This review looked at how acupuncture affects patients with posterior circulation ischemic vertigo (PCIV). This specific type of vertigo occurs after a stroke in the back part of the brain. The review found that acupuncture, whether used alone or alongside other treatments, may increase blood flow and improve symptom scores for these patients.
However, it is important to note that the evidence for these findings is currently considered low certainty. Many of the underlying studies were small or conducted on healthy volunteers rather than people with this specific condition. Additionally, some measurements used in the research do not perfectly represent how well blood reaches the brain tissue.
Researchers are also looking into how certain biological markers and gut health might relate to these conditions. While there is an interesting link between certain factors and inflammation, these findings were mostly observed in groups without vertigo. Because this information is still early and based on a hypothesis, it is not yet a standard medical practice.
