The Biology of PTSD

Published: Aug. 26, 2022, 1:59 p.m.

Post Traumatic Stress Disorder (PTSD) is recognized as a significant issue that can affect people in everyday life. The sum total of small traumas can have the same biological effect as those experienced in combat. It is important for therapists and clients to understand the biology of this process to best help those dealing with this potentially debilitating issue.

you're listening to psych with mike for more episodes or to connect with the show with comments ideas or to be a
0:06
guest go to www.cyclicmike.com follow the show on twitter at psych with
0:13
mike or like the facebook page at psych with mike now here's psych with mike
0:21
welcome into the site with mike library this is dr michael mahon and i am here again with intern michael and brett
0:26
newcomb once more dear friends into the fray that's what i i'm leaving into the breach into the breach yeah yeah
0:33
i hadn't started the quotation yet you you say that every time i never mind say that once
0:40
okay and then i say oh yeah you're a shakespeare guy and then you say no i'm not i'm not like oh yeah you always
0:46
quote shakespeare i'm a liar okay
0:54
all right so how's everybody doing today doing well um you
1:01
said some incredibly nice things about intern michael before
1:07
the mics were hot and you don't say those things to me and i'm jealous isn't that interesting isn't
1:13
that interesting i wonder why you're going to have so are you begging what do you want i think nicest not no
1:19
yes you are so
1:25
yeah i secure need those that's what it is i don't know i feel like i got a little post traumatic your wife has asked me to stop blowing smoke in your
1:31
direction you inhale too much of it your shirt looks nice today michael thank you
1:37
thank you i appreciate that so uh so speaking of ptsd speaking of
1:42
yeah um this is not your forte right
1:48
it's not a biology not this aspect right yeah um so you're gonna try and hang with it and see i'm waiting for clear
1:55
elucidation from michael yeah because i know all you'll do is build a clock well the reason why for me
2:03
the biology is important is because understanding the biology helps me to
2:10
understand the concept and i understand i get that that isn't everybody's cup of tea but i've had
2:17
clients who have said the reason that i come to you is because you understand the biology
2:23
really well and you are able to explain that and that's really meaningful and that's why uh i have always said you know there's
2:30
different therapists for different people not all therapists are going to be for everybody but
2:36
a person shouldn't assume that just because they go to one therapist and that wasn't for them that that means
2:43
that therapy doesn't work no i and i and i can conceptualize being able to get some
2:50
comfort from saying i'm really sorry about the way that i behaved when i lost my temper and
2:55
slapped you but it wasn't really me it was my amygdala i'm sure that will help her
3:01
that's not exactly what the article talks about oh it is exactly what the article talks
3:08
about it doesn't say that you say i'm sorry that i said no it doesn't say that it says you need to understand that your
3:14
amygdala is out of balance and that's why you have these reactions when your stress triggers are pulled well so
3:21
the idea here that i think is so important
3:27
for both clients but also for therapists to understand is that
3:33
instead of thinking about anxiety as a
3:39
thing what we really need to start doing as a i think as a community of helping
3:46
professionals is to start thinking about the difference between anxieties and
3:51
fear-based anxieties because the way in which those things operate in the brain
3:58
are vastly different okay
4:03
so i if i can paraphrase just a little bit yeah understanding of the biology can help
4:11
drive the therapeutic approach because fundamentally there are
4:17
different mechanics underlying what may appear to be the same consequence but isn't
4:23
necessarily the same concept exactly and and i don't hear this being talked about
4:28
a tremendous amount this is what i did my dissertation on and i don't hear this being talked about a tremendous amount
4:34
in psychology but i do believe that in the future we are going to see exactly
4:40
that distinction instead of talking about depression and anxiety as two
4:45
sides of the same coin i think we have to think about depression as a separate
4:50
entity anxiety as a separate entity but within anxiety the generalized anxiety
4:57
disorders and the fear-based anxiety disorders
5:02
okay okay so in a regular anxiety disorder so just the
5:08
kind of run-of-the-mill generalized anxiety disorder what i say is that those things operate on the concept of
5:16
cognitive dissonance so you have two conflicting thoughts that causes distress in the human brain trying to
