Frequent yawning in patients with cerebral thrombosis is a manifestation of cerebral tissue ischemia and hypoxia, and it can also be used as a precursor symptom of cerebral thrombosis recurrence, so it needs to be noticed, and it is important to check yourself first, as follows: 1. Whether the various risk factors for cerebrovascular disease are well controlled; 2. Whether you insist on taking medications such as aspirin, clopidogrel, and atorvastatin calcium tablets; and 3. Whether you have a regular cerebrovascular disease reexamination. . Subsequently, we should go to the hospital for relevant examinations, including blood lipids and cerebrovascular imaging examination, the latter is the most critical, and we can choose cervical vascular ultrasound and TCD examination, or head and neck CTA examination, because patients with cerebral thrombosis often yawn, which signifies that cerebral arteries may have serious stenosis leading to insufficient cerebral blood supply, and if the delay in diagnosis and treatment may lead to recurrence of cerebral thrombosis, and in this case, we must improve the cerebral vascular Imaging examination.
