Dr. Bob: If you've got a sleep problem, it can be
fixed. We've been talking about routine sleep, about the stages
of sleep, about how to start off getting a good night's sleep,
and now we're going to talk about sleep disorders. Let's go
right to people that have problems with their legs jerking.
What do you call those problems and what do we do for them?
Dr. Barker: There's "restless legs" which
is the waking part of this phenomenon, the person feels disagreeably
uncomfortable sensations in the legs. That the sensations
occur while you are at rest is key to this type of problem-it
is usually worse when you get into bed at night. But some
people will have these sensations in the evening or earlier
in the day, too. The sleeping part of this disorder is called
"periodic leg or limb movements," where about every
30-40 seconds (when this starts up in the night) they'll get
a little bicycling movement usually in the legs, sometimes
in the arms. They don't know they are doing it but a bed partner
may because it disturbs their sleep.
Dr. Bob: I would imagine their bed partner would say,
"What in the world are you doing?"
Dr. Barker: It can become very annoying. Occasionally
a bed partner isn't aware of it because it can be fairly small
in some people.
Dr. Bob: Are these common problems-periodic leg movement
or restless leg?
Dr. Barker: It's very common. You'll see it in up
to 40% of people by the time a person reaches their 70's or
80's. We don't have to treat all those people. Sometimes it
does bother their sleep so we treat it if it's interfering
with sleep, either their own, or their bed partner's.
Dr. Bob: And, tell me, how do you treat it? What's
the medicine?
Dr. Barker: Yes. We know that it's due to low dopamine
in the brain in most cases and so there are medications to
replace that. Requip and Mirapex are two of the most frequently
used and we know it's also associated with low iron levels
so we are often checking that and using iron replacement.
Dr. Bob: Low iron level. Now, why would low iron level
have anything to do with it?
Dr. Barker: Well, I just mentioned dopamine being
low in this condition and iron is very important in the production
of dopamine in the brain. So, if your iron is low, you can't
make as much dopamine which can result in restless legs or
leg movement.
Dr. Bob: And those two medicines again?
Dr. Barker: Requip and Mirapex.
Dr. Bob: Requip and Mirapex. Now, let's go to obstructive
sleep apnea. First let's start with snoring. Is snoring a
sleep problem?
Dr. Barker: Well, snoring itself is often more of
a problem for the bed partners than the patients themselves.
But snoring is never normal. I think that's the key point.
It's not OK to snore. Lots of things will cause snoring but
one of the most serious problems that cause snoring is, of
course, sleep apnea.
Dr. Bob: Now, what really is sleep apnea? You hear
it, but-really, what is it?
Dr. Barker: We're talking really about obstructive
sleep apnea where there is a narrowing or a collapsing in
the upper airway, the throat, or the upper neck area. So,
it blocks the flow of breathing while the person is asleep.
Dr. Bob: Is there blockage where snoring occurs? Where
does snoring occur?
Dr. Barker: Yes. We think it comes from the area where
the tissues come together and while they are together, it
creates the noise.
Dr. Bob: Now, how do you know if you've got obstructive
sleep apnea? What if somebody doesn't snore-can you have it
without snoring?
Dr. Barker: Yes and that's a very good point because
10-20% of people with obstructive sleep apnea don't snore.
Not breathing can be very quiet too.
Dr. Bob: Oh yes, it can be very quiet. With snoring,
if somebody has obstructive sleep apnea, what do you listen
for? How do you tell if it's sleep apnea if somebody is a
snorer? What's it like?
Dr. Barker: Yes, well, if somebody is simply a regular,
loud snorer, right there's a sign that they may have sleep
apnea. So, sometimes you need to go on into the testing. Or,
if the person has been observed to have their breathing stop
at home, that's actually when apnea is occurring. Then there's
an extremely high chance, of course, we're going to also diagnose
it on the testing. But you have to be careful because sometimes
people have apnea at home but no one actually sees the apnea
happening.
Dr. Bob: How long are the apnea periods where somebody's
not breathing? Does it last a minute and a half or ten seconds
or two seconds?
Dr. Barker: Usually we'll see it between 10 and 30
seconds.
Dr. Bob: 30 seconds?
Dr. Barker: Yes. 10 seconds is kind of a minimum for
it to really to be an apnea, it really takes about that long
before we start to see the oxygen drop so that's really the
important aspect of this.
Dr. Bob: What triggers the patient to start breathing
again if they stop for 30 seconds?
Dr. Barker: Yes, the brain starts to notice the drop
in the oxygen level and will cause an arousing or a brief
awakening that rejuvenates the breathing again.
Dr. Bob: Now, I'd love to spend another 30 minutes
on this right here. When you do a sleep apnea test or when
you do a sleep study, how many times will people have apnea
per hour?
Dr. Barker: Yes. Well, if it's mild apnea it can be
between maybe 5 and 15 times per hour. Moderate sleep apnea
may be 15-30 per hour, and over 30 per hour is severe. And
that criteria has tightened up over the last few years. We're
realizing more and more that even mild obstructive sleep apnea
needs to be treated, even down in that 5 per hour range in
some cases. It's like treating diabetes or hypertension or
anything else
the earlier we catch it and treat it, the
more we prevent long-term complications.
Dr. Bob: What are the long-term complications? Why
do we need to treat this?
Dr. Barker: Well, this is a type of smothering. The
oxygen fluctuates at night and it greatly increases the chances
over the years of developing hypertension, heart disease,
strokes and diabetes.
