What are the symptoms of cerebral infarction?

Many recent data show that cerebral infarction occurs in many patients, regardless of age. We need to learn more about this disease that troubles us. Because we may not pay attention to the details in our daily lives, this disease may occur, which is a very serious situation. Especially for young people, who are under great pressure at work, if this disease occurs, it will definitely affect their life, work and study. Then you must develop good living habits. So what are the symptoms of cerebral infarction?

Cerebral embolism can occur at any age, but is more common in young and middle-aged people. It often occurs suddenly during activities, without prodromal symptoms. Focal neurological signs reach a peak within seconds to minutes, and are often manifested as complete stroke, with clear consciousness or mild confusion. Embolism of the internal carotid artery or middle cerebral artery trunk leads to large-area cerebral infarction, which may cause severe cerebral edema, increased intracranial pressure, and even brain herniation and coma, and epileptic seizures are common. Embolism of the vertebral-basilar artery system often causes coma. In some cases, focal signs are stable or improved for a period of time and then worsen, indicating recurrence of embolism or secondary bleeding.

About 4/5 of cerebral embolism occurs in the anterior circulation, especially the middle cerebral artery, with hemiplegia, hemisensory disturbance, aphasia or focal epileptic seizures. Hemiplegia is more severe in the face and upper limbs. The vertebral basilar artery system is affected in about 1/5, with symptoms such as dizziness, diplopia, crossed paralysis or quadriplegia, ataxia, coughing when drinking water, dysphagia and dysarthria. Embolism entering one or both posterior cerebral arteries causes homonymous hemianopsia or cortical blindness. Embolism of the main basilar artery causes sudden coma, quadriplegia or basilar artery tip syndrome. Most patients have rheumatic heart disease, coronary heart disease and severe arrhythmias, or embolic sources such as heart surgery, long bone fractures, and intravascular interventional treatment, as well as signs such as pulmonary embolism (shortness of breath, cyanosis, chest pain, hemoptysis and pleural friction rub, etc.), renal embolism (low back pain, hematuria, etc.), mesenteric embolism (abdominal pain, bloody stools, etc.), and skin embolism (bleeding spots or ecchymosis).

Through the above content, we understand the symptoms of cerebral infarction. The occurrence of this disease is closely related to our lives, so we should pay more attention to eating habits, not staying up late often, develop good habits of using the brain, not have too much pressure, maintain a good mood, and regularly do outdoor sports or travel, which are good for the body.
