Aside from our body , medicines
0:17
can affect our mind, too . That's
0:20
how drugs like antidepressants or
0:22
sedatives work , after all . But
0:25
what happens when those effects on
0:27
our behaviour are unwanted ? When
0:34
the medicines we take to keep our health in check alter our personality
0:36
in odd or dangerous
0:38
ways ? My
0:41
name is Federica Santoro , and
0:43
this is Drug Safety Matters , a
0:45
podcast by Uppsala Monitoring Centre
0:48
, where we explore current issues
0:50
in pharmacovigilance and patient
0:52
safety . Joining
0:55
me today is Michele Fusaroli
0:57
, medical doctor and pharmacovigilance
0:59
scientist from the University of
1:01
Bologna in Italy . Michele
1:07
is fascinated by the area of research where medicine
1:09
and behavioural science overlap , so it's no
1:11
surprise that he chose to focus his PhD
1:14
studies on behavioural effects
1:16
of drugs and specifically
1:18
on impulsivity . He
1:21
is currently visiting UMC for a research
1:23
collaboration and
1:26
as he's also a big fan of this podcast , I just had to
1:28
invite him to the studio for a chat . He
1:32
explained how impulsivity
1:34
manifests , which drugs
1:36
cause it , how to cope with
1:38
it, and much more . I
1:41
hope you enjoy listening . Hi
1:53
, Michele , and welcome to Drug Safety
1:55
Matters . I'm
2:03
really glad you could make time for this interview and come here to talk about your research
2:05
and behavioural side effects of drugs . How are you feeling
2:07
today ?
2:08
I'm really good , I'm really excited because
2:10
of the opportunity to talk with you and
2:13
with the listeners of Drug Safety
2:15
Matters about my research . This
2:17
podcast has been always invaluable
2:19
to me because of how it allows
2:21
you to access other workers'
2:24
perspective ,
2:29
and I believe experiences like Drug Safety Matters are vital for fostering collaboration
2:31
and allow us to advance pharmacovigilance
2:34
together .
2:34
What an endorsement . Well , I'm really glad
2:37
to hear that you found the podcast
2:39
useful and
2:41
I hope listeners will find that
2:43
these episodes spark
2:45
ideas for collaboration . So,
2:48
let's get right into it
2:50
. I'm really looking forward to learning
2:52
more about behavioural side
2:54
effects , because I have the feeling
2:56
it's a topic that's not discussed
2:58
nearly enough . Even
3:00
in everyday life, right, as patients taking
3:03
medicines , we tend to think more
3:05
about how medicines affect our
3:07
body , and not so much our
3:09
mind and behaviour . So,
3:12
why is that ? Why is
3:14
there so little talk about such
3:16
side effects ?
3:18
I believe we are still entrenched into
3:20
Descartes' body-mind dualism .
3:27
Descartes was a 17th century French philosopher and scientist that theorised that the body
3:30
and the mind are two separate entities
3:32
. This way of thinking has two
3:34
effects that make behavioural
3:36
side effects some sort of invisible: under-reporting
3:40
and under-acknowledgement . First
3:42
, we , as patients , under-report
3:45
behavioural side effects due to our reluctance
3:47
to acknowledge that organic
3:49
conditions and exposure to substances
3:52
may influence our
3:54
behaviours , our thoughts , our choices
3:57
– those components of what
3:59
we define as our identity . Imagine
4:01
, after taking a medication for
4:03
Parkinson's disease , for example , we
4:06
perform an action that we would normally
4:08
not perform , that even feels
4:10
strange to us . For example , we enter
4:12
into a car shop and we spend
4:14
all our money in buying an extremely
4:17
expensive car . Well , in
4:19
this situation , we may not
4:21
report these strange
4:23
things that happen to us just because we
4:26
fear judgment , because we
4:28
feel responsible . Second
4:30
, we , as healthcare practitioners
4:32
, under-acknowledge behavioural
4:35
side effects because medical
4:37
education taught us to diagnose
4:39
and treat only organic conditions
4:42
, up to the point that psychosocial conditions
4:44
are of interest to us only
4:46
if they have a tangible and measurable substrate
4:49
. Even mild physiological drug effects
4:51
, like a small increase in blood pressure
4:53
, are more readily acknowledged than severe
4:56
behavioural changes . For example
4:58
, our patient may take a drug for
5:00
schizophrenia and just
5:02
after that, they may develop aggressivity
5:04
. In this situation, just because
5:07
we were
5:13
taught to do that, we may hurriedly think that schizophrenia may be enough to
5:15
explain this anger , to explain this episode , and maybe we
5:17
are not even thinking about a potential
5:19
role of the medication . To
5:21
sum up , the reason for so little
5:23
talk of behavioural side effects
5:26
is that there are both under-reporting
5:28
and under-acknowledgement .
