Background And Objectives: Menopause and menopausal hormone therapy (MHT) affect cognition, although existing studies are inconclusive. Age-related declines in executive functions, episodic memory, and prospective memory may be differentially sensitive to menopause age and MHT, due to variations in which brain regions are involved and their estrogen receptor density. Few studies have explored how menopause age and estradiol (E2)-based MHT by administration route affect these domains, a gap that this study addresses.

Thyroid hormones have been suggested to influence cognitive function in various psychiatric disorders, but their role in schizophrenia remains unclear. This study aimed to explore the relationship between thyroid hormone levels and cognitive performance in patients with chronic schizophrenia.

Patients often express complaints of neuropsychological symptoms and cognitive impairments including lack of attention.

Introduction: Early life bilateral salpingo-oophorectomy (BSO) leads to immediate estradiol loss and increased risk of late-life Alzheimer's disease (AD). We investigated risk and resilience (RandR) on the average of 5 years post BSO and their possible impact on subjective cognitive decline (SCD), and brain structure.
Methods: A cohort in Canada (n = 333) included women with and without BSO of whom some reported SCD.

The use of combined oral contraceptives (COCs) is associated with subtle differences in brain activity and in certain cognitive, perceptual, or affective processes among current COC users compared with non-users. Whether any differences persist after the COCs are discontinued is essentially unknown. In a retrospective analysis of a cognitive dataset from healthy adults (N = 221, M = 23.
