Publication Title: 
Systematic Reviews

BACKGROUND: Understanding how physical activity (PA) influences cognitive function in populations with cognitive impairments, such as dementia, is an increasingly studied topic yielding numerous published systematic reviews. In contrast, however, there appears to be less interest in examining associations between PA and cognition in cognitively healthy individuals.

Biological Psychiatry

BACKGROUND: Early life stress (ELS) experience is associated with persisting working memory (WM) deficits; changes to the corticotropin-releasing hormone (CRH) system; and structural, functional, and epigenetic changes in the hippocampus. Single nucleotide polymorphisms in the CRH receptor 1 (CRHR1) gene interact with ELS experience to predict depression as well as neuroendocrine and neuronal reactivity.

Publication Title: 
Epigenetics

Epigenetic mechanisms can mediate gene-environment interactions relevant for complex disorders. The BDNF gene is crucial for development and brain plasticity, is sensitive to environmental stressors, such as hypoxia, and harbors the functional SNP rs6265 (Val(66)Met), which creates or abolishes a CpG dinucleotide for DNA methylation.
