Postpartum Depression

Liang A

Clinical Cases Applicability: Antepartum mood disorders, postpartum blues, postpartum depression

Learning Objectives:

1. Understand the neurobiological mechanisms underlying postpartum depression

2. Describe the pharmacology of SSRIs

What are some sex differences in depression?

-Women 2x more likely to develop depression, greatest difference in reproductive years – suggests sex hormones (estrogen, progesterone, oxytocin) and reproductive events play some role in etiology of depression

What is the definition of PDD? prevalence? Risk factors? Natural history?

-DSM 5 defines peri-partum depression as symptom onset during pregnancy or <4 weeks PP – but greatest incidence of new PPD occurs 2-3 months postpartum, and can occur within 1 year

-Prevalence ~10-15%

-Risk factors: antenatal depression (↑ prevalence in 2nd/3rd trimesters) & depression prior to pregnancy; stressful life events (marital conflict, emigration), poor social & financial support

– Often remits on its own within 12 months after giving birth, 6x increased risk for depression later in life

What are proposed neurobiological mechanisms underlying PPD? Pathogenesis unknown

Genetics: increased risk with family history of PPD

Abnormal neurotransmitter levels/activity: ↑ brain monoamine oxidase ↑ metabolism of neurotransmitters such as dopamine, norepinephrine, serotonin more rapid depletion of these neurotransmitters depression

Significant changes in neural activity in brain regions important for self-regulation, empathy & emotion; fMRI studies identify brain regions affected by postpartum depression at rest and in response to infant or non-infant emotional cues

Decreased corticortical and corticolimbic connectivity

-Weaker connectivity among the amygdala (processes emotions), anterior cingulate cortex (connects the “emotional” limbic system and the “cognitive” prefrontal cortex), dorsal lateral prefrontal cortex (working memory) & hippocampus (long term memory, emotional responses)

-decreased connectivity between the amygdala and right insular cortex w/ positive infant cues

Abnormal growth factors: ↓ Brain-derived neurotrophic factor (supports differentiation, maturation and survival of neurons) concentrations in PPD

What hormones may play a role in PPD? women with a predisposition for depression may be more sensitive to large fluctuations in steroid hormone levels

Estradiol: estradiol levels continue to ↑ in 3rd trimester, but drop dramatically after birth “estradiol-withdrawal state”

Cortisol: high levels of cortisol during pregnancy secondary to placentally-derived CRH; cortisol stimulates CRH production in placenta (positive feedback); withdrawal from excess cortisol postpartum (figure 1)

Oxytocin: hypothesized to have anti-depressant properties; women at risk for PPD have lower oxytocin concentrations in 3rd trimester; BUT administering oxytocin does not improve mood

Why is treatment of PPD important?

Negative outcomes for mothers and infants: ↓ breastfeeding, lack of maternal emotional and behavioral sensitivity to the infant, poor bonding, negative infant temperament, atypical neurodevelopment, and later emotional and behavioral problems for the children

What are pharmacological treatment options for PPD? Mechanism of action? women with PPD take longer to recover & require more therapies than in non-postpartum MDD women

SSRIs – paroxetine and sertraline usually undetectable levels in breast-fed infants; SSRIs block the SERT transporter to ↓ presynaptic serotonin reuptake↑ serotonin concentration (figure 2) Postpartum Depression

