Am I right in assuming MSA is multi systems atrophy?

I do know this is a late reply-- but- I think it is worth adding to the thread. Its interesting to see this in light of recent information that suggests that many ADHD symptoms are caused by orthostatic intolerance. There is also good, but incomplete SPECT evidence of diminished cerebral perfusion in ADHD- notably when upright. It may be that inattentive symptoms reflect lower cerebral perfusion, and hyperactive / impulsive symptoms reflect a sympathetic response in an attempt to preserve cerebral perfusion. It is believed, however, that stimulants such as dexamphetamine and ritalin do improve cerebral perfusion. Brain fog is common in ADHD, CFS, fibromyalgia, and dysautonomia. Having spoken to many people IMO they are similar across the board. Secondly ADHD is thought to have a neurological basis-- it is not all in our heads. ADHD symptoms are not restricted to the orthostatic ones though, there are others reflecting cerebellar and basal ganglia dysfunction. Finally because ADHD is present from childhood it is a special case- imagine growing up with orthostatic intolerance and getting in trouble at school because of the instinctive urge to fidget. We do carry some psychological baggage because of that. It's tough- it's a condition not well understood. This video, recently released by an American doctor is of great interest-- certainly to me - as I have ADHD, and now worsening dysautonomia.
