Insomnia is a very common disorder in clinical practice, which is mainly characterized by difficulty in falling asleep, early awakening and poor sleep quality, and shallow sleep and dreams. It is not uncommon for insomnia to last for years, decades, or even decades. Patients often suffer from this and their quality of life is significantly affected. However, from my personal experience, after a more systematic and comprehensive treatment, the insomnia of patients in general will be significantly improved. Some elderly people in their 70s and 80s who have had insomnia for 30 or 40 years will also have more definite results. What is the mystery of this? Personally, I think there are three misconceptions in the treatment of insomnia: one is that insomnia is not treatable, so they give up the treatment. Such patients often have a long medical history and have been treated many times, but the effect is not significant, and finally they form a dependence on Valium-type drugs and give up further treatment. The second is to treat insomnia as a big deal and over-treat it. Patients in this category often have a relatively short medical history and feel that their symptoms are very painful, so they especially hope to improve or even cure their insomnia in a short time. If the effect is not good in a short period of time, they will be more nervous. However, this nervousness often aggravates insomnia and puts the patient in a vicious circle. Third, insomnia is treated as insomnia only, and the direction of treatment is wrong. In general, insomnia is often associated with emotional distress. And emotional distress is mostly related to two factors. These two factors, one is a long-term dissatisfaction with the real life situation or frequent encounters with irritating life events, a strong, sensitive, worrying and unwilling to let others share the personality. If the impact of the event is not eliminated, especially if the personality is not adjusted, various negative emotions will always be induced by one thing or another, which in turn affects sleep. In such a patient, insomnia will always be repeated, and sleep will be good and bad at times. Generally, if these three misconceptions are avoided and a combination of psychotherapy, medication and physical therapy is used in the treatment (some even use only one), most insomnia will still have a relatively significant effect. In clinical practice, there are many such examples.
