It is mainly based on detailed history, clinical manifestations, and appropriate examination to determine whether it is a transient ischemic attack or not.
Transient ischemic attack is a transient neurological deficit caused by local cerebral or retinal ischemia, with clinical symptoms generally lasting no more than 1 hour, and the longest lasting no more than 24 hours, with no evidence of a responsible lesion.
1. Medical history: such as hypertension, diabetes mellitus, hyperlipidemia, etc., as well as long-term smoking and drinking history.
2. Clinical manifestations: the onset of the disease is often sudden, and after a short period of time (generally not more than 24 hours), the symptoms disappear completely, often recurring; such as the internal carotid artery system transient cerebral ischemic attack, the most common symptoms are monoparesis, hemiparesis, hemiparesis, hemianopic sensory disorder, aphasia, monocular visual impairment, etc., and can also appear isotropic hemianopsia.
3. Examination: Laboratory examination mainly shows that the whole blood viscosity, plasma viscosity, hematocrit, fibrinogen and platelet aggregation rate are all increased; and imaging examination can exclude small amount of cerebral hemorrhage, cerebral infarction and other possible brain lesions.
4. Rule out other cerebrovascular diseases: for example, identify with partial epilepsy, Meniere’s disease, benign positional vertigo and other diseases.
If symptoms related to transient ischemic attack occur, one should consult a doctor in time to give targeted treatment after the cause is clarified by the doctor.
