Is transient cerebral ischemia severe?

Transient cerebral ischemia is cerebral ischemia caused by microembolism. The scope is very small. The scope and severity of general neurological deficit are relatively limited. Transient cerebral ischemia occurs suddenly. Local cerebral or retinal dysfunction lasts for a short time. The attack lasts for several minutes. Normally, it completely recovers within 30 minutes. The longest period does not exceed 24 hours. It is worth noting that transient cerebral ischemia may lead to cerebral infarction if it is not taken seriously.
