Cognitive, Clinical, and Biomarker Correlates of Insight in Obsessive–Compulsive Disorder: preliminary results of a cross-sectional study
… (Y-BOCS, BABS), MATRICS-defined cognitive tests, polysomnography, and serum biomarkers (BDNF, TNF-α, CRP) was analyzed in adult OCD subgroups characterized by late onset (LO) and poor insight (PI). Principal Component Analysis and supervised classification revealed two main latent dimensions—one …

Differences between Men and Women in Risk Profile of commonly used metrics in Screening for Obstructive Sleep Apnea using NHANES data.
… in symptomology. OSA is diagnosed using polysomnography which is time intensive and impracticable as a screening method. Alternate methods for screening based on symptoms exist with varying sensitivities. This study used the National Health and Nutrition Examination Survey (NHANES) based …

NREM sleep spindles and slow wave sleep in younger and elderly women: an investigation of their influence on declarative memory consolidation
… (M = 63.14±2.03 years). Participants underwent polysomnography on a baseline and experimental night and encoded a list of word-pairs of graded difficulty on the experimental night. Word-pair type included integrative, concrete and low concrete measures. Memory retention was then assessed pre- …
