Acute migraine could be associated with neurophysiological and cognitive changes. This study evaluates the neurophysiological changes in auditory information processing in adolescents with acute migraine by means of magnetoencephalography. The multifeature sound mismatch negativity (MMN) paradigm was used to study nine adolescents with an acute migraine and nine age- and gender-matched healthy controls. Latencies and amplitudes of M100, M150, M200, and MMNm responses were evaluated. Migraine subjects had smaller M150 amplitudes than healthy subjects. The latencies of MMNm response for the frequency change were delayed in both hemispheres in migraine subjects, as compared with healthy controls. Our results indicate that the function of neural substrates, responsible for different stages of auditory information processing, is impaired during the acute migraine. The identification of underlying cortical dysfunction during an acute migraine can lead to future identification of neurophysiological biomarkers for studying acute migraine and response to treatment.

- "Several authors have shown that migraineurs, during the intercritical phase, had a lack of habituation, or even potentiation, of cortical evoked potentials during repetitive stimulation and have a strong intensity dependence of auditory evoked potentials [22-24]. One recent study evaluated the possible relationship between migraine, during attacks, and auditory processing; the authors concluded that the function of the neural substrates, responsible for auditory processing information, is impaired during the migraine attack . The aim of this study was to evaluate the correlation between auditory processing information and childhood primary headaches in the intercritical phase. "

ABSTRACT: Recently, an increasing number of articles have appeared on central auditory processing disorders, but in the literature there is only one study that evaluated the possible correlation between migraine in the critical phase and central auditory processing. The aim of our study was to assess the correlation between auditory processing information and childhood primary headaches in the intercritical phase.
This is an observational study. We enrolled 54 patients, 30 with primary headache (migraine and tension headache) and 24 normal controls, matched for sex and age. The mean age at first observation was 9 years 10 months; the duration of observational follow-up was 2 years. Both groups had normal audiological and neurological profiles, normal peripheral hearing acuity and normal cognitive and behavioral skills. We excluded patients who had undergone pharmacological prophylactic treatment for headaches in the 6 months preceding the study and subjects with a frequency of headache lower than one every two months. After enrolment, both groups were analyzed with a computerized test battery for Speech Perception Tests in silence and in noise background to assess speech perception disabilities. In addition, with a test battery of Speech Perception Tests, we compared patients with migraines and tension-type headaches. The non-parametric chi2 test, the Mann--Whitney U-test and the Wilcoxon signed ranks test were used for statistical analysis. P-values <0.05 were considered significant and STATA 10 software was used for statistical analyses.
Our results showed that patients with primary headache (migraine and tension-type headache), had a deficit of auditory processing in noisy background compared to control cases, but we found no significant differences when we compared patients with migraine and tension-type headache.
This is a work in progress and further studies are needed to assess the relationship between the impairment of auditory processing and primary headache, not only to improve the diagnostic approach to primary headache, but also to improve therapeutic intervention.

- "It has been suggested that the function of the M100 response reflects encoding of the physical features of stimuli (Naatanen and Picton, 1987). The M150 response, recorded with MEG, corresponds to the P2 response in EEG for the following reasons: (1) the dipole orientation of the magnetic M150 corresponds to the positive response in EEG; (2) M150 follows the second prominent MEG response—M100; at the same time, P2 follows the first major negative N1 response in EEG; (3) both responses occur approximately 150 ms after the stimulus onset (Chait et al., 2007a; Chait et al., 2007b; Korostenskaja et al., 2011). The M150 response is associated with the later stages of auditory information processing, such as stimulus evaluation, and corresponds to information inhibition processing (Velasco et al., 1989). "

ABSTRACT: Patients with obsessive-compulsive disorder (OCD) often report sensory intolerances which may lead to significant functional impairment. This study used auditory evoked fields (AEFs) to address the question of whether neural correlates of sensory auditory information processing differ in youth with OCD compared with healthy comparison subjects (HCS). AEFs, recorded with a whole head 275-channel magnetoencephalography system, were elicited in response to binaural auditory stimuli from 10 pediatric subjects with OCD (ages 8-13, mean 11 years, 6 males) and 10 age- and gender-matched HCS. Three major neuromagnetic responses were studied: M70 (60-80ms), M100 (90-120ms), and M150 (130-190ms). When compared with HCS, subjects with OCD demonstrated delayed latency of the M100 response. In subjects with OCD the amplitude of the M100 and M150 responses was significantly greater in the right hemisphere compared with the left hemisphere. Current results suggest that when compared with HCS, subjects with OCD have altered auditory information processing, evident from the delayed latency of the M100 response, which is thought to be associated with the encoding of physical stimulus characteristics. Interhemispheric asymmetry with increased M100 and M150 amplitudes over the right hemisphere compared with the left hemisphere was found in young OCD subjects. These results should be interpreted with caution due to the high variability rate of responses in both HCS and OCD subjects, as well as the possible effect of medication in OCD subjects.

ABSTRACT: In this article, we review clinical research using the mismatch negativity (MMN), a change-detection response of the brain elicited even in the absence of attention or behavioural task. In these studies, the MMN was usually elicited by employing occasional frequency, duration or speech-sound changes in repetitive background stimulation while the patient was reading or watching videos. It was found that in a large number of different neuropsychiatric, neurological and neurodevelopmental disorders, as well as in normal ageing, the MMN amplitude was attenuated and peak latency prolonged. Besides indexing decreased discrimination accuracy, these effects may also reflect, depending on the specific stimulus paradigm used, decreased sensory-memory duration, abnormal perception or attention control or, most importantly, cognitive decline. In fact, MMN deficiency appears to index cognitive decline irrespective of the specific symptomatologies and aetiologies of the different disorders involved.