00:00
hey guys I’m sorry it has been a little
00:02
while since I filmed a YouTube video but
00:04
I just wanted to sit down today and do
00:06
one because I’m finally feeling a little
00:08
bit better I just had no motivation
00:09
there for a while
00:10
you guys know how it is with PMDD um it
00:13
gets really rough so I’m just now like
00:16
getting off of my period so I’m feeling
00:19
a little bit better and I asked you guys
00:22
on Instagram what YouTube videos you
00:24
guys wanted to see and I got a lot of
00:28
really good suggestions so thank you
00:30
guys for that I’m going to be you know
00:32
working my way through the list but one
00:36
of the suggestions stuck out to me it
00:40
was um what are your worst PMDD symptoms
00:42
and so I figured today I would share
00:44
with you my top 5 worst PMDD symptoms
00:47
and the reason I’m doing this is because
00:49
I just think it’s interesting like to
00:52
hear each woman’s like worse symptoms
00:55
and how we you know get different things
00:58
or how we can relate at this like the
01:00
same things and all of that stuff so I’m
01:03
just gonna go in order from like not as
01:06
as bad to like the very very worst so
01:08
like 5 4 3 2 1 if that makes sense all
01:11
of these symptoms are terrible
01:14
they’re my top 5 so they’re really bad
01:16
and it’s almost hard to rate them on a
01:19
scale of like not as bad to worse
01:21
because they’re all just so bad
01:23
but I am going to just jump right in to
01:28
number 5 and that is sore breasts I get
01:33
the worst breast tenderness and pain and
01:35
they swell up like a whole cup size and
01:37
they feel like they’re bruised like like
01:40
I’m carrying sandbags around in them and
01:42
they’re bruised like it hurts so bad and
01:45
I can feel it when I walk like I can
01:48
literally feel it when I take a step
01:49
it’s that like sensitive and severe now
01:52
I just wear really tight bras honestly
01:55
during that time and sometimes I’ll even
01:57
ice my boobs like I’m not even getting
02:00
it it gets really really bad and for me
02:03
it happens for ten days of every month
02:05
so 10 days warm period I’ll start
02:08
getting breast tenderness and it will
02:09
last all the way up until I start my
02:10
period
02:11
so that is no fun at all and I’m sure a
02:15
lot of you can relate to that but yeah
02:18
not a good time my second art number
02:21
four I guess I would say is my increase
02:24
in appetite I get the worst cravings and
02:28
they are horrible it’s mostly for pizza
02:31
and chocolate I will literally go out of
02:34
my way to seek out pizza and I’m not
02:37
even supposed to eat pizza I’m gluten
02:38
and dairy intolerant and I will eat it
02:41
anyway that’s how much I want it like
02:43
that’s how bad and overbearing my
02:45
cravings get I’m just like fuck the food
02:46
allergies like I’m gonna get pizza and
02:48
then I end up paying for it later but
02:51
yeah I eat pizza a lot when I’m PMSing
02:54
it just sucks because like I really do
02:56
try hard with my fitness and my healthy
02:58
eating and I don’t have a problem with
03:00
it during the rest of the month but then
03:03
like that two weeks before my period I
03:05
get so like almost out of control and I
03:08
just crave everything and like it’s
03:11
normal for us to have cravings but with
03:13
PMDD it’s like PMS on steroids so
03:15
everything is way way worse and I
03:18
honestly could not even like Express to
03:23
you guys how strong my cravings get it
03:26
really sucks and that’s just that was
03:29
that one’s worse for me than the sore
03:31
breasts because I can handle the sore
03:32
breasts but the appetite thing drives me
03:34
fucking nuts because I’m already bloated
03:37
I’m already miserable and then to add
03:39
like all that food into my stomach and
03:42
all the bad food and for me to try to
03:44
process that like and it’s like well why
03:47
don’t you just control what you eat it’s
03:49
like I almost nearly can’t like it’s
03:51
just it’s so overbearing and that’s
03:55
something I’m excited about to get my
03:56
hormones leveled out hopefully with this
03:59
new birth control that I’m about to try
04:00
which I can make a video on later but I
04:04
just literally can’t stand how bad the
04:07
appetite is like it’s it I will gain I
04:10
think I go up six pounds within two
04:14
weeks like I will gain six pounds and
04:16
then I’ll lose six pounds and I’ll gain
04:17
six pounds and lose six pounds it’s like
04:19
this vicious cycle that I’m always in
04:21
because
04:21
I can’t stop my cravings okay so the
04:26
next one number three is gonna be lack
04:29
of motivation
04:30
this one’s horrible because I can’t get
04:33
anything done when I’m doing when I’m in
04:35
my PMDD time like my two weeks I just I
04:38
I can do the bare minimum but that’s all
04:41
I have the motivation for it’s all I
04:43
have the energy for I’m sure a lot of
04:46
you can relate to that one as well it’s
04:47
just like nothing interests me nothing
04:49
even fun like I don’t even have the
04:51
motivation to go do something fun so
04:53
that’s like how bad it gets you know
04:55
it’s like I just have the motivation to
04:59
lay in bed that’s about it I still do
05:02
try to get myself to the gym and I
05:04
obviously get myself to work because I
05:05
have to but other than that like that’s
05:09
kind of like where I keep it at and
05:11
that’s why a lot of times I can’t bring
05:13
myself to make youtube videos during
05:14
that time or post on Instagram because
05:17
I’m just so overwhelmed with how sad and
05:22
exhausted and depressed I am that I have
05:25
no motivation and it’s a typical symptom
05:28
of depression so it makes sense that
05:30
like with how depressed we get as PMDD
05:32
sufferers that we would experience a
