Stroke includes cerebral infarction. Stroke is divided into ischemic stroke and hemorrhagic stroke. Therefore, ischemic stroke is cerebral infarction, and hemorrhagic stroke is cerebral hemorrhage. Thus, one cannot say it is solely a cerebral infarction; it includes cerebral infarction. If symptoms of stroke appear, such as unclear speech or limb weakness, it might be either hemorrhagic or ischemic stroke. In such cases, it is crucial to seek medical attention immediately. For hemorrhagic stroke, one should visit the neurosurgery department, and for ischemic stroke, the neurology department is appropriate. Initially, a CT scan should be performed to make a clear diagnosis.
