Jessie Gold saw some of the first signs of
0:37
her depression back when she was in college.
0:41
We kind of put the bar at, well,
0:43
I'm getting good grades, so I'm fine. I'm still
0:45
seeing friends, so I'm fine. And I was very
0:47
much that kind
0:49
of person for a long time, so
0:52
really I kind of blew it off
0:54
until I couldn't anymore. And some friends
0:56
and some family members were like, you need to go talk
0:58
to someone about this. And I saw
1:01
a therapist for the first time in
1:03
college my junior year.
1:06
Ultimately, Jessie was able to get help, but
1:08
says the experience of finding treatment
1:10
simply wasn't easy. And that's what
1:13
motivated her to become a psychiatrist, an
1:15
assistant professor at Washington University in
1:17
St. Louis.
1:18
I want to be a safe
1:20
space for people to get help where they don't feel
1:23
like that experience. A lot of
1:25
people are asking for help for the first time in college, and
1:27
I don't want them to be scared to do
1:29
it. I don't want them to have an experience
1:31
where they don't understand what's going on, and I don't want them
1:33
to feel like for some reason they did
1:36
it wrong.
1:36
Today, she's in
1:38
her mid-30s, and Jessie is busy
1:40
helping her students and her patients with
1:43
some of the same struggles she experienced in her
1:45
own life. And she's been really open about the
1:47
journey. But during the pandemic,
1:49
something happened. Dr. Gold says
1:51
she started to do some reflecting and realize
1:54
there's one part of her therapy journey she's
1:57
never been as open about.
1:59
medication for years at
2:01
this point, no changes, say meds, they
2:03
work for me. I haven't really had an episode
2:06
of depression in years. I don't understand
2:08
why I'm hiding that
2:10
in some capacity.
2:12
Now what Jessie did next was honestly
2:14
a little bit meta because she took the
2:16
anxieties about being treated for
2:18
anxiety
2:19
to her own therapist.
2:21
So I talked to my therapist about it for a while and
2:23
she was kind of like, what does medication mean to you?
2:25
And I was like, well I give medicine to everybody
2:27
all the time. It's the same as taking medicine for blood
2:30
pressure. What do you mean by what does medicine mean to
2:32
me? And she was like, no but for you not
2:34
for other people. When I thought
2:36
about it deep down what I thought was
2:38
like if I'm on medicine and people
2:40
know I'm on medicine that will mean to them at some
2:43
point I was sicker or at some point
2:45
maybe I'm not as good of a doctor as I should
2:47
be. My therapist actually told
2:49
me she took medication too and said,
2:51
did that make you think any differently about
2:53
me?
2:54
And I said absolutely not. And she
2:56
was like, see it doesn't make you any
2:59
worse at your job or it doesn't make you change
3:01
your mind about someone you already think is a good doctor
3:03
or professional.
3:05
Here's the reason I wanted to start with this today. I think
3:08
Jessie's story is relatable for a lot
3:10
of reasons.
3:11
We've come so far when it comes to talking
3:13
about mental health but let's
3:15
be honest here there's still a lot of stigma out
3:17
there. After all even a psychiatrist
3:20
like Jessie was reluctant to talk
3:22
about her medications. And at the same
3:24
time now rates of depression are
3:26
rising. You can see where I'm going with this.
3:29
Nearly one in five Americans has been diagnosed
3:31
with depression at some point in their lives.
3:34
And now according to most recent CDC health
3:36
statistics more than one in eight Americans
3:39
report taking an antidepressant drug.
3:42
But the story I'm telling you today is even more
3:44
complicated than that. Because while antidepressants
3:47
can be lifesavers for some people the
3:50
other truth is they don't work so
3:52
well for others if they work at all.
3:55
And for me as a brain scientist
3:57
it raises a fundamental question. What
4:00
exactly is going on in our brains when
4:02
we are depressed? And along
4:05
those lines, why do certain treatments
4:07
like antidepressants help some people like Jesse
4:10
but not as much with others? And
4:13
then there's a lot of discussion about new treatments
4:15
on the horizon, psychedelics, for example.
4:18
So today we're going to explore all of this,
4:21
the inner workings of the depressed
4:23
brain. I'm Dr. Sanjay Gupta,
4:26
CNN's chief medical correspondent. This
4:29
is Chasing Life. You
4:34
know, as we started to research this episode,
4:36
one thing really became clear to all of us. There's
4:39
a lot we don't know about depression.
4:42
Despite how common it is, we still don't
4:44
know exactly what causes it, and
4:46
we don't know how treatments, including
4:49
antidepressants, actually
4:51
work. And there's also a lot
4:53
of debate, controversy, sometimes
4:55
even misinformation, when we do talk
4:58
about the best way to treat depression. So
5:00
when it came to this topic, I knew I wanted to
5:02
turn to someone I could trust.
