jangle Posted February 22, 2012 Report Share Posted February 22, 2012 The thing is I don't think its an arteriosclerotic issue with pots. They tend to have white matter hyperintensities on brain mri as well as microalbuminuria (protein in urine since the kidneys and brain are very similar vascularly) neither of which are commonly associated with pots. Though I do believe we have an incorrect hormonal or baroreceptive response to orthostatic stress. Quote Link to comment Share on other sites More sharing options...
kluesyk Posted February 22, 2012 Report Share Posted February 22, 2012 I do have white matter hypersensitivites that I never had prior to POTS so maybe is related. Quote Link to comment Share on other sites More sharing options...
jangle Posted February 22, 2012 Report Share Posted February 22, 2012 POTS can give you risk factors such as high blood pressure and sleep apnea which definitely need to be controlled. Quote Link to comment Share on other sites More sharing options...
ramakentesh Posted February 22, 2012 Report Share Posted February 22, 2012 Yeah its all about postural changes with normal blood vessels in pots. the body does interesting things to brain blood flow when there is parasympathetic withdrawal as a result of reduced stroke volume.
