“…Chronic migraineurs were not categorized out from whole migraineurs due to small case number(4 with chronic migraine and 26 with episodic migraine). The ICHD-3β criteria for chronic migraine diagnosis required headache at least 15 days/month for least 3 months, it was restrictive to include enough chronic migraineurs compared with Expert Opinion criteria published in 2014 [52]. Fourth, the seed used in this study covered the whole RN and SN; however, the RN was subdivided into the large and small cell portions, and the SN was subdivided into the dorsal pars compacta and pars reticulata.…”

Altered functional connectivity of the red nucleus and substantia nigra in migraine without aura

Background: Functional connectivity (FC) has been used to investigate the pathophysiology of migraine. Accumulating evidence is pointing toward malfunctioning of brainstem structures, i.e., the red nucleus (RN) and substantia nigra (SN), as an important factor in migraine without aura (MwoA). We aimed to identify atypical FC between the RN and SN and other brain areas in patients with MwoA and to explore the association between RN and SN connectivity changes and performance on neuropsychological tests in these patients. Methods: Resting-state functional magnetic resonance imaging (fMRI) data were obtained from 30 patients with MwoA and 22 age-, sex-, and years of education-matched healthy controls (HC). The FC of the brainstem structures was analyzed using a standard seed-based whole-brain correlation method. The results of the brainstem structure FC were assessed for correlations with other clinical features. Results: Patients with MwoA exhibited reduced left RN-based FC with the left middle frontal gyrus, reduced right RNbased FC with the ipsilateral superior parietal lobe, and increased FC with the ipsilateral cerebellum. Additionally, patients with MwoA demonstrated significantly decreased right SN-based FC with the right postcentral gyrus, left parietal lobule, and left superior frontal gyrus. Hypo-connectivity between the right SN and right postcentral gyrus was negatively correlated with disease duration (r = − 0.506, P = 0.004). Additionally, increased connectivity of the right RN to the ipsilateral cerebellar lobes was positively correlated with the Headache Impact Test-6 scores (r = 0.437, P = 0.016). Conclusions: The present study suggested that patients with MwoA have disruption in their RN and SN resting-state networks, which are associated with specific clinical characteristics. The changes focus on the regions associated with cognitive evaluation, multisensory integration, and modulation of perception and pain, which may be associated with migraine production, feedback, and development. Taken together, these results may improve our understanding of the neuropathological mechanism of migraine.

“…Each patient completed a semistructured questionnaire under the guidance of a neurologist. The questionnaire consisted of three parts: the rst part obtained information on demographics (personal situation and family history); the second part obtained information on migraine, including the age of onset, course of migraine, triggers, duration of headache (divided into four stages: <1 hour, 1-24 hours, 24-72 hours, > 72 hours), frequency of attacks (days of attacks per month), intensity of pain on a 1-10 Visual Analog Scale (VAS), accompanying symptoms and the use of acute medication; and the third part obtained information on vestibular symptoms, including the age of onset, course, frequency of attacks, and temporal relationship with headache attacks (three answers: always, sometimes, never) (11,12). The patients were divided into three groups: the episodic migraine group (EM), chronic migraine group (CM) and tension-type headache group (TTH).…”

Objective: To evaluate the correlations between the characteristics of vestibular symptoms and migraine, and to explore the clinical value of vestibular symptoms in patients with migraine.Methods: Consecutive patients who visited the outpatient Department of Neurology and presented with a principal complaint of headache were enrolled. Patients with primary headache diagnosed according to International Classification of Headache Disorders (ICHD-3) were divided into the episodic migraine group (EM), chronic migraine group (CM) and tension-type headache group (TTH). Information on clinical symptoms was collected with a semistructured questionnaire, and the characteristics of the vestibular symptoms were recorded.Results: 451 patients were recruited, with 235 EM, 187 CM and 29 TTH. The proportion of patients with vestibular symptoms in the migraine (108/422) was higher than that in the TTH (1/29), and the frequency of vestibular symptoms in the CM was higher. 2-8 days per month was the highest in the EM (131/235), and the migraine features and accompanying symptoms were the most typical. The highest proportion of patients with separate attacks of headache and vestibular symptoms was observed in the low-frequency headache (68.8%) (p<0.05). With an increase in headache frequency, the proportion of concurrent attacks of headache and vestibular symptoms gradually increased, a headache frequency of 8 days per month was a cut-off point for migraine.Conclusion: Vestibular symptoms occur frequently in patients with CM, and the presence of concurrent attacks of vestibular symptoms and headache was significantly related to the headache frequency. A headache frequency of 8 days per month is recommended as a warning sign for CM. Patients with headaches 2-8 days per month have the most typical characteristics and should be selected for clinical trial.

“…There have been different case definitions of chronic migraine over the last couple of decades and as these defini-Schembri, et al tions have evolved, so has the epidemiology of migraine evolved. However, the diagnostic criteria for chronic migraine remain controversial [25]. The term chronic migraine is itself considered to be ambiguous, and the demarcation between the definition of chronic migraine and that of episodic migraine is deemed arbitrary.…”

“…The International Classification of Headache Disorders-2-revised allowed a higher proportion of subjects to be correctly diagnosed with medication overuse headache [ 21 ], possibly increasing its prevalence rates in epidemiological studies. However, difficulty was still found when applying the criteria in patients with medication overuse headache [ 25 ]. Many patients with more than 15 days of headache per month were likely to take analgesia for more than ten days per month, and medication overuse headache was seen as a separate diagnosis and precluded a diagnosis of chronic migraine.…”