5:04
I'm Charles Raison. I'm a doctor. I'm
5:07
a psychiatrist. I carry a title
5:09
of professor of human ecology and
5:11
psychiatry at the University of Wisconsin,
5:14
Madison. But I do some other interesting things. I am
5:17
the director of clinical translational research
5:19
for an entity called USONA Institute,
5:21
which is a nonprofit medical
5:23
research organization that's developing psilocybin
5:26
as potential treatment for depression.
5:30
Charles and I go way back. He used to be
5:32
a mental health contributor at CNN. He's
5:35
a really trusted voice in this field for
5:37
me and for so many others. And
5:40
I'll tell you this personally, I would
5:42
sometimes call Charles after covering a
5:44
particularly tough assignment, being in
5:46
a war zone, covering a natural disaster.
5:49
Those were tough times. And sometimes I'd ask his
5:51
advice in terms of how to care for my own
5:53
mental health. So I decided I wanted
5:55
to share some of his wisdom with all of you. I
5:58
wanted to turn to him to talk about the best. these topics.
6:00
And right off the bat, Charles said something
6:03
that really surprised me, that the very
6:05
origins of depression could actually
6:07
go back to our evolutionary drive to
6:09
survive. Depression could
6:12
serve a purpose.
6:13
I actually think depression evolved as
6:15
a way of helping us cope with adversity, even
6:17
though it's very painful. I don't endorse
6:20
depression as a good thing, but that doesn't mean
6:22
that it's not always unhelpful. So, you
6:24
know, a lot of the work that we did at Emory back
6:26
in the days when you and I were working
6:28
together was looking at inflammation and depression.
6:31
And there's some really pretty interesting evidence
6:34
that depression caused by
6:36
inflammation across evolutionary time might
6:38
have helped humans survive infection, right?
6:40
And there's some interesting data that, at least
6:43
in certain contexts, depression
6:45
may actually help people sort of recalibrate
6:47
how they're dealing with their lives, how they're dealing with
6:50
other people, and begin to sort
6:52
of take more productive pathways.
6:55
But if we think about it, that's
6:57
thinking about it sort of like an adaptation.
6:59
One of the interesting questions is, why
7:01
is depression so common if it's so maladaptive?
7:04
And I think the answer is that,
7:07
like a lot of adaptations, like the
7:09
immune system, it can overshoot.
7:13
And when it overshoots, it can really cause problems.
7:16
And then I think a lot of things may cause us
7:18
depression now in the modern world that
7:20
we just didn't evolve to cope with.
7:23
So how does someone know then
7:25
that they should try
7:27
and make a visit with someone like you?
7:30
If you're feeling, you know, unremittingly
7:33
down, if you've lost interest in life, if you're
7:35
asleep and your appetite are altered,
7:37
if you feel hopeless, if you are having
7:39
thoughts of hurting yourself, these sorts of things, that's
7:42
what depression is, right? And people have different combinations
7:44
of them, but that's what it is. You
7:47
need to come see somebody like me when those symptoms
7:49
are interfering with your life. That's, I
7:52
think, the simple answer, right? And especially
7:54
you need to come and see me if those symptoms
7:56
have been going on for a while. You know, if something
7:58
bad happens, you know, it's not a bad thing. happens in your life and
8:01
you have those symptoms for a couple of few weeks,
8:04
I think people like me now increasingly think, you
8:06
know, let's watch and see if it resolves
8:08
rather than immediately pull out a pill. But
8:11
you know, if you say, oh, I've been like this for two or three
8:13
months, yeah, it's time to go see a doctor or
8:15
to go see a clinician and get help. Dr. Justin Marchegiani
8:17
One of the things that we're really focused on in the podcast
8:19
is trying to understand what is happening
8:21
in the brain during various conditions
8:24
of life. If you were to do a
8:26
scan of the brain and you pick the scan, a PET
8:28
scan or MRI scan, functional
8:31
MRI scan, and someone who is depressed,
8:34
could you see depression? Dr.
8:36
Justin Marchegiani With an MRI scan, no. Just looking at
8:38
the brain, no, no, you just the structure of the brain
8:40
would not tell you that. But if you looked
8:42
at the function of the brain with a fMRI,
8:44
let's say, could I put
8:46
you in it, look at it and say, oh my God,
8:48
Sanjay, you're depressed. No, no,
8:51
I couldn't do that. If you give me 40
8:54
people who are depressed and 40
8:56
people who are not depressed and
8:59
I do certain things in the scanner,
9:01
on average, the depressed people's brains
9:04
look different to some degree. But
9:06
that doesn't always pan out across studies
9:08
also. For instance, if you give me a group
9:11
of depressed people, there are several studies that
9:13
have shown that if I put the depressed
9:15
folks in the scanner and I show them
9:17
pictures of faces, their
9:20
brain is less likely to notice happy
9:22
faces and more likely to
9:24
notice scary, angry, sad faces
9:26
and they get more of an activation in
9:29
an area called the amygdala down deep in the
9:31
brain as you know, which is activated by
9:33
danger and threat. And there are
9:35
some, there's some older work by a woman named Yvette
9:37
Shilleen showing that if you treat people
9:39
with an antidepressant, their brains, that
9:42
overshoot of the amygdala calms
9:44
down and they start looking more like folks that aren't depressed.