5:30
And we'll try to dissect those
5:33
elements a little more in the
5:35
rest of the interview . We
5:38
advertised , as usual , the interview
5:40
on our social media channels , and
5:43
one of our listeners cited
5:45
an example of how drugs can affect
5:47
cognition . She cited
5:50
tamoxifen , which is a drug normally
5:52
used to treat breast cancer , and
5:54
how it can , on occasion , induce
5:56
brain fog . Have you heard about
5:59
that reaction ?
6:00
Indeed , there is evidence that tamoxifen
6:03
may be toxic for neural
6:05
cells and therefore may result
6:07
in a loss of focus and
6:09
even in memory impairment . Another
6:11
well-established effect of drugs on cognition
6:14
and behaviour is that of irritability
6:17
and aggressivity associated with
6:19
chronic use of corticosteroids . Well
6:21
, all drugs have adverse drug
6:23
reactions , and still we need their
6:26
beneficial effect , at least as long
6:28
as the underlying disease is worse than
6:30
the side effects themselves .
6:32
Absolutely . It's always about weighing the
6:34
benefits against the risks . But
6:36
you're more of an expert on behaviour
6:39
rather than cognition , as far as I understand
6:41
, and you specialise in
6:43
a particular kind of behavioural side
6:45
effects known as drug-induced
6:48
impulse control disorders . Now
6:50
, I know that may sound like a mouthful for our
6:52
listeners , but don't worry , we will explain
6:55
what they are . Let's start with
6:57
the basics , then . How do these disorders
6:59
manifest ?
7:01
If you have a drug-induced impulse control disorder
7:03
, it means that you have a difficulty
7:06
in resisting the urges or
7:08
temptation to behave in a certain
7:10
way , and this in turn affects
7:12
your well-being and may even harm
7:14
people around you . Four main
7:17
manifestations , termed as the
7:19
'four knights' of impulsivity , have
7:21
an apocalyptic effect on the quality of
7:24
life of patients and their families
7:26
. They are drug-induced pathological
7:28
gambling , hypersexuality
7:30
, compulsive shopping, and overeating
7:33
. However , impulse control disorders
7:35
vary widely and they
7:37
can take any form in the spectrum
7:39
of human behaviours , and they
7:42
usually align with the cultural
7:44
roles , social roles, and even life
7:47
experiences of the patient
7:49
. For instance , historically
7:51
, hypersexuality has been more prevalent
7:54
among men and compulsive shopping among
7:56
women, and these conditions are
7:58
distributed nowadays a bit more equally
8:01
, and this also reflects a change
8:03
in our society and in our culture
8:05
. In some Islamic countries , impulsivity
8:08
may affect some otherwise
8:10
completely normal religious behaviours , such
8:12
as resulting in excessive charity
8:15
or compulsive reading of the
8:17
Quran , even many hours per
8:19
day . Another example is
8:21
that of individuals with administrative
8:23
jobs , who may compulsively
8:26
organise documents , for example , and there are
8:28
also case reports in the literature
8:30
that describe some patients writing
8:32
poems or love
8:34
letters up to 12 hours per
8:36
day .
