Idiopathic tremor, also known as familial or benign idiopathic tremor, is an autosomal dominant disorder that is the most common extrapyramidal disorder and the most common tremor disorder, with approximately 60% of patients having a family history. Idiopathic tremor is a single-symptom disorder, and postural tremor is the only clinical manifestation of the disease. Postural tremor is a tremor that is triggered when the limb is maintained in a certain position, and it disappears naturally when the limb is completely relaxed. The tremor in this disease is commonly found in the hands, followed by the head tremor, and very few patients have tremor in the lower extremities. The onset of this disease is usually in the late teens or early adulthood. The tremor of this disease is aggravated by concentration, mental stress, fatigue, and hunger, and in most cases it disappears temporarily after drinking alcohol and worsens the next day, which is also characteristic of idiopathic tremor. Examination is usually without other neurological signs. It should be treated symptomatically. Drug treatment 1, beta-blockers: 40-120mg of benzoin, divided into 2 doses, need to be taken from time to time, such as expected on specific occasions tremor is particularly severe, can be temporary oral benzoin 40-120mg; Almare better effect, less side effects, more commonly used in clinical practice, commonly used dose: 10mg twice a day, morning and afternoon; before taking the drug should be performed electrocardiogram, to exclude slow Before taking the drug, an electrocardiogram should be performed to exclude contraindications to beta-blockers such as slow rhythm and conduction block; 2, paroxetine is also effective, but patients with idiopathic tremor are often very sensitive to this drug and should not be used according to the treatment of epilepsy, and should start with a small dose of 50mg/d and increase the daily dosage by 50mg every 2 weeks until it is effective or until side effects occur; usually the effective dose is 100-150mg, 3 times/d; 3, occasional patients with alprazolam is effective. Maximum dose of 3mg/d in divided doses.