9:47
So this is it though, right? There's nothing that's anywhere
9:49
near like a brain test for depression.
9:53
Is that a goal? I mean, or
9:56
is that a lark to try and say
9:58
one day we... could
10:01
objectively measure depression
10:03
or is the very nature of what we're talking about something
10:05
that is immeasurable?
10:07
Dr. Seheult Well, sort of interesting. Again,
10:10
it depends what kind of thing depression
10:12
turns out to be. One
10:15
possibility is that it'd be a little bit like trying
10:17
to measure something like dropsy. Remember dropsy
10:20
was this disease back in the 19th century, water
10:22
on the lungs. But water
10:24
on the lungs turns out to be, could be your heart failure,
10:26
it could be pneumonia, it could be cancer. There's
10:29
different reasons to produce those symptoms, right?
10:31
So will we ever find a test for
10:34
diagnosing depression? No, because
10:36
depression is like dropsy. It's
10:38
a cloud, it's a probabilistic
10:40
cloud. It's not a specific sort
10:42
of mechanistic neurobiological
10:45
disorder. The problem is it has to
10:47
do with get fancy, kind of the ontological
10:49
status of depression. Depression is
10:51
not a single thing that's going to yield
10:53
itself to a single test. So we
10:56
got to either break depression down into its component
10:58
parts if we could ever do that, or
11:00
we need to think differently about depression.
11:02
Dr. Seheult You
11:03
know, one of the things that I think really
11:05
sort of inspires a conversation like this is that
11:07
it is seemingly so common.
11:10
I mean, nearly one in five adults diagnosed
11:12
with depression at some point in their lives, that
11:15
number seems to be rising. First
11:17
of all, just broadly speaking, would
11:19
you characterize the state of mental
11:21
health in the United States right now?
11:24
Dr. Seheult Yeah, so you've
11:26
been asking me all these questions. I've kind of
11:28
been equivocating this is an easy one. It's
11:30
bad. It's bad. Oh, you know, I mean,
11:33
there is just no doubt that depression
11:36
and anxiety and suicide and substance
11:38
abuse have been on the rise in the United States. They've
11:41
been on the rise in the United States for probably 20, 25 years,
11:44
maybe longer, but they've really been on the rise
11:46
over the last 10 years. And the data
11:48
are really consistent, you know, the rise is not
11:51
equal amongst all age groups, the
11:53
people that are really suffering are young
11:55
people. So people between the ages of
11:57
like 15 and 35, that's where you see the really,
12:00
really disturbing increase.
12:03
So something's going on in America
12:06
that is really counterproductive
12:08
to the emotional well-being, especially
12:11
of young people. Not every country in the world is
12:13
seeing this, but it's pretty common in industrialized
12:16
societies that whatever we're
12:18
doing in this sort of zeitgeist
12:20
that we're in right now may be good for
12:22
productivity, but it's not good for our emotional
12:25
well-being.
12:26
There is always this this question, are
12:28
we more aware and able
12:31
to identify depression, or
12:34
is it true that the numbers are really going up?
12:37
It's a good point, it's a complex question. They're
12:40
going up, meaning that if you ask Americans
12:42
the same questionnaire, the
12:45
scores are rising. Now, does
12:47
that mean that they're actually feeling more miserable,
12:49
or does it mean that they're aware that they're feeling more miserable?
12:52
But I think most of us think that people
12:54
really are, in fact, more anxious
12:56
and more depressed. And so yeah, you know,
12:59
again, you see this just the same
13:01
scales, these large-scale sort
13:03
of surveys of American populace, and
13:06
you know, the numbers are kind of creeping up. So
13:08
yeah, I'm one of these people who thinks it's a real
13:10
effect.
13:11
One thing, though, that's clear is
13:14
that parallel to that rates of the use of
13:16
antidepressants in the United States
13:18
have skyrocketed
13:20
over the last 20 years, rate in line
13:23
with the increase in rates of depression and suicide.
13:26
So, you know, at the very least, it
13:29
suggests that something's
13:31
not working right, you know, it's a thorny
13:33
and frightening problem. That seems
13:35
to be a big topic of discussion
13:38
lately that, as you mentioned in
13:40
the United States, rates of depression, suicidal
13:44
behavior, anxiety have
13:46
all gone up. Interestingly,
13:49
even before the pandemic, life expectancy in
13:51
the United States had gone down, and one of
13:53
the top drivers of premature death was suicide.
