Interferon beta (IFN-β) therapy is one of the most commonly prescribed immunomodulatory therapies in relapsing-remitting multiple sclerosis (RRMS). A reversible cerebral vasoconstriction syndrome (RCVS), associated with IFN-β use, has been recently described. For this reason, we tested the effect of once a week intramuscular administration of IFN-β-1A on the function of cerebral vessels in a cohort of RRMS patients. Using transcranial Doppler (TCD) ultrasound, we measured the mean blood flow velocity (MFV) in intracranial vessels 10 h after IFN-β administration. Measurements showed a significant increase in MFV compared to the baseline values in some vessels.
