Why don’t we doctors know much about Sleep?

We all do it. We spend 1/3 of each 24 hours doing it, why?

We all know we feel terrible the next day when we don’t sleep well. What if we felt that way every day?

How important is it to our patients? Why don’t we learn about it in residency? Dr. Perkins has just shown you why it’s

particularly important to the field of Cardiology.

Features of my patients’ sleep disorders:

(They don’t have fat necks!) Young, healthy headache sufferers. Some of them get too paralyzed; apnea

results. Some are not paralyzed enough; their legs or arms or jaw moves.

Usually both features are present to some degree.

Do they have two separate sleep disorders? Why would young, healthy people have

not one, but two sleep disorders? Could it be one problem producing both features?

How could we model a paralysis switch that when it malfunctions causes both findings?

All the abnormal sleep studies have 2 common

features: We could view all of the abnormal sleep

studies as having one or both of : problems with the timing of sleep, (falling into appropriate stages)– or--the paralysis of sleep.

Both of these features are controlled by the posterior brainstem nuclei and are heavily intertwined.

All of the sleep disorders can be viewed as different facets of these two “switches” not operating correctly.

Our genetic diseases start to Our genetic diseases start to show up when our repair show up when our repair

phase begins to failphase begins to fail We are all dealt a genetic “deck” the day we

are born. That means every person who sees me with

daily headache has had that genetic tendency since day 1. Why does it start in one person at 15 and another family member at 72?

While we sleep we strengthen or “shore up” every one of our existing genetic weaknesses. When this sleep process fails we can only manifest the “diseases” we have genes for.

But that also means the brain/body still knows what to do but it hasn’t had the time in sleep to make the proper nightly repairs.

Page 24: Vitamin d and cardiology

Using Sleep as Therapy There are some genetic disorders, like

cerebellar ataxia, where we know the gene mutation but we have no treatment.

I learned that if I could treat the sleep the symptoms improved.

This may mean that neurologic “degenerative” diseases are only inexorably degenerative if the sleep remains non restorative. It may also explain why some people get better and we don’t know why.

These same concepts apply to the heart, the blood vessels, and the autonomic nervous system.

The sleep connection is the only new observation, everything else was described 30 years ago but you didn’t learn about it in medical school. Why is that?

When the word “vitamin” was applied to this chemical it became overlooked by Medicine and has not been taught to those of us who should be conveying this to our patients.

Over the last 30 years all of the basic science observations to support Dr. Stumpf’s theories have been published. Why don’t we know about these articles?

They’re in the Nutrition Journals, the European Endocrine Journals, and just the last 5 years, our medical journals.

Why did they call it a vitamin if it’s not one?

Why the “D2” and “D3” numbers ? The original rickets model was established by narrowing

down a rat’s diet until their bones got osteoporotic. Oops, rats are nocturnal animals, they don’t go out in the

sun. In order to become nocturnal they had to evolve a D receptor that could use the D found in food. (Vampires apparently use our D.)

The first chemicals found that corrected the rat’s bone disorder were from fungus on grain. They were named vitamin D1 and D2. They appeared to be vitamins, they were, in fact, in the food.

Unfortunately what we make on our skin is D3, a different chemical. That chemical may have different effects at different D receptor subtypes within the body. Every non nocturnal animal on this planet including man makes and uses D3, and it’s not in the food anywhere. It is not a vitamin.

D2 may have variable effects in different species and different individuals. In my patients it seems to worsen the sleep. It may act as a partial agonist at some sites, partial antagonist at others.

Vitamin D and lipid/cholesterol

Simvastatin does not affect vitamin D status, but low vitamin D levels are associated with dyslipidemia: Results form a randomised controlled trial. Int J End 2010 Article ID 957174 6 pgs. These findings do not support a pharmacologic effect of statins on vitamin D status, but do suggest that vitamin D may influence plasma lipid profile and thus be of importance to cardiovascular health.

My personal feeling is that we’ve developed statins over the last 30 years to treat an epidemic of high cholesterol that has arisen due to the pandemic of vitamin D deficiency.

