Brain embolism is a form of cerebral infarction. The mechanism of its occurrence mainly involves abnormal objects entering the arteries, causing occlusion in the cerebral arteries and leading to brain embolism. Patients may experience paralysis, limb numbness, speech impairments, and in severe cases, even coma. The most common cause of brain embolism is due to atrial fibrillation or myocardial infarction causing mural thrombi. These dislodged thrombi travel to cerebral arteries, causing brain embolism. Generally, during the acute phase of brain embolism, bed rest is recommended along with some bedside functional exercises, such as active and passive movements of the limbs. Additionally, cardiac function must be considered since cardiac function is generally compromised in patients with brain embolism. If the treatment of brain embolism progresses well into the recovery or residual phase, and if cardiac function permits, moderate exercise such as brisk walking and slow jogging may be appropriate, but it is essential to protect the patient's cardiac function.
