Is MDMA psychiatry’s antibiotic? | Ben Sessa | TEDxUniversityofBristol
-
0:17 - 0:223,4-Methylenedioxymethamphetamine: MDMA.
-
0:22 - 0:27Now you're probably heard of this compound
in the context of the recreational drug Ecstasy. -
0:27 - 0:32But today I want to talk about MDMA not
as a recreational drug, -
0:32 - 0:36but as a potential new treatment in medicine.
-
0:36 - 0:40And then very important treatment
for psychiatry because MDMA could offer us -
0:40 - 0:45in psychiatry for the first time the
opportunity to tackle trauma. -
0:45 - 0:50And psychological trauma particularly that
caused by child abuse and maltreatment -
0:50 - 0:57is at the heart of all or most psychiatric
disorders due to anxiety and addictions. -
0:58 - 1:02Psychiatry is in need of this
innovative approach, -
1:02 - 1:05because current treatments
are failing patients. -
1:06 - 1:10Hi, my name's Ben Sessa. I'm a child and
adolescent psychiatrist. -
1:10 - 1:12Now that means I trained as a medical doctor,
-
1:12 - 1:14then specialized in mental health
-
1:14 - 1:17and then specialized in child
and adolescent mental health. -
1:17 - 1:20But for the last five years I've
been working with adults with -
1:20 - 1:24mental health disorders and addictions
due to misuse of drugs. -
1:24 - 1:28And that developmental pathway
of my own, -
1:28 - 1:30from working with child abuse into adults
-
1:30 - 1:34with mental disorders and addictions has
brought me to the door of MDMA. -
1:35 - 1:37And I'm gonna propose today
that MDMA could be -
1:37 - 1:42important for the future of psychiatry
as the discovery of antibiotics was -
1:42 - 1:44for general medicine a hundred years ago.
-
1:45 - 1:51So when we think about child abuse we think
about physical abuse, mental abuse, -
1:51 - 1:54emotional abuse, sexual abuse and neglect.
-
1:55 - 1:58And we think about noxious environments.
-
1:58 - 2:00About parents with mental disorder.
-
2:00 - 2:02We think about parents
who are addicted to drugs. -
2:02 - 2:07And social issues like poverty and
poor housing, poor education. -
2:07 - 2:10Now I'm going to illustrate my talk
today with a patient -
2:10 - 2:12and I'm going to call her Claire.
-
2:12 - 2:16Now Claire was no single particular
patient of mine. -
2:16 - 2:19Rather she's an amalgamation
of many different people -
2:19 - 2:22I've met in the last 18 years working
as a medical doctor. -
2:23 - 2:25She's certainly not the worst.
-
2:26 - 2:29Now what was Claire's environment like
when she was growing up? -
2:29 - 2:31Well, her mother was depressed.
-
2:31 - 2:35Now unfortunately the family
doctor didn't have time to accurately -
2:35 - 2:38diagnose and treat depression, rather,
-
2:38 - 2:41Claire's mother was put onto one
antidepressant after another, -
2:41 - 2:43never really got therapy.
-
2:43 - 2:45Claire's mother also had a lot
of aches and pains -
2:45 - 2:48typical what we call
psychosomatic symptoms in depression, -
2:48 - 2:53and as a result the family doctor
put her on to opiate based painkillers -
2:53 - 2:56which she promptly became addicted to.
-
2:56 - 2:59Now Claire's father, now he was alcoholic
and he was often -
2:59 - 3:01not around in and out of prison.
-
3:01 - 3:03Which is just as well because when he was
there -
3:03 - 3:06he was physically abusive to Claire
and her mother. -
3:06 - 3:08Okay so what does this kind
-
3:08 - 3:11of chaotic, frightening environment do
-
3:11 - 3:14to the developing child brain?
-
3:14 - 3:17I'm going to give you a brief
neurophysiology lesson if I may. -
3:17 - 3:20There's a part of the brain called the amygdala.
