As shown on the slide, studies using prescription databases and using validated scales have shown an association between migraine and ADHD.[Arruda et al., 2020; Hansen et al., 2018; Fasmer et al., 2012] This association appears to rise throughout the third and fourth decades, and peak for people aged 50–54, which is broadly the inverse of ADHD alone, the prevalence of which peaks at age 24–26, and then declines.[Hansen et al., 2018] It could be that the comorbidity of migraine and ADHD is more common among patients later in life, or it is possible that the symptoms of migraine may be masked by ADHD symptoms in younger people.[Hansen et al., 2018]
