Brain embolism is a disease in the field of neurology, and one can consult a department of neurology for it. Patients with brain embolism often have a rapid onset, generally with a history of atrial fibrillation. Some thrombi attached to the heart dislodge into the cerebral arteries, causing brain embolism. Symptoms can rapidly develop, including limb paralysis and speech disorders. If the affected area in the brain is large, it may even lead to consciousness disorders and epileptic seizures. For the treatment of brain embolism, interventional thrombectomy can be performed, but there is a strict limitation on the timing window. It should be noted that patients with brain embolism have a high probability of transforming into cerebral hemorrhage, and caution must be exercised during treatment.
