摘要

本研究旨在比较绝经后早期与绝经前对静息态脑电频谱功率的影响,并分析脑电频谱功率值与内源性卵巢激素水平之间的相关性。这项研究涉及 13 名绝经后早期妇女和 10 名绝经前妇女,她们分别处于卵泡早期、排卵期和黄体早期,并接受了闭眼静息态定量脑电频谱功率和内源性卵巢激素测量。比较了绝经后早期组和绝经前组的δ、θ、α1、α2、β1 和β2 绝对功率。分析了绝经后早期妇女脑电图频谱功率值与 17β 雌二醇、孕酮、卵泡刺激素(FSH)和黄体生成素水平之间的相关性。与绝经前组相比,绝经后早期组的额叶区静息θ功率、额叶区和中央区的α1和α2功率、额叶区、中央区、顶叶区和枕叶区的β1功率以及顶叶中央区的β2功率均明显较高。β2功率值与前列腺素水平呈正相关。目前的研究结果表明,绝经后早期妇女的静息态α和β功率更大,这表明大脑皮层的快速频带兴奋性与警觉状态、注意力集中、认知和情绪有关。此外,我们还强调了 FSH 水平对绝经后早期妇女大脑皮层快速激活的影响。

Effect of early postmenopause and premenopause on resting-state electroencephalographic and their correlation with ovarian hormone levels.

This study aimed to compare the effect of the early postmenopausal period on resting-state electroencephalographic spectral power with that of the premenopausal period and to analyze the correlation between electroencephalographic spectral power values and endogenous ovarian hormone levels. This study involved 13 early postmenopausal women and 10 premenopausal women in the early follicular, 10 in the ovulatory phase, and 10 in the early luteal phase who underwent resting-state quantitative electroencephalographic spectral power with eyes closed and endogenous ovarian hormone measurements. The delta, theta, alpha1, alpha2, beta1, and beta2 absolute power were compared between the early postmenopausal and premenopausal groups. Correlations between electroencephalographic spectral power values and 17β estradiol, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone levels were analyzed in early postmenopausal women. Compared with the premenopausal group, the early postmenopausal group showed significantly higher resting-state theta power in the frontal region, alpha1 and alpha2 power in the frontal and central regions, beta1 power in the frontal, central, parietal, and occipital regions, and beta2 power in the centroparietal region. Beta2 power values were positively correlated with FSH levels. The current findings highlight that early postmenopausal women show greater resting-state alpha and beta power, which suggests cortical excitability of fast frequency bands involved in states of alertness, focus of attention, cognition, and emotion. Additionally, we emphasized the effect of FSH levels on fast cortical activation in early postmenopausal women.

期刊介绍: NeuroReport is a channel for rapid communication of new findings in neuroscience. It is a forum for the publication of short but complete reports of important studies that require very fast publication. Papers are accepted on the basis of the novelty of their finding, on their significance for neuroscience and on a clear need for rapid publication. Preliminary communications are not suitable for the Journal. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool. The core interest of the Journal is on studies that cast light on how the brain (and the whole of the nervous system) works. We aim to give authors a decision on their submission within 2-5 weeks, and all accepted articles appear in the next issue to press.
