A multi-cohort study of longitudinal and cross-sectional Alzheimer's disease biomarkers in cognitively unimpaired older adults.

Introduction: The generalizability of neuroimaging and cognitive biomarkers in their sensitivity to detect preclinical Alzheimer's disease (AD) and power to predict progression in large, multisite cohorts remains unclear.

Method: Longitudinal demographics, T1-weighted magnetic resonance imaging (MRI), and cognitive scores of 3036 cognitively unimpaired (CU) older adults (amyloid beta [Aβ]-negative/positive [A-/A+]: 1270/1558) were included. Cross-sectional and longitudinal cognition and medial temporal lobe (MTL) structural measures were extracted.

Neural Correlates of Irritability and Potential Moderating Effects of Inhibitory Control.

Background: Irritability affects up to 20% of youth and is a primary reason for referral to pediatric mental health clinics. Irritability is thought to be associated with disruptions in processing of reward, threat, and cognitive control; however, empirical study of these associations at both the behavioral and neural level have yielded equivocal findings that may be driven by small sample sizes and differences in study design. Associations between irritability and brain connectivity between cognitive control and reward- or threat-processing circuits remain understudied.

Mpox drug wins approval in Japan-but it doesn't work.

Europe previously approved tecovirimat for mpox, based on animal data; the U.S. has stockpiled it for smallpox.

Judaism, Women's Health and COVID-19.

This issue commences with a review of the top 100 most cited papers in the Journal of Religion and Health. This is followed by Part 2 of a series examining Judaism and health related research, which is subsequently followed by an extensive collection of research specifically connected to women's health. Finally, research continues to present the unique and ongoing effects of COVID-19.
