Auditory Cognitive Function Assessment during Pregnancy: An Event-Related Potential and Neuropsychological Study

Objectives: We investigated the auditory cognitive and behavioral functions during 2nd 3rd trimesters of pregnancy using event-related potentials (ERPs) different neuropsychology tests, respectively.
 Methods: The ERPs were studied by a 128-sensor net, PAS/COWA, WCST, ZCT, RAVLTIM/RAVLTDR/RAVLTTS, BDI tested for assessment. Total 39 subjects recruited control group (G1, n=15, non-pregnant), trimester (G2, n=12, 13-26 weeks gestation), (G3, 26- 40 gestation). Auditory oddball paradigm was used ERP study. Subjects silently counted only target stimuli with attention ignoring standard stimuli. Value mean differences measured across groups in 10-20 electrode systems.
 Results: P50, N100, P300 components analyzed. G3 (at F7 C3) G2 T4) evoked highest significant amplitudes Cz Pz) G1 F8 N100 significantly prolonged latencies at O1 (in G1) G2). However, higher found Fz G3) FP1 (G2) (G2>G3). On other hand, tests revealed that possessed score WCST ZCT. performed poorly all tests.
 Conclusion: concluded pregnant better (attention/memory) executive function Moreover, has compared to due effect hormonal changes pregnancy, which might be positive influence period.