13:56
At the same time, we're taking more drugs, including
13:59
antidepressants, than ever before. So
14:02
despite the fact that we have higher rates
14:04
of depression, we take more medications, the numbers
14:06
just keep getting worse. If someone
14:08
were to sort of piece that together, you know, visit
14:10
from another planet and say, hey, what's going on here?
14:12
That would not make sense.
14:15
Yes. So this is the question
14:18
of the use of antidepressants, which are
14:20
the first line treatment for depression in the United States
14:23
is incredibly complex. I always, whenever
14:25
I start with this, I always start by saying,
14:27
you know, anybody that's worked as a psychiatrist
14:29
or in mental health knows that these agents, you know,
14:31
standard antidepressants are have, man,
14:33
they are lifesavers for some folks. But,
14:37
but as we've gone along in
14:39
the last 20 years, we've had to metabolize
14:42
as a field, a number of very
14:44
hard truths about antidepressants
14:47
and their effectiveness. One hard truth
14:49
and the most obvious one is that they
14:51
don't work nearly as well as we thought they did 30
14:54
years ago. And in fact, they probably
14:56
if I give me a whole group of depressed people,
14:59
and let me start an antidepressant and
15:01
have them take it every day, probably 30%
15:04
max are going to get a full response
15:07
and probably another 20% 25% are
15:09
going to feel better. And there's gonna be a
15:11
bunch of people that really don't get much benefit. Now that's
15:13
a huge problem. And studies we
15:16
now know from studies that you know, see, didn't first
15:18
one didn't work. So we're gonna try a second one. Okay,
15:21
but by the time you're doing third and fourth, your chances
15:23
of responding go down, down, down, right? So it's
15:26
like there's a group of people that are antidepressant
15:28
responsive. And then there's a lot of people
15:30
that aren't really very antidepressant responsive.
15:33
And that's a problem. And you know,
15:35
there, there is some evidence not
15:37
much talked about that at
15:40
least sometimes antidepressants might
15:42
set you up for having more depression if
15:44
you decide to stop them. And
15:46
that is something to worry about. And,
15:49
you know, I talk about this often just
15:51
because the data are
15:53
not conclusive, but they're, they're concerning,
15:56
right? It really highlights the fact that you
15:58
know, it's a good thing we have treatments.
15:59
But man, we need to keep looking for new treatments
16:02
for these things because there's a lot of room for improvement.
16:05
Is depression a chemical
16:08
imbalance? Not
16:10
the way that it's meant colloquially,
16:13
meaning that, you know, I can't, you know, look
16:15
into your brain and like a dipstick and measure your
16:17
serotonin or your norepinephrine. No,
16:19
in fact, the vast majority of people with depression don't
16:22
have, you know, obvious measurable
16:25
abnormalities in any brain chemicals. Nowadays,
16:28
I think many of us think that if there is a brain
16:30
thing that we can understand, it probably has to do more with
16:33
how the brain areas talk to each other. So,
16:35
no, you know, I think that it's becoming
16:37
increasingly clear that these older
16:39
simple ideas of chemical imbalance,
16:42
they don't fit the data very well. Yeah,
16:44
it's a nice narrative, right? I think,
16:46
again, and we like narratives. We like
16:48
to hear that your cholesterol is too high and
16:50
that's going to cause you to have heart disease. Your
16:53
serotonin is too low. So, we'll give you an
16:55
SSRI, a selective serotonin
16:57
reuptake inhibitor, just to keep your
17:00
serotonin around longer and that should help.
17:03
But it's interesting.
17:05
You know, on one hand, I was reading an article
17:07
that said you can give aspirin
17:09
for pain and that should help
17:12
your pain, but that doesn't mean you're, quote unquote,
17:14
aspirin deficient. You
17:16
can give serotonin or you can create
17:18
more serotonin for your brain. Doesn't necessarily mean
17:20
you're serotonin deficient, even if that serotonin
17:23
does help alleviate your symptoms
17:25
of depression. And I know that sounds
17:27
like maybe talking in circles, but I think it makes the
17:30
point that you're making, which is it's very hard
17:32
to call this a chemical imbalance. Even if
17:34
a selective serotonin reuptake
17:36
inhibitor, SSRI, works, it doesn't
17:39
necessarily mean that there was a chemical imbalance.
17:42
It meant that getting more serotonin actually
17:44
just made you feel better. That's right. But
17:46
there's an implication of that, which is that,
17:49
yeah, antidepressants are not doing something
17:51
natural. So they're not, you know, it's not
17:53
that your serotonin is low. So we're just going to fill
17:55
your tank. It's that if you give people
17:58
an agent that sort of pushes. serotonin
18:00
signaling in the brain for some
18:02
group of depressed people, it makes them feel better.
