New type of nerve cell in brain. POTSers, take note… and hope

This article discusses the discovery of a new type of neuron in the hypothalamus. 

A new type of nerve cell found in the brain

This specific type of nerve cell handles cardiovascular functions, playing some sort of role in regulating heart rate and blood pressure. The cardiovascular system being the interlocked system  that it is, this presumably also includes force of heart contractions, tension of the vessels, and other autonomically-driven activities.

The autonomic part of the nervous system is supposed to be the ring-master for the automatic functions of life, everything that has an up and a down: blood pressure, heart rate, sleeping/waking, appetite and thirst, and so on. Its dysregulation in CRPS is probably one of the most stubborn problems in treating and managing this disease. Finding a type of nerve that so explicitly  handles one part of that extraordinarily complex set of inter-relating functions is fascinating enough, but the ramifications are tremendous.

Here they discuss it in terms of its relationship to the thyroid, an endocrine organ that’s an important part of those regulatory mechanisms, on the chemical-messenger side. The thyroid drives the creation and balance of these types of nerves; these types of nerves then influence the output of the thyroid. It’s a metabolic two-step, a mutual relationship characteristic of nearly every chemical/physical connection in the human body.

Those who have POTS and other forms of autonomically-driven cardiovascular problems might have a new cause for hope. Being able to separate out that particular set of mechanisms from the rest of the nervous system, at least to some degree, may give them a chance of managing their disease better without throwing the rest of their autonomic functions further off.

Anyone who has been that nauseously dizzy and that weak for that long would be terribly glad of the chance. This is great science, and not just for those with thyroid disorders.

Pain is a pity, but really …

I got a remarkably thoughtless comment from someone on the physician-driven site,
“Everyday is certainly a struggle for people with CRPS because they live in pain 24/7. While there is no cure for the disease, it can be slowed and likely to go into remission if treated early, ideally within three months of the first symptoms.”

This remark was so fatuous and misguided that I found it alienating, but it raised several important issues that do come up — especially in regard to people who mean well but don’t know much about it (regardless of their educational level.)

Here are the main points of that remark:

1. Pain is why people with CRPS are to be pitied.
2. It’s incurable, so don’t go there.
3. It can be slowed or pushed into remission…
4. If you catch it really early.

Those of you who’ve followed me, know what’s going through my head right now… “Where do I even start?”

Not with # 1. We’ll have to come back to # 1. Let’s go in reverse order.

4. “Diagnose it early, ideally within 3 months of first symptoms.” Physicians control diagnosis; patients can only control how they respond to it. Since most cases of CRPS aren’t even diagnosed for YEARS, that’s not a useful remark. Say it at every medical workshop you go to; leave it out of a patient-driven site, because it’s a slap in the face.

3. The remark on remission is slighly confusing.  Remission in CRPS is not like remission in cancer. It’s a fragile state which can revert at any moment over the slightest thing. It’s nothing like a cure. Remission is still possible years on, as the anecdotal evidence indicates.

2. A cure, as they pointed out, doesn’t exist — yet. And, with the wrong clinical focus and a hopeless clinical attitude towards a cure, it’s no bloody wonder.

It can be cheaply prevented in ~80% of cases by 500 mg vitamin C, 3 times daily, for 2 weeks before and 3 months after surgery (or 3 months post-injury.) That’s much more realistic than CRPS getting diagnosed within months, but so few people know about it that it doesn’t happen much.

Result: lots of needless CRPS.

Spread the word about 500 mg vitamin C. It could save lives.

Most people who don’t have CRPS focus on the pain as the reason for sympathy. Everybody has had pain, and the idea of pain is what they think they can identify with…
The pain of CRPS is like nothing else I ever experienced before. Yet I was an emergency nurse, motorcyclist, weightlifter, runner, horse rider, gymnast, martial artist… and a statistic, having endured more than one attempt on my life. (I’ve had an eventful life.) Plenty of opportunities to hurt; always recovered fast.

Yet, despite the often show-stopping pain I now live with, PAIN IS THE LEAST OF MY PROBLEMS. It’s the weakness, autonomia, and cognitive decline that are the real problems.

That’s where the research needs to be.

That’s where the help is needed.

That, honestly, is where the most empathetic and useful sympathy lies :-)

Imagine feeling your ability to think, learn and remember simply dissolving, and there is nothing at all that you can do about it. You can hope it will come back to some degree, and eventually it does (if you avoid everything you’re now sensitive or allergic to, eat tons of antioxidants and greens, drink lots of water, and don’t screw up anything about your life at all — while you can’t remember what just happened, let alone all that you have to do…) but you know there are no guarantees, and after awhile, the repeated gapping starts to add up.

For a brain, that sucks, eh?

Doesn’t that seem a bit more distressing than physical pain? I think so. It certainly has more of an effect on what I can do with my life.

Pain can be pushed through; the weakness, autonomia and cognitive decline are virtually impossible to push through.

Why is that? Because I need my muscles to be able to recover in order to rebuild melting muscles, my autonomic nervous system (ANS) needs to work well enough to let me regain control of my ANS, and I need my brain to work out how to help my brain.

