Migraine pathophysiology is complex and probably involves cortical and subcortical alterations. Structural and functional brain imaging studies indicate alterations in the higher order visual cortex in patients with migraine. Arterial spin labeling magnetic resonance imaging (ASL-MRI) is a non-invasive imaging method for assessing changes in cerebral blood flow (CBF) in vivo. ⋯ Our results suggest that extrastriate brain regions probably involved in cortical spreading depression are associated with CBF changes in the interictal state. We conclude that ASL-MRI is a sensitive method to identify local neuro-functional abnormalities in CBF in patients with EM in the interictal state.

Randomized Controlled Trial
Onset of Efficacy Following Oral Treatment With Lasmiditan for the Acute Treatment of Migraine: Integrated Results From 2 Randomized Double-Blind Placebo-Controlled Phase 3 Clinical Studies.
To expand on available information on the efficacy of oral lasmiditan for the acute treatment of migraine with particular focus on the timing of the effect and on its impact on migraine-associated symptoms. ⋯ Patients treated with lasmiditan for a migraine attack reported an earlier onset of efficacy compared with those treated with placebo. Some of the efficacy measures such as pain relief demonstrated improvement as early as the first assessment at 30 minutes after 100- or 200-mg lasmiditan treatment.

This analysis assessed migraine-related burden and treatment decisions in Chronic Migraine Epidemiology and Outcomes (CaMEO) Study survey respondents who stopped taking acute prescription medications for migraine. ⋯ People with migraine who discontinue acute prescription medication have a high level of unmet treatment need. The majority cannot work or function normally with headaches, with 646/1719 (37.6%) of discontinued users reporting 5 or more headache days per month.

Randomized Controlled Trial
A Randomized Phase 2 Study of Erenumab for the Prevention of Episodic Migraine in Japanese Adults.
A phase 2, double-blind, placebo-controlled study to evaluate the efficacy and safety of erenumab for the prevention of episodic migraine in Japanese patients was conducted. ⋯ Monthly subcutaneous injections of erenumab 70 mg demonstrated statistically significant and numerically maximal efficacy with a favorable safety profile, suggesting that erenumab is a potential new therapy for migraine prevention in Japan.

Randomized Controlled Trial
Early Onset of Efficacy With Fremanezumab for the Preventive Treatment of Chronic Migraine.
To assess the onset of efficacy for fremanezumab in chronic migraine by evaluating pain-related clinical measures at different time points. ⋯ The early onset of efficacy of fremanezumab may have the potential to improve patient compliance and clinical outcomes.
