University College London MedicalResearch.com: What is the background for this study? Response: Prior research indicates that napping can enhance performance on specific cognitive tasks. However, some authors argue that the advantages derived from napping may vary between individuals who frequently have a nap and those who never naps. Furthermore, it remains to be seen whether habitual daytime napping has a positive or negative impact on cognition and the association between napping and brain volume is not well characterized. Therefore, our study aimed to examine whether the association between genetic liability to daytime napping, cognitive function, and brain volumes might be causal using a technic called Mendelian randomization and the UK Biobank.
