Aims The objective of this study was to evaluate the impact of the first Italian COVID-19 lockdown on patients with chronic migraine (CM). Material and methods The study was based on an e-mail survey addressed to CM patients of our headache center. The survey evaluated demographic, life style, sleep, psychological, and migraine features during the COVID-19 lockdown period and the month before. The outcomes were migraine impact on daily life and variation in attack frequency, attack duration, migraine pain intensity, migraine symptomatic drugs use per week, and efficacy. Results Ninety-two patients completed the survey. During the lockdown period, attack frequency was stable in 40,2%, increased in 33,7%, and reduced in 26,1% of patients; attack duration was stable in 55,4%, increased in 23,9%, and reduced in 20,7%. Migraine pain was stable or reduced in 65,2% and increased in 34,8%; number of symptomatic drugs per week was stable in 50%, reduced in 29,3%, and increased in 20,7%; migraine drug efficacy was stable in 73,9%, reduced in 17,4%, and increased in 8,7%. Patients had a HIT-6 score of 64,63 ± 8,81. Significant associations were found with remote working, smoke, education, discontinuation of the therapy performed within headache center, migraine familiarity, sleep, anxiety, perceived stress, concern about future, and COVID-19. Conclusion During the lockdown, approximately half of the patients had a clinical stability, a quarter an improvement, and another quarter a worsening. We identified different migraine-influencing elements; in particular, the remote working could represent an easy way to ameliorate migraineurs’ life.

Aims The objective of the present study was to evaluate sleep features and sleep-modifying factors in patients with chronic migraine (CM) during the first Italian COVID-19 lockdown. Material and methods The study was based on an e-mail survey addressed to CM patients of our headache center. The survey investigated demographic, life-style, sleep, psychological, and migraine features during the first COVID-19 lockdown period and the month before. The outcomes were sleep quality (measured using PSQI) and variation in sleep quality, duration, and latency. Results Ninety-two patients were included. The mean PSQI was 11.96. Sleep quality was improved in 14.1%, stable in 47.8%, and worsened in 38.0%. Sleep latency was reduced in 5.4%, stable in 46.7%, and increased in 47.8%. Sleep duration was reduced in 29.3%, stable in 34.8%, and increased in 35.9%. Significant associations were found with age, work/study, remote working, job loss, meal quality change, smoking variation, COVID-19 province prevalence, home-inhabitant relationship, ratio of house size/number of people, stress, state anxiety, anxiety/depression variation, future concern variation, computer hours, internet hours, and television hours. Conclusion The study described sleep features of chronic migraineurs during COVID-19 lockdown, pinpointing the main factors involved in sleep quality and sleep changes. Our findings revealed that migraineurs’ sleep was closely linked with life-style and psychological features. Several modifiable factors came to light and they should be considered in order to develop an optimal management of CM. An appropriate and more aware treatment of sleep problems could be a way to improve migraineurs’ life.
