Revisiting Migraine: New Criteria Unveil Hidden Intracranial Hypertension

Research Summary

A recent study published in Scientific Reports highlights the importance of revisiting diagnostic criteria for idiopathic intracranial hypertension without papilledema (IIH WOP) in chronic migraine sufferers. Researchers found that Friedman's criteria might overlook many patients, leading to missed diagnoses and ineffective treatments. By comparing Friedman's criteria with a novel approach—requiring an opening pressure (OP) above 200 mmH2O and at least two radiological signs—they identified a higher prevalence of IIH WOP at 7.8% versus 2.9%. This study emphasizes that bilateral transverse sinus stenosis (TSS) is a significant predictor of IIH WOP. Clinically, 85% of patients improved after cerebrospinal fluid withdrawal, especially those with TSS, suggesting important therapeutic implications.
