Brain infarction patients may aggravate their condition when they are angry. Anger tends to cause vasospasm, which can cause impaired blood supply to the brain and can cause ischemic and hypoxic changes in the brain, thus aggravating the patient’s signs and symptoms. Patients with cerebral infarction in general should try not to get angry and should keep their mood relaxed. Cerebral infarction is a common and frequent disease in neurology, with a high rate of disability and death, mostly occurring in middle-aged and elderly people, and the main causes of patients include atherosclerosis, hyperlipidemia and hyperglycemia. Cerebral infarction is a disorder of blood supply to the brain caused by various reasons, thus causing ischemic and hypoxic changes in the brain, which in turn leads to ischemic necrosis and softening of restricted brain tissue, and clinically can present with a variety of different symptoms and signs, depending mainly on the vessels involved in the lesion. In the case of infarction of the internal carotid artery system, patients generally present with hemianopia, hemiparesis, hemianesthesia, and possibly speech dysfunction. In the case of infarction of the vertebrobasilar system, the main manifestations are dizziness, nausea, vomiting, and also balance disorders and ataxia, with some patients experiencing dysphagia and choking on water, and in severe cases, impaired consciousness.