I do not have enough proof to suggest that you should use D to bring the cholesterol to normal, however I do want to suggest that you watch for this possibility.

Page 52: Vitamin d and cardiology

Epidemiology is fine. What about treatment trials?

OK so they’re seen together. Lets see the vitamin D cure the disease.

VITAMIN What’s the right dose? HORMONE What’s the right level? What’s the dose to get to the right

level? This is the hard part. Why is the sleep observation so

pivotal?

Page 53: Vitamin d and cardiology

Sleep is the cure for Cardiovascular Risk Factors Dr. Perkins just showed you how correcting the sleep has

profound effects on the multiple cardiovascular risk factors. The cure is the sleep, not the D. CPAP is one way, D perhaps

another. And if it’s a deficiency state why not try Rx that first?

The curative effect is not D, it’s a perfect D level producing restorative sleep every night. Too high D makes the sleep disorder return 60-80 appears to be the normal range.

Normal sleep, night after night, is what cures the body.

Presumably people who live outside get to 80 in November and fall by 10 pts a month during the winter to 50 in March or April.

Lower than 50 appears to bring on the sleep disorder.

Vitamin D Toxicity and why the FDA’s not crazy

All of the “toxicity” refers to hyper calcemia but most of my patients had “toxicity” symptoms way before the calcium went up.

In most patients the symptoms of fatigue, pain and poor sleep start to return above a level of 90-95. The movements in sleep come back leading to pain on awakening again.

THE SLEEP DISORDER COMES BACK with a too high D just like too low D.

As with every hormone: go too high things go wrong, go too low things go wrong.

Page 59: Vitamin d and cardiology

Vitamin D Toxicity and why the FDA’s not crazy

This is not only a hormone, it is a hormone with a narrow band of normal and it changes in each person from month to month and year to year based on sun exposure and skin type.

How could the FDA possibly recommend a single dose for all Americans living from Florida to Alaska with very divergent skin colors and lifestyles without screwing everyone up?

They wisely chose to recommend a tiny, tiny dose, i.e., not enough to screw anyone up.

This chemical should never be supplemented by the government, it’s as odd as putting testosterone or estrogen in the milk.

It should never have been over the counter so that we’re not sure how much is in the non regulated pills we’re taking.

The D is not the only sleep chemical, dopamine runs

the sleep The single group that has terrible sleep studies

but deny being tired in the morning are the Parkinsons patients.

Many, many of your cardiology patients in their 60-80’s with A fib are these patients. They all have low vitamin D’s.

They also have a dopamine deficiency that magnifies their sleep disorder because dopamine runs the sleep.

If you find a B12 <400 likely the D is low causing this. Always replace both. The daily B12 pills are better.

If they’re not better when their D and B12 are normal send them to me to fix the dopamine.

hormone deficiency Young women who have just had a few babies and come

in to the ER with chest pain and rapid heart beat and you can’t find a cause; Check the vitamin D (and B12) level.

The babies suck up mom’s vitamin D and it never gets replaced because prenatal vitamins have 400 IU of vitamin D.

They see me for headache but many of them have also seen you for what was called “panic attack” and is really something going on in the heart. Atrial D receptors? A PFO that is opening?

Young people with unexplained valvular disease or cardiomyopathy may have vitamin D deficiency always look for it and treat it first.

This D has something to do with high CPK’s from statins. There are vitamin D receptors in the anterior horn cells and the complaint of “weakness” is often in the background in D deficiency.

Page 63: Vitamin d and cardiology

Other supporting factors D hormone has other cofactors that are

necessary for its action so I usually give a multivitamin also.

B12 helps the sleep and should be >500. If it’s below 500 I supplement with 1000 mcg per day as well.

Iron is a cofactor to make dopamine and should be supplemented if low also.

With higher D doses if leg cramps occur or headaches worsen give sunflower or pumpkin seeds as a magnesium source daily. OK, so that does sound a bit like a vitamin wacko, sorry, (Dr. Fanous taught me this.)
