Norepinephrine vs. Dopamine

Posted by KaraS on August 2, 2004, at 16:47:03

Forgive me if I've asked something like this before but I'm trying to figure out whether I need noradrenergic and/or dopaminergic assistance. How much is each of these involved with energy and motivation? From the reading I've done it seems that they overlap quite a bit (unless I'm interpreting what I'm reading the wrong way). How does one know if they need more of one (or exclusively one) rather than the other? Is there any way to tell other than through trial and error of various meds?

I'll outline the current theories for you; maybe someone else can offer some recommendations about meds.

Gary Aston-Jones thinks that "the phasic mode of LC activity may promote focused or selective attention, whereas the tonic mode may produce a state of high behavioral flexibility or scanning attentiveness." Note that the LC is the locus coeruleus, the location of most norepinephrine neurons in the brain. See http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=10560036 and http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12802890

Several researchers such as Kelly Berridge have suggested that dopamine is involved in certain types of motivation. Berridge says that dopamine mediates incentive salience, or wanting incentives. Salamone and Correa (2002) think that dopamine might be involved in activational motivation. They define this as "activation for initiating and sustaining instrumental actions; tendency to work for food." See http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9858756&dopt=Abstract and http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12445713&dopt=Abstract and http://www.neurotransmitter.net/wanting.html

Thanks Shawn. I haven't read your citations/abstracts yet but from what you said, I think to put it crudely, the NE provides focus (and energy of course because it's noradrenalin) while the DA is motivational. That makes a lot of sense. My only question now is why then would the stimulants be effective for ADHD? Maybe that will become clear once I do the reading.

Well, this is just speculative on my part, from my experience with noradrenergic drugs (particularly Strattera) and the dopaminergic Provigil: Strattera did promote focused attention, but did not hook into the motor system very well. I felt like my mind was perfectly clear, but felt like an 'observer' at times of my state. The attention was there but the behavioral control was not. On Provigil it is markedly easier to direct my actions physically. This makes sense as dopaminergic drugs are used to combat Parkinson's which is a disorder of motor dyscontrol. Children with ADHD exhibit disinhibited movement. there are many variants of ADHD but there is clearly an interaction with the motor system that the DA drugs treat more effectively, although the NE drugs treat the cognitive symptoms to some extent by promoting attention itself.

This is more wild speculation, and those more knowledgeable about these things are free to object, but I found that nortriptyline has SOME effect on the motor system (reflected in a sense of 'slowing down' so I could use my attention to direct my actions) while Strattera had no effect on this at all. I wonder if this reflects a difference in the regional actions of the drugs, a claim Lilly (and my pdoc) were pushing. Provigil 'feels' more like nortriptyline than Strattera, because instead of promoting cognitive clarity, it promotes goal-directed action (which my scanning of the abstracts indicated was consistent with a DA effect). Provigil of course is much stronger than nortriptyline in this regard.

So in terms of energization and goal-directed activity: Provigil>nortriptyline>Strattera.

z,
Could you please clarify more what you mean by "On Provigil it is markedly easier to direct my actions physically." Do you mean that it's easier to translate your intentions into action - or am I way off here?

http://www.neurotransmitter.net/adhdne.html
http://www.neurotransmitter.net/adhdgenetic.html

One hypothesis about stimulants such as the amphetamines is that they increase the number of spontaneously active dopamine neurons in regions such as the ventral tegmental area (http://jpet.aspetjournals.org/cgi/content/full/297/2/746 ). A possible result of reduced dopamine function in ADHD could be an intolerance of delays (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=14624804&dopt=Abstract); this is consistent with the view that dopamine is involved in activational motivation. In neonatal rats that have had their dopamine neurons lesioned, dopamine D4 receptors increase in number and perhaps induce hyperactivity (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11927187&dopt=Abstract). The dopamine D4 receptor and other dopaminergic genes have been associated with ADHD. In general, dopamine may be involved in hyperactive-impulsive behavior while norepinephrine may be more involved in the cognitive aspects of ADHD; however, there may some overlap. Thus, a significant amount of evidence supports the use of stimulant drugs in a subset of the ADHD population. Future research should help to identify tests that could determine whether a person with ADHD would benefit most from a stimulant or non-stimulant drug.

That makes perfect sense - those with pure ADD would need the NE but the ADHD would (also?) need the DA D4 activity. I have my reading cut out for me!!

I think I need both noradrenergic and dopaminergic assistance. I definitely need help with focus and concentration but I also need the motivation badly.

Thank you.

MORPHINE- and derivitives for depression

In reply to Norepinephrine vs. Dopamine, posted by KaraS on August 2, 2004, at 16:47:03

Excellent question!

The ADD stimulants have a significant NE component (as well as the primary dopamine action) so it's pretty hard to sort out. There aren't many pure dopamine medications, even cocaine & crystal meth work on NE to some degree.

In rough terms NE is the tense adrenaline, stress, fight/flight system and dopamine is the pleasure/reward system. I have no clue how concentration fits into those physical body descriptions. Motivation versus activity makes sense though. I wonder which effects obsessive behavior (which I associate with adrenaline/NE) but it's a motivation (avoidance) powered thing as well.

Ack, I'm confused now. Gotta read up on those links and will get back. As always, there is a counterintuitive factor where too much or too little gives the opposite effect.

The basic contradiction is that NE sounds more stimulating and DA more euphoric/sedating but the traditional mixture is something like 80% DA, 20% NE to get what we call a stimulant.

