“…The available studies suggest that this patient population might be affected by various cognitive deficits, including but not limited to poor perceptual organization, impaired visuospatial memory, slower information processing and impaired executive functions (4,5). Our own research group came to similar conclusions (6–8). Of the most recent studies, Margari and colleagues showed that both migraine and tension-type headache affect non-verbal cognitive abilities in children and adolescents (9).…”

Introduction The Rutgers Acquired Equivalence Test is a visually guided equivalence learning paradigm that involves rule acquisition and generalization. Earlier we found impaired performance in this paradigm among adult migraine patients without aura. The aim of the study was to investigate if similar impairments can be found already in the pediatric form of the disease and to compare the performance of the pediatric study population with that of an adult study population. We hypothesized that the deficits observed in adults would be observable already in the pediatric population. Methods Twenty-seven children and adolescents newly diagnosed with migraine without aura and 27 age- and sex-matched healthy controls were tested with the Rutgers Acquired Equivalence Test. Their performance data were compared to each other and those of an earlier adult study population involving 22 patients and 22 age- and sex-matched healthy controls. Four parameters characterizing performance in the two main phases of the paradigm were calculated for each of the four groups. Performance parameters were compared with Mann-Whitney U test. Results In contrast to the decreased performance of the adult patients in the Rutgers Acquired Equivalence Test, no significant difference was found between pediatric patients and controls in any phase of the paradigm. Conclusion Children living with migraine without aura do not exhibit the same cognitive deficits in the Rutgers Acquired Equivalence Test as their adult counterparts. It can be hypothesized that the deficit of equivalence learning is not an inherent feature of the migrainous cognitive profile, rather the result of the interference of the disease with normal development.

“…Other researchers also showed no group difference for foveally presented stimuli, but poorer sensitivity in migraine for peripherally presented stimuli (27). Braunitzer and colleagues (49) found reduced contrast sensitivity in children with migraine, demonstrating the possibility of the progression of the disorder. A summary of the contrast sensitivity studies is shown in Table 1.…”

BackgroundMigraine is a common neurological condition that often involves differences in visual processing. These sensory processing differences provide important information about the underlying causes of the condition, and for the development of treatments. Review of Psychophysical LiteraturePsychophysical experiments have shown consistent impairments in contrast sensitivity, orientation acuity, and the perception of global form and motion. They have also established that the addition of task-irrelevant visual noise has a greater effect, and that surround suppression, masking and adaptation are all stronger in migraine. Theoretical Signal Processing ModelWe propose utilising an established model of visual processing, based on signal processing theory, to account for the behavioural differences seen in migraine. This has the advantage of precision and clarity, and generating clear, falsifiable predictions. ConclusionIncreased effects of noise and differences in excitation and inhibition can account for the differences in migraine visual perception. Consolidating existing research and creating a unified, defined theoretical account is needed to better understand the disorder.

“…Probably the most important finding is that the marked development observed in healthy subjects between 6 and 14 years of age [27], and appearing in the controls in our own study, is not seen in migraineurs. This finding correlates well with that of our previous study [70],…”

“…Recent evidence [97] argues in favour of the latter option. The magnocellular pathway deserves special consideration, as the results of our previous study [70] on the contrast sensitivity of child migraineurs also suggested a magnocellular deficit.…”

Is the development of visual contrast sensitivity impaired in children with migraine? An exploratory study

Abstract: To our knowledge, we are the first to report on such a deficit in children, and we conclude that our findings might be interpreted as reflecting an increased vulnerability of the visual system to migraine attacks as part of the migrainous endophenotype.