8:37
So I guess the manifestation varies
8:39
depending on who you are and what you normally
8:42
like to do or what kind of activities
8:44
you're drawn to .
8:45
Exactly .
8:46
What drugs are more likely to cause
8:49
these types of disorders , and is
8:51
it known why ?
8:53
There are two drug classes with an established
8:55
role in increasing impulsivity:
8:57
dopamine agonists , which are used in
8:59
Parkinson's disease , restless leg syndrome,
9:02
and prolactinoma; and third-
9:04
generation antipsychotics, used in
9:06
psychosis and mood disorder . The
9:08
exact mechanism , in fact , is
9:10
still underdefined . We
9:13
know that these drugs can directly enhance
9:15
dopaminergic activity in the nucleus
9:17
accumbens , that is , a region
9:19
of the brain involved in both
9:22
physiological motivation and pathologic
9:24
addiction . We also know that they may
9:27
switch off a serotonergic pathway
9:29
that normally modulates dopamine
9:31
levels in the nucleus accumbens . Given
9:34
these mechanisms' speculations
9:36
, we may also imagine that antidepressants
9:40
and psychostimulants in other situations
9:42
, in other conditions , may have
9:45
an effect on impulsivity . Anyways
9:47
, as always in science , there
9:49
are plausibly multiple mechanisms at
9:51
work , and we still have much
9:54
research to do in front of us to
9:56
really understand them .
9:58
What about frequency ? So, how
10:00
often do these side effects
10:02
manifest with these drugs ?
10:07
Exact frequencies are unknown . This is also because of
10:09
lack of a clear definition
10:11
of when impulsivity
10:13
becomes a disorder and also
10:15
because there is an extremely heterogeneous
10:17
time to onset . We can have
10:19
impulsivity days
10:21
or months or even years
10:24
after the first administration of the
10:26
medication . For this reason
10:28
, estimates range from 2 to
10:30
60% in different study
10:33
designs with different impulsivity
10:35
definitions . A plausible estimate
10:37
is that around 50% of patients
10:39
taking dopamine agonists develop
10:41
impulse control disorders within
10:44
five years . For
10:49
third-generation antipsychotics instead , the frequency
10:52
is even less clear . There is some idea , some evidence that supports
10:54
an even higher risk relative to dopamine
10:56
agonists , but these may also
10:58
be distorted by the fact that it
11:00
seems that third-generation antipsychotics may
11:02
cause impulsivity in just
11:05
days or weeks .
11:07
Are there any risk factors that can predispose
11:10
a patient to such disorders
11:12
?
11:13
Yes , there are . The main risk factors
11:15
are pre-existing depression and
11:17
impulsivity traits, for example,
11:19
if someone has novelty-seeking
11:22
personality , or it
11:24
is more common for males , for young
11:26
people, or for people
11:28
that had a history of
11:30
alcoholism , of smoking,
11:32
or even excessive coffee consumption
11:34
. Other possible risk factors
11:37
for impulsivity are higher
11:39
doses of dopamine agonists and
11:42
also certain genetic factors may
11:44
play a role .
11:45
From everything you've said, it can't be
11:47
easy to live with an impulse control
11:50
disorder , and you've mentioned a few examples
11:52
, but can you help us understand exactly
11:55
how patients are impacted . Like,
11:57
to what extent do these disorders
12:00
affect quality of life ?
