient’s wrist to make it painful. Over time, this compulsive urge to clean establishes a link with the painful stimulus to reduce or eliminate this compulsive urge.
