I'm curious if this has use as a diagnostic tool to help those who have a really hard time with executive functions but are unsure if they have ADHD.

Not likely. MRI machines cost millions of dollars and there are higher-priority diagnostic needs. The study does seem to correlate with the existing diagnostic criteria.

  I wonder what it would take for MRI machines to become commoditized? What if it were normal to have diagnostics like tumor detection at a very early stage made possible by your bed = MRI machine in disguise. Something like that would be phenomenal - daily diagnostics and now and then introspection plus treatment for things like the mentioned executive function impairment.

    Higher temperature super conductors and advances in technologies I guess. The machines are cooled with liquid helium which is expensive and requires a lot of additional tech. If you can live with a lower signal-to-noise ratio you can have lower magnetic field strength and you can maybe use liquid nitrogen. Still not stuff you want to have at home in significant amounts. Additionally you need a very homogenious magnetic field. This is accomplished by rotating the field very fast by rotating the reels (part of why the machines are so loud). If we find another way to fix this or find a way to deal with it (possibly a supercomputer with supersoftware) cost and size might go down. But this was the best solution available which indicates the size of the problem.

    MRI machines need liquid helium [1], so probably never? [1] http://en.wikipedia.org/wiki/Magnetic_resonance_imaging#How_MRI_works http://en.wikipedia.org/wiki/Magnetic_resonance_imaging#How_...

    In addition to hardware there is expensive analyais by highly trained profesionals.

  It's pretty common to do MRI-scanning when you're being diagnosed for any kind of mental disorders, just to rule out the possibility of brain damage.

    Pretty common? It's at most exceedingly rare.

      I'm sure that really depends on where in the world you live, where I live it's basically routine. I've had one for that exact reason.
