Migraine due to its individual and social effects is known as a major cause of disability in the world. The main complication of this disease is chronification that is known as chronic migraine (CM). It seems that several factors contribute to migraine chronification such as age, female gender, obesity and depression. Periodontitis (PD) is a common progressive inflammatory disease in the adult population that can cause destruction of surrounding connective tissue and increased loss of alveolar bones. During PD that occurs as a result of interaction between periodontal pathogen and host response, some factors such as interleukin-1 (IL-1), IL-6, C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha) which are produced locally are systemically distributed. This chronic inflammatory condition can be associated with overexpression of neurogenic biomarkers such as calcitonin gene-related peptide (CGRP), substance P (SP), neurokinin A (NKA) in CM. Hypertension, hypercholesterolemia, insulin resistance, stroke and coronary artery disease are a number of comorbidities that are associated with CM and PD. On the other hand, adipocytokines (e.g., leptin) have important role in various physiologic processes such as endothelial function, immune response and inflammation. Several studies have shown that some of them are involved in CM. High level of leptin not only contribute to pathophysiology of migraine, but also its chronicity through systemic inflammation. Chronic increasing in leptin concentration in patients with PD can worsen the inflammatory process of migraine. In conclusion, PD through increased endothelial dysfunction, systemic inflammation and trigeminovascular system activation could be involved in process of migraine chronification. Besides that, the altered concentration of adipocytokines may be a biomarker of CM which can be considered as a new therapeutic role for migraine. Although PD is mitigated as a potential factor for CM more evidence is needed to examine the effect of periodontal treatment on CM.</div> Chronic Migraine, Periodontitis, Inflammation, Adipocytokines 181 181 http://shefayekhatam.ir/browse.php?a_code=A-10-24-1191&slc_lang=en&sid=1 Marzieh Rahimi Marzieh Rahimi Rahimimr98@gmail.com 100319475328460015980 100319475328460015980 Yes Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Zeinab Sadat Hosseini Zeinab Sadat Hosseini 100319475328460015981 100319475328460015981 No Mashhad Neuroscience Research Group, Faculty of Medicine, Mashhad Branch, Islamic Azad University, Mashhad, Iran Mashhad Neuroscience Research Group, Faculty of Medicine, Mashhad Branch, Islamic Azad University, Mashhad, Iran
