Effect of lockdown during COVID-19 on migraine: A longitudinal cohort study

Background The objective of this study was to assess whether migraine-related outcomes changed during intelligent lockdown when compared with the prior period. Methods This was a cohort study evaluating the first month of intelligent lockdown in the Netherlands (12 March to 8 April 2020) compared with one baseline month (13 February to 11 March 2020). We identified 870 migraine patients treated at the Leiden Headache Center with headache e-diaries during the period of interest. Adherence to the e-diary had to be >= 80%, yielding 592 enrolled patients. Results Intelligent lockdown led to a decrease in monthly migraine days (-0.48; 95% CI: -0.78 to -0.18, p = 0.002) and acute medication days (-0.48; 95% CI: -0.76 to -0.20, p < 0.001), and an increase in general well-being (0.11; 95% CI: 0.06 to 0.17, p < 0.001). No differences in non-migrainous headache days and pain coping were observed. Consistent results were found in a subset that was followed for 4 months. Conclusions Our findings imply that intelligent lockdown measures can improve migraine disability despite of the potential negative effects of COVID-19 and lockdown. We hypothesise that this effect is a combined result of working from home, scaling down demanding social lives, and freedom to choose how to organise one's time.

Automated summary

The intelligent lockdown measures can improve migraine disability by reducing monthly migraine days and acute medication days, and increasing general well-being. Consistent results were found in a subset that was followed for 4 months.
