In the Concord Health and Aging in Men Project, 1705 community-dwelling men aged 70-97 years had detailed baseline clinical assessment of cognitive status (dementia, mild cognitive impairment [MCI] and normal cognition), as well as depression, physical activity, neuromuscular function, health status, sociodemographics, comorbidities, medication use and serum 25 hydroxyvitamin D, 1,25 dihydroxyvitamin D and parathyroid hormone levels.
<b>Results:</b> This study is the first to demonstrate that the PD-MCI-ND group presented a larger number of voxels of structural covariance in SN than the PD-MCI-D group.
During longitudinal follow-up, the mean change in neuropsychometric test scores on the Mini-Mental State Examination, the cognitive and modified Alzheimer Disease Assessment Scales (ADASs), and the Geriatric Depression Scale over time were similar in AD and MCI subjects among the 3 TSPO binding groups.
