Cerebrovascular blockage is the medical term for cerebral infarction and cerebral thrombosis. The symptoms of cerebrovascular blockage vary depending on the location of the blockage, and the severity of the symptoms varies with the degree of cerebrovascular blockage. The clinical symptoms of cerebrovascular blockage mainly include the following categories: (1) sensory, motor and speech disorders: sensory and motor disorders are usually one limb or one side of the body, and speech disorders are mainly manifested as slurred speech, non-fluent speech or inability to understand others’ speech. (2) Dizziness: Dizziness can be a feeling of spinning, or just a feeling of dizziness, often accompanied by nausea, vomiting and other autonomic symptoms. (3) Ocular symptoms: There may be double vision, blurred vision, hemianopia, ocular motility disorders, etc. Pupil inequality often occurs in patients with increased intracranial pressure and brain herniation.