-
3:20 - 3:23Now the amygdala is a very
ancient part of the mammalian brain -
3:23 - 3:27and many other animals other than humans
have an amygdala. -
3:27 - 3:30The amygdala lights up when stimulated by
-
3:30 - 3:33fear in the environment,
by a frightening stimulus. -
3:33 - 3:37It lights up and it says:
fight-or-flight, get out! -
3:37 - 3:40Now there's another part of the brain
much more sophisticated part, -
3:40 - 3:45called the prefrontal cortex and it's
right here at the front above the eyes. -
3:45 - 3:47Now the prefrontal cortex only humans have.
-
3:47 - 3:52And it's in the prefrontal cortex
where we use logic and reasoning to -
3:52 - 3:55rationalize the situation and we can use
-
3:55 - 3:58our prefrontal cortex to overcome that
-
3:58 - 4:01instinctive fear response from the amygdala.
-
4:01 - 4:03Now when Claire was growing up
-
4:03 - 4:05she never knew from one moment to the next
-
4:05 - 4:08whether the adult coming into the room's
going to give her a kiss -
4:08 - 4:10or a cuddle or do a jigsaw with her,
-
4:10 - 4:12or were they going to punch her or kick her
-
4:12 - 4:14or burn her with their cigarette.
-
4:14 - 4:17Or were they going to rape her.
-
4:17 - 4:20Because throughout her childhood
Claire was also subjected to sexual abuse. -
4:22 - 4:26Now, there's a group of disorders
called the anxiety disorders, -
4:26 - 4:32and one of the most important is what we
call post-traumatic stress disorder or PTSD. -
4:32 - 4:35Now PTSD, some of the core features:
-
4:35 - 4:39very low mood, anxiety,
high levels of anxiety, -
4:39 - 4:41what we call hyper vigilance:
-
4:41 - 4:43this edginess, this jumpiness.
-
4:43 - 4:47Exactly how Claire felt
throughout her childhood and adolescence. -
4:47 - 4:50Never knowing whether
the next assailant or assault -
4:50 - 4:52was around the corner.
-
4:52 - 4:56Another core feature of PTSD,
what we call re-experiencing phenomena. -
4:56 - 5:02Flashbacks, when the patient has sudden
remembrances of painful traumatic memories. -
5:02 - 5:03They can just pop into the head
-
5:03 - 5:07at any time, triggered by
some cue in the environment. -
5:07 - 5:11And when they have those experiences,
those daytime flashbacks, -
5:11 - 5:15they relive the trauma in all the
sensory modalities and this results in -
5:15 - 5:19them freezing or dissociating
to try and block out the pain. -
5:20 - 5:23Claire experienced all of this
as she was growing up. -
5:24 - 5:29High levels of self-harm and suicide
are associated with PTSD. -
5:29 - 5:32Claire would cut her thighs and her breasts.
-
5:33 - 5:37Pretty common form of cutting in
children who've been sexually abused. -
5:37 - 5:40She was being sexually abused
by her mother's clients, -
5:40 - 5:44because her mother had moved on
from the addiction to painkillers and -
5:44 - 5:47was using street heroin
when Claire was a teenager. -
5:47 - 5:51Because of the way the war on drugs has
set up that reduces access to treatment -
5:51 - 5:55for people with opiate dependence,
she had to pay for her -
5:55 - 5:59heroin using sex work and the clients
would sexually abuse Claire. -
6:00 - 6:05It's very hard to treat PTSD and
it has a high treatment resistance, -
6:05 - 6:0950% of people do not respond
to the traditional treatments. -
6:10 - 6:11How do we treat it?
-
6:11 - 6:15We can treat it with medications.
We can treat it with psychotherapies. -
6:15 - 6:19And the medications we use:
there's a broad range of drugs. -
6:19 - 6:25No single drug, and this is very important,
no single drug cures PTSD. -
6:25 - 6:27Rather we treat the disorder symptomatically:
-
6:27 - 6:30If the patient's depressed
give them an antidepressant. -
6:30 - 6:34If their mood fluctuates give them a mood stabilizer.
-
6:34 - 6:37If they can't sleep give them a hypnotic.
-
6:37 - 6:41And if that edginess and that fear
spills over into paranoia and psychosis, -
6:41 - 6:44give the patient an anti-psychotic drug.