The pure DA meds can make people jittery but 'jittery' is something I'd be more likely to associate with adrenaline.

You should try some Desipramine to get a feel for an NE increase with less side effects, you can add it to any AD that you are taking. The NE boost I get from Nortriptyline gives me a feeling of alertness & a more awake feeling. Dopamine drives motivation via reward, doing or achieving something gives a natural dopamine boost which motivates you to do it again, this is why the stimulants are so addictive & a trap. Personally I think that tampering with dopamine should be avoided unless you actually need it for ADD problems.

Cheers,
Panda.

Hi Z,

It's intersting that you say that about Nortriptyline. The info I have is all the TCA's are weak but measurable Dopamine reuptake inhibitors & that Nort is the stongest of the bunch.

It is not necessarily true that you can add desipramine to any antidepressant. You shouldn't add it to an MAOI, and if you are particularly sensitive to medication combinations and/or if you have a genetic polymorphism for some of the cytochrome P450 enzymes, especially the 2D6 enzyme, you probably could not add a tricyclic to any antidepressant. Some people have no problem with polypharmacy; others are extremely sensitive to drug combos and can get very sick or die from indiscriminate mixing of medications. It is best that any attempts to mix medications are done under a doctor's supervision.

You can actually add some TCA's to MAOI's. If the TCA isn't a serotonin reuptake inhibitor then it will actually improve the safety of an MAOI. Desipramine, Nortriptyline, Doxepin & Trimipramine can all be added to an MAOI depending on if you need stimulating or sedating. Clomipramine & Imipramine are dangerous due to risk of serotonin syndrome & I would not risk Amitriptyline either although you can find it combined with an MAOI in a pubmed search.

That's true, but I wasn't suggesting starting desipramine at 100mg either. Starting at 25mg would be fine.

I am aware of the MAOI+TCA combos that you mention, but they are not for everyone. In some cases, even low doses of TCA do not work. These combinations should be done with great care under a doctor's supervision.

I don't think we should assume anything. I know there is at least one poster on this thread alone who has no medical insurance. She is stuck in the Catch-22 of being too sick to work, so she doesn't have insurance, but she can't get the medical help she needs to get well until she has a job that provides insurance. She is in a desperate situation, and I'm concerned that she may act out of desperation and do something dangerous. And, if you think about the number of people without insurance, there are probably hundreds of other readers in the same predicament. The practice of obtaining medications illegally will go on, regardless of Dr. Bob's prohibition against broadcasting it.

I am the aforementioned desperado who is stuck in that Catch-22. I really appreciate all of your advice and concern. At least in my case, you don't have to worry. The only medication I am taking right now is a minute amount of Effexor. I should be off of it entirely soon. The things I'm going to be trying now are a couple of brands of Rhodiola and then, separately, Perika (SJW). All of the info I'm gathering now is for future reference.

I think you may be being a bit too strict. If we all gave out advice adhering to the rules as you see them then the only advice we could give or get would be to go seek medical advice from an actual doctor.

I also seriously doubt anyone ever died from taking 25mg of Desipramine, IMHO.

I think each poster decides where to place the fine line he walks. I move mine around from time to time.

It can be argued that even the advice coming from an M.D. might not be of sufficient value to submit in a forum such as this when so little patient information is made available as would be necessary to acquire in a proper medical interview for the sake of making diagnoses and treatment decisions.

I've been pretty conservative lately with giving suggestions - the "do no harm" thing, I guess.

It's important to know whether we're talking about depression or ADHD here. Ritalin expert Dr. Patrick Cosgrove thinks, in a nutshell, that ADHD is ALL about dopamine and that many ADHDs who are dejected from their disorder are misdiagnosed as depressive, and put on SSRI's which do little or nothing for them.

In reply to Norepinephrine vs. Dopamine, posted by KaraS on August 2, 2004, at 16:47:03

Don't lose sight of the question of balance. I don't think that most of the mood disorders are caused by a simple deficiency in one or another of the neurotransmitters, so much as an imbalance of the ratios between them. My 'theory' is that that's why trial and error is so important in finding the right med or combo for each of us.

That said, Sad Panda has a point about dopamine being involved in the reward system, and it's involved in motivation. Norepinephrine is involved in the whole system that ends up producing adrenaline, so I would associate it with energy. (And, since I'd like the motivation to use the energy that I would like to have, I'd look at something that maybe tweaks both... But I'm not only not a scientist, I couldn't even play one on TV!)

The Terrible Trio of neurotransmitters associated with mood disorders -- serotonin, dopamine, and norepinephrine -- are all monoamines -- so one of the monoamine oxydase inhibitors will hit all of them. If you're interested in getting more narrow in the target you're gunning for, I agree that desimpramine or nortryptyline are good bets.

In general, though, I think the trial and error process will give you the best results. It's frustrating, and there are very few tests that can help guide the choices made, and very few doctors who bother with any of those tests, but the only way to find out if you'll benefit from a specific drug is to try it. And, while the different neurotransmitters do have different effects, which makes you think (well, makes me think) that your symptoms can guide the choice of a target, the reality is that behavior and emotions are too complex to be attributed to a single cause. My own lack of energy, for example, when depressed, is actually an overflow of anxiety -- which you'd think would give me energy, right? Not all of it is intuitive.

(Then again, I tend to think that serotonin gets too much attention -- those other molecules are so cute! We oughta be petting them, too, before they start to sulk.)
