Percentage of patients who reported experiencing brain fog (A) and improvement after eptinezumab treatment (B)

Percentages may not add up to 100% due to rounding. Patients were asked: “Have you experienced ‘brain fog’ (feeling confused, have difficulty learning or remembering, or have trouble speaking or reading)? If yes, please rate to what extent your symptoms have improved since starting eptinezumab.” Choices included: completely, very much, moderately, slightly, or not at all.