05:35
lack of motivation but that one just
05:37
really sucks they all suck
05:38
Who am I kidding okay and number two
05:42
what so Mike this is close to my worst
05:45
one is the fatigue I wrote them all down
05:49
on my phones that’s why I keep laying
05:51
down is the fatigue that I get so this
05:54
kind of goes along with lack of
05:55
motivation but it’s a different symptom
05:57
because it’s just in and of itself it’s
05:59
a whole entity like I get so tired
06:03
people like will make fun of me because
06:04
I’m sleeping so much and it kind of
06:06
sucks because honestly I can’t help it I
06:08
can’t help that I get that overwhelm and
06:10
tire like fatigue and I will sleep 14
06:14
hours a night and then take naps during
06:15
the day and that’s no exaggeration like
06:18
I was just texting someone the other day
06:19
and he was like 14 hours like you slept
06:22
14 hours and I was like yeah like cuz I
06:25
had texted him before bed and I texted
06:27
him when I woke up when he was like you
06:28
just woke up and I was like yeah like I
06:31
can’t help it it’s just like and he
06:33
wasn’t like making fun of me or you
06:34
but um people will like be like oh my
06:38
god you sleep so much and I’m like I’m
06:40
sorry like if you had PMDD you would
06:43
understand like because our bodies are
06:45
so intolerant to the hormone shifts that
06:47
we just get so wiped out and I remember
06:51
even before I developed PMDD as like a
06:53
13 year old I when I first got my period
06:56
I I remember like the first time I was
06:58
on my period I like came home from
07:00
school and just fell asleep on the
07:02
loveseat like in the weirdest position
07:03
like I was in the Hat tired and I have a
07:06
lot of energy as a young girl so that
07:09
was really unusual for me so I’ve always
07:10
been someone that’s just completely
07:11
wiped out by PMS slash period the
07:14
fatigue will last like the two weeks
07:16
before my period and then like halfway
07:18
through my period and then finally one
07:20
day I’ll wake up and be like okay I have
07:22
a little bit of energy and not so so
07:24
tired that I can’t do anything so that
07:26
is number two then finally number one
07:30
and this one is hard to talk about this
07:32
one is triggering so I’m just gonna put
07:35
a trigger warning right here just
07:38
audibly say trigger warning is the
07:42
suicidal ideation and thoughts and you
07:47
know thoughts of harming myself I get
07:51
them almost every month
07:53
pretty much every month and they do last
07:55
a couple weeks I have to just push them
07:58
out of my brain or just wait until they
08:00
go away and kind of just chill and you
08:03
know do something that soothes my mind
08:05
like watch a show or you know read a
08:09
book or talk to a friend something that
08:13
distracts me from like thinking like I
08:16
want to die because it’s an awful
08:19
thought and when you have that thought
08:20
it’s really really overbearing you can’t
08:23
really think about anything else no
08:24
matter how hard you try so it’s just
08:28
really hard to feel that way for half of
08:30
the month every month because it adds to
08:33
the fatigue it adds to the lack of
08:34
motivation it just adds to the heaviness
08:37
that we feel as PVE sufferers and I
08:42
can’t even express to you how low I get
08:45
during these times
08:47
like like last month I woke up for work
08:51
I was feeling absolutely atrocious I
08:53
didn’t think that I could make it
08:55
through my shift I ended up making it
08:56
through but it was really really hard
08:58
and I was sobbing to my mom and I said I
09:02
can’t go to work today like I want to
09:03
die I just want to die and now it’s like
09:08
every month when I feel better and I
09:10
look back at that version of myself I
09:12
think how could I possibly feel that bad
09:16
but then I feel that bad again and again
09:19
and again and again and I remember how
09:23
awful it is and I hate it I hate it with
09:27
everything I have I would never wish
09:30
this upon my worst enemy like it is the
09:32
worst absolute worst feeling to feel
09:34
like you don’t want to be on this earth
09:36
anymore
09:38
yeah that’s a heavy one and I’m sorry
09:41
about that I know that’s hard to hear
09:43
and it’s hard to talk about because it
09:45
can be triggering and it can be really
09:48
heavy to put on somebody to hear that
09:51
and to talk about but it is necessary
09:54
that we do talk about it because it’s
09:56
something that a lot of women with PMDD
09:58
experience regularly and so to talk
10:04
about it is to bring awareness to it and
10:06
so hopefully you know we can get more
10:09
awareness and reduce the stigma of pmed
10:11
and suicidal ideation and all that but I
10:15
have to say that’s my number one where
10:16
symptom it it’s the worst feeling I I
10:21
come in I can’t even put it into words
10:23
how bad that feeling is where you want
10:25
to die yeah
10:29
I’m that’s just pretty much all I have
10:32
to say about that sorry to end on a
10:33
heavier note but yeah that was my worst
10:38
symptom for sure and it’s it’s my worst
10:40
symptom it’s what I meant to say and
10:42
yeah so those are my top five worst
10:46
cambini symptoms
10:48
let me know what you guys think I want
10:50
to hear what your top five worst ones
10:52
are I want to hear if they’re similar to
10:54
mine if you have different one there’s a
10:56
lot of symptoms I didn’t mention in this
10:58
video
10:58
that I get so don’t think that I don’t
11:01
experience other things just because I
11:03
didn’t mention them I just wanted to
11:04
mention the top five that I think are
11:06
the worst for me personally but I would
11:08
love to hear you guys opinions and
11:10
thoughts and all that so leave a comment
11:12
