For those who are interested in this area, I can recommend this talk by Dr James Kustow, a London-based psychiatrist with a special interest in ADHD.
Very briefly, he suggests that there's often a link between ADHD and hypermobility/hEDS with ADHD traits being caused by a lack of blood reaching the brain as a result of chronic orthostatic hypotension.
He postulates that the efficacy of ADHD drugs is actually attributable to their side effect of increasing blood pressure.
His good news message is that simple steps such as keeping one's fluid and salt intake high and wearing compression stockings (aka travel socks) can help reduce ADHD symptoms.
