Zusammenfassung: | •Increasing age is associated with thinning of the cerebral cortex, with the largest effects for the occipital and temporal lobes.•Female gender and higher education are demographic variables associated with a thicker cortex.•Diabetes mellitus is a strong risk factor of a thinner cortex.
Cortical thickness is considered a potentially relevant marker for neurodegenerative diseases. However, the relationship of demographic and vascular risk factors with cortical thickness remains unclear. In a population-based sample of 1022 non-demented elderly persons (mean age 68.4±7.3 years), we examined aging effects on global and lobar cortical thickness and the relationship with demographic variables and cardiovascular risk factors. We used a validated model-based approach to calculate mean cortical thickness (μm) in brain MR-images. We found that women had a significant thicker cortex than men (p |
