The present invention relates to the field of detecting/preventing migraine attacks. In particular, a system and method for detecting and preventing a migraine episode in a user are provided. The system comprises a brain activity sensor for detecting a brain activity signal a migraine trigger detection unit for detecting potential migraine triggers, said potential migraine triggers being circumstances that may potentially cause a migraine attack in the user. A processing unit is configured to: process the brain activity signal to identify one or more signal characteristics in the brain activity signal that are indicative of an upcoming migraine attack in the user identify one or more correlations between the one or more identified signal characteristics in the brain activity signal and the detected potential migraine triggers determine, based on the identified one or more correlations, one or more personal migraine triggers that are likely to cause a migraine attack in the user an output unit for providing the user with a personalized feedback which informs the user about the determined one or more personal migraine triggers and/or how the user may prevent the determined one or more personal migraine triggers.
