Clinical Course of Migraine during Strict Quarantine due to SARS-CoV-2: Effect of Psychiatric Comorbidities in a Clinical Cohort

Objective: During the SARS-CoV-2 pandemic, there has been a significant increase in the prevalence of anxiety and depression. This study sought to establish the probability of migraine progression by comparing data from week 0 with week 12 of quarantine. Methods: A retrospective cohort study. Three hundred ten patients were included, 238 with episodic migraine and 33 with chronic migraine; they all completed a self-administered questionnaire with demographic, clinical, and psychiatric symptom information. A multivariate statistical analysis was conducted to identify factors associated with the progression of migraine. Results: This study demonstrated a 22.5% progression probability from episodic migraine to chronic migraine with an RR 2.7 and CI (1.92-3.95, p < 0.001). The increase in depression scores (p < 0.005), anxiety (p < 0.001), and alteration in sleep quality (p < 0.003) were associated with the worsening of migraine. Conclusion: During the SARS-CoV-2 pandemic, depression, anxiety, and the deterioration of sleep quality influenced the probability of progression from episodic migraine to chronic migraine.
