Abstract Background: The demographic and clinical characteristics of vestibular migraine (VM) based on the International Classification of Headache Disorders (ICHD)-III beta are not well documented, and the underlying pathophysiology remains largely unknown. Based on evidence that central sensitization is involved in VM pathogenesis, we hypothesized that cutaneous allodynia (CA), which is a clinical manifestation of central sensitization, and interictal widespread pressure hyperalgesia (IWPH), which may be an accelerator for central sensitization, are more frequently associated with VM patients compared with non-VM patients. The aim of this study was as follows: 1) to assess differences in demographic and clinical characteristics among VM patients, patients with migraine with vestibular symptoms not meeting VM criteria (MwVS), and patients with migraine without vestibular symptoms (MwoVS); and 2) to evaluate whether VM patients were more frequently associated with CA/IWPH compared with the other two groups.Methods: This cross-sectional study enrolled consecutive migraine patients, aged 18–65. The comprehensive interview form included diagnostic questions of migraine and VM, demographic characteristics, migraine-specific variables, migraine-associated symptoms, and CA. IWPH occurrence was investigated using a manual tender point survey and clinical parameters were compared.Results: A total of 245 episodic migraineurs (mean age = 39.5 ± 11.3 years, 81.2% women) were enrolled. Based on ICHD-III beta criteria, 65 (26.5%), 74 (30.2%), and 106 (43.3%) patients were assigned to the VM group, MwVS group, or MwoVS group, respectively. Pairwise comparisons demonstrated no significant differences between the VM and MwVS groups, except for higher occurrence of headache disability in the VM group. Compared with the MwoVS group, the VM group was significantly associated with aura, severe disability, depression, tinnitus, sleep disorders, multimodal CA, and IWPH.Conclusions: There were no significant differences in clinical features between VM and MwVS groups, except for disability, which was possibly caused by criteria selection bias. VM and MwVS may be on the same disease process spectrum. Widespread multimodal CA, including clinical manifestations of thalamic sensitization, was significantly associated with VM patients compared with MwoVS patients, which indicates that thalamic sensitization may play a key role VM pathogenesis. Furthermore, IWPH may enhance susceptibility to thalamic sensitization.

Vestibular migraine (VM) is the most common cause of episodic vertigo in children. Vertigo, nausea, dizziness and unsteadiness are often complained of by children with migraine, which can precede, follow or be present simultaneously with headache. The aim of this study was to use posturography to investigate the visually evoked postural responses (VEPRs) of children with VM and compare them to data obtained from children with primary headache (M) and controls (C). Twenty children diagnosed as affected by VM, nineteen children with M without aura and twenty healthy subjects were recruited in this cross-sectional study. Posturography was performed by a standardized stabilometric force-platform (Svep-Politecnica) in the following conditions: open eyes (OE), closed eyes (CE) and during full-field horizontal optokinetic stimulation (OKN-S). Electronystagmography was performed simultaneously to analyze optokinetic reflex parameters. In the OE condition, no difference was found between groups with respect to body sway area. In contrast, this parameter increased in the two pathological groups with respect to controls in the CE condition. The optokinetic stimulations also induced a similar increase of body sway area in the M group relative to controls, but a further increase was elicited in the VM group. Electronystagmographic recording also revealed different optokinetic reflex parameters in the latter groups. This study disclosed an abnormal sensitivity of children with M and VM to full-field moving scenes and a consequent destabilization of posture, as documented by the abnormal VEPRs. Children with VM were particularly exposed to this risk. Possible clinical implications of these findings are discussed.

Abstract A study by Yaruss and Quesal (2002), based on responses from 134 of 239 ASHA accredited graduate programs, indicated that approximately 25% of graduate programs in the United States allow students to earn their degree without having coursework in fluency disorders and 66% of programs allow students to graduate without clinical experience treating people who stutter (PWS). It is not surprising that many clinicians report discomfort in treating PWS. This cross-sectional study compares differences in beliefs about the cause of stuttering between freshman undergraduate students enrolled in an introductory course in communicative disorders and graduate students enrolled and in the final weeks of a graduate course in fluency disorders.

Abstract. Conflict avoidance increases across the adult lifespan. This cross-sectional study looks at conflict avoidance as part of a mechanism to regulate belongingness needs ( Sheldon, 2011 ). We assumed that older adults perceive more threats to their belongingness when they contemplate their future, and that they preventively react with avoidance coping. We set up a model predicting conflict avoidance that included perceptions of future nonbelonging, termed anticipated loneliness, and other predictors including sociodemographics, indicators of subjective well-being and perceived social support (N = 331, aged 40–87). Anticipated loneliness predicted conflict avoidance above all other predictors and partially mediated the age-association of conflict avoidance. Results suggest that belongingness regulation accounts may deepen our understanding of conflict avoidance in the second half of life.

This investigation focuses on the question whether assessments of the development of internalizing behavior from childhood to adolescence are affected by the kind of research design (longitudinal versus cross-sectional). Two longitudinal samples of 432 second-graders and 366 fourth graders participated in a longitudinal study with subsequent measurements taken 1, 2, and 3 years later. A third sample consisting of 849 children covering the same range of grades participated in a cross-sectional study. The results show that the development of internalizing symptoms in girls – but not in boys – varies systematically with the research design. In girls, there is a decrease of internalizing symptoms (especially between the first two timepoints) in the longitudinal assessment, which may reflect, for example, the influence of strain during the first testing situation. Both longitudinal trajectories converge to a common trajectory from grade 2 to grade 7 when controlling for this “novelty-distress effect.” Moreover, when we control this effect, the slight but significant decrease characterizing the common trajectory becomes similar to the one obtained in the cross-sectional study. Therefore, trajectories based on longitudinal assessments may suggest more changes with regard to internalizing symptoms over time than actually take place, while trajectories based on cross-sectional data may be characterized by an increased level of internalizing symptoms. Theoretical and practical implications of these results are discussed.
