New Diagnostic Criteria for IIH in Chronic Migraine Patients

Research Summary

A recent study published in Scientific Reports explores the diagnosis of idiopathic intracranial hypertension without papilledema (IIH WOP) in chronic migraine sufferers, highlighting the limitations of Friedman's criteria. Researchers proposed new criteria, involving an opening pressure (OP) above 200 mmH2O and at least two radiological signs, which identified 7.8% of patients as having IIH WOP—more than double the rate found using Friedman's method. Importantly, 85% of these patients experienced symptom improvement following cerebrospinal fluid withdrawal, especially those with bilateral transverse sinus stenosis. This study emphasizes the need for revised diagnostic criteria to improve treatment outcomes for chronic migraine patients.
