To explore the grey matter concentration in individuals with cognitive vulnerability to depression. Methods: Thirty individuals with cognitive vulnerability to depression and thirty age- and gender-matched healthy controls were enrolled in this study, and they were subjected to magnetic resonance imaging (MRI) examination. The grey matter concentration differences were compared between the two groups by using voxel-based morphometry (VBM) following MRI. Results: Individuals with cognitive vulnerability to depression showed significantly lower grey matter density in bilateral insular, left cerebellum, right supplementary motor area, and left precentral gyrus than those in the healthy controls, while the healthy controls showed significantly lower grey density in the right inferior frontal gyrus, right middle frontal gyrus, and left cuneus than those in the individuals with cognitive vulnerability to depression. Conclusion: Structural brain abnormalities in individuals with cognitive vulnerability to depression might be the neural basis for cognitive vulnerability to depression.

Testosterone, an essential sex steroid hormone, influences brain health by impacting neurophysiology and neuropathology throughout the lifespan in both genders. However, human research in this area is limited, particularly in women. This study examines the associations between testosterone levels, gray matter volume (GMV) and cerebral blood flow (CBF) in midlife individuals at risk for Alzheimer's disease (AD), according to sex and menopausal status.

Background: Ambient air pollution, detrimental built and social environments, social isolation (SI), low socioeconomic status (SES), and rural (versus urban) residence have been associated with cognitive decline and risk of Alzheimer's disease and related dementias (ADRD). Research is needed to investigate the influence of ambient air pollution and built and social environments on SI and cognitive decline among rural, disadvantaged, ethnic minority communities. To address this gap, this cohort study will recruit an ethnoracially diverse, rural Florida sample in geographic proximity to seasonal agricultural burning.

Purpose Of Review: Using advanced bibliometric analysis, we systematically mapped the most current literature on urban air pollution and neurodevelopmental conditions to identify key patterns and associations. Here, we review the findings from the broader literature by discussing a distilled, validated subset of 44 representative studies.
Recent Findings: Literature highlights a complex relationship between environmental toxins, neurodevelopmental disorders in children, and neurobehavioral pathways involving oxidative stress, neuroinflammation, and protein aggregation.

Loneliness is one critical risk factor for cognitive health. Combining data from ongoing aging studies and the published literature, we provided the largest meta-analysis on the association between loneliness and dementia ( = 21 samples, = 608,561) and cognitive impairment ( = 16, = 103,387). Loneliness increased risk for all-cause dementia (HR = 1.

Solid organ transplant (SOT) recipients now have widespread access to telehealth, but the factors influencing their satisfaction still need to be understood. This cross-sectional study explored potential contributors to telehealth satisfaction among SOT recipients, including liver, kidney, and simultaneous liver-kidney recipients. A total of 136 adult SOT recipients completed an online survey.
