[Impact of migraine on family members: an investigation by Impact of Migraine on Partners and Adolescent Children (IMPAC)].

Using the Japanese version of the Impact of Migraine on Partners and Adolescent Children (IMPAC) and Family Question prepared based on IMPAC, we investigated the impact of migraine on family members from the perspectives of both patients and their family members. Our results showed that migraine had an impact on the family members living with the patients in Japan as well, and the perception of migraine differed partially between patients and their family members. We also found that the Japanese version of the IMPAC showed a correlation with existing instruments to evaluate impact of migraine, indicating its validity. The application of this study's findings in clinical practice could help alleviate the disease burden of migraine on patients and their family members.