12:02
The impact of impulse control disorders varies
12:05
greatly depending on their expression
12:07
and severity . Mind that the impact
12:10
of impulsivity may not
12:12
always be negative , it may also
12:14
be positive . In fact , individuals
12:16
with Parkinson's disease usually have
12:18
lower levels of dopamine in
12:20
the nucleus accumbens and therefore
12:22
also lower motivation . And
12:25
when they start getting dopamine agonists
12:27
we sort of normalise
12:29
their dopamine levels in the nucleus
12:31
accumbens , we boost motivation
12:34
and creativity . And what
12:36
the patients experience in the first months
12:38
of dopamine agonist treatment is
12:40
an actual honeymoon period in
12:42
which they start again getting involved
12:45
in activities , in which they even
12:47
develop new hobbies . However
12:49
, problems arise when impulsivity
12:51
gets out of control . In
12:53
this situation , the
12:56
pathologic behaviours consume
12:58
the entire life of the individual and
13:00
it can have a serious impact on the
13:02
financial stability , on the social relationships
13:05
, on the employment of the individual
13:07
. It can even cause legal issues . Moreover
13:10
, there are also expressions that are more
13:12
specific to the behaviour . Pathological
13:14
gambling and compulsive shopping , for example
13:17
, result more often in higher
13:19
loss of money and therefore can
13:21
have more problem in financial stability
13:24
and in the social relationships
13:26
. Hypersexuality, instead
13:28
, is usually associated with marital
13:30
problems , with sexually transmitted
13:32
diseases , depending on the age
13:34
also in unintended pregnancy
13:37
and sexual dysfunction . Overeating
13:39
instead can lead to obesity , metabolic
13:42
syndrome , sleep apnoea . And we
13:44
don't have to think that other behaviours
13:47
that are not among these four have
13:49
no impact on the quality of life . For example , even
13:51
a seemingly harmless compulsive
13:54
gardening may cause excessive
13:57
expenditure of money and may
13:59
result in the patient staying outside in
14:01
the garden and doing work , even
14:03
during a storm , for example , with serious
14:06
danger for their life .
14:07
Exactly . So, quite serious consequences
14:10
, even though they may sound as harmless
14:12
behaviours to begin with . Something
14:14
to keep in mind . Let's
14:17
move on to the diagnosis now , which
14:19
I imagine must be really
14:21
challenging , not least because
14:24
of what you said earlier , that it
14:26
can be really difficult to distinguish
14:28
compulsive actions from normal
14:30
ones . I mean, behaviour , even
14:32
in a normal situation, occurs on a spectrum
14:35
, so how do you tell what's normal
14:37
from pathological ? So, if
14:39
we go back in time
14:41
, can you tell me how these disorders were
14:44
identified in the first place ?
14:46
I think the first time was in 2003
14:49
, when Driver- Dunckley and colleagues from
14:51
the Barrow Neurological Institute in Phoenix
14:53
published a study , a case
14:55
series , with nine cases
14:58
of pathological gambling that
15:00
developed after taking dopamine agonists
15:02
. What raised a concern and
15:04
a suspicion of adverse drug reaction
15:07
was not the time to onset , because
15:09
the average was around 20
15:11
months . It wasn't even the frequency
15:13
, because it wasn't really significantly
15:16
higher than what expected based on the entire
15:18
population . What raised
15:20
a concern was the
15:23
seriousness of the event . These
15:25
patients started gambling without
15:28
any control . They started losing more
15:30
and more money and even one
15:32
patient committed suicide after
15:34
an extremely severe episode of gambling
15:41
. Interestingly , reducing the dose or switching to alternative
15:43
medication showed promise in mitigating this condition and also
15:45
, as we said before , subsequent
15:48
research highlighted that there
15:50
is an extreme difference between the low
15:52
motivational drive that is implicit
15:55
in Parkinson's disease and
15:57
the extreme motivational drive that we observe
15:59
when patients take dopamine agonists
16:01
.
16:03
And what about the
16:06
other class of drugs you mentioned at
16:08
the beginning , so these third- generation
16:10
antipsychotics ? Was it even
16:12
trickier to associate abnormal
16:15
behaviours to those types of drugs
16:17
, since they are used in conditions
16:20
like psychosis or bipolar
16:22
disorder that are already marked
16:25
by impulsivity ? How did it work
16:27
out for those drugs ?
