The development of idiopathic tremor is a relatively long process, with a long duration, a long course and a slow progression of the whole condition. There may be many patients who are not aware that they have the disease, or even come to the clinic only after being discovered by others. There is no impact on life, so it is fine to leave it untreated, and treatment is only needed at a later stage when the symptoms are more severe. There are also many patients who have tremor in their old age, when they are 70, 80 or even 90 years old, but they don’t need treatment because they can take care of themselves and it doesn’t affect their other lives. So clinically a large part of this category of patients do not need treatment, improve the mind, relaxation can be.