18:05
But that antidepressant is pushing on the brain to
18:07
make them have that benefit, which
18:10
again is why when people take away the antidepressant
18:13
rates of relapse are probably so high because
18:15
the brain was needing that
18:17
sort of push of the medication.
18:20
The medication was not restoring some sort
18:22
of pre-existing balance that
18:25
was lost. It's doing something novel
18:28
to make the person feel better.
18:31
Look it's all still pretty mysterious
18:33
in reality, but I've got to say I
18:35
do like the way Charles approaches all
18:37
of this. It's important to acknowledge
18:39
that for some people like Jesse who you heard from
18:42
earlier, antidepressants
18:44
not only work, but they're a lifeline. But
18:46
at the same time there is data to show it's
18:49
definitely not a one size fits all treatment
18:51
and we're not even entirely sure why
18:54
or how they even work. That's
18:56
why after the break Dr. Rizan and I are going to talk about
18:59
other options, newer options on the horizon,
19:02
including psychedelics. They
19:04
are probably the most interesting development
19:06
in the treatment of mood and anxiety and
19:08
post traumatic stress disorder, probably alcohol
19:11
and drug abuse that I've seen in the 40
19:13
years that 30, 40 years that I've been a psychiatrist.
19:16
That's a significant statement coming
19:18
from you. Oh yeah. Oh yeah. That's
19:21
quite remarkable. We're going
19:23
to talk about the future of depression treatment in just
19:25
a moment. But you know, before we go, a reminder,
19:28
if you or someone you love is struggling,
19:31
there's help available for you right
19:33
now. You can call the national suicide
19:36
and crisis lifeline anytime 988.
19:47
We're less than a year out from a presidential
19:49
election in the US. I realized
19:52
that may kind of stress you out, but CNN
19:54
five things is here to help. We're
19:56
a podcast that gets you caught up on five
19:58
big stories in five minutes. whether
20:01
it's keeping up with politics or anything else
20:03
that's going on in the world, we've got you covered.
20:06
That's the CNN Five Things Podcast. Listen.
20:09
On your favorite podcast.
20:21
One of the things that's come up quite a bit is
20:23
psychedelics, and this is an area of interest of
20:26
yours as well. You know, I've got
20:28
to say it's pretty compelling, and I'm
20:30
pretty conservative
20:32
on these things, even on cannabis. It took
20:34
me a while to sort of fully appreciate, which
20:37
I do now, the medical benefits
20:39
that cannabis can offer for certain things. What
20:42
about psychedelics? You're a well-regarded,
20:45
well-known psychiatrist in
20:47
this country. I listen to you. You're the guy
20:49
I go to. What do you think
20:51
about psychedelics and depression? You've
20:54
come to the right place, actually, because
20:57
this is what I spend much of my life doing these
20:59
days, is trying to understand, do
21:01
psychedelics work? What do they work for? And
21:03
then how do they work? And so one
21:06
of the hats I wear is directing research
21:08
for a kind of very novel medical
21:11
research organization called Usona Institute,
21:14
which is one of the entities in the world that's working
21:16
to get FDA approval for psilocybin,
21:18
which is a psychedelic, as a treatment
21:20
for major depression. This
21:23
is mushrooms? It's the psychedelic substance
21:25
in mushrooms. We produce the psilocybin,
21:27
as do other commercial entities. We produce
21:29
it. So it's a synthesized substance,
21:32
but it's based on what's in mushrooms? Exactly.
21:34
It's the same thing. We just did this 104-person study with
21:37
people who are really depressed,
21:41
gave them a single high dose of psilocybin with
21:43
psychosocial support. Huge improvement
21:46
in their depression. One
21:48
dose, and the study lasted for six weeks.
21:50
At the end of six weeks,
21:51
a lot
21:55
of the folks that were really depressed were significantly
21:58
better with psilocybin.
21:59
been showing over and over again, you know.
22:02
There are now just a handful, you know,
22:05
growing handful of studies, some of them like ours,
22:07
fairly large, showing that a single
22:10
high dose of psilocybin produces a
22:12
very rapid, very, very robust
22:15
and sustainable antidepressant effect. So
22:18
yeah, I mean, I think, you know, of, of
22:20
I'm one of these people that thinks that although these agents
22:22
are going to have their challenges, of which there are many, and
22:25
they're going to have their risks, they are probably
22:27
the most interesting development in the treatment of
22:29
mood and anxiety and post-traumatic stress
22:31
disorder and probably alcohol and drug
22:33
abuse that I've seen in the 40 years, the 30,
22:36
40 years that I've been
22:38
a psychiatrist. That's, that's a significant statement
22:41
coming from you.
