Relationship Between Sleep Bruxism and Migraine in Children—Is It a Different History?
sleep bruxism in patients and controls showed sensibility of 100% and specificity of 88.3%. Although a few limitations of this study exist, it seems that the subjective perception of sleep bruxism was a real and important issue in this studied population of children with sporadic migraine. Further and better studies must be performed to clarify this possible relationship between sleep bruxism and migraine, especially in children.
The interesting review performed by Graziela De Luca Canto et al entitled “Association between tension-type headache and migraine with sleep bruxism: a systematic review” demonstrated a weak level of evidence to support the relationship between tensional-type headache or migraine and sleep bruxism.1 Unfortunately, little published work exists that investigates the issue. Only 2 studies of adults possessed the necessary, full criteria for inclusion in their systematic review.1 Such a situation is frustrating as the association between sleep bruxism and migraine in children has been poorly investigated. The estimated prevalence of sleep bruxism can be greater than 25% in children, and the predominance of migraine can be higher than 20% during childhood depending on the studies.2 Sleep bruxism can disrupt sleep with a consequent impairment of other chronic diseases, such as migraine.2,3 Migraine and sleep bruxism have common paroxysmal characteristics and they can share similar comorbidity and symptoms. It is possible that concomitant physiological mechanisms may overlap.4 Sleep bruxism and different kinds of headaches are related to stress, anxiety, and possible autonomic dysfunctions.5 We recently published a paper that demonstrates a higher prevalence of sleep bruxism in sporadic migraine children when compared with controls (25% vs zero).4 Interestingly, the subjective self-report used to identify