-
6:44 - 6:48And they have to take these drugs
day in day out for weeks, months, decades. -
6:48 - 6:54They have to keep taking them because
the drugs we use to treat trauma when it's -
6:54 - 6:59due to this level of severity do not
attack the root cause of trauma. -
6:59 - 7:02They paper over the cracks.
-
7:02 - 7:08A good analogy would be taking aspirin
or ibuprofen when you have a fever. -
7:08 - 7:13A fever is caused by an infection,
by a microorganism. -
7:13 - 7:18Sure, you can take paracetamol or ibuprofen
and this will lower the temperature -
7:18 - 7:22and make you feel a bit better
but it doesn't attack the root cause. -
7:22 - 7:27And that's what we do when we give
these patients these daily SSRI drugs. -
7:27 - 7:28We paper over the cracks.
-
7:28 - 7:32We maintain the symptoms
at a manageable level. -
7:32 - 7:36We also use psychotherapies to treat PTSD,
and there's -
7:36 - 7:42again a broad range of these: DBT, CBT,
EMDR, trauma focused psychotherapy, -
7:42 - 7:45CAT, APT... Now all of them have a pretty
-
7:45 - 7:49similar approach which actually is
an old wives tales which is: -
7:49 - 7:51a problem shared is a problem halved.
-
7:51 - 7:56"Let's talk about your trauma.
Claire tell me about your rape." -
7:56 - 8:04Now that's fine for 50% of patients but for
a significant half they just cannot do that. -
8:04 - 8:07As soon as Claire is asked to talk
about her rape she freezes, -
8:07 - 8:10she flees, she drops out of treatment.
-
8:10 - 8:14By the time she was 15 Claire had been
removed from the family home and she was -
8:14 - 8:18brought up in a succession of foster
placements and children's houses and -
8:18 - 8:22hostels where the abuse continued.
-
8:22 - 8:25She was self-harm cutting and
she started drinking and -
8:25 - 8:29by the time she was 18,
she was using heroin as well. -
8:29 - 8:34Sometimes working in psychiatry can feel
pretty desperate, can feel pretty hopeless. -
8:34 - 8:39Sometimes it feels as if psychiatry
is a palliative care profession. -
8:39 - 8:42And this is the truth because
the treatments we use do not get to the -
8:42 - 8:45root cause of the problem, the trauma.
-
8:45 - 8:47They paper over the cracks.
-
8:47 - 8:50And I think the pharma industry know this
and they queue up and they -
8:50 - 8:54provide us with product after product to
give to our patients that doesn't quite -
8:54 - 8:58cure them but it gets them
slightly better to function. -
8:58 - 9:00And they have to keep taking them.
-
9:00 - 9:05I'd say that we're in psychiatry today where
we were in general medicine 100 years ago. -
9:05 - 9:07100 years ago in general medicine,
-
9:07 - 9:10humanity was losing the battle
to the infectious diseases. -
9:10 - 9:13Oh we were very good at classifying
and diagnosing them. -
9:13 - 9:15We knew who got smallpox.
-
9:15 - 9:17We knew people died of post-operative surgery.
-
9:17 - 9:21We knew there were microorganisms
but we didn't have a treatment. -
9:21 - 9:26And then at the beginning of the 20th
century we discovered the antibiotics. -
9:26 - 9:30Not symptomatic treatment but treatment
that goes to the core of the cause -
9:30 - 9:34and we started getting on top
of infectious disease. -
9:34 - 9:37Psychiatry today is in a similar place.
-
9:37 - 9:40We're very good at classifying and diagnosing.
-
9:40 - 9:42Our epidemiology is superb.
-
9:42 - 9:44We write these thick diagnostic manuals.
-
9:44 - 9:46We know who gets depression.
-
9:46 - 9:47We know who gets anxiety.
-
9:47 - 9:54We even know the cause: trauma, child abuse,
maltreatment, poor social conditions. -
9:54 - 9:56But our treatments are lousy.
-
9:58 - 10:01And I'm quite shocked the way the empathy
-
10:01 - 10:05switch and our understanding of these
patients seems to be switched off. -
10:06 - 10:10We have lots of gushing sentimentality for
the little five and six year old who's -
10:10 - 10:15being abused and we throw money at our
television sets on these campaigns to -
10:15 - 10:18improve the lives of these
poor little innocent victims. -
10:18 - 10:21Let me tell you what happens to
that little five or six year old, -
10:21 - 10:23when they're 11 or 12.