22:42
Oh yeah. Oh yeah. No, it's quite
22:44
remarkable.
22:45
What do psychedelics do in the brain
22:48
that causes such a benefit
22:50
when it comes to depression? Yeah, we don't
22:53
fully know. But you know, it's interesting,
22:55
the most consistently observed predictor
22:58
of response is not
23:00
at this point, a brain measure, it's actually
23:02
a behavioral measure. So you know, psychedelics
23:05
are very different, you know, let's Prozac, Paxil,
23:07
whatever the SSRIs, you know, you're depressed,
23:09
you start taking them, and maybe you feel
23:11
a little bit weird because they have side effects. And if they
23:13
work, you know, you feel better in a couple of weeks, but you
23:15
don't know why you feel better. It's not like
23:17
you had a eureka aha moment. Psychedelics
23:20
is totally different though, you know, so in
23:22
our studies, when you come in, I give you a 25
23:24
milligram dose of psilocybin, almost
23:27
everybody is now going to have a very
23:29
intense psychedelic experience. And
23:31
those experiences tend not
23:34
to be random, they tend to have characteristics
23:36
that if those characteristics occur, people
23:39
are going to be undepressed afterwards. And so
23:41
for instance, one of the things that psychedelics
23:44
tend to do is they induce these things called mystical
23:46
experiences, which are really these
23:48
states where people feel much more
23:50
deeply connected than they had previously to
23:53
other things, to the universe, to God, to other
23:55
people, they have this feeling that their lives
23:58
are meaningful in ways that they didn't realize.
23:59
before and just sort of fills them often with
24:02
the sense of joy. They're like, wow, I
24:04
am meaningfully part of something larger
24:07
that matters, that's going someplace good.
24:10
When that happens, during the psychedelic
24:12
experience after you take the drug, the
24:14
more that happens, the more likely you are to
24:16
be undepressed six weeks later, six
24:19
months later. And then the other thing
24:21
that psychedelics do is quite interesting is that
24:23
they tend to bring people face-to-face with
24:25
the issues that they're dealing with. So one of
24:27
the things we know about depression is when you're
24:29
depressed,
24:29
you tend to avoid things that are very painful
24:32
and you get depressed because you avoid things
24:34
that are very painful. Psychedelics interrupt
24:36
that process, you know. So if you're struggling,
24:39
if you're depressed because you're feeling bad about yourself
24:41
because of something, psychedelics
24:44
will very often
24:45
put that something right in front of your face.
24:47
And this can be very, very difficult for people.
24:50
And so many people in our studies
24:52
that have depression will really have
24:54
a rough go during the psychedelic experience. They'll
24:56
cry, they, it's
24:59
just emotionally very powerful.
25:02
There's no escape, you know. It's not like I could say,
25:04
oh, I'm just going to forget about it. If
25:06
that happens to you
25:08
and if you deal with it, if
25:10
you face the problem, if you feel like you've either
25:13
faced it in a way that's going to let you make a change
25:16
or faced it in a way that's going to let you accept something
25:18
that you cannot change, in the field
25:20
it's called an emotional breakthrough. And if
25:22
that happens, people are also much
25:24
less likely to be depressed and anxious, like
25:27
weeks and weeks later. So that's
25:29
the thing we know about these agents at this
25:31
point is that it seems like there's something,
25:34
it's more like psychotherapy in that
25:36
regard, right? And this is where sometimes people say
25:38
it's like a year of psychotherapy in a day. You
25:40
just, it recalibrates how you
25:43
see your life.
25:44
This eureka moment Dr. Raisan is
25:46
describing highlights, I think, a key
25:48
difference in the way traditional SSRIs work
25:51
versus psychedelics in terms of treating
25:54
depression. Compared to SSRIs,
25:57
psychedelics are going to work much faster
25:59
and And they're going to appear to have longer
26:01
lasting effects. That's because they
26:03
seem to ignite this explosive
26:06
neuroplastic response. Your
26:08
brain just starts to light up all over the place.
26:11
And it causes the brain to create these entirely
26:13
new pathways or at least unobstruct
26:16
existing pathways making these
26:18
connections between parts of the brain that
26:21
normally don't communicate much. For
26:24
example, he said the feelings we keep
26:26
buried away in the emotional centers of the brain,
26:29
they kind of suddenly pop
26:31
into conscious awareness. Think about that.
26:34
You keep these things buried away. You
26:36
take this psychedelic according to Dr. Raison
26:39
and all of a sudden those things that were
26:42
inhibited, that were buried pop
26:44
into our conscious awareness. Another
26:46
key difference Dr. Raison said is that unlike
26:49
an antidepressant pill that you have to take every
26:51
day, psychedelics appear.
