Idiopathic tremor, also known as familial or benign idiopathic tremor, has a family history of about 60%, and postural or motor tremor is the only symptom, which can progress slowly or not for a long time. Severe physical tremor also affects patients’ lives equally, leading to a reduced quality of life, and because people know less about idiopathic tremor, they do not pay attention to it and do not take measures, leading to the progression of some patients to aggravate it. 1, the only symptom of idiopathic tremor is tremor, occasionally reported with intonation and slight gait abnormalities. Patients usually start with the upper extremities, mainly affecting the upper extremities, with a symmetrical onset in the upper extremities bilaterally, or unilaterally. The disease progresses upward to the head, face, tongue, and jaw. The tremor can spread to the whole body. 2. The tremor of idiopathic tremor is mostly postural tremor and may contain motor, intentional or resting tremor components at the same time. The tremor may be aggravated by movement directed to the purpose. The frequency of tremor is 4~8Hz. The frequency is 8~12Hz at the onset of the disease, and gradually decreases and increases in amplitude with the duration and age of the disease. 3. Patients with idiopathic tremor have rhythmic abduction of the hands, with inward and flexion-extension-like tremor, and spin-forward and spin-backward-like tremor (similar to Parkinson’s disease) is very rare. Writing may be distorted, but does not manifest as under-writing. Another commonly affected area is the craniocervical muscle groups. The head, tongue, or vocal muscles can be involved, and head tremors are manifested as vertical “head nodding” or horizontal “head shaking” movements. Tremor of the soft palate and tongue can lead to vocal difficulties. 4. Idiopathic tremor can be found in children, adolescents, middle-aged and elderly people. There are two views on the peak age of onset. One believes that the distribution of the age of onset is bimodal, i.e., in the age groups of 20-30 years and 50-60 years; the other believes that idiopathic tremor rarely develops in adolescents, and the number of onset increases with age, with an average age of 37-47 years. 5, idiopathic tremor is aggravated by concentration, nervousness, fatigue, hunger, and in most cases, it disappears temporarily after drinking alcohol and worsens the next day. The above is the characteristic manifestation of idiopathic tremor, and I hope it can help you understand idiopathic tremor more comprehensively and treat it in time, whether it is medication or surgery, which can effectively control the tremor, improve the quality of life and delay the The progression of the disease.
