Cerebral infarction is also often called cerebral infarction. It is caused by insufficient blood supply to the brain.

The symptoms of cerebral infarction are rapid

Cerebral embolism can occur at any age, especially in young adults. Most of them have sudden onset in the activity, without prodromal symptoms. The focal neurological signs reach the peak in a few seconds to a few minutes. Most of them show complete stroke, clear consciousness or mild confusion. The embolism of internal carotid artery or middle cerebral artery leads to massive cerebral infarction, which can lead to severe cerebral edema and increased intracranial pressure. Even cerebral hernia and coma, common seizures; Vertebrobasilar embolism often leads to coma. In some cases, the focal signs were stable or improved for a time, and then aggravated, suggesting that the embolism recurred or secondary bleeding.

About 4 / 5 of the cerebral embolism occurred in the anterior circulation, especially in the middle cerebral artery, with hemiplegia, hemiparesthesia, aphasia or focal epileptic seizures. Vertebrobasilar artery system was involved in about 1 / 5 of the patients, including vertigo, diplopia, cross paralysis or quadriplegia, ataxia, drinking cough, dysphagia and dysarthria.

Most patients are accompanied with rheumatic heart disease, coronary heart disease and severe arrhythmia, or heart surgery, long bone fracture, intravascular interventional therapy and other emboli, as well as pulmonary embolism (shortness of breath, cyanosis, chest pain, hemoptysis and pleural friction sound), renal embolism (lumbago, hematuria, etc.), mesenteric embolism (abdominal pain, hematochezia, etc.), skin embolism (bleeding point or ecchymosis) and other signs.

matters needing attention

Smoking cessation and alcohol restriction: cigarettes contain more than 3000 kinds of harmful substances. Nicotine inhaled into human body can stimulate autonomic nerve, make vasospasm, accelerate heart beat, increase blood pressure and cholesterol in blood, thus accelerating arteriosclerosis. This is the prevention of cerebral infarction should pay attention to.
