Danish pharmaceutical company Lundbeck is presenting new real-world data from the INFUSE study at AAN 2026.

The results indicate that migraine patients report improved cognitive symptoms, such as brain fog and difficulty concentrating, following treatment with eptinezumab.

Over 50 percent reported improvement across multiple symptoms after six months, with effects observed as early as one week. The study includes patients who had previously failed to respond to other CGRP treatments.

"These real-world, patient-reported INFUSE data provide deeper insight into managing the total burden of migraine – including very common cognitive symptoms – to better support optimal treatment decisions," says Damian Fiore, Head of Medical Affairs Neurology at Lundbeck US.

"We look forward to sharing new data that can help redefine expectations for preventive migraine treatment and strengthen our commitment to raising the standard of migraine care," he continues.
