QuoteSumatriptan is structurally similar to serotonin (5HT), and is a 5-HT (types 5-HT1D and 5-HT1B) agonist. The specific receptor subtypes it activates are present on the cranial arteries and veins. Acting as an agonist at these receptors, Sumatriptan reduces the vascular inflammation associated with migraine.Is inflammation causing a run out of serotonin and then tryptophan and then vitamin B3 ?

"The Science of Orgasm" author responded to my inquiry about their recently published Rutgers University (NJ) study of fMRI's of female orgasm.Dear Demografx,Thank you for your interest in our research. I have attached a copy of the poster that we presented. The ipad on the poster contained the video of the fMRI animation of brain activity related to orgasm. It can be viewed on You Tube.Please let me know if you have questions or comments about our poster.Barry R Komisaruk, Ph.D.If anyone wishes to see the attached poster he presented, PM me your regular (@) email address. Demo.
I'm looking forward to seeing the people at Hopkins and I will most definitely provide updates. I wasn't too keen on cognitive behavioral therapy either, however, the neurologists tell me that the results actually alter the brain. And that this is supported by functional MRI's. Quite honestly, given that the Imitrex they have prescribed has provided much needed and unexpected relief, I am more than willing to follow their recommendations.
So....I was in a busy cafe with my laptop today and thought I could get away with checking poiscenter.com, expecting the usual innocuous homepage with poiscenter.com in tiny letters to appear. But no.....Post Orgasmic Illness Syndrome (P.O.I.S.)!!!!!!Nice work on the new homepage Daveman thanks! ( no seriously, its coming together well)I did my best to look like a doctor who studies such things!

And could well be like Victor says, if you have the pre-cursor and can't use it, the solution is one, but if you are low in production of the pre-cursor the solution is the other.Diabetes is that way. There are two types of insulin, one in which the body lacks insulin, and another where the body has enough but doesn't know how to use it. Two completely different solutions, same final result.So in POIS, I think that's what we are looking at.It's incredible what we can do as lay-people, isn't it!!??
What they think happens in a migraine is that the vessels at the base of the head constrict, this causes the vessels higher up in the head to dilate as a compensatory mechanism to counteract for the decrease blood flow, this dilation causes the headache. The triptians selectively bind to 5ht receptors and cause the dilated vessels in the upper head to constrict, which relieves the headache.
Thanks a lot for writing to Dr. Komisaruk Demo, great to know he is studying fMRI's in men and that we are in touch with him.
Thanks Martin. Omega3 caps (sardines and maquerels oil ? )didn't help me. I want to try astaxanthin but it's expansive
I don't want to wait until late 2013 or 2014 before we can get dedicated (NORD-funded) POIS research under way. At the moment, that is the best we are heading for. We've got 2 months to get to our NORD target this year and save ourselves from waiting this long. We've had some very generous donations recently but some of these are to be made over a period of months. I'm certainly no less grateful to the donors for this fact but it does mean the current NORD pledge tally can be misleading as it uses the total that will be donated by 2013, not by March this year. We are still currently not in a good position to make the March deadline this year. To me it looks like we're half way at best.After we reach our $33500 target, it'll likely be some months before a researcher is appointed to work on POIS through NORD. It may be some time after this that work finally begins. I believe I'm right in saying that we really need to make the March 2012 deadline (2 months time) if we're going to see any benefits from NORD funded research within the next two years. There isn't a quick fix. But it'll be quicker if we begin now. Also, things will cost more in years to come. $33500 might not be the minimum required in future years, it might be more. We have some things that help some of us (eg. Niacin, immunotherapy) at the moment. But these are not cures so far or 100% effective treatments. And we still don't know what causes POIS. We have much better theories than we used to and even evidence for some of them but all POIS sufferers are not the same and what works for some doesn't work for others. We need to push this if we're going to help everyone. We need to know what POIS is, what causes it, what varieties of POIS there are and use this to get as close as possible to being cured/ being POIS-free. For us and for future sufferers.2 months is all we have. So far I have pledged $500. On the condition that we make the March 2012 deadline, I'm upping my pledge to $1500. (seriously, no clappy applause gifs for this please, lets just get that total)
