The so-called cerebral embolism primarily refers to the presence of abnormal substances in the arteries, which block the smaller arteries leading to arterial occlusion, causing severe cerebral ischemia and hypoxia, and resulting in the necrosis of brain tissue. It generally occurs in patients with atrial fibrillation, where atrial fibrillation can form larger emboli that detach from the heart and can easily cause cerebral embolism. The symptoms of the onset are very sudden and rapidly reach their peak. Patients may experience coma and consciousness disorders, fixed staring of the eyes, paralysis of limbs, numbness of limbs, and an inability to sense pain and temperature in the limbs. Additionally, some may experience epileptic seizures and urinary and fecal incontinence. Cerebral embolism is a very dangerous disease, and once these symptoms appear, it is crucial to seek hospital treatment as soon as possible.