-
10:23 - 10:27On goes the hood, start smoking weed.
-
10:27 - 10:29By the time they're 16 they're
buying and selling amphetamine -
10:29 - 10:31and by the time they're Claire's age
in their mid-20s, -
10:31 - 10:34they're addicted to heroin and alcohol.
-
10:34 - 10:37And suddenly we have lost our empathy.
-
10:37 - 10:39These people are public enemy number one.
-
10:39 - 10:45"It's your fault Claire. You brought this
upon yourself. It's your lifestyle choice." -
10:45 - 10:50And I'm quite shocked and having worked in
pediatrics and seen the developmental -
10:50 - 10:55trajectory that is so inevitable from
early trauma into adolescent and then -
10:55 - 11:00adult mental health and addictions, we have
to hold on to that sense of compassion -
11:00 - 11:04and evidence-based understanding
about the developmental trajectory there. -
11:06 - 11:09So it does sound desperate,
but all is not lost. -
11:10 - 11:14MDMA. MDMA has some fascinating qualities.
-
11:14 - 11:19I would suggest that if you were to invent
a hypothetical drug to treat trauma, -
11:19 - 11:22it would be MDMA.
-
11:22 - 11:26The way it works in terms of its receptors
and its subjective psychological effects -
11:26 - 11:28ticks all the right boxes.
-
11:28 - 11:31At one level of receptors it causes
a increased positive mood. -
11:31 - 11:34Lowering of depression, lowering of anxiety.
-
11:34 - 11:37At another group of receptors it speeds
the patient up, -
11:37 - 11:42mild stimulation which motivates them
to engage in therapy. -
11:42 - 11:45At another level it relaxes
the patient paradoxically -
11:45 - 11:50at the same time as the stimulation and this
puts the patient into the optimal arousal -
11:50 - 11:53zone where they can engage in psychotherapy.
-
11:53 - 11:59But perhaps the most important thing about
MDMA and the most important clinical tool -
11:59 - 12:06is its ability to provide a sense of empathy
and understanding and emotional security. -
12:07 - 12:12It can hold the patient in a place where
they can think about and access their trauma -
12:12 - 12:15like they've never been able to do before.
-
12:16 - 12:18One of the ways in which MDMA works is
-
12:18 - 12:22it increases the release of a
hormone called oxytocin. -
12:22 - 12:26Oxytocin is released from the brains of
breastfeeding mothers. -
12:26 - 12:29It's a hormone that engenders a sense of
attachment and bonding. -
12:29 - 12:33And that's what's happening in the
patient who takes MDMA. -
12:33 - 12:36And also it acts directly on
the amygdala to reduce -
12:36 - 12:41that fear response whilst at the same
time boosting the prefrontal response, -
12:41 - 12:44allowing the patient to see things in a new light.
-
12:44 - 12:46A positive light.
-
12:46 - 12:48So let's go back to Claire.
-
12:48 - 12:50She's 40 now.
-
12:50 - 12:53She's been in and out of psychiatric hospitals,
-
12:53 - 12:55having tried to take her own life
and the inception. -
12:55 - 12:59She's been on all the antipsychotic and
antidepressant mood stabiliser drugs. -
12:59 - 13:02She's tried all the psychotherapies
but she cannot engage -
13:02 - 13:06because she will not talk about her feelings.
-
13:06 - 13:11So she comes into a course of
MDMA-assisted psychotherapy. -
13:12 - 13:13What does it look like?
-
13:13 - 13:18It's weekly sessions, maybe eight, ten,
twelve weeks long. -
13:18 - 13:21There're two therapists, male-female pair.
-
13:21 - 13:25You do not take MDMA everyday,
you do not take it every week. -
13:25 - 13:29Over that course of 12 sessions you'll
take the MDMA three times and the -
13:29 - 13:34other sessions you talk about the material
that's released on the MDMA session. -
13:35 - 13:40So what does Claire actually feel
when she takes this MDMA? -
13:40 - 13:46What she feels is a sense of warmth and
understanding and a sense of containment -
13:46 - 13:51within that relationship she's having
with the therapist. -
13:51 - 13:56MDMA is like a lifejacket like
a bulletproof vest -
13:56 - 13:59to wear to go into battle with your trauma.
