At the end of World War II, a severe 5-mo famine struck the cities in the western part of The Netherlands. At its peak, the rations dropped to as low as 400 calories per day. In 1972, cognitive performance in 19-y-old male conscripts was reported not to have been affected by exposure to the famine before birth. In the present study, we show that cognitive function in later life does seem affected by prenatal undernutrition. We found that at age 56 to 59, men and women exposed to famine during the early stage of gestation performed worse on a selective …

The minimum number of trials necessary to accurately characterize the error-related negativity (ERN) and the error positivity (Pe) across the life span was investigated using samples of preadolescent children, college-age young adults, and older adults. Event-related potentials and task performance were subsequently measured during a modified flanker task. Response-locked averages were created using sequentially increasing errors of commission in blocks of two. Findings indicated that across all age cohorts ERN and Pe were not significantly different relative to the within-participants grand average after six trials. Further, results indicated that the ERN and Pe exhibited excellent internal reliability in preadolescent children …

Elevated blood levels of C-reactive protein (CRP) and homocysteine (Hcy) have received a great deal of attention as biomarkers for the development of cardiovascular disease. Their utility in predicting cognitive function has also been assessed, though the findings are equivocal. The current study examined the relationship between elevated blood levels of CRP and Hcy and their effect on cognition across several cognitive domains. As baseline blood levels of CRP and Hcy and cognition are in part regulated by genetic factors, the impact of T carrier status for variants in the CRP -286 C>T>A and the MTHFR 677C>T …
