[Freesurfer] Desikan-Killiany atlas - ideal for all age ranges?

Dear FreeSurfer experts

I have one question regarding the labeling of cortical structures using the Desikan-Killiany atlas and couldn't find any information in the archives. As far as I read, this atlas has been composed by including 40 subjects of broad age ranges (19-86 years of age), with 10 of them suffering from Alzheimer's disease. Since I am mainly working with data sets of much younger non-demented subjects (early twenties), I was wondering if it was more accurate to make use of a young subset of the Desikan-Killiany atlas to optimize the labeling of cortical parcellations and if that was possible at all?

Thank you very much for your help!

All best wishes Martina
