Posterior circulation ischemia may gradually recover in about 1 week, or it may take about 1~2 months, depending on the patient’s specific situation. Posterior circulation ischemia is a manifestation of insufficient blood supply to the brain, usually caused by local narrowing of cerebral blood vessels due to spasm and hardening. It is recommended to improve microcirculation by taking flunarizine and other medications under the guidance of a doctor, and the uncomfortable symptoms such as dizziness and headache will be relieved slowly. Posterior circulation ischemia may also be related to chronic diseases such as cerebral infarction, in which the recovery will be relatively slower, and the brain function will be gradually restored only after 1~2 months. Recovery from posterior circulation ischemia requires a process. In addition to proper and effective treatment as prescribed by the doctor, it is also necessary to pay attention to appropriate nutrition and adhere to regular activities and exercise in order to have a better prognosis.
