Welcome to the seventh season of the Dementia Researcher X ISTAART PIA Relay Podcast. Across six episodes, leading early career and senior researchers hand the mic from one ISTAART PIA to the next, giving you an honest, peer-to-peer tour of where dementia research is actually heading, from wearables and biomarkers to policy and trial design, in the run-up to AAIC.
Lewy body pathology shows up in roughly 30% of the brains of people who had dementia, yet it gets diagnosed in only about 5% of cases. Closing that gap has shaped much of Dr Joe Kane's career. Joe is a geriatric psychiatrist at Queen's University Belfast and outgoing Chair of the ISTAART Lewy Body Dementias PIA, and with host Dr Patrick Lao he traces his work from the Diamond Lewy programme to consensus diagnostic guidelines built by Delphi process. They discuss the symptoms clinicians often miss because they don't think to ask, from constipation to loss of smell, the cardiac scans and seed amplification assays now detecting pathology in CSF and even skin, and the TOP HAT trial repurposing an anti-sickness drug for hallucinations. Joe makes the case for a Lewy body specific rating scale, explains why the prodrome may be psychiatric or delirium rather than cognitive, and runs through the PIA's biggest AAIC programme in years, including a PIA Day panel on seed amplification assays.

Speaker:- [Voice Over] Hello, and
welcome to season seven
Speaker:of the Dementia Researcher
ISTAART Relay podcast.
Speaker:In this series, members of the ISTAART's
Speaker:professional interest
areas interview each other
Speaker:about their PIAs and the
hot topics in their fields.
Speaker:Each guest then becomes
the next episode's host,
Speaker:passing the conversation along
Speaker:from one researcher to the next.
Speaker:We're releasing one episode a day
Speaker:in the run-up to the
Alzheimer's Association
Speaker:International Conference, this
year in London and online,
Speaker:showcasing the work of the ISTAART PIAs.
Speaker:Thank you for listening.
Speaker:(upbeat music)
Speaker:- Hi, and thanks for tuning in.
Speaker:I'm Patrick Lao, and I'm
an assistant professor
Speaker:at Columbia University, and
I work on the Down syndrome
Speaker:associated Alzheimer's disease
professional interest area.
Speaker:I'm the current programme chair
and the incoming vice chair.
Speaker:So today I'm excited
to be talking with Joe
Speaker:from the Lewy body dementia
professional interest area.
Speaker:So hi, Joe.
Speaker:Could we start with you
introducing yourself?
Speaker:- Sure.
Speaker:My name is Joe Kane.
Speaker:I'm a geriatric psychiatrist
and a researcher
Speaker:from Queen's University,
Belfast in Northern Ireland.
Speaker:And I am the chair of the PIA.
Speaker:I will be handing over the reins
Speaker:to your incoming chair,
Federico Rodriguez-Porcel
Speaker:at AAIC this summer.
Speaker:So it's been really exciting.
Speaker:It's been really fun, but
it's time to hand it over.
Speaker:- That's great.
Speaker:So before we talk about
your work with the PIA,
Speaker:could you tell us about your own work?
Speaker:- Sure.
Speaker:I've been working in Lewy body dementia
Speaker:for about 10 years.
Speaker:And one of the things about
working in this disease area
Speaker:is that you really do get to
experience the whole breadth
Speaker:of the topics that make
up Lewy body dementia.
Speaker:And you get to bring all
those strands together.
Speaker:So I started off with
a very clinical angle.
Speaker:I worked on a programme
called Diamond Lewy,
Speaker:which was a kind of multi-step programme
Speaker:to look at how Lewy body
dementia was diagnosed
Speaker:and treated within the UK
National Health Service.
Speaker:That was my introduction
to Lewy body dementia.
Speaker:And one of the things we did
Speaker:was we did a large epidemiological study
Speaker:of clinical diagnosis of LBD.
Speaker:Even though we see pathological evidence
Speaker:in about 20 to 30% of brains
of people with dementia,
Speaker:really it's diagnosed in what
we find was around about 5%.
