Contingent negative variation for the periodicity of migraine attacks without aura.

Contingent negative variation for the periodicity of migraine attacks without aura. J Integr Neurosci. 2019 Sep 30;18(3):269-276 Authors: Tian Q, Xu S, Guo Y, Li J, Han M, Ma Y, Hou X, Chen J, Luo D, Hong Y, Nie S, Liu X Abstract Migraine is a primary neuropsychological disorder, although its etiology and pathogenesis are unknown. It has been reported that using contingent negative variation, the periodicity of migraine attacks is three days in adults. However, there is still a lack of relevant reports about the periodicity of migraine without aura in adults. Therefore, we investigated the changes of contingent negative variation in adults with migraine without aura from three to seven days after migraine attacks in order to provide the basis for exploring the circulation periodicity of migraine without aura. This prospective, observational study involved a group of 34 individuals with migraine without aura, who were screened during the three to seven days after a migraine attack without aura. A healthy group (31 individuals) was used as controls to assess the amplitudes of contingent negative variation and habituation of early contingent negative variation. Indices of the amplitudes included overall contingent negative variation, initial contingent negative variation, terminal contingent negative variation, and postoperative negative contingent variation. Differences between these indicators were analyzed. No significant difference ...
