  1. Has anyone seen Dr. Sandroni at mayo Rochester? Will she prescribe treatments for pots?
  2. I don't think pots is associated with brain lesions. I had a mri done in 2005 when my pots started that had no lesions and then again in 2011 which had no lesions. There's been no mention by any research group about pots causing brain lesions.
  3. If the nerve damage was located in the hand, the neurologist probably forgot to warm the hand. POTS patients often have cold hands which can slow the conduction velocity on the oscilloscope, this can obscure the test. Also carpal tunnel syndrome could affect nerve conduction velocities in the hand. Otherwise it's always a good idea to get a second opinion. Things like diabetes could cause some peripheral neuropathy that would show up on an EMG/NCS. Also things like Guillen-Barre Syndrome or AAG could potentially cause abnormal EEG findings. Low vitamin B-12 is a possibility, but one should pro
  4. I do believe if anyone can help it will be them. But I need to see the right people while I am there.
  5. So I'm having an appointment at the Mayo Clinic In Rochester coming up. My biggest fear is going there just to have diagnostic testing done without much treatment recommendations. I've already gotten diagnosed with POTS at Baylor's autonomic center, so testing isn't going to be very helpful (they're just repeating the same tests over). Since I'm beginning medical school soon, I really need a treatment regiment to help my presyncope and there are literally no doctors where I live who're willing to treat POTS. What I'd like to do when I get to Mayo is bring out the list of medications: -Octeotri
  6. For anyone who has responded or knows someone who has responded to ivabradine, did it help the symptoms of presyncope?
  7. That's great news. Excellent work and I hope the future brings even further achievement and improvement.
  8. Your story seems similar to my own, I've had POTS now for 8 years and pretty much my remaining symptom is lightheadedness and dizziness. I would suggest getting referred to somewhere like Mayo or Vanderbilt - places that are doing research on POTS. I'm not sure about Cleveland clinic, but they're probably good too. Just don't expect your typical run of the mill doctor to know anything about POTS and/or be capable of treating it. There are a host of treatments out there, that you may want to try. Please take a look 'round these forums, you'll see a lot of good advice.
  9. I've seen publications recently about both these treatments being effective in treating POTS, but none of my doctors I believe have even heard of their use in POTS, and even if I brought them the studies I doubt they would consider it. I know a few people on this forum have tried octeotride with success, but has anyone tried EPO?
  10. That hypertension bothers me significantly, have you been tested for pheochromocytoma? What are your symptoms? Do you feel dizzy, lightheaded etc? Have your doctors suggested going to a place like vanderbilt or Mayo where they can do some vigorous testing as your case does not seem typical at all.
  11. Probably, but unfortunately the (clinical) research process is cold, rigid, and slow. I am however excited that vanderbilt is behind this study, as before there really wasn't any major academic US institution pursuing NET - it's currently mostly being done in Australia. Again, facing the options of treatment for such an autoimmune illness. It would probably be IVIG, as IVIG is the most reasonable treatment in an unreasonable environment. Ideally, we'd be able to identify the specific autoantibody or cytokine, develop a specific drug that targets such thing, and utilize that.
  12. http://dmm.biologists.org/content/early/2013/04/03/dmm.012203.abstract They found that mice deficient in NET proteins was sufficient to produce the postural tachycardia with many of the associated symptoms. In the majority of our cases, I don't think it's due to a genetic defect, but rather the epigenetic "switching off" of the expression of the gene - likely due to inflammatory factors. As found by Bayle's group.
  13. The author who suggested hypervigilance and symptom catastrophising didn't know about the paper published by the other Mayo clinic group. When I was emailing him, he told me that there was only antibodies found against nerves in some POTS patients, when I showed him the study published by Mayo about autoantibodies to the heart, he got back to me saying that wasn't around at the time of his publication and he personally just had a conversation with Dr. Low who told him the role of those autoantibodies were unclear. Anyways, this is interesting, but the only viable treatment for an ambiguous aut
  14. You can ask your doctor about going to an academic clinic like mayo, Vanderbilt, or southwestern. Preferably the former 2 as mayo and Vanderbilt have dedicated autonomic specialists. Since salt tabs help you might want to ask your doctor about florinef which helps you retain salt and water. Additionally ask your doctor about exercise as it can help a lot. Rows, jogging, stair master are all great tools that can relieve dizziness. Good luck and best,
  15. For the past 4 weeks I've been doing the stairmaster, and I've found it's been a lot more efficient at lowering my heart rate than simply jogging. Before I started this last exercise regiment I tested my HR after 5 minutes of standing (still) I was in the 112-122 range (122 max) Now I'm at 99-105 range after 5 minutes of standing, and I extended it to 6.5 minutes and it kept in that range. Symptomatically I'm about the same, but I have had an increase in partial remission moments throughout the day.
  16. Norepinephrine transporter inhibition is the only thing that consistently produces pots in healthy controls. Something to think about
  17. I do believe blood flow is being reduced, but I think for the majority of POTS patients without syncope the difference between normal and POTS is not as a large as some of the studies suggest. Stewart's paper of about a 8 or so % difference seems about right given the data I've seen. Also keep in mind Schondorf's study of a rather large group of POTS patients ~30, did not show any difference in CBF or autoregulation between POTS and controls. This can't be ignored, and in the studies demonstrating larger reductions >20% or so, one has to question if this is really outside of normal. As the
  18. Also keep in mind in these studies testing the cerebral blood flow decline they're being done on the TTT, which takes away the skeletal muscle pump. Even normal people will faint eventually without their skeletal muscle pump. In actual standing even someone with POTS will have their skeletal muscle pump greatly assisting their CBF, so you won't get the more exaggerated 40% reductions seen on the TTT. Additionally, those large of reductions are occuring with longer TTT durations, and for patients who have syncope (which would obviously drop the maximal CBFV) however, the majority of POTS patien
  19. Probably hyperventilation, you should try yoga type breathing exercises which actually train you to use less air.
  20. The abnormal oscillatory pattern of CBVF in POTS is a recurring theme that Stewart reproduced, In the first study you cited, CBF was generally maintained ~20% reduction for most of the TTT until syncope occurred. One thing that bothers me is the lack of reproducible data. Between Schondorf, Stewart, Hermosillo, and Jacob, they're all getting quite different results, except for Stewart and Jacob, who're roughly close to each other with ~20% reduction cited. I'd be interested to see the Baker Institute's results, especially if they had a larger study as I think a larger cohort is required to fl
  21. Yes, Novak might have been wrong, but the data is still there, unless he messed up collecting the data, which I doubt somewhat. Additionally, even Stewart's study didn't really demonstrate appreciable significance between controls and POTS CBF. I think controls reduced by 12% and POTS by 19% however, in astronauts before space flight they did TTT on them and found their CBF decreased by 28%. These are astronauts before space flight without POTS. http://jp.physoc.org/content/579/3/799.full.pdf So that 19% or so reduction found by Stewart's group doesn't really concern me. Now, the POTS patient
  22. Interesting case study in that it documents a substantial decrease in cerebral perfusion with POTS, yet had an increase in blood pressure. I don't know why the mayo clinic is maintaining the view that cerebral perfusion is not compromised in POTS patients with studies like these. Vagal palsy seems like a much more severe form of autonomic disturbance than what most POTS patients present. (The dysphagia + slurred speech for example) so maybe that's representing the extreme of parasympathetic withdrawal. But then also there have been vagal palsy patients without POTS, so the conundrum still exis
