Cerebral infarction refers to an acute cerebrovascular disease caused by insufficient blood supply to the brain due to vascular blockage. If left untreated, it may lead to serious consequences such as aphasia, paralysis, and even death. Therefore, understanding the symptoms and diagnostic methods of cerebral infarction is very important.
1、 Symptoms of cerebral infarction
1. Limb weakness or numbness
Patients with cerebral infarction often experience symptoms of limb weakness or numbness, usually manifested as abnormal sensations in the arms or legs, or muscle weakness that is difficult to control. This situation usually only occurs on one side of the body, which means that if the left brain is affected, symptoms will appear on the right body, and vice versa.
2. Aphasia or unclear speech
Aphasia or unclear speech may also be a problem that stroke patients may face. This is due to damage to the language center in the brain. Patients may find themselves unable to express themselves correctly with vocabulary, or have unclear pronunciation when speaking, or even completely unable to speak.
3. Vision problems
Patients with cerebral infarction may also encounter vision problems, such as blurred vision, double vision, or blindness when seeing things. This kind of problem usually only occurs on one side of the eye.
4. Headache
Headache is one of the common symptoms in patients with cerebral infarction, usually occurring around the damaged brain area. This type of headache is usually severe and lasts for a long time.
5. Consciousness disorders
In some extreme cases, patients with cerebral infarction may experience consciousness disorders, such as coma or confusion. This situation is usually caused by severe damage to the brain.
Cerebral infarction is a serious cerebrovascular disease, and if the above symptoms occur, immediate medical attention should be sought. If diagnosed and treated early, it can minimize brain damage and improve the success rate of treatment to the greatest extent possible.
2、 Diagnostic methods for cerebral infarction
1. Medical history inquiry and physical examination
Doctors need to inquire about the patient's symptoms, disease history, medication use history, and family disease history to understand the patient's basic situation. During the physical examination, indicators of the nervous system, heart and lungs can be examined, including the patient's eyes, limb sensation, muscle strength, reaction speed, language function, posture balance, and other aspects.
2. Brain imaging examination
Brain imaging examination is an important medical method, which includes various techniques such as CT (computed tomography) and MRI (magnetic resonance imaging). These tests can help doctors determine whether there are vascular blockages, ischemic areas, and other disease conditions in the brain, thereby providing more accurate diagnosis and treatment plans for patients. Specifically, CT scans can quickly determine whether there are bleeding or ischemic areas in the brain, while MRI scans can observe the brain's condition in more detail, providing doctors with more comprehensive information.
3. Blood examination
Blood examination can check various indicators in the blood, such as hematocrit, platelet count, prothrombin time, etc., in order to determine whether there is thrombosis. If the platelet count is too high or the prothrombin time is too long, it may indicate a risk of thrombosis.
4. Electrocardiogram examination
Electrocardiogram can check the functional status of the heart in order to assess the presence of heart disease and whether there is cardiogenic cerebral infarction. If the patient has heart disease or abnormal electrocardiogram, it may increase the risk of cerebral infarction.
5. Cerebral angiography
Cerebral angiography is a highly precise examination technique that observes the state of cerebral blood vessels by injecting contrast agents, in order to accurately diagnose conditions such as vascular stenosis and occlusion. Due to its complexity, this examination needs to be conducted within the hospital.
In short, understanding the symptoms and diagnostic methods of cerebral infarction is crucial. Only early detection and treatment can minimize brain damage and improve the success rate of treatment. In addition, preventing cerebral infarction is also very important, such as maintaining a healthy lifestyle and controlling chronic diseases. Therefore, we should jointly pay attention to cerebral infarction and protect our brain health.
