Introduction: Several studies have shown increased occurrence of migraine in ADHD patients. However, there is less evidence on whether migraine patients also have a higher ADHD frequency. The aim of this paper is determining whether the prevalence of ADHD symptoms or impulsivity is higher in patients with episodic migraine. Methods: An observational cohort study has been conducted. Patients with episodic migraine were included. The ADHD Rating scale, the Adult ADHD Self-Report Scale, and the scale of impulsiveness of Plutchik were used. Results: The mean value of inattention, hyperactivity and impulsivity scores on the ADHD scale was 5 ± 3.8 in cases and 2.7 ± 2.2 in controls (p < 0.00001), 4 ± 3.2 in cases and 2.5 ± 2.4 in controls (p = 0.000621) and 2 ± 1.5 in cases and 1.1 ± 1 in controls (p = 0.000407), respectively. Conclusion: Adults with migraine have a higher prevalence of ADHD symptoms. This should be considered when assessing these patients.
