>I just happened to be come across this post (I wasn't even looking for it) with more info on Amisulpride and the autoreceptors. Ironically the post was written to you. Here's the relevant paragraph:
"I use Amisulpride which is also an antagonist of Dopamines D2/D3 receptors. But at the dose I am taking (very low) it has more affinity to presynaptic receptors (called autoreceptors). If these are blocked then the release of Dopamine gets ENHANCED. So this drug has contradictory effects at low/high doses..."

I may try this down the line but I think my first step will still be the selegiline. If it eventually goes from putting me to sleep to waking me up, then I'll know that it is working. Hopefully it will have some effect on depression sooner.K

Hmm, thats something to consider.
A combination of amisulpride with a
DA drug, might produce a synergistic
effect.Linkadge

Ray,
Here is the info on Jay Goldstein's most recent book. I'm copying part of a recent post by AndrewB:
"One side note: as you know effective treatment for fatigue states depends on the individual. The closest thing I've seen to a 'Rosetta Stone' for figuring out and treating fatigue states is "Tuning the Brain" by Jay A. Goldstein, M.D. All sorts of 'secret' concoctions are spelled out in there and the mechanisms behind why they work when they work, and an algorithm for subtyping yourself so you don't have to blindly try everything. I did like it when I read his lament that he didn't have access to sulpiride, because there was no US drug for dealing with situations of supersensitive DA autoreceptors in the NAc."
I'd really like to read that book. It's not at any of the local libraries yet though.

Could I have read a while back that fish oil can make neuro receptors more sensitive? (I could be confusing it with phosphatidylserine and/or ginkgo - or does this pertain to all of these?) If that's the case for the fish oil or these other supplements, then could I make my hypersensitive dopamine autoreceptor problem worse by taking any of them?

yes it tends to..but only by the effect of maybe "unblocking" receptors that needed to be unblocked..like correcting some resistance possibly. I know the unblocking type effects have been reported by individual users..don't know of any studies on it though.
It is only a positive.

I'm trying to figure out what unblocking means in terms of hypersensitive receptors. Does it mean that it prevents them from holding up too much of the neurotransmitter? In other words, does unblocking them mean that it forces the autoreceptors to push out more neurotransmitter? If so, it would definitely make sense for me to increase my dosage.I think I may have had an incredible insight just now. I was answering a post to JLx and I was talking about fish oil and the fact that I took a large dosage of good quality stuff years ago. I bought the stuff from the holistic doctor's office. At that time I was taking balanced omegas (not just EPO) for a skin rash problem. I didn't know anything about its positive effects against depression at the time. It didn't help at all for the skin problem and I ultimately stopped taking it. Around that same time or possibly a little later (wish I could remember exactly), I started taking Prozac. I got a good response from it for about a month (the only good AD response I've ever had) and then it pooped out. Now I'm wondering if the response I thought I had to Prozac was really a response to the fish oil. Maybe Prozac didn't poop out after one month. Maybe it never worked at all and the poop out was more a response to stopping the fish oil? Wish I knew exactly what the time frame was for all of this. It would probably be easier just to try the fish oil again rather than try to go back and figure out the past. Hmmmm. Lots to think about now.
Thanks Jan!

when you tried tyrosine ..di you try the straight l-tyroine posder ..or say Thorne RESearch l-tyrsoine capsules..something not too mixed with binders, fillers etc.
It made a big difference with me.(the tablets had little effect)
Also did you take the tyrosine by itself early n the morning a least say 30 min b4 any food or even a cuppa.(preferably an hour b4 since you are hypo)..like take it if you get up in the early morning for a toilet break..say 4am or 5am?(that's when I take my first lot med meds)That makes a difference also.

The brand I took was Ecological Formulas (in capsule form) - an excellent brand. I followed the directions as prescribed by Dr. Priscilla Slagle to a T. Still no benefit whatsoever.
If I do try tyrosine again, it will only be the Norival version.

