We feel that it would be very timely to present a symposium on these studies at OHBM, to give visibility to
what brain imaging is being done, and how it relates (in different ways in the different studies) to these
healthcare/epidemiology studies more broadly. We will present “early” results (including from brain imaging
of over 10,000 subjects already!), including associations between the neuroimaging data and other healthcare
and lifestyle variables. We also include a presentation covering many complex and challenging methodological
issues in such large-scale studies.
