When looking at the computer for a long time, it is easy to cause the neck and shoulder muscles to contract and spasm, and prolonged neck and shoulder muscle contraction can cause insufficient blood supply to the vertebral basilar artery system. Patients mainly show signs and symptoms of cerebellar brainstem ischemia and hypoxia, and may experience dizziness, nausea, vomiting, balance disorders and ataxia, as well as nystagmus and diplopia. The contraction and spasm of neck and shoulder muscles can involve the scalp nerves and blood vessels, and the patient can also have headache, nausea, vomiting, etc. Prolonged computer viewing and eye staring at the screen may cause visual fatigue, and patients with visual fatigue can also experience dizziness. Therefore, in general, it is recommended not to look at the computer for a long time, and if you need to work on the computer, you must pay attention to rest during the process of looking at the computer. In addition, looking at the computer for a long time may cause mental tension, which may cause blood pressure to rise, and patients with elevated blood pressure can also experience dizziness. Severe hypertension may cause cerebral hemorrhage, and dizziness is the main manifestation of brainstem hemorrhage in the cerebellum. Blood pressure should be monitored promptly and cranial CT should be checked if necessary to exclude cerebrovascular disease.
