Not sure how that happened, but I hit "Submit Reply" on my last post, without including the citations I had spent quite a while putting together. Something about being called to dinner. That error has now been corrected and the authorities are offered for whatever they are worth. Sorry about that.

Separately, for a nice article on neurogenic orthostatic hypertension in general, check out, “Management of neurogenic orthostatic hypotension: an update,” Low PA, Singer W, The Lancet Neurology 2008 May;7(5):451-8, NIH Author Manuscript at http://www.ncbi.nlm.nih.gov/pmc/arti...ihms-86024.pdf:

Abstract
Orthostatic hypotension (OH) is common in elderly people and in patients with disorders such as diabetes and Parkinson's disease. Grading of the severity of OH and its effect on the patient's quality of life are important. The symptoms vary with orthostatic stress, and subtle symptoms such as tiredness and cognitive impairment should be recognised. Standard drug treatment for OH is effective but worsens supine hypertension, whereas pyridostigmine can improve OH slightly but significantly without worsening of supine hypertension. Because orthostatic stress varies from moment to moment and drug treatment is suboptimal, drug treatment of OH needs to be combined with non-pharmacological approaches, such as compression of venous capacitance beds, use of physical counter-manoeuvres, and intermittent water-bolus treatment.
