I don't want to hijack this thread, so if this is an inappropriate response please let me know and I will start a new thread. I logged on today to look for information on memory and cognitive issues with POTS and possible supplements that might be helpful. We've been through the POTS ringer with my son for over a year now. He missed his entire sophomore year in high school last year. However, since April he has had some recovery. Brain fog and headaches lessened and that allowed him to complete Dr. Levine's exercise protocol, which really seems to have helped with tachycardia blood pooling and energy. He has definitely not recovered, but is SO much better than a year ago. He returned to school on Tuesday (and is unbelievably happy to be back), and we've certainly seen how much it takes out of him, but he is pushing through. We are trying to teach a 16 year old that to push through is great, but you have to know when to back off and rest as well. He said something at dinner yesterday that raised alarm bells for my wife and I. He said "My mind is like a blank slate." He can't recall information from a class, or even necessarily whether he had a given class that day, until he goes back to look at notes or his schedule. This from a former honors student. His cognition and word finding have improved since April, but I'm afraid that the effort it now takes to go through a day at school, leaves little energy for brain function. He mentioned several times during the day having to return to a classroom to retrieve a book or notebook or other item left behind. Can anyone recommend supplements? He's currently on Topomax (and I know the cog side effects - takes at night to minimize) for headaches, nystatin, florinef, VSL#3 probiotic, d-Ribose, energy revitalization system by Enzymatic Therapies, and 4g salt tabs. Sorry for the long saga. It seems that any conversation about POTS requires a lengthy dissertation! Dave