5:23
resolve that is what creates the energy for anxiety that
5:28
most people feel so i want to go to the grocery store but i have agoraphobia
5:34
and i don't want to go to the grocery store so that conflicting thought is going to cause me a lot of anxiety
5:43
even easier for i worked with a lot of adolescent males that's typically what i
5:48
do and when an adolescent male comes in and says hey i want to ask this girl out but
5:55
he treats it as if it's a schrodinger experiment where he wants to ask her out but he's afraid of creating
6:02
the answer so he lives in this perpetual world of i could ask her out but i could
6:09
also you know then be uh what do you call it rejected and then
6:15
then you know that's scary so i don't ask her out now i'm living with both of those things potentially available to me
6:23
i could ask her out and or i could not ask her out and and that's what i think is generalized
6:28
anxiety so that operates on the same kind of top-down brain function where your the
6:36
the cortex of your brain operates on the information and then informs your limbic system whether or not there's a reason
6:41
to become excited and then if there is a reason to become excited then your adrenal gland tells or or your pituitary
6:49
gland tells what gland to distribute the hormones to start an emotional reaction
6:55
that's slow responsible yeah yes exactly so that's typically the way the brain works is top down in ptsd or in
7:02
fear-based anxieties that gets flipped on its head so that the immediate activation
7:09
of the brain are the fear-based response areas like the cerebellum like the
7:17
medulla oblongata and then that causes a fight-or-flight response to be initiated
7:24
over which the person has no rational control so an individual who's been in
7:31
combat and has seen horrible horrible things and then gets triggered by a car
7:37
back firing the response that gets activated in that person is not a
7:43
top-down response it's a bottom-up response and so in those fear-based anxieties the
7:50
way in which the individual is triggered is radically different and if you don't
7:56
appreciate that in therapy then you could be treating that
8:02
inaccurately and appropriately or ineffectively so that's my my
8:07
conceptualization in a nutshell so you're following me so far i think so okay do you agree with that
8:13
or yeah absolutely okay i don't have any trouble understanding the concept i have trouble understanding how to
8:18
apply it um in counseling clients which is my
8:23
primary frame of reference i also have
8:28
some issues and been able to sort out anxiety from depression because they're often
8:34
comorbid and if you in my experience if you deal with one of them if you can alleviate a level of
8:40
intensity for anxiety the depression explodes then you have to do that and you need to
8:46
tell the client this is likely to happen and when it does it doesn't mean what we're doing is not
8:52
working it doesn't mean that you're unable to change it means that's part of what's stuffed down inside you and we're
8:58
going to have to come to grips with yeah then you have taught me a lot
9:05
over the years about the biology of depression and the issues there
9:11
in terms of chemical responses and so on it's just really um
9:19
an incredibly complicated challenge to then say however much of that i understand
9:25
how do i apply what i understand to hearing the client accurately and being helpful to them and that's where i get
9:31
lost in this conversation so for me and and what i would say is
9:37
the extent to which an individual therapist understands or wants to understand
9:43
better the biology of these different disorders is whatever it is and and i'm not saying
9:50
that everybody has to be a neurobiologist but what i am saying is that specifically
9:55
in the venue of anxiety it is very very important to identify
10:01
whether you think the anxiety is just a generalized anxiety disorder or it's fear i see that
10:07
uh and i see the value of the merit and saying okay this is a
10:13
reflex driven fear anxiety that you'll see triggered in this way when a car back fires or when a door
10:19
slams a loud noise goes off so
10:25
if we know that you're susceptible to that can we take that piece out and work on it loud noises anticipating it
10:33
responding to it differently because you're conditioned by the trauma experience to have this response
10:39
immediately overwhelmingly then the generalized anxiety is is a different issue
10:45
that we want to approach differently is am i understanding what you're saying absolutely and and so then when we think about
10:52
individuals who have experienced childhood traumas right so for a person
10:58
who has been abused by a family member sometimes it's hearing the creaking of
11:04
the floorboards yeah there's some research that shows that that's imprinted on these children if it happens in an early enough age