26:54
And I want to be careful here because this is still new
26:56
science, but psychedelics appear to
26:58
set something in motion in our brains that
27:01
somehow stays in motion. It becomes
27:03
self-sustaining so you don't have
27:05
to take them frequently, certainly not every day.
27:08
Charles referred to SSRIs,
27:10
again the selective serotonin reuptake
27:13
inhibitors, these antidepressants. He
27:15
referred to them as a gas grill that
27:17
will go out if you don't keep giving
27:19
it gas. Psychedelics
27:21
he said are more like a campfire. Once
27:24
you light it, it burns for a while.
27:26
Now look, again, these findings are promising,
27:29
but there's still a lot we don't know about how
27:31
psychedelics treat depression, just like we don't
27:34
know how antidepressants really work. There's
27:36
also the question that a lot of you are probably immediately
27:39
asking about the federal regulations.
27:43
So you know, we and everybody else in the space
27:46
working to get FDA approval is synthesizing
27:48
these agents to this insane
27:51
purity that you have to do for the Food and Drug Administration.
27:54
And we're doing the kind of studies that if they're positive,
27:57
traditionally cause the FDA to say, okay, I'm
27:59
going to do this. we're going to give you approval to
28:02
use this medicine. I
28:04
think it's very clear that because psychedelics
28:06
induce these very powerful, acute,
28:09
you know, psychedelic what are colloquially called
28:11
trips, they're never going to be agents
28:13
that you take it home on a Saturday morning, right? Almost
28:16
certainly they will be administered in a
28:19
clinical setting where there's safety. They
28:21
will be administered with people that are in
28:23
the room with you in case you really
28:25
start struggling. So these are, but
28:28
these are hurdles. You know, there's some real challenges
28:29
there.
28:32
I remember back when I was a medical student, there
28:34
was some papers that were actually written about hypothermia
28:38
and actually patients who are in acute crisis,
28:40
mental health crisis to actually
28:43
use hypothermia. What you've
28:45
written about is the effectiveness of heat therapy.
28:48
Is this something that can work? Oh, yes. Hyperthermia.
28:51
Yes. Yes. Yes.
28:54
Oh, yes. trying
28:57
to retread ancient
28:59
practices, you know, psychedelics. We're talking
29:01
about psychedelics. They've been around for thousands of years. Heat,
29:04
you know, heat has been a healing modality in almost
29:06
every culture for millennia,
29:08
you know, all of Native Americans and all
29:11
sweat lodges and the baths in Asia and, you know,
29:14
so we've known for a long time that heat has
29:16
beneficial properties.
29:19
Cold though probably does too. I've
29:22
got a colleague out in Colorado, Christopher Lowry,
29:24
who's shown that in animal models, cold
29:27
and heat have very similar signaling capacities
29:29
on the brain. And now some
29:31
of my colleagues have done studies showing that if
29:33
you're depressed, that I can put you
29:36
in a machine of one sort or other that will
29:38
elevate your body temperature. We like to get people
29:40
up to about 101.3 Fahrenheit, which is 38.5 centigrade. It's
29:44
hot. If you're pouring sweat,
29:46
it's really hot. But if I do that, if
29:50
I do that in a group of depressed people, very reliably,
29:52
their depression scores drop by about half.
29:56
Some people get much better than that, right? And
29:58
the biggest study that we've done is that we've done it in one group. done, we gave
30:00
people a single treatment, their scores dropped
30:03
considerably and they stayed improved
30:06
for six weeks. So this is another
30:08
one of these sort of more ancient ways of doing
30:10
things that I think can be
30:13
kind of spruced up and be another sort
30:15
of option for folks. But
30:18
people now, of course, they asked me about it because this is, we've
30:20
really shown there seems to be something here.
30:23
And what I tell people is, if you go to the sauna
30:26
and you feel better, if you
30:28
can stand doing it by yourself,
30:31
just a regular old rectal thermometer, put
30:33
yourself in the heat and monitor your
30:35
body temperature a couple of times, see
30:37
what it feels like to get up to about 101.3 and then try to
30:39
do it. Because
30:43
we know, we look at people in
30:45
our studies very carefully and there's a dose
30:48
response relationship. You do get
30:50
more of an antidepressant response at higher temperatures,
30:52
right? So it really is worth, frankly,
30:55
it's worth doing. I do this all the time.
30:57
I do. Oh yeah. I'm
30:59
in a
30:59
clean shower and I use it every day.
31:02
For me, it's really, it's
31:06
huge.
31:07
When you listen to Charles, another psychiatrist,
31:09
talking about the new treatments on the horizon
31:11
for depression, you can't
31:14
help but realize that what was old can
31:16
be new again. We're talking about plants.