It’s like opening a box with the crowbar inside.

Relentless attention to activity, food and supplements, and state of mind are mandatory for a bearable life — not because of the pain, but because of the weakness, autonomia and gradual brain-death. In order to barely stand my ground, I have to dance as fast as I can.

That’s very hard for most people to wrap their heads around. It seems too hard. But to those of us with chronic CRPS, it’s just another day. We have to manage all that and still somehow keep food in the house, laundry done, bills paid… relationships intact.

This focus on pain, to the exclusion of the more thoroughly disabling issues, has led to a serious misapplication of resources. A lot of lives have been damaged or destroyed because of that willful blindness in the medical and treatment domains. So it frustrates me, especially as a passing remark dispensed from a physician-driven site. (I wonder where their funding comes from… )

Sympathy is a lovely instinct, it really is, and I sure don’t want to discourage it. Though I don’t see sympathy in the remark I quoted above, I have heard people without CRPS express genuine sympathy in nearly identical terms. And they really do mean well. That matters!

There’s a lot to be said for being sympathetic to someone’s actual problems, which may not be exactly what you might expect. This would lead to more understanding, better connections to those who have it, more effective help, and in the end, to more effective care.

This morning, I woke up from a dream where I was running an international conference on CRPS, where 3/4 of the presentations were given by non-physicians: expert patients, massage therapists, PTs, acupuncturists — you know, the people who really know about CRPS, and the stuff that really works for the real problems it causes.

In this dream, doctors could get a lot of CEUs, but they had to spend 60% of their time in non-physician workshops to get them. (How did I come up with 60%?) There was, how shall I put it, a certain amount of fussing about that…

It was a weird dream. Who knows, though, it could happen… It might do people like that staffer at a world of good.


CRPS, ANS dysfunction, and chronic vertigo

The central nervous system is bathed in fluid. This fluid provides a buffer against shock, as well as providing a good medium for the transmission of chemical signals. (Electrical signals are handled by the neurons.) The central nervous system is extremely sensitive to dehydration, which is why headaches are so common: most people are somewhat dehydrated. We consider ourselves too busy to drink water and whizz it out again.

Water is also the main ingredient of blood and lymph. These two essential fluids bring nutrition to the cells, transport chemical signals such as hormones and regulatory signals, and carry away cellular garbage. When there’s not enough of them, that doesn’t happen very well. More garbage piles up in the tissues, aging happens faster, disease trends faster, our muscles get stiffer, it’s harder to recuperate from injuries and illnesses, our sex lives suffer, and we just don’t feel as good.

With that in mind, not having the time to drink in water, process it through, and whizz it out again doesn’t really make sense, but a lot of us are really attached to that idea.

Reality checks

One of the really ducky things about diseases like CRPS, especially when there is strong autonomic involvement, is that normal quantities of fluids (and vitamins, proteins, and other nutrients) are often inadequate to our unusual metabolic needs. It may be possible for a basically healthy person to meet all their needs with three good meals and three or four liters of water per day, but for systems so consistently under siege as those with CRPS, it may be impossible to meet metabolic needs within these (otherwise very reasonable) parameters.

I have several friends with terrible vertigo, due to autonomic dysfunction in CRPS. This isn’t the, “I held my breath too long,” kind of dizziness. This is the kind of dizziness where you can’t keep your feet under you, you feel like you’re going to throw up, and it JUST WON’T QUIT.

The mechanism behind this has only been researched recently. It’s not very well understood. I’m hoping for an informative comment from an expert on this…

What’s happening (partly) is that the vessels, which are directed by the autonomic nervous system, are flopping open too much. This means that the normal amount of fluid in the blood, lymph, and cerebrospinal fluid has to fill a space that’s considerably larger than normal. What you get is a type of hypovolemic shock, where the brain and major organs simply can’t get enough nutrition, oxygen, and garbage collection.

This normally happens on a short-term basis, after some assault on the system; normally, it’s either corrected quickly, or the person dies.

There are very few instances where this happens continuously over time, but with CRPS, some people have to live with it. It can make doing anything impossible, and if you try to imagine, just for 5 minutes, what it’s like to be that desperately dizzy and try to do anything — even get a fork to your mouth without bloodshed — you’ll see what I mean.

Sometimes, these symptoms can be somewhat reduced. There are pharmaceutical and mechanical approaches, each with its drawbacks and benefits. Since doctors (and many patients) tend to think in terms of pharmaceuticals first, let’s start there.

Pharmaceutical management

Whenever you think in terms of disease and pharmaceuticals, it’s important to keep in mind that:

  • Every system is unique.
  • Every system with CRPS is even stranger.
  • Unless you’re a doctor getting a visit from a pharmaceutical rep, there is no such thing as a free lunch. Everything you take in affects your whole system. With our systems under siege, it behooves us to be mindful of our chemistry.

NB: This is not intended to diagnose, treat, or cure any disease. Consult your physician with any questions, and if your doctor can’t give you a credible answer, get a referral to someone who might be able to.

