Depending on the severity of the disease and the specific circumstances, stroke may present with different manifestations, such as dizziness, headache, numbness of the limbs, blurred vision, and loss of consciousness. In milder cases, dizziness and headache may be the only manifestations. If the disease worsens, there may be an increase in intracranial pressure, followed by increased headache and vomiting. When the lesion damages the basal ganglia, sudden numbness and weakness of one limb may be observed. This is accompanied by facial hemiparesis and speech disorders. Lesions in the dominant hemisphere may have speech disorders, blurred speech, and aphasia. When the lesion damages the occipital lobe, it can also damage the visual center, which can lead to blurred vision, isotropic visual field hemianopia, and in severe cases, double blackouts. When the lesion is more extensive, visual rotation, balance dysfunction, and even confusion can occur. In addition, some patients may experience seizures and urinary and fecal incontinence. Subarachnoid hemorrhage is a specific type of stroke that commonly presents with explosive headache, hemiparesis or hemianesthesia, and reemission of blood or, in severe cases, respiratory failure. When patients have similar symptoms, they should go to the hospital for brain CT and other tests as soon as possible to clarify the situation.