16:29
Yeah , it was more challenging . In
16:31
fact , third-generation antipsychotics- induced
16:33
impulsivity may be considered that
16:36
sort of 'black swan' that
16:38
François Montastruc spoke about in
16:40
the last episode: therefore , an event
16:42
, a reaction that is completely
16:45
unexpected and also particularly
16:48
serious . Healthcare providers
16:50
initially blamed the disease and
16:53
not the drug . For example , they attributed
16:55
the impulsivity episode to schizophrenia
16:57
or to a bipolar disease
16:59
. Consequently , when in 2014
17:03
a disproportionality analysis on the FDA
17:05
adverse event reporting system found
17:08
a signal of potential
17:10
adverse drug reaction between aripiprazole and
17:13
impulse control disorders , most
17:16
of the reports were from patients , not
17:18
from doctors . Doctors
17:20
, in fact , started to report only
17:22
after 2016
17:24
, when an FDA warning came out . The
17:27
key factor aiding in the detection
17:30
of this signal was the
17:32
patient's experience , just a few
17:34
days after taking the first
17:36
dose of aripiprazole , of
17:38
an extreme loss of
17:40
control . Also , behaviours
17:43
that they may have shown before the
17:45
first administration of the drug, for example , they
17:48
are patients that may be more susceptible
17:50
to gambling and to compulsive
17:52
shopping and hypersexuality because of the
17:54
underlying disease, started
17:56
spiralling down and
17:59
they completely resolved
18:01
after the discontinuation of the drug
18:03
. I think that
18:05
the journey of discovery of impulse control
18:08
disorders induced by third- generation
18:10
antipsychotics has an important
18:12
message for us . That is to
18:14
listen to the patients . Patients
18:17
should be acknowledged as the main expert
18:19
of their disease , of their experience
18:22
of disease , and they should
18:24
be actively involved
18:26
as primary
18:28
stakeholders in clinical
18:30
practice , but also in signal detection
18:33
and signal refinement .
18:35
And that message truly resonates with us
18:37
. We have at least two
18:39
episodes in the archives on patient
18:42
engagement and patient
18:44
voices in pharmacovigilance , but
18:46
you raise so many important points . It's
18:48
also so fascinating to hear what
18:50
sparks that initial
18:52
suspicion . I think that's what makes the
18:55
job of pharmacovigilance professionals so
18:57
interesting . So,
19:00
we've looked at the past and how
19:02
these conditions were first
19:04
identified . Back to
19:06
present day: so, how are
19:09
drug-induced impulse control
19:11
disorders diagnosed
19:13
nowadays ?
19:15
If you listen to the recent episode on drug-induced
19:18
liver injury by Rita Baião
19:20
, you know that diagnosis
19:22
in medicine is usually based on
19:24
well-defined diagnostic criteria , and
19:27
the problem here is that we really
19:29
don't have those diagnostic criteria . There
19:32
are some scales that can
19:34
be used to diagnose and stage
19:36
impulsivity in Parkinson's disease
19:38
, like QUIP and Ardouin
19:41
, but they have
19:43
extremely well-recognised limitations
19:45
. For example , they consider only a
19:48
few possible behaviours
19:50
as manifestation . They don't include , for example
19:52
, kleptomania that may be one
19:54
of the manifestations of drug-induced impulsivity
19:57
. Timely diagnosis should
19:59
therefore rely on two
20:01
main factors . The first is
20:03
education of patients
20:06
and their caregivers on what
20:08
is the risk of impulse control disorder
20:10
, how they manifest, and even
20:12
their impact on quality of life . Second
20:15
, a timely diagnosis also
20:17
has to rely on frequent interviews
20:20
with both the patient and the caregiver
20:22
, because the patient may
20:24
sometimes be shy
20:26
or even reluctant to
20:28
report something because
20:30
they feel ashamed .
20:32
Of course . So that's a really important message
20:34
for patients , their carers, and
20:36
healthcare professionals . Be vigilant and
20:39
raise an alarm if you have
20:41
a suspicion that there might be something at
20:43
play here . We've talked about
20:46
then the diagnosis , complicated as
20:48
it may be . Once that has been
20:50
made , what strategies
20:52
can doctors or patients
20:54
themselves adopt to deal
20:56
with such behaviours and potentially
20:59
counteract them ?