Vasopressors, which can help restrict blood vessel size, have mixed results. They depend on the regulatory system being able to work somewhat, which is problematic in CRPS. Moreover, they have their own side effects, and given what a cocktail of medications most people with CRPS are on anyway, this can be quite noticeable. It has to be handled on a case-by-case basis.

Anti-dizziness pills, such as Atarax, affect the central nervous system and tend to make people sleepy and goofy. They are related to antihistamines and acid-suppressing medications (H2 inhibitors), and for those with hotwired immune systems and the nutrient assimilation problems common in chronic CRPS, they’re not without side effects. Moreover, because they address only the generic mechanism for dizziness, but not the particular mechanism for CRPS/ANS vertigo, they don’t necessarily help in these cases. Also, case-by-case basis.

Some SSRIs, typically used as antidepressants but extremely effective for nerve pain, can also provide support for the ANS. There is additional benefit to the use of SSRIs, because of their assistance with the nerve pain component of CRPS; when they can also improve the autonomic nervous system, it’s a big deal. Naturally, SSRIs being the idiosyncratic category that they are, it can take a few tries to find the one that works best in each person’s system. As I learned the hard way, getting the dose right can be a long and interesting task, given the idiosyncratic nature of our systems.

Mechanical management

Mechanically, it’s possible to increase blood volume by taking in lots of fluids, even if you already drink “enough.” “Enough” is a relative term, and what’s “enough” for a person with a normal autonomic nervous system may be “completely inadequate” for somebody with vertigo due to CRPS.

Blood pressure is a complex system, involving more than just fluid, vessels and the brain. Maintaining electrolytes helps contribute to a healthier fluid balance, and towards that end, sometimes doctors suggest increasing your salt intake. That only raises your blood pressure when you already have a predisposition to high blood pressure, so it may not be obviously useful; however, adequate sodium is important in maintaining renal function and supporting potassium levels.

Potassium is another key electrolyte, along with magnesium (found in Epsom salt), calcium, and bicarbonate. It doesn’t take much; four or five of the smallest grains of Epsom salt, stirred into a glass of water, can make a noticeable difference when you are magnesium depleted. Also, it usually makes the water taste better.

It’s easy to tell when you’ve taken too much, partly because it doesn’t taste good, but especially when it gives you the runs. Less is generally better than more!

Bicarbonate is better managed by eating plenty of vegetables, rather than trying to supplement and get the dose just right. Having an overly alkaline system doesn’t feel very good, either.

Calcium and magnesium are present in food, especially if you’re eating plenty of nuts and leafy greens. If you have CRPS, you really want to eat plenty of nuts and leafy greens! They provide so much in the way of A and B vitamins, antioxidants, minerals (which support cellular processes and regulation), healthy fats (which help your body absorb your nutrients and protect your nerves), fiber, digestible protein (which helps your body absorb the calcium), and so much else of what your body really needs.

Activity, even horizontal activity, even just stretching out gently in bed, provides the body with much needed prompting about how to keep things moving. It keeps your muscles loose, so that your body is more comfortable to live in; it also activates sensors in your joints which communicate with your body’s regulatory mechanisms, and this helps with maintaining blood pressure (one can only hope it helps enough.)

Any movement is better than no movement.

Changes in position should happen slowly, which is terribly frustrating, but it’s going to take as long as it takes. If your body doesn’t get to move, it forgets how to handle itself in movement. This becomes a negative feedback loop.

So, keep moving, even if you’re not moving in any way that the doctor would recognize. Frankly, most doctors are somewhat limited in their ideas of what constitutes exercise. Most of them have no trouble walking from the car to the office, let alone from the bedroom to the kitchen.

Don’t let perfection assassinate your drive towards improvement. Do what you can, and don’t sweat the rest.

  • If you can’t run around the park, walk around the block;
  • If you can’t walk around the block, practice ballet or t’ai chi with one hand on the back of the sofa;
  • If you can’t do that, fire up YouTube and do chair qi gong or chair yoga;
  • If you can’t do that, stretch out gently in bed, and do range of motion exercises. (This is a wonderfully pretentious term for moving each limb all the way up, then all the way down; all the way in, then all the way out.)

There is always something you can do to keep your joints active.

Moving your joints sends a message to your regulatory centers that they need to pay a little more attention to your blood pressure. That’s why it’s important to stay active. Our regulatory systems are screwed up enough; we need to keep them gently tuned, and be persistent about it, even when it seems absurd to do so. The habit of activity will serve you well for the rest of your life.

I’m aware that there are some herbs that have tonic effects on blood pressure and possibly the ANS. I would love to learn more about that.

Assume there is a future, and that what you do, even little things, can change how it goes.

That’s a good general policy, anyway. Especially with CRPS.

While I’ve known all this for many years, applying it to CRPS has been an education. When I’m able to focus a little longer, I’ll put together some references. Meanwhile, any of you who have references, either to support or contradict any of this, would be very welcome to post them in the comments.

I look forward to better science and better medicine for chronic vertigo in CRPS. It’s so thoroughly disabling, yet so thoroughly underrated.