-
13:59 - 14:01This is not ecstasy!
-
14:01 - 14:06She's not enjoying some raver's euphoric
ecstasy delight. -
14:06 - 14:11This is still trauma focused psychotherapy
and it's still hard and distressing for her, -
14:11 - 14:15but she can just about do it with
MDMA on board. -
14:15 - 14:20So when the therapist says:
"Claire, tell me about your rape". -
14:20 - 14:22In the past just the word rape
and she'd be out the door, -
14:22 - 14:26but on MDMA she says:
"yeah, I can talk about that! -
14:26 - 14:32I can see him now coming into the room.
I can smell the whiskey on his breath and -
14:32 - 14:36I can feel the stubble on his face
as he's raping me". -
14:36 - 14:40And she talks about it and she explores it
and she reflects upon it -
14:40 - 14:43and she can begin the process of healing.
-
14:43 - 14:46And from here she can start her journey.
-
14:46 - 14:49She can attack the root cause of her problems.
-
14:49 - 14:53Not just maintain the symptoms at a level.
-
14:55 - 14:57So, does it work?
-
14:57 - 14:59Well, we've known about MDMA
for very long time -
14:59 - 15:05and indeed we've used MDMA in
underground therapy for 30 or 40 years. -
15:05 - 15:07And there are thousands of
positive anecdotal cases. -
15:07 - 15:13I get five emails a week from all over the
world: "Dr. Sessa, I've had PTSD for years. -
15:13 - 15:17I've tried everything and now I tried MDMA
and I'm starting to make a breakthrough!" -
15:17 - 15:21Now, anecdotal reports like that are
interesting but they're not science so -
15:21 - 15:23we've done the science.
-
15:23 - 15:26And some important studies in recent years.
-
15:26 - 15:33Big study in the States showed that a single
course of MDMA therapy, 16-week course, -
15:33 - 15:36patient takes MDMA three times
tested against a placebo. -
15:36 - 15:44At the end of that course 85% of the people no
longer met the diagnostic criteria for PTSD. -
15:44 - 15:49Not just a relief of symptoms,
they didn't have PTSD! -
15:49 - 15:54Now that cohort were then followed up
three years later, the same no PTSD. -
15:54 - 15:58Many of those people had come of
their daily medications. -
15:58 - 16:03They were cured! We don't use
the "cure" word in psychiatry. -
16:03 - 16:08We've become learned helplessness
position of--This is the truth! -
16:08 - 16:12If you're diagnosed with a severe
mental disorder like anxiety or depression -
16:12 - 16:17in your 20s, and the developmental route
of that disorder is severe child abuse, -
16:17 - 16:19there's a pretty good chance chance--
and I'm sorry to say this-- -
16:19 - 16:22there's a pretty good chance you
will still be going to -
16:22 - 16:25psychiatric clinics in your 60s and 70s.
-
16:25 - 16:31Now that is not good enough and we're in this
position because we're not tackling trauma. -
16:32 - 16:35So, it works but is it safe?
-
16:35 - 16:40When we talk about safety of
clinical MDMA, what we must not do is -
16:40 - 16:44look at the risks of recreational ecstasy.
-
16:44 - 16:47I don't even know what ecstasy is anymore!
-
16:47 - 16:49Ecstasy is over here, what is ecstasy?
-
16:49 - 16:53Some dodgy pill bought in some
dodgy club of some dodgy geezer, -
16:53 - 17:00that may or may not contain MDMA plus or
minus whatever far more toxic substance. -
17:01 - 17:06When you hear about the very high-profile
deaths of people who take ecstasy, -
17:06 - 17:10it invariably is not MDMA.
-
17:10 - 17:13So, let's not look at ecstasy as a
measure of MDMA. -
17:13 - 17:16Let's look at clinical MDMA.
