Head shaking is considered to be idiopathic tremor, which is a very common clinical disease, mainly manifested by positional and motor tremor of the hands or head. The tremor will be aggravated when the patient is agitated, fatigued, or nervous, and in a few cases, the symptoms can be alleviated after drinking alcohol, which is also a clinical feature of idiopathic tremor. The cause of idiopathic tremor is not very clear, about 60% of people have a family history, and the age of onset of the disease is bimodal, 20-30 years old or 50-60 years old, which are the most common ages for idiopathic tremor. The age of onset of idiopathic tremor has nothing to do with the progression of the disease, which is very slow and does not affect the patient’s daily life. The only symptom of idiopathic tremor is tremor, and very few patients experience abnormalities in tone or gait. Other diseases such as hyperthyroidism and Parkinson’s should also be excluded.