11:10
and so their response to that almost as hardwired in your brain yeah but it is hardwired when i i think
11:17
you're asking the question how do i use this to guide my practice yeah uh and maybe one way that i'm seeing
11:24
uh as an opportunity here is to think of the brain as taking the path of least resistance with different experiences
11:32
so in the instance of ptsd right we're saying that we no longer have to involve
11:37
the the prefrontal medial cortex right we no longer have to involve this expensive
11:42
part of the brain to deal with the same reaction as a brain
11:48
that we would around certain events so car backfiring is gunshot
11:54
floor creaking is fear in a child right um for whatever abusive reason
12:01
maybe as a clinician understanding that that is the current path of least
12:06
resistance says exactly what you're saying already we need to take that out look at that as a part and find other
12:13
paths that work better because that's no longer serving okay right no longer
12:20
this is actually more resistant and i think that that really fits in very well with your idea of emotional
12:28
economics so is this old behavior too expensive yeah yeah
12:33
yeah and and would you like to try and investigate other avenues that helps i
12:39
mean i have to have a way to frame it i have to have a way to hear it and when i read these articles
12:44
that in what happens to me so i need a better
12:52
modulator no not not analogy so much as uh i need a better understanding of how
12:59
this is applicable as you were suggesting i think one of the places that uh i i am by no means an expert
13:06
right but one of the things that i see keep popping up um is bessel vander kulk's work
13:12
the body keeps the score um he's a medical doctor that's gone into this foray of of um
13:18
psychology really one of the trauma i mean trauma informed therapy is his whole deal exactly one of the foundational uh creators and
13:25
understanders of ptsd as a as a condition um and i really did like that book i think
13:32
that book does help frame an idea of why is some of the biology important or like
13:38
how can it drive my practice so i have met and talked with and read a
13:44
book by dr mark gordon who's a neurophysiologist and he does a lot of work on traumatic
13:51
brain injury for the military and much of that work is focused on what's his name
13:57
mark gordon and much of his work is focused on
14:03
the biochemical aspects of the brain and where the brain injury occurs and how
14:09
the system adapts and responds and what needs to be rebalanced
14:14
biochemically so that you can then do other things it's a it's a whole area that i don't know
14:21
enough about to talk about or do work with but i think it's in line with what we're discussing i think it
14:28
comes back to some of the philosophies that i have around psychiatry right psychiatry is
14:34
a medically assisted therapy overall right it's drug assisted therapy but
14:39
overall the point is still the therapy right i would hope
14:44
we know that a lot of the time uh antidepressants or anti-anxiety or even
14:50
things like antipsychotics aren't as effective as they could be they they're they have
14:56
a five percent difference in the overall efficacy without therapy included
15:03
so i look at understanding the biology as just another tool to help assist this idea of getting
15:09
somebody back to a place of security and getting somebody back to a place of um being in control of what they want
15:16
exactly okay so let's take our break and when we come back i'm going to ask you a question brett all right
15:23
well one of the reasons that i want to participate in this show is because it gives me an opportunity
15:29
to clinically review my understanding of what therapy is and
15:34
how it works especially for the consumer so my hope is that we will find
15:41
conversations that broaden my understanding of that and my hope is that we do that in a way
15:49
that is useful but also entertaining for people so that they want to listen
15:56
not only because they're getting good psychology information but because they
16:01
just enjoy the show easy listening with an informational twist
16:06
that's a new tagline they're not sitting there going huh easy listening with an informational twist i'm really good at
16:12
this i'm a professional you're a professional if it's friday it's psycho
16:18
okay we're back and so uh does the idea or the the language of the
16:24
emotional economics does that make that the the what what yeah that all makes
16:29
more sense to me that's the language i can hear yeah i get bogged down in the analysis of the prefrontal cortex and
16:36
the amygdala and all that that to me is not a language i'm comfortable
16:41
and you make a great point though that that therapists who are doing therapy to the extent that they're not comfortable
