OCD is a type of anxiety disorder, a group of neuropsychiatric disorders with obsessive-compulsive thinking and compulsive behavior as the main clinical manifestations, characterized by the coexistence of conscious obsessions and counter-compulsions, some meaningless or even against their will thoughts or impulses repeatedly invade the daily life of patients. Although patients experience these thoughts or impulses as originating from themselves and try to resist them, they are always unable to control them, and the strong conflict between the two makes them feel great anxiety and pain, affecting their studies, work, interpersonal interactions and even their daily lives. and make associations. A common symptom is the recurrence of a certain past event, a certain sentence or a certain song in the mind. For example, if you have just locked the door, you suspect that it was not locked; if you have just dropped a letter into the mailbox, you suspect that you did not put a stamp on it; if you have just finished your homework, you suspect that you missed it or did it wrong; if you have just washed your hands, you always feel dirty. 3, compulsive poor thinking: this symptom is similar to the bull’s-eye, the patient will meditate on some meaningless issues, entangled in which can not get out. A female student said during a psychological consultation: “I am under a lot of pressure because of my bad studies, so I always force myself to think through all the knowledge points, and I have to think desperately even if I can’t think. But in recent times, I sometimes think of some strange problems, such as 1 + 1 = 2 why does not equal to 3? The more I thought about it, the more I couldn’t figure it out, so I entered a vicious circle. I was so nervous that I started to resist this kind of thinking, but I got deeper and deeper into it, and I couldn’t even do my normal study.” This is a typical symptom of compulsive exhaustion. The patient’s thinking is like being compelled to pull on a never-ending train with no end in sight, and eventually the body and mind are exhausted. 4. Compulsive intention: The patient repeatedly experiences a strong inner urge to do some kind of action or behavior against his or her will. Although the patient knows that this is a ridiculous idea and that he or she will not do it, he or she cannot get rid of this inner urge. For example, when standing on a bridge or riding on a train, there is an urge to jump; or there is an urge to swear or shout reactionary slogans, etc. The causes of OCD are complex and inconclusive, but it is believed that they are mainly related to psychosocial, personality, genetic and neuroendocrine factors. Therefore, for the treatment of OCD, medication is also essential, unlike other diseases, it is a long-term process, so the following principles must be followed when carrying out medication: 1. long time principle: a full dose of anti-compulsive drug therapy should be at least 3 months, some patients need a longer period of time, in order to be considered a course of treatment to end, in order to assess the efficacy, can not eat a 2-3 months to assess the efficacy. 3 months to assess the efficacy of the decision to change the drug. 2, the principle of adequate dose: anti-OCD drug therapy, the dose is generally larger, sometimes the highest dose stated in the instructions, this is because the efficacy of low dose is very bad, to apply a larger dose, of course, each patient’s situation is different, the specific dose of medication to specific analysis, but in general, anti-OCD treatment drug dose is on the large side. 3, maintenance time to be long: the largest dose of anti-OCD drugs to achieve better results, this dose is generally recommended to maintain about 6 months, and then consider reducing the dose to maintain 2-3 years. 4, with the symptoms, let nature take its course: the complete disappearance of obsessive-compulsive symptoms is more difficult, patients and family members to accept the compulsive symptoms, with the symptoms to live and learn, let nature take its course is the core of the treatment of obsessive-compulsive psychotherapy: Morita treatment, the details of which you can buy books on Morita treatment read closely and adhere to do. Before using medication, OCD patients must watch the instructions in detail and have an understanding of some of the characteristics and hazards of the medication. Psychotropic medications generally have a lot of negative effects, so it is important to follow your doctor’s instructions on how to choose and take them. Some people with OCD will repeat the check several times or even hundreds of times to make sure that the door is locked, the homework is correct, and the stove is off. Most of these compulsive actions are caused by obsessive suspicion. Compulsive actions: Compulsive actions are those in which the patient must follow a fixed set of sequences when doing a certain behavior and repeat the series of actions. If something goes wrong or is interrupted in the middle, they have to start again until they are satisfied. Recent statistics suggest that the incidence of OCD is rising, and some studies show that the lifetime prevalence of OCD in the general population is 1% to 2%, with about 2/3 of patients developing the disease before the age of 25. The World Health Organization’s Global Disease Survey found that OCD has become one of the 20 diseases that cause the greatest burden of disease among young and middle-aged people aged 15 to 44. In addition, patients often do not seek medical attention at the beginning of the disease for various reasons, and some patients who are afraid of getting dirty and repeatedly wash their hands may come to the clinic only after their symptoms are so severe that they cannot live normally, and there may be a 10-year gap between the start of the disease and the next visit, which in effect increases the difficulty of treatment.
