The potential link between chiropractic neck manipulation and the risk of stroke, particularly vertebrobasilar artery (VBA) stroke, has been a topic of considerable debate. This synthesis aims to present the key findings from multiple research studies to address whether chiropractic care can cause strokes.
Association in Younger Patients (<45 years):
No Significant Association in Older Patients (≥45 years):
Comparison with Primary Care Physician (PCP) Visits:
Low Incidence of Stroke:
Potential Bias and Confounding Factors:
Case Reports and Alternative Explanations:
The research indicates a potential association between chiropractic neck manipulation and an increased risk of VBA stroke in younger patients (<45 years). However, this association is not observed in older patients (≥45 years). The increased risk seen in both chiropractic and PCP visits is likely due to patients seeking care for early symptoms of arterial dissection. Overall, the incidence of VBA strokes is very low, and the evidence does not conclusively establish chiropractic care as a direct cause of stroke. Further high-quality research is needed to clarify these findings.