16:47
with that then they're not going to hear that message all i'm talking about is the first thing you got to do when
16:53
you're dealing with an anxiety is to identify whether or not it's generalized anxiety or fear-based anxiety and then
16:59
and the most obvious way for you to know that is what well for me what i would say is
17:05
whether or not you think that the anxiety is based on cognitive dissonance
17:11
so is it is it what i'm hearing is if it's a global reflexive response boom
17:17
yes then that's on the floor ptsd yeah yeah uh yeah and so when i'm talking about kind of
17:23
distance you know do you see the anxiety as based on two conflicting thoughts
17:28
that the individual is trying to harbor give me an example
17:34
so uh uh i want to ask a girl out but i'm afraid to ask her out okay so that's not you know that's not
17:40
interesting anxiety okay yeah that's generalized anxiety and then you know i'm i hear the floor creek and i'm
17:48
terrible that's like albert ellis with rational emotive therapy uh the experiment that he offered you
17:54
know a guy that claimed i could never have sex with him and he said i want you to stand on the street and ask the first 100 women that
18:00
walk by if you can you have sex with me and you'll get slapped you'll get rejected
18:06
the police may be called but you know four out of 100 they'll say sure let's go and you're not going to know whether
18:12
it's real or not unless you do it mm-hmm so he would give people assignments like that
18:18
which you couldn't do today but well you can't really well yeah yeah
18:23
you have to deal with the clarification anticipatory set right right so uh
18:29
in my view then if you are if you've identified that you are dealing
18:36
primarily with a post-traumatic stress disorder then the first thing that you
18:41
have to do is to try and find some way into that because
18:48
what you have to recognize is that a lot of the techniques that we use in therapy
18:54
are directed at talking to the person's cortex you got to have rational thought
19:00
so cbt is an approach that's often recommended for post-traumatic stress yeah may not
19:06
be as effective because that's not really the right part of the brain yeah you're not talking about exactly exactly
19:12
so then we get things like emdr emdr here's where we start to move into let's get out of the head and start
19:19
feeling the feelings we we're having a good conversation about this earlier yeah well and feel those feelings
19:26
and you don't understand those feelings and find a way to redirect that energy
19:34
but i also think that that brett's idea of emotional economics when he talks
19:39
about that what i hear and i don't know if this is what you intend but
19:45
what i hear is that that's affective aff ect emotion-based therapy that's not
19:52
cognitive behavioral therapy when you're talking about emotional economics that is the way to approach the
19:59
post-traumatic stress disorder when we're talking about it's an activation of those baser areas of the brain you're
20:06
not going to approach that by talking to somebody's cortex you're going to approach that by talking to their limbic
20:12
system to their emotions so we're back to what does the therapist need to know in
20:17
order to do what they're doing and how much of that is even relevant for the client to know so if i'm talking to you about emotional
20:24
economics i'm not going to have this more extended exactly you don't have to now yeah i would i know you know but for
20:31
me that's a waste of time i know okay and well i think part of that conversation is valuable right in in
20:37
behavioral economics and emotional economics we talk about the idea that people have biases and those biases
20:42
aren't necessarily rational right and maybe we stare away from the word rational it's also a
20:48
message of power there's an empowerment if i say to you okay you could choose to behave differently
20:54
if you wanted to and if you could afford it you know i could choose to drive a corvette
21:00
but do i want to can i afford it uh what would i do i want you to fight can i afford it yeah what am i willing
21:06
to give to have one so that allows you a weigh-in
21:11
that isn't a direct challenge that they can rebut or refuse to hear
21:17
because you come up with an example or they come up with an example of some behavioral choice driven by cost
21:27
and you know so for me i don't really it doesn't bother me whether the therapist
21:33
talks about the biology or talks about emotional economics as long as they understand that when i am looking at
21:40
this presentation trying to do regular cbt is probably not
21:46
going to be as effective because that's not the area of the brain that this person is operating out of and i think
21:52
that the ubiquity of cbt and now we're talking more and more about trauma and i
