|Whitehall II (MRI Substudy)
|Whitehall II MRI
|The Whitehall II (MRI Substudy) randomly recruited 800 participants from wave 11 of the Whitehall II study to come to Oxford for detailed neuropsychologcal, psychiatric and MRI investigations between 2012 and 2016. Data on T1-weighted structural MRI, FLAIR, T2*-weighted, DTI and resting state fMRI are available for most participants. Just like the Whitehall II study, the MRI substudy aims to understand the causes of age-related heterogeneity in brain and mental structure and function. By combining over 30 years of data on social inequalities, lifestyle and chronic disease with new clinical measures of cognitive function, mental disorders and physical functioning, insights into individual and social differences and brain mechanisms in the development of frailty, disability, dependence, depression and dementia can be gained.
