This paper aims to evaluate changes in disease severity, disability and mood state in patients with chronic migraine associated to medication overuse (CM-MO). MIDAS was used for assessing disease activity, WHO-DAS-2 for disability, DBI-2 for mood state. ANOVA was used to test change over time; t-test to assess follow-up differences in WHO-DAS-2 and BDI-2 between patients with MIDAS <= 20 and >= 21. Change in MIDAS, WHO-DAS-2 and BDI-2 scores were computed: Pearson's index was used to assess correlation between them; linear regression to assess change in WHO-DAS-2, using MIDAS and BDI-2 change as predictors. Mean MIDAS decreased significantly (from 101.9 to 52.0). In 26.1 % of the sample, MIDAS fell below 21 at follow-up: these patients had lower WHO-DAS-2 score. WHO-DAS-2 change was little correlated to MIDAS change and strongly correlated to changes in BDI-2 scores. 57.1 % of WHO-DAS-2 change variance is explained by change in BDI-2 and MIDAS scores. There was a clear clinical improvement 14 months after detoxification, and a modest reduction in disability which is explained by reduced disease activity and improved mood state. An appropriate treatment of CM-MO, based on detoxification and prophylaxis, is likely to reduce disease burden: recognition and treatment of mood problems may be a key factor to reduce disability.