21:58
think that there's going to be less effectiveness of that
22:04
of those treatment outcomes because that's not the area of the brain that that person's operating in yeah that
22:10
makes sense ultimately the goal is to move someone from that external locus of control to
22:15
that internal locus of control yeah with cbt emotional economics they're all saying the same thing right of
22:22
i'm putting the power back in your hands to make a choice of this thing which is one of the goals we have when we talk
22:28
about increasing your level of your sense of security if you have the power and the autonomy to make the choices if
22:34
you're free to choose you can freely choose to behave differently and i think that that's the goal so the internal
22:41
locus of control as opposed to the external locus of control is the goal but that's a rational concept so
22:49
initially that person may not be thinking in that area of the brain and
22:54
so you you that may be the goal for the therapist right but that isn't the way you go in to the therapy so the way you
23:02
go into the therapy is through that affective aff ect the the emotional
23:08
economic way however that makes sense to you as a therapist but you have to apply
23:13
some kind of effective therapy so not ptsd per se
23:20
but i had an adolescent male client that was on the autism spectrum and he was really in trouble a lot
23:26
because he would decompensate and act out because kids bullied him and picked on and what have you
23:32
uh and i had to work with the school the teacher the family and the student to
23:38
say is there a way we can get a handle on this and achieve different outcomes
23:44
and it wasn't useful at all to understand or explain where why how is he autistic
23:53
what makes that happen it was more useful we found that to say
23:58
can we find a way to characterize this for him where he can
24:04
feel a sense of power and where he can choose from that power to make different
24:10
choices and so i was able to ask him i said do you want to be popular do you want to be
24:16
liked and he was like yeah i said you have any idea why people don't like you no
24:22
i said well you're a snot sucker you make these horrible noises all the time and people react negatively to it
24:29
and you don't even see it you don't even notice it you just do what you do and i had to work with the teacher on
24:35
like a red card or a yellow card whenever he would suck snot and she could hold it up and he would
24:42
consciously learn to recognize after the fact oh i did that
24:47
and then we worked on could you do something instead like burn your nose is this just a reflexive habituated
24:54
behavior or is there some do you know we need to go to an ent and find something to deal with this which isn't going to
25:01
change the autism spectrum but it can change your acceptability level right and your
25:07
intensity level to maybe a better place sure and and what i would say is that that is an
25:13
example of behavior modification right which is a different
25:19
kind of therapy that we haven't talked about but but at least in this show
25:24
but the initial way you went in was through emotional economics yeah so you
25:31
didn't you didn't start with the behavior modification you started with the presentation of the emotion
25:37
life sucks and you're screwed right you know it it helps to say we can do something with this if you'll work with
25:43
me and if your system will tolerate it yeah and and it goes back to the what michael was talking about when you were
25:50
moving him from an external locus of control to an internal locus of control and all of those things are i mean those
25:57
are the goals of therapy but if you are talking to a part of the brain that
26:03
isn't being triggered it's going to be less effective i'm not saying that no one ever got help through cognitive
26:10
before post-traumatic stress through cognitive behavior therapy but i'm saying that if you think about what the
26:16
biology is my sense my my understanding of human
26:22
pathology tells me to be informed by what i think is the biology and then use
26:30
that to help me to devise a treatment plan that i think is going to be most effective efficient effective economical
26:38
sure yeah then i think further about um other types of therapy modality uh like
26:43
drug assisted therapy so if we look at things like psilocybin assisted therapy or ketamine assisted therapy these are
26:49
really getting a lot of attention right now in the ptsd community and understanding that
26:55
neurobiology and the neurobiological effects of the different drugs what are those pharmacodynamics of those
27:02
different drugs um we can build are you better tool kit are you asking or is that rhetorical it's
27:08
rhetorical okay because you go into 30 minutes
27:13
no i took your addiction and treatment yeah yes and and you know and and i'm not saying that that isn't