>Hi Ray,
Still going thru old posts I was going to reply to :-)I knew about lyme..a lot of folk on the British thyroid board have been looking at it..the depression is one part of it.
There's a doc in England (or probably a few) who is into treating it I think.
http://forums.about.com/ab-thyroiduk/messages?msg=2092.1 (I think)
It's a long treatment ..like months or years..and I don't recall any real successes but maybe I didn't follow it enough...or maybe the treatment isn't over as yet.I tried doxycycline for 6 weeks myself this year..continuing for a few weeks when was in Britain. (my excuse was a malaria preventative, when I was in a high malaria area) I felt terrific on it after a while, but in the end my teeth seemed to be going brown and cracking..not sure if it was related or not..but I stopped.
Ya know what..the only time in my life I had a clear nasal passage was when I was in Britain..so is this the doxycycline or maybe just the eucalypts? Was interesting anyway. I was put on antihistamines at birth to allow me to feed :)
Nasal passages reblocked about 1 hr after I landed back in Oz.
Re Strep..yes, I always suspected it would..I personally blame the "don't give an antibiotic until we see if you can fight it doctrine"..(gee penicillin is all that is needed )
Could rave on about what this has caused for a long time..but I'm sure everyone would think I'm nuts.(hmm guess they already do?)
I've been waiting for medicine field to wake up..I suspect they might be a little?also similar thing for psoriasis, maybe a lot of autoimmune problems..works similar to rheumatic fever...
hey that doesn't exist in our modern society? It still exists in outback Oz amongst aboriginal communities, and they have tried vaccinating all the kids with penicillin injections ..only one problem with this..the injections are painful and after the first couple the kids wake up and disappear into the bush when they see the docs coming...docs/researchers haven't heard of a reward system it appears.
If the do come down with rheumatic fever..from the strep throat, then they get treated with penicillin shots every month for years to prevent any outbreaks and it seems to work for those willing to undergo the injections.In my theory at least it works similarly.
Somehow the bacteria must allow the viruses etc to be worse..and when I go to the docs I just get ..its a virus..nothing I can do, and yet, if I treat with penicillin within the first day or two, I don't come down with any virus or depression..or worsening of autoimmune, daughter doesn't break out in psoriasis..don't get the very high temps or the arthritic like pain(with her it was called psoriatic arthritis) thru body or the depression...nor isn't this strange??
If untreated it last months.I know bacteriaphages aren't supposed to get humans ..but would this maybe be what is happening? or is it that our immune system just gets weakened?
All I know is that if the bacteria in the strep throat don't get the penicillin , and the temp goes high ..then it all starts. With my daughter it all began at age 10- with very high temps for a week or so..then the rashes started..then the arthritis etc..then they said it was arthritis. After the first time, comeback outbreaks(called its just a virus by docs) happen fairly often..and if immediately treated with penicillin all is fine,, if not..the spots, aches and pain, fatigue, depression flares again..lasts months....no obvious infection there..and yet the penicillin works to prevent it.
By the time the strep throat looks bad enough to treat..its too late.and I know we all have strep there all the time.
I've put myself on penicillin about 3 times this year..and stayed well, instead of the months of illness...including the depression. Wish I could qualify for the monthly injections for a trial for a couple of years.
Well all this is only my (probably wrong) opinion and what I've observed over the past 8 years or so.

Hi Kara,
Have been taking hawthorn for the last couple of days and get a brain effect similar to when I eat chocolate or have DLPA - I notice it's a phosphodiesterase inhibitor like chocolate too. Phosphodiesterase inhibition should raise Cyclic AMP - would that be good or bad for you?
"autoreceptor regulation of tyrosine hydroxylase must occur through a decrease in cyclic AMP levels."
http://molpharm.aspetjournals.org/cgi/content/abstract/29/6/561
Uncoupling of tyrosine hydroxylase sounds like the metabolic pathway has been disconnected - low biopterin has been mentioned in conection with uncoupling - and folate has been mentioned in studies to resist uncoupling and biopterin degradation.
When biopterin becomes 'uncoupled' from tyrosine hydroxylase, it can produce free radicals such as hydrogen peroxide.

>Dunno if hawthorne would be good for me or not. From the article you attached it seems that Cyclic AMP activates the tyroxine hydroxylase (which I'm assuming helps to create more dopamine). In the long run that's good I think because you want to flood the synapses with dopamine to force downregulation. The article is too far over my head to say for sure though.
Thanks for thinking of me. If you find out anything more about it, please let me know.