-
17:16 - 17:21When you use clinical MDMA, you take it
under medical supervision. It is pure. -
17:21 - 17:26The MDMA that I'm using in
my studies is 99.98% pure! -
17:27 - 17:31Very expensive!
(laughter) -
17:31 - 17:35We do it under medical supervision with
a doctor and a nurse and a psychologist. -
17:35 - 17:40And under those conditions the risks are
reduced to a absolute minimum. -
17:40 - 17:43Indeed, after 40 years of MDMA research,
-
17:43 - 17:48there has not been a single serious
adverse drug reaction, not one! -
17:48 - 17:51And certainly no deaths.
-
17:51 - 17:54So, we need to do this research and
-
17:54 - 18:00we need to do this research in
an evidence-based, compassionate way. -
18:00 - 18:02Looking at the data.
-
18:02 - 18:05We need to ignore the socio-political
agenda that says any drug -
18:05 - 18:11that's being used recreationally must
also be very bad and dangerous. -
18:11 - 18:14That sort of attitude hampers research.
-
18:15 - 18:18And we need scientists to drive this.
-
18:19 - 18:21It works, it's safe.
-
18:21 - 18:25And it offers patients like Claire for the
first time in their life an opportunity -
18:25 - 18:30to break through from that trauma and not
become a lifelong chronic PTSD sufferer. -
18:30 - 18:33So, where were we going with MDMA research?
-
18:33 - 18:36Well, we've had some studies,
we've got more coming here. -
18:36 - 18:40I'm doing a study in Cardiff with neuroimaging
in which we're going to give patients -
18:40 - 18:44with PTSD, MDMA and placebo and
we're going to look at that relationship -
18:44 - 18:47between the amygdala and the
prefrontal cortex. -
18:47 - 18:54We're doing a study here in Bristol giving
MDMA to patients with alcohol use disorder -
18:54 - 18:58because underlying the root
of this addiction is trauma. -
18:58 - 19:00This is an exciting time.
-
19:00 - 19:02Now people say: "This is controversial!"
-
19:02 - 19:04And indeed, I was introduced
as a controversial speaker. -
19:04 - 19:08I'm not controversial, I'm a very boring
conservative doctor. -
19:08 - 19:10I like data.
-
19:10 - 19:14I like evidence-based data that
helps my patients. -
19:14 - 19:16I'll tell you what's controversial!
-
19:16 - 19:21What's controversial is that more people
have died returning from Afghanistan and Iraq -
19:21 - 19:24because they've committed suicide
because of their untreated PTSD -
19:24 - 19:27then ever died in the conflict out there.
-
19:27 - 19:31That is controversial and that is unethical!
-
19:32 - 19:35So, this is an important time for science.
-
19:35 - 19:40MDMA could be the antibiotic that
psychiatry has been waiting for. -
19:40 - 19:44We owe that population of patients
who are being failed, -
19:44 - 19:46we owe them this research!
-
19:46 - 19:48We owe this Claire!
-
19:48 - 19:55Thank you.

- Title:
- Is MDMA psychiatry’s antibiotic? | Ben Sessa | TEDxUniversityofBristol
- Description:
-
This TEDx talk will explores the practice of MDMA Psychotherapy, illustrated with the life-story of a fictional typical patient. We owe it to this population of vulnerable, untreated patients with unremitting mental disorders due to psychological trauma, to explore MDMA Therapy as potential new treatment for the future of psychiatric medicine.
Ben Sessa is a consultant psychiatrist in adult addictions, working part-time at Addaction in Weston-Super-Mare and is senior research fellow at Bristol, Cardiff and Imperial College London Universities, where he is currently taking part of his time away from clinical medical practice to study towards a PhD in MDMA Psychotherapy. He is the author of two books exploring psychedelic medicine; The Psychedelic Renaissance (2012) and To Fathom Hell or Soar Angelic (2015) and is currently conducting research with Imperial College London and Cardiff universities studying the potential role for MDMA-assisted therapy for the treatment of PTSD and alcohol dependence syndrome. Dr Sessa is outspoken on lobbying for change in the current system by which drugs are classified in the UK, believing a more progressive policy of regulation would reduce the harms of recreational drug use. He is a co-founder and director of the UK’s premier international psychedelic conference, Breaking Convention.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