27:21
going to be a breakthrough i think that especially for me you know when you're talking about the
27:27
medically assisted treatments for anxiety or for post-traumatic stress
27:32
i think psilocybin is a is a is a more effective molecule than the ketamine i
27:37
agree but uh but there are real reasons why that happens and they're based in
27:44
biology i mean the way in which that the psilocybin molecule opens up the
27:50
connectedness of the brain can allow you to have a conversation with that person
27:57
in a different way that isn't necessarily triggering for them and they can get realizations out
28:04
of that experience that they might not get any other way and and so i think that can be very
28:09
effective is the reverse true for depression with ketamine being the predominant or ketamine is the preferred
28:15
for depression yes and and um i don't know i i don't know my my sense is that the
28:24
reason that ketamine was the initial breakthrough drug was because it was the
28:29
one that they were able to aerosolize and be able to deliver in the context of
28:35
the doctor's visit and the ketamine is a 15-minute reaction
28:41
rather than a six-hour reaction so i mean if you're going to do drug the these these
28:47
psychedelic drug-assisted molecule therapies you're talking that's an all day just
28:52
stay there for 90 minutes afterwards so don't you for the ketamine yeah yeah it's yeah just to make sure that there are no
28:58
adverse reactions but you don't have to stay there for six hours yeah if you took silicibe and you'd be there for all
29:03
day all day oh and just uh just to reiterate that this is another tool in the toolbox right i see a lot of
29:10
instagram ads or snapchat ads for this idea of ketamine assisted therapy
29:16
on people saying oh i feel so much better i feel so much better and there's a real danger in that
29:21
advertisement i think it's important to understand that this is another tool
29:27
in a large toolbox um and isn't the only thing to reach for and might be
29:33
one of the last things you start to reach for other work has to occur first that's right i see the same conflation
29:40
with emdr right people look at the exercise of tapping and they look at different um the light bar exercises and
29:47
that is just so far down the line in emdr and so far removed from the actual
29:53
work that's taking place the emotional lifting that's taking place and especially with what you're saying
29:59
with the the you know the ads but to me that's just like any pharmaceutical agent it's not the
30:07
patient's job to decide what medication is best for them yes and it really burns
30:13
my behind that you have ads on television for any pharmaceutical talk to any physician in america they say the
30:20
same thing about any drug that somebody comes in because they've watched all these ads on tv oh i want this truck and
30:26
that is exclusive to the united states yes um other countries don't not allowed to do it well because it doesn't make
30:32
any logical sense no it's economic yeah i mean a controlled market even if you
30:37
are a doctor you're not supposed to devise your own treatment plan and if you're not a doctor you don't really
30:44
have the informed ability to decide that this medication is a right fit for you
30:49
so yeah i but that point is well taken just because you
30:55
even if you anecdotically know somebody who had psilocybin treatment and that
31:01
person said oh it was great for me it may have been great for them that doesn't mean it's a great choice for you
31:07
but if it is something that you are interested in it is a growing network what happens all the time
31:13
think back about your years of doing therapy with adolescents on adhd medicines right and their family members
31:19
would say oh joey takes this bill why don't you give it to bobby it'll make him better yeah and not involve any kind
31:25
of professional medical or psychological in that loop
31:31
yeah well and this is apropos of nothing but what really burned my behind is that
31:37
i always wanted to know this would always happen or most commonly would happen
31:43
at the end of high school when the person was getting ready to take the act or the sat yeah and then they'd say oh
31:48
well this medication take it on wait a minute no if you're just going to use this as a performance enhancing drug that's not
31:56
the point of the medication yeah but a lot of people used it for that
32:02
tisk disk disk so how how did this strike you
32:08
was the conversation okay uh yeah because we got away from and
32:13
intense analysis of the chemicals in the amygdala and we talked about how that knowledge is useful to a therapist and
32:21
to a person in therapy good good so hopefully good article right we've
32:26
taken something from it to us exactly that's always a good thing
