Are the Periodic Changes of Neurophysiological Parameters During the Pain-Free Interval in Migraine Related to Abnormal Orienting Activity?

Abstract: The abnormal habituation could be explained by the periodic changes of physiological parameters during the pain-free interval. The impaired habituation of early CNV in migraine is associated with increased orienting activity seen only in the central component (AB) of OR.

“…Compared to the changes in the pupillary light reflex, the results of the cardiovascular reflex measurements favor central autonomic involvement. Previously, we discussed that the occurrence of an autonomic imbalance might provoke a migraine headache by affecting the perivascular trigeminal nerve endings [15,24,25].…”

“…None of the patients took acute medication more than two times a month. Care was taken that the time interval between the attacks and the recording be at least 5 days, as CNV amplitudes show periodic changes in the migraine interval (9)(10)(11)(12)(13)(14). At each appointment, the influence of the current state of the participants on the CNV was considered by recording the quality and duration of sleep the night before investigation, assessing mood (from 1 to 7), present medications, as well as drug, alcohol and caffeine intake on the day of recording using a standardized questionnaire.…”

“…Habituation was indicated by a negative slope, whereas loss of habituation was marked by a positive slope, as calculated by linear regression (y ¼ ax þ b, where a is the slope of habituation and b the intercept of linear regression) (33). Because only habituation of the iCNV shows relevance in the pathogenesis of migraine, only habituation of the iCNV was considered in this study (5,7,9,11,12). Three areas of interest were defined according to Gomez …”
