A Real-World Analysis of Migraine: A Cross-Sectional Study of Disease Burden and Treatment Patterns.
The purpose of this cross-sectional study was to assess the sociodemographics, disease burden, and treatment patterns of patients with episodic and chronic migraine in the United States. ⋯ This real-world analysis provides additional support for the unmet medical need for efficacious therapies that reduce migraine frequency and severity, headache-related disability, and have better tolerability for patients with migraine. In addition, further research is needed to better understand the burden of illness among patients with lower migraine frequency, and to implement treatment strategies to prevent progression of the disease.

To evaluate an e-diary developed for measuring headaches, triggers, and medication consumption, in terms of reliability and validity, and variables such as ease of use and participant compliance. ⋯ The e-diaries evaluated in this research would prove a useful tool in clinical trials of behavioral treatment for headaches.

Randomized Controlled Trial Comparative Study
Faster Improvement in Migraine Pain Intensity and Migraine-Related Disability at Early Time Points with AVP-825 (Sumatriptan Nasal Powder Delivery System) versus Oral Sumatriptan: A Comparative Randomized Clinical Trial Across Multiple Attacks from the COMPASS Study.
Fast relief of migraine pain, associated symptoms, and migraine-related disability are priorities in the acute treatment of migraine. Efforts to improve the pharmacokinetic profiles of acute migraine treatments with the aim of providing faster relief include the development of non-oral routes of administration. AVP-825 (ONZETRA® Xsail® ) is a delivery system containing 22 mg sumatriptan powder that uses a patient's own breath to deliver medication intranasally, targeting the upper posterior nasal cavity beyond the narrow nasal valve, an area lined with vascular mucosa conducive to rapid drug absorption into the systemic circulation. While most studies comparing treatments measure differences in proportions of patients achieving a dichotomous endpoint at fixed time intervals, in this study we compare trajectories of migraine pain and disability over time for AVP-825 versus 100 mg oral sumatriptan tablets. ⋯ Compared with 100 mg oral sumatriptan, treatment with AVP-825 was associated with faster reductions in migraine pain intensity and migraine-related disability starting at 10 minutes postdose and continuing through the first 30 minutes for migraine pain intensity and the first 45 minutes for migraine-related disability, resulting in lower overall pain intensity and disability that lasted through the first 2 h following treatment. Both migraine pain intensity and disability varied substantially both across subjects and within subjects across attacks.

To interrogate hippocampal morphology and structural co-variance patterns in migraine patients and to investigate whether structural co-variance patterns relate to migraine disease characteristics. ⋯ Migraineurs have less hippocampal volume and stronger hippocampal-cortico-limbic connectivity compared to healthy controls. Hippocampal volumes and measures of hippocampal volume connectivity with other cortico-limbic network regions associate with symptoms of allodynia.
