Hi Arno,

Yes - as part of the NYU data release there are scans from 25 adults with ADHD. If you scroll about half-way down the data page and you will find NewYork_a_ADHD.tar (n = 25 [19M/4F]; ages: 20-50; TR = 2; # slices = 39; # timepoints = 192). These data included in the publications by Castellanos et al. (2008) and Uddin et al. (2008), which I have attached here.

Best,
Clare
