The symptoms of unconscious slight head shaking in patients around 50 years old may be due to the patient’s high work pressure and long-term mental tension in recent times. It is recommended that patients should keep a relaxed mood, reduce the pressure in life and work, do not stay up late, ensure sufficient sleep, and participate in aerobic outdoor exercises to improve the symptoms of slight head shaking. In addition, this condition may be related to idiopathic tremor, Parkinson’s disease, cerebellar lesions and other diseases, in medical terms, called “tremor”. 1, idiopathic tremor: is a common movement disorder with tremor as the only manifestation, with a certain genetic tendency. Idiopathic tremor is a lifelong disease that cannot be cured, but it does not affect the life expectancy of patients. The disease is most often seen in middle-aged and elderly people and causes patients to have hand tremors and head tremors. Patients with mild symptoms that do not affect their daily life do not need to be treated; patients with more severe symptoms need to be medicated under the guidance of a doctor, while surgical treatment can be chosen from deep thalamic electrical stimulation, thalamic disruption and other methods of treatment; 2. Parkinson’s: is a common neurodegenerative disease in middle-aged and elderly people, increasing with age, slightly more men than women. The main symptoms are resting tremor, delayed and reduced movements, increased muscle tone, and postural instability. This group of patients is recommended to adopt a comprehensive treatment approach, including drugs, physical therapy, hydrotherapy, medical sports and daily life adjustment and surgery, etc., of which clinical drugs mainly include anticholinergic drugs, antihistamines, etc.; 3. Cerebellar lesions: including cerebellar infarction, cerebellar hemorrhage, cerebellar tumor, cerebellar inflammation and cerebellar atrophy, etc. Patients mainly manifest dizziness, nausea, vomiting, balance disorders and Ataxia, intentional tremor can also occur, i.e., the closer the movement is to the target, the more obvious the tremor performance. The cause of the disease is different, and the treatment method is different and needs to be tailored to the specific lesion.
