Abnormal cortical activity and brainstem functioning are considered the possible etiopathogenetic factors of migraine. Monoamine oxidase A and B (MAO-A and -B) regulate the levels of monoamine neurotransmitters, so changes in their activity could participate in migraine pathogenesis. We have investigated the possible association of MAO-A and -B alleles and haplotypes with two common types of migraine, i.e. migraine without aura (MO) and migraine with aura (MA), on the sample of 110 migraineours (80 MO and 30 MA) and 150 controls. MAO-A promoter and MAO-B intron 13 polymorphisms were genotyped by the PCR-based methods. In addition, we have reevaluated the reported association between MAO-B intron 13 polymorphism and platelet MAO-B activity. The platelet MAO-B activity was determined fluorimetrically using kynuramine as a substrate. We have found a tendency toward association of the shorter variant of MAO-A gene promoter with migraine without aura in male subjects. Regarding investigated MAO-B polymorphism, no association with migraine or with platelet MAO-B activity was found. The suggestive association of the variant in MAO-A gene with migraine is considered worthy of independent replication. On the other hand, further studies on MAO-B polymorphism in migraine do not seem promising.

Spreading depolarization triggers pro- and anti-inflammatory signalling: a potential link to headache.
Brain

Institute of Neurological Sciences and Psychiatry, Hacettepe University, 06100, Ankara, Turkey.
Cortical spreading depolarization (CSD), the neurophysiological event believed to underlie aura, may trigger migraine headaches through inflammatory signaling that originates in neurons and spreads to the meninges via astrocytes. Increasing evidence from studies on rodents and migraine patients supports this hypothesis. The transition from pro-inflammatory to anti-inflammatory mechanisms is crucial for resolving inflammation.

Background: Individuals with autism spectrum disorder (ASD) experience a wide array of neurological, psychiatric and medical comorbidities, yet little attention has been given to the potential link between ASD and migraine, one of the most prevalent neurological disorders worldwide. This study aimed to investigate whether a genetic predisposition for ASD is linked to migraine and its major subtypes, with and without aura. Additionally, potential moderator and mediators of the association between ASD and migraine were explored.

Purpose: Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by recurrent episodes of fever and serositis, caused by mutations in the gene. Inflammatory pathways associated with FMF are linked to increased proinflammatory cytokines, which may be related to primary headaches, including migraine. The aim of this study was to evaluate the frequency of migraine and other primary headaches in FMF patients.

Background: This study aims to compare the posterior ocular structure parameters in children with migraine without aura (MWA), tension-type headache (TTH), and a healthy control group.
Methods: The study included 31 patients with MWA, 29 patients with TTH, and 38 healthy controls between 6 and 18 years of age. For all participants, the detailed eye examination and measurements including peripapillary retinal nerve fiber layer (pRNFL) thickness, central macular thickness (CMT), subfoveal choroidal thickness (SCT), macular vessel densities and foveal avascular zone (FAZ) parameters measured by optical coherence tomography (OCT) and OCT-angiography (OCTA), were obtained from the patient files.

Background: The term "aura" refers to a well-defined pattern of usually positive, progressive, and reversible neurological symptoms, with spreading depolarization as the underlying mechanism. While commonly associated with migraine, aura can also occur in other neurological disorders (i.e.
