Daily associations between affect and cognitive performance in older adults with depression and cognitive impairment: a series of seven single-subject studies in the Netherlands.

Background: Comorbidity between depression and cognitive impairment is common in older adults, increases the disease burden disproportionally, and leads to diagnostic uncertainty. Insight into individual daily associations between affect and cognitive performance may help in personalizing diagnosis and treatment decisions. Our objective was to get insight into the daily associations between affect and cognitive performance within individual older adults.

Intra-Individual Variability in Cognitive Performance Can Befuddle the Study of Cognitive Impairments and Decline.

Using group-aggregated results and snapshot assessments of cognitive performance may prove problematic if the assessed construct shows substantial and rapid variation over time. To illustrate the significance of this issue, we analyzed cognitive performance data of ten older adults undergoing daily computerized cognitive assessments (CogState Brief Battery) for 36-93 days. In all cases, the day-to-day intra-individual variability was substantial when compared with group-level, between-person variability.

Associations of the Stoptober smoking cessation program with information seeking for smoking cessation: A Google trends study.

Introduction: The national smoking cessation program Stoptober was introduced in October 2012 in England and in October 2014 in the Netherlands. There is little evidence on the extent to which the Stoptober program has an impact on smoking-related outcomes at national levels. We aimed to measure the magnitude and timing of the associations of the Dutch Stoptober program with searching for smoking cessation on the internet.
