I really wish we find out the root causes of ADHD - I believe it's a mix of genetic predisposition and upbringing to control symptoms. It looks like this research brings us a step closer.
I've heard of the kooks that put electrodes on their scalp and apply voltage to "overclock" their brains - maybe there's something to that, but with a more controlled, pharmaceutical and scientific process behind it. Provide minor stimulation to the claustrum and you end up getting more restful sleep, etc. (not to say that long-term use won't burn your brain matter out!!)
It's been such a negative thing for me, even with support systems, medication, etc.
Even if I can't be cured/helped, making sure future generations will never need to suffer as negatively as some do with the downsides of this disorder would be a great step for society.