21:01
As soon as there is an even mild impairment
21:03
of the biopsychosocial function
21:05
of the patient or the caregivers
21:07
, that is the time when
21:10
an intervention is needed, before
21:12
any severe or even irreversible
21:15
deterioration of quality of life happens
21:17
, such as those related with loss
21:19
of employment , divorce, or
21:22
legal issues . There isn't abundant
21:24
evidence on how to manage these conditions
21:27
. Here at UMC , I am
21:29
using individual case safety reports
21:31
to try to map how people
21:34
are already managing these
21:36
reactions in the real world , to
21:38
identify some pitfalls and some
21:40
good practices . Discontinuing
21:42
the drug may suffice for third-generation
21:45
antipsychotics . For dopamine
21:47
agonists it is more challenging . A
21:50
year after discontinuation , still
21:52
50% of the patients hasn't
21:54
resolved . A consensus
21:57
group for managing impulsivity in Parkinson's
21:59
disorders recently published
22:01
an expert opinion-based guideline . They
22:04
recognize the pivotal role of
22:06
involved caregivers and of
22:08
psychosocial interventions . For
22:10
example , for pathological gambling and compulsive
22:12
shopping , it may be extremely useful to
22:14
restrict access to credit cards and
22:17
to casinos and shops . For
22:19
example, it can also be useful to restrict access
22:21
to the internet , since many
22:24
of these behaviours are enacted
22:26
also online today , both gambling
22:28
, compulsive shopping , hypersexuality,
22:30
and so on . Sometimes
22:32
it may also be necessary to seek legal
22:34
support or even social support
22:36
. Concerning the pharmaceutical
22:39
management instead , these experts
22:41
could only agree on the need for closely
22:43
monitoring and tapering down dopamine
22:46
agonists at the first sign of
22:48
impairment . In fact , cautiously
22:50
, because there are some risks of
22:52
withdrawal syndrome , of
22:54
a long-term apathy and
22:56
of worsening of the motor symptoms
22:59
of Parkinson's disease itself as
23:01
soon as we discontinue the
23:03
drug . When this is
23:05
not sufficient , then the management
23:07
relies more on trial and error . There
23:09
are some strategies that received
23:12
more than 50% agreement
23:14
in this expert opinion . That is still low
23:17
as an agreement , but they
23:19
are , for example , cognitive behavioural
23:21
therapy, they are quetiapine
23:24
, clozapine, or even deep brain
23:26
stimulation that consists in surgically
23:29
placing some electrodes
23:31
in the brain to modulate its activity
23:33
.
23:34
So, it is complicated , but there are
23:36
ways to alleviate these
23:39
conditions and I
23:41
guess the general advice, as with any side
23:43
effect, just never stop taking
23:45
the drug unless you consult your physician,
23:48
right ? There's a reason why you've been put on it in
23:50
the first place . Back
23:52
to our social media
23:54
questions . We have another query
23:57
that came in from one of our listeners . Sudarshan
24:00
in India asked something
24:02
that is related to one of
24:04
the projects you are working on here
24:06
at UMC . He asks, how
24:09
does pharmacovigilance work
24:11
in these complicated scenarios
24:14
? As we've said , it's not always easy
24:16
to differentiate the adverse
24:18
event from the underlying disease
24:20
. So, can you tell us , as
24:23
a pharmacovigilance professional , how do you
24:25
think when approaching both
24:27
the identification but also the assessment
24:30
of reports in these conditions ?
