There are many reasons for hand tremors in cerebral infarction, which can be seen in the localized ischemia, hypoxia, and necrosis of brain tissue caused by cerebral infarction, which in turn can affect brain-related functions and lead to hand tremors in patients. In addition, it can also be seen in other related diseases, such as endocrine diseases like hyperthyroidism and motor neuron disease, which can lead to hand tremors. If we want to clarify the specific cause of the patient, we should combine clinical examination, relevant blood and imaging tests to further clarify. At the same time, for the cause of hand tremors in patients with cerebral infarction, secondary prevention measures for cerebrovascular diseases should be actively taken in the treatment, such as giving low salt, low fat and other related dietary structure adjustment. At the same time, anti-platelet and lipid-lowering drugs such as aspirin and simvastatin should be taken to further control the related high-risk factors of patients.
