TL;DR: The first normative and acute total sleep deprivation data on the Cognition test battery are described as well as several efforts underway to establish the validity, sensitivity, feasibility, and acceptability of Cognition.

TL;DR: This work estimated an exploratory multilevel structural equation model (MSEM) exploring associations among environment- and individual-level variables in diverse communities and revealed that environment had the largest association with neurocognitive performance.

TL;DR: Overall results supported the interpretation of Cognition scores as measuring their intended constructs in high performing astronaut analog samples, which is an essential step toward ensuring their usefulness in long-duration space missions.

TL;DR: A novel method that combines item response theory (IRT) and computerized adaptive testing (CAT) approaches to create an abbreviated form of the computerized Penn Line Orientation Test (PLOT), which points to its feasibility for large-scale clinical and genomic studies.

TL;DR: Systemic effects of estimated glomerular filtration rate, hematocrit level, and blood pressure on CBF and alterations in regional CBF may reflect impaired brain function underlying neurocognitive symptoms in CKD.