24:33
At the UMC , I am now investigating methylphenidate-related
24:36
impulsivity . Methylphenidate
24:39
is a psychostimulant drug that is used
24:41
in ADHD to treat inattention
24:43
and impulsivity , but its effects
24:46
seem to be dependent on the baseline condition
24:49
, for example , of neurotransmitter of
24:51
the patient . There is some
24:53
evidence that, in some cases
24:55
, methylphenidate may aggravate or
24:57
even cause impulsivity , and
25:00
this is a 'black swan' , even more than antipsychotics
25:02
. A drug used to treat a condition
25:04
that , in certain situations , may
25:06
cause it . How to deal with
25:08
such a difficult situation ? Well , the first
25:11
thing we need to do is
25:13
to make sure that the reports we are
25:15
looking at are actually of a suspected
25:17
adverse drug reaction . We may also
25:19
have , sometimes , a report , for example
25:22
, of inefficacy: that is
25:24
, the drug was taken to treat
25:26
impulsivity but it
25:29
didn't work and therefore impulsivity is still
25:31
there . Another report that we may
25:33
observe is a resurgence of
25:35
impulsivity because of a drug shortage
25:37
. Therefore , like in the apothecary
25:39
there wasn't any more methylphenidate
25:42
, the patient stopped
25:44
to take it and impulsivity came back
25:46
. And narratives , when available
25:48
, are extremely useful to
25:51
differentiate between these different kinds
25:53
of reports . When we have identified
25:56
reports of suspected methylphenidate-induced
25:59
impulsivity , then we
26:01
can apply the usual causal indicators
26:03
that we use in causality
26:06
assessment . For example , we can look
26:08
into the temporal relationship , into
26:10
the exclusion of alternative causes . Yes
26:13
, we know that there is always ADHD
26:15
there as an underlying possible
26:17
cause . We can look at the relation
26:19
with the dose , at the challenge
26:21
and re-challenge . So, what happened when we stopped
26:23
the drug and we administered again
26:25
the drug ? And , particularly
26:28
important , as we have learned
26:30
from the case of impulse control disorder
26:33
, we can also look into the
26:35
experience of the patient, that
26:37
something happened , that something is different
26:39
from before .
26:46
This is such a complicated topic . I think we've described so many aspects of
26:48
it as challenging and difficult to approach . So, if you were
26:50
to wrap up on an encouraging note
26:53
, what would you say to patients
26:55
who are dealing with such difficult
26:57
conditions , or to healthcare
26:59
and pharmacovigilance staff who are trying
27:01
to help those patients ?
27:04
I often draw parallels between drug-induced
27:06
impulse control disorders and
27:08
Herman Melville's "Moby Dick"
27:10
. At first , the great white whale
27:12
serves as a driving force , even
27:15
a purpose , for Captain Ahab . It
27:17
is something positive that gives meaning
27:19
to their life . Yet it
27:21
evolves into an overwhelming obsession
27:23
, a compulsion that ultimately
27:25
drags Ahab into the depths of
27:27
the sea . Similarly , impulsivity
27:29
may start innocently and may
27:31
even be positive , as we said for the
27:34
honeymoon period in Parkinson's
27:36
disease , but it can also escalate
27:38
into a serious issue . Recognising
27:46
when we are losing control and seeking help is therefore crucial . We have to remember that
27:48
a diagnosis is not a conviction
27:50
. It is not a
27:53
stigmatising label . A
28:00
diagnosis is instead a tool to identify and address some needs that we have . To regain control
28:02
, we must lean on the people that surround us
28:04
. Caregiver involvement is still
28:06
the best predictor of recovery
28:09
from dopamine agonist-induced impulsivity
28:11
. The message is that we
28:13
don't have to face these battles alone . By
28:21
relying on our loved ones , we can receive the treatment that we actually need while keeping control
28:23
of our impulses . We can together navigate
28:25
the depths while keeping our vessel
28:27
steady and avoid being dragged into the
28:29
abyss by our own personal
28:32
white whale .
28:33
And I think we'll end on that encouraging note
28:35
. Don't be afraid to speak up . If
28:37
you have a suspicion that something's wrong
28:39
, do talk with your loved ones or
28:42
your healthcare professional . Well
28:44
, thank you very much for taking the time to
28:46
come on the show . Thanks . That's
29:07
all for now , but we'll be back soon with more conversations on medicines safety . If you'd like
