Since I got unwell in Feb this year and consequently diagnosed with cfs/me around may/june. I've always been wondering if I've had the correct diagnosis. I do wonder if infact I dont have CFS, but just have a form of dysautonomia (mostly likely POTS). The reason I'm wondering is that one of the main features of ME is one of cognitive problems, and I dont seem to have this, or at least not to as great an extent as my level of physical disability would predict. In terms of my physical level, I'm fluctating around 2/3 out of 10 on the ability scale, so I have to spend a lot of time in bed or on the couch. Being up on my feet for as little as a minute is enough to make me start to feel unwell, and some rough HR measurements would indicate I have POTS, I also get pooling in my hands when I stand for long enough. Now in terms of cognitive level, my job before I got ill, and subsequently lost it last week, was as an IT programmer. So its a fairly intensive thing mentally. Even when I've been at my most ill and bedridden for up to a week, I've still been able to do this. Thou not as well, but the reduction in my ability to do it hasnt diminished by lack of mental processing, more because I dont find it easy to work while i feel so ghastly. I can also sit and read books or watch tv/films or go on the internet all day long without a problem, chatting on the phone isnt as easy thou, but I can do it. The only cognitive probs I do seem to have are a mild sound sensitivity, and continous adrenaline type feelings that arent mentally induced. So to summarise im probably operating at less than 3% of my pre-illness activity levels, and at around 90% of pre-illness mental activity. Just wondering if anyone else has profound physical disability with this, and little to no cognitive impairment, or whether I'm an anomoly and perhaps 'just' have dysautonomia?
