What this trial studies

This observational study aims to explore the expression of microRNA-155 in individuals with episodic and chronic migraine. By analyzing peripheral blood mononuclear cells and monocytes, the research seeks to identify potential biomarkers that could improve diagnosis, predict treatment responses, and assess the risk of chronic migraine development. The study will involve healthy controls and patients diagnosed with episodic migraine, focusing on their miRNA profiles to better understand the neurobiological aspects of migraine. The findings could lead to advancements in migraine management and treatment strategies.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 65 with a diagnosis of episodic migraine who have maintained a headache diary for at least three months.

Not a fit: Patients with chronic migraine or other primary and secondary headache disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of reliable biomarkers for migraine, improving diagnosis and treatment options for patients.

How similar studies have performed: Other studies have shown promise in identifying miRNA signatures in migraine, but this specific focus on miR-155 is relatively novel.