H2O2 is hydrogen peroxide - I was concerned that tyrosine hydroxylase could make a potent free radical instead of L DOPA if it didn't have the right nutrients to help it function. cAMP is something that is increased by chocolate and PEA (and hawthorn) and is implicated in the swithching on and off of dopamine metabolism within the cell. Opiates such as morphine (and wheat and dairy opiates) first raise it and then lower cAMP - the lowering of cAMP is thought to cause serotonin and dopamine to fail leading to desire for more opiates. Just had a test from an autism lab - I have unusual tryptophan by-products in my urine that suggest I'm making opiates from wheat and undermining my serotonin metabolism.
There is a possibility that low cAMP could be what brain fog is - not sure as all the info is a bit sketchy!

Thanks for the explanation. It's fascinating that you're able to get that kind of information from the lab. If you're not metabolizing serotonin correctly, wouldn't you be feeling very depressed or does this just refer to the serotonin in the body and not beyond the BBB? If you don't mind my asking, how does your autism manifest? I would never think that was an issue of yours from dealing with you on-line. If you don't wish to discuss it that's fine too.

The unusual by-product of serotonin is called IAG and is claimed to be increased by opiates from wheat - other people make opiates from dairy and what's interesting is that opiates have an effect on the presynaptic control of dopamine...I don't claim to understand any of it, but it's interesting that wheat and dairy in some people could disregulate dopmine producing neurons.

Probably more an aspergers type of person - on a bad day I feel emotionless and want to be alone! The researchers say that people with chronic fatigue and gulf war syndrome often have the same profile.

As well as opiates, gaba, glutamate and acetylcholine appear to have an effect on presynaptic dopamine receptors - are they the same as autoreceptors?Just started reading a book called "prozac backlash" It talks about SSRIs inhibiting dopamine, and so dramatically reducing female hormones. I wonder whether autoimmunity increases with SSRIs, what do you think?

The unusual by-product of serotonin is called IAG and is claimed to be increased by opiates from wheat - other people make opiates from dairy and what's interesting is that opiates have an effect on the presynaptic control of dopamine...I don't claim to understand any of it, but it's interesting that wheat and dairy in some people could disregulate dopmine producing neurons.

>Ray,
Is there no end to the things that can disrupt dopamine production or transmission? It's overwhelming (and I'm sure we've barely touched on all of the possible factors involved). I must sound like a broken record on this topic but I'm tired of trying to figure it all out. Right now I just want to take a pill and make the problem go away!

The researchers say that people with chronic fatigue and gulf war syndrome often have the same profile.I often want to be left alone. I've always needed a lot more alone time than most people. I guess the difference is that I don't feel emotionless.

My understanding (and hopefully someone will correct me if I'm wrong) is that if the receptors are presynaptic, then they are autoreceptors.
> Just started reading a book called "prozac backlash" It talks about SSRIs inhibiting dopamine, and so dramatically reducing female hormones. I wonder whether autoimmunity increases with SSRIs, what do you think?There's been some interesting debate about the validity of Glenmullen and Breggin's books on the main board. I'm a bit skeptical of some of their work. The SSRIs inhibiting dopamine is dead on though. Some people seem able to take SSRIs indefinitely without this result for some reason but others of us aren't so lucky. I think that years of SSRI usage may have contributed to my condition now. I strongly suspect that these meds had that negative affect while I was taking them. Now that I am no longer taking them I don't know if they are still a factor in my condition. Unfortunately I can't go back and see if I would still be this anergic had I never taken an SSRI so I will never know for certain how much of a long-term inpact they have had.
I hadn't heard of SSRIs reducing female hormones. That wouldn't surprise me either. I remember that when I would start on an SSRI or go off of one, I would have disruptions in my menstrual cycle. I told my pdoc but she said there's no relationship. I told her I didn't believe that because my body was telling me otherwise and that I thought that in time this would come out. (However, some temporary disruptions in my cycle doesn't necessarily mean that they lowered the hormone levels significantly and over the long-term.)
In terms of autoimmunity, since decreasing hormone levels are associated with more autoimmunity problems, then it does follow logically that SSRIs could impact autoimmunity (if, in fact, the SSRIs do lower hormone levels signficantly). I did develop Hashimoto's while I was on Effexor. Hmmm... Now what was I saying about not buying Glenmullen's theories???? Still, I'd recommend checking out the debate on his work on the main board if you get a chance.

Cofee quickly raises cAMP within the cell.
Coffee has a powerful anti-brainfog effect.
I've had some good sucess with low SSRI doses and coffee.
