Efficacy of Fish Oil Supplementation on Cognition in MCI Patients and the Influence of the APOE4 Allele

January 11, 2011 updated by: Wageningen University

Challenge Study: The Efficacy of Fish Oil Supplementation on Cognitive Performance in MCI Patients and the Influence of the APOE-epsilon4 Allele

To study the short term effects of a pharmacological dose of fish oil on cognitive performance and on cerebral blood flow. Furthermore, we want to investigate whether carriers of the APOEε4 allele respond differently to fish oil treatment compared to non-carriers.
