Sleep Apnea Risk, Subjective Cognitive Decline, and Cognitive Performance: Findings from the Boston Latino Aging Study.

Introduction: Obstructive sleep apnea (OSA) is associated with subjective cognitive decline (SCD) and increased risk of cognitive decline and dementia. These relations are understudied in ethnoracially diverse groups. We examined associations among self-reported OSA risk, SCD, and cognitive performance in community-dwelling older Latinos.

Baseline neuropsychological profiles in prion disease predict survival time.

Objective: Few studies have captured the neuropsychological profile of sporadic Creutzfeldt-Jakob disease (sCJD) with neuropsychological testing, and little is known about cognitive predictors of survival. We characterized baseline neuropsychological performance in sCJD and investigated associations with survival.

Methods: sCJD participants who completed the MMSE (n = 118), 61 sCJD of whom also completed a neuropsychological battery at baseline, and 135 age-matched healthy controls, were included.
