MedicalResearch.com Interview with: Jyrki Virtanen, PhD Assistant professor of nutritional epidemiology University of Eastern Finland Institute of Public Health and Clinical Nutrition Kuopio, Finland MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We have previously found in this same eastern Finnish male study population that higher egg intake was associated with lower risk of developing dementia and with better performance in tests assessing cognitive capacity. Eggs are a major source of choline, especially phosphatidylcholine, and choline (which is an essential nutrient) is necessary for the formation of acetylcholine, which is a neurotransmitter. Earlier studies have linked choline intake with better cognitive processing but there was no information whether choline intake would also be associated with lower risk of developing dementia. So the purpose of our current study was to investigate whether higher choline intake would associate with better cognitive performance and with lower risk of dementia, which would support our previous findings with egg intake. And in the current study we did find that especially higher phosphatidylcholine intake was associated with a lower risk of developing dementia and also with better performance in tests measuring memory and linguistic abilities of the men in the study.