31:19
We're talking about heat. We're talking about
31:21
ancient traditions. And in some ways,
31:23
I think that should make you feel a little
31:26
bit more hopeful. Don't get me wrong.
31:28
The statistics, the rising rates of depression
31:30
that we talked about, that is real. That
31:33
is something we have to pay attention to. And
31:35
right now, it feels like the world around
31:38
us is pretty inflamed. But
31:40
at the same time, as Charles points out,
31:43
at this point in history, there
31:45
are more treatments for depression than
31:47
ever before. And there are many more
31:50
promising treatments on the way.
31:52
But what I like about psychedelics and what I
31:54
like about hypothermia is they share something in common
31:56
that I think is a potential path forward
31:59
as we think about... novel treatments for depression,
32:01
which is this. Unlike
32:03
a pill that you take every day that the brain then accommodates
32:06
to and begins to kind of push against.
32:10
Psychedelics and hypothermia, but especially psychedelics
32:13
seem to set, they're drugs, they're very
32:15
powerful drugs. They come from
32:17
the outside, they set something in motion, but
32:20
then they're gone. And whatever they've set in
32:22
motion stays in motion and it becomes
32:25
something that becomes a sort of self-sustaining
32:27
within the mind, body, brain complex.
32:30
It requires oxygen and things from
32:32
the environment like everything does, but it has
32:34
a self-sustaining life of its own. Psychedelics
32:38
like the match, they seem to light something and
32:40
then the fire burns for a while. And
32:43
I think that metaphor is one that
32:45
we should take more seriously in terms of
32:47
trying to identify new treatments.
32:49
That makes a lot of sense. Oh, that'll stick with me for
32:51
sure. Let me just ask
32:54
you in closing, I'm
32:57
very diligent about exercise. I
32:59
know exercise can help new brain
33:01
connections, more BDNF,
33:04
it's called, brain-derived neurotrophic factor. I
33:07
meditate every day now. I know that
33:09
can help with feelings of stress and anxiety. I'm
33:12
really diligent about sleep. As busy
33:14
as you and I both are, my guess is you're
33:16
diligent about sleep as well. She
33:18
told me just now you also do steam showers
33:21
to try and raise your body temperature. But
33:23
I have a terrible history of family history
33:25
of heart disease. So I do all these things
33:28
to ward that off. To
33:31
prevent mental illness, mental
33:33
health problems later in life, what
33:36
should I be doing? What do you do? Well,
33:38
all the above. So everything you said is those
33:41
are all fantastic things, right? So if
33:43
I had a short list, you've just named a bunch of
33:45
the short list. The thing that I
33:47
do in addition to that, that I found
33:49
very, very helpful, is
33:51
to work on developing
33:55
an attitude of
33:59
thankfulness. for the fact that I
34:01
exist. Thankfulness for
34:04
the people in my life. This sort of trying
34:07
to foster a sort of, I'm looking out the window, it's
34:09
a beautiful autumn day up here in Wisconsin,
34:11
trying to foster this sense
34:13
of wonder that in this crazy amazing
34:16
universe, we're here and we're conscious.
34:18
I had this idea that there's certain mental states
34:21
that make depression impossible. The
34:23
grief is possible in those states, but not
34:25
depression. It's just, it's very hard
34:27
to get to those states. But
34:30
we talk about psychedelics, psychedelics often put people
34:32
in those states, at least briefly. So
34:35
that's the other thing I do, is I really try to foster
34:37
that sense of
34:39
kind of wonder and gratitude. That
34:43
for me helps a lot. That and the steam showers.
34:47
They help me a great deal.
34:52
Steamy showers and gratitude.
34:55
What I like about these two parting pieces
34:57
of advice from Dr. Raison is that
34:59
these are small things anyone can try.
35:02
And just a reminder, of course, that this isn't gonna help
35:04
with all kinds of depression. If you
35:07
or someone you love is seriously struggling,
35:09
there can be help available for you. You
35:11
can call the National Suicide and Crisis Lifeline
35:14
anytime, 988. Also,
35:17
we'd like to hear from you. Give us a call. What
35:20
are some tips that have helped you care for your mental
35:22
health? Give us a call, 470-396-0832. Your
35:27
message could help others, could be featured
35:29
on an upcoming episode of the podcast. Plus
35:32
next week, we're gonna dive into
35:34
the world of dating apps,
35:37
or introducing apps, as
35:39
they are now called. How have they changed
35:41
how we find love? And what
35:44
is all that swiping doing to your
35:46
brain? The answers might surprise
35:48
you. The brain
35:49
is built to love. And
35:52
all these dating sites, introducing
35:54
sites, are built for only one
35:56
thing. Introduce you to people
35:59
so that you can then.
35:59
pick up the ball
36:02
and move it down the road. That's
36:05
next time on Chasing Life. Thanks
36:07
for listening.
