In daily life, the disease of idiopathic tremor is very common. There are many patients with idiopathic tremor who suffer from the disease due to various reasons such as heartache of money, unwillingness to let their children take care of them and trouble others, so it leads to delaying the disease and putting their condition off again and again, so the golden time period for treatment is delayed. In recent years, idiopathic tremor has appeared more and more frequently in our vision, becoming the third major killer that seriously threatens the physical and mental health of middle-aged and elderly people. So what are the characteristics of idiopathic tremor? 1, the cause is unknown At present, it can only be considered that idiopathic tremor is insidious in origin, the cause and pathogenesis are extremely not completely elucidated so far, and the cause is related to genetic factors and influenced by environmental factors. In the long-term development of neurology, no clear cause has been found yet. 2. Tremor The only symptom of idiopathic tremor is tremor, with occasional reports of tone and slight gait abnormalities. Patients usually begin with the upper extremities, which are mainly affected, with a symmetrical onset in the upper extremities bilaterally or unilaterally. Once the upper extremities are affected, they often progress upward to the head, face, tongue, and jaw. The involvement of the trunk and bilateral lower extremities is rare, only in the late stage of the disease process, and the degree of lighter than the upper extremities. Family history Usually there is a family history, which means that the family members, parents, siblings may have the same performance, and it is autosomal recessive, so it is also called familial tremor. 4. Prevalent population The prevalence rate is 0.3-1.7% in the general population, increasing to 5.5% over the age of 40 and 10.2% over the age of 65. It is mostly seen in middle-aged and elderly people over 40 years old. Immediate family members (parents, siblings) who have a history of idiopathic tremor. 5, slow progression Mostly benign course, slow progression, not spontaneous remission. Usually it takes 10-20 years after the onset of the disease to become unable to work and live normally because of tremor. 6. Characteristic response to alcohol Drinking alcohol can cause a significant temporary reduction in tremor in most patients, and even small doses of ethanol can have a dramatic effect, with tremor reappearing 2-4 hours later. Early detection, diagnosis, treatment, and enhanced clinical care of idiopathic tremor are important to improve the quality of life of patients. When typical tremor symptoms appear, it is important to seek medical attention as soon as possible to determine the clinical classification of tremor. There are many diseases in which “shaking” occurs, and one of them that is very common and easily confused with Parkinson’s disease is idiopathic tremor, so it is important to understand the characteristics of idiopathic tremor and not to confuse it with other diseases.