Dr. Bob: Actually that's one of the causes of high
blood pressure, isn't it?
Dr. Barker: Yes it is.
Dr. Bob: I would like to talk more about the illnesses
like heart arrhythmias that you can have as a result of sleep
apnea. Can heart attacks be caused because of sleep apnea?
Dr. Barker: They actually can. You can, of course,
get a heart attack or a stroke from a blocked artery causing
low oxygen to a part of the body but you can also get low
oxygen from obstructive sleep apnea and it can result in a
stroke or heart attack.
Dr. Bob: How do people know if have sleep apnea? What
are their symptoms that they have during the day. I think
this is very important.
Dr. Barker: Yes, yes, because most patients with apnea
don't know they're necessarily having trouble at night. They
often say, "I sleep great," you know, but they are
often tired and not rested when they wake up; more tired or
sleepy through the day with a loss of energy level; often
more moody; have more difficulty concentrating; poor short-term
memory. These are the major signs.
Dr. Bob: And the treatment that we have for obstructive
sleep apnea-is there good treatment?
Dr. Barker: There really is now and it's ever expanding
and improving for us.
Dr. Bob: When we come back, we're going to take a
little bit more time talking about those treatments for obstructive
sleep apnea. Is it a C-PAP? Is it something like a prosthesis
for the mouth? Are there new medications that we can use?
We're going to be talking about that. Stay tuned.
Dr. Bob: I'm having such a good time. We're talking
with Dr. Rosanne Barker, board-certified Neurologist. We're
talking about sleep problems and now we're on sleep apnea
which can be a cause of headaches in the morning, can be the
cause of high blood pressure, can be the cause of heart rhythm
disturbances, and even maybe heart attacks. We've got to talk
about the treatment. Rosanne, let's go into the treatment.
What are the treatments of obstructive sleep apnea?
Dr. Barker: Well, basically the treatments are either
to widen the airway or add support-these are surgical options.
There is using an oral appliance, a mouth piece, or there
is C-PAP, Continuous Positive Airway Pressure. Weight loss
may be helpful but it is not one of the main treatments.
Dr. Bob: "Continuous
." -- what was
that called, C-PAP?
Dr. Barker: Continuous Positive Airway Pressure.
Dr. Bob: Now what is that, the C-PAP? Tell me about
C-PAP.
Dr. Barker: The C-PAP device itself is basically a
very small, fancy little fan or air compressor that pulls
in room air and pressurizes it. It hooks up through a tube
to a mask that's worn over the face at night and delivers
that air pressure into the nose, goes down into the upper
airway and acts like an air pressure splint in this region
to add just enough support to keep the airway from collapsing
through the night.
Dr. Bob: When you tell people that you're going to
put them on a mask that blows air down into their throat,
what do they say?
Dr. Barker: Well, I think more and more people are
hearing about it but, luckily, as a result of a lot of research
and development all of this has gotten easier to wear. We
have a very high success rate. We have a 90% long-term usage
rate in our sleep center with the support that we can give
to people.
Dr. Bob: Does everybody have to have a different shaped
mask?
Dr. Barker: There are different styles. There are
different shapes. There are different fittings that we can
use and even, I didn't bring them, but things that go right
in the nose instead of around the nose. So, we have a lot
of options now.
Dr. Bob: I've got to tell you a story. I have talked
with patients that are on C-PAP for obstructive sleep apnea
and I ask them, "How did you ever go to sleep?"
And they say, "I didn't think I could, and then all of
a sudden I woke up the most rested I have ever been in my
life." Do you hear that frequently?
Dr. Barker: Yes, because we're only giving this to
people that really need it and so therefore it does the job
for them and they feel great. I like to say people start out
using it because we discuss it with them, and they understand
why they are using it for this dangerous condition. They keep
using it because they don't want to go back to feeling like
they used to.
Dr. Bob: And you mentioned one other thing. You mentioned
about an oral prosthesis. What are you talking about?
Dr. Barker: An oral appliance. Starting about 10-15
years ago lots of people were inventing devices, mouth pieces
that would go into the mouth and would hold the tongue or
the lower jaw more forward and keep a wider breathing space
open behind here. And one that we like very much now is called
the "Klearway," spelled with a K, Klearway, one
word. We like this because it has been heavily researched
and used in thousands of patients and we have hundreds of
patients using it and doing research with it. But it holds
the lower jaw more forward and is highly adjustable, with
44 different positions. We can actually get 88 positions using
an extender a quarter of a millimeter at a time. It's very
durable. We don't see tempomandibular joint problems with
it, or tooth and gum problems. It does the job well without
any side effects for people and it's really popular because
it can fit into just a little box and they can take it with
them if they travel or go places.
Dr. Bob: I think that I would choose to have you pull
my jaw forward rather than stick a mask on my face while I'm
sleeping.
Dr. Barker: And many people do. The more the severity
of the apnea, the more collapsing o the airway, and the more
people need the full support that the C-PAP may give. But
for many people with mild to moderate cases of apnea, this
has been very effective and and a popular way to go.
Dr. Bob: Rosanne Barker, you are amazing. You are
a wonderful teacher and I thank you so much for taking the
time to come to The Dr. Bob Show. This has just been great
information and I can't tell you how much I appreciate your
coming.
Dr. Barker: You are very welcome. Thank you.
Dr. Bob: We took extra time and I've just got a couple
of minutes and we will be talking about some medical problems
that I think are important to your health. What a great show!
