Transient ischemic attack occurs before cerebral thrombosis, and patients may experience numbness in the face, weakness in the upper and lower extremities, headache, and unsteadiness in walking. Transient ischemic attack, abbreviated as TIA, is mainly characterized by transient hemiparesis, such as limb dysfunction, slanting of the mouth and eyes, slurred speech, or change of vision, blurred consciousness, dizziness, and other symptoms. After the symptoms of cerebral ischemia appear, it is necessary to conduct timely examination and intervention when necessary, because if the precursors of cerebral thrombosis do not intervene in time, it is likely to develop into a more serious large area of cerebral infarction, and the patient’s hemiplegia, aphasia and impaired consciousness will occur, and further development may lead to brain tissue swelling and brain herniation. Therefore, if the precursor of cerebral thrombosis appears, the patient should go to the neurology department of the hospital for examination and relevant treatment in a timely manner. Especially, it is necessary to pay attention to the intervention of patients’ underlying diseases, such as diabetes, hyperlipidemia, hypertension, etc. Patients should control blood sugar, blood lipid and blood pressure in time, and they should have a low-sugar, low-salt and low-fat diet, stabilize their emotions and ensure their sleep quality.
