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.

Slow electroencephalographic oscillations and behavioral measures as predictors of high executive processing in early postmenopausal females: A discriminant analysis approach.

Decline in cognitive function is frequent in early postmenopause. There are postmenopausal females who show high performance while others display low performance in executive function, modulated by the prefrontal cortex. These differences have led to confusing and inconclusive results, which have not been explained entirely by the decline in estrogens, which affect the prefrontal cortex functions.

Facial Sadness Recognition is Modulated by Estrogen Receptor Gene Polymorphisms in Healthy Females.

Polymorphisms of the estrogen receptor and genes have been linked with cognitive deficits and affective disorders. The effects of these genetic variants on emotional processing in females with low estrogen levels are not well known. The aim was to explore the impact of the and genes on the responses to the facial emotion recognition task in females.