Speaker:So we then kind of set out to try and see
Speaker:what we could do about that.
Speaker:We did, amongst other things,
Speaker:we developed a consensus
around how to best diagnose
Speaker:and treat Lewy body dementia.
Speaker:And we did a cluster-randomized trial
Speaker:where we introduced these toolkits,
Speaker:these consensus advice pieces
in the different services
Speaker:and saw if they helped people.
Speaker:And we did find that there
were some improvements
Speaker:in people's lives there.
Speaker:And then I complemented that
Speaker:with a bit of work with biomarkers.
Speaker:I used a scan, a cardiac scan,
Speaker:called MIPG, and we used
that to differentiate
Speaker:Lewy body dementia from
Alzheimer's disease.
Speaker:And that was pretty cool,
that was pretty exciting.
Speaker:And it's something I've
continued on as well,
Speaker:some of that type of work.
Speaker:And then once I returned to Belfast
Speaker:and returned to clinical work,
Speaker:I found myself doing a
lot of clinical trials.
Speaker:And that's what I've been
doing a lot of locally,
Speaker:as well as doing a bit of biomarker work
Speaker:and as well as doing the work with the PA.
Speaker:So I'm a local lead for
a few different trials
Speaker:in Lewy body dementia.
Speaker:I recruit patients from my clinic
Speaker:and both organise and collect the data.
Speaker:And it's really great because I get to see
Speaker:where research sits in the life cycle
Speaker:of someone coming into a service,
Speaker:understanding their diagnosis,
Speaker:maybe doing a bit of patient
public information work
Speaker:with us or advisory work with us,
Speaker:and then maybe coming into a trial.
Speaker:So it's great for me because
it's also clinically aligned.
Speaker:And although I can do, try
to work with scientists
Speaker:that really help develop my
understanding in other areas,
Speaker:I really find that the patient
and their care partners
Speaker:are at the middle of what I try to do.
Speaker:And what we see when we go
to conferences like this,
Speaker:like AIC, is that we benefit from people
Speaker:with loads of different expertise
Speaker:that maybe they brought from the likes
Speaker:of the Alzheimer's world,
Speaker:but maybe they've brought from
completely different places.
Speaker:We work closely with them to
try and develop new projects
Speaker:and new angles on this.
Speaker:So it's a really exciting field to be in.
Speaker:I've been very fortunate to work on it
Speaker:over the last 10 years
Speaker:and I'm really excited
to see how things develop
Speaker:in the future.
Speaker:- Yeah, that's great.
Speaker:That's an incredible range of
different types of studies,
Speaker:doing clinical to clinical work,
Speaker:to clinical trials and
epidemiological studies.
Speaker:So when you mentioned that
there was about 30% of brains,
Speaker:or was it 30% of individuals diagnosed
Speaker:with Lewy body dementia,
Speaker:but only 5% of them had
a pathology at autopsy?
Speaker:- So when we do autopsy studies
Speaker:of people with dementia,
Speaker:we find good going Lewy body pathology
Speaker:in about 30% of those brains.
Speaker:Now, in a good percentage of those brains,
Speaker:there's also a good amount of
Alzheimer's pathology there.
Speaker:And we know that Alzheimer's pathology
Speaker:interacts with Lewy body pathology
Speaker:and in different ways
Speaker:that we're only just really
starting to understand.
Speaker:But it's such a big jump
Speaker:from that huge proportion of people
Speaker:who have that pathology
Speaker:to the clinic whereby,
Speaker:5% in a Lewy body
dementia research clinic.
Speaker:You know, in other services,
Speaker:you know, there are some services
Speaker:that might not see people
with Lewy body dementia
Speaker:for months at a time.
Speaker:And our argument has always been
Speaker:that a big part of that is,
Speaker:yes, starting to co-morbid pathology
Speaker:and how it influences the
expression of that pathology,
Speaker:but also the fact that
there are symptoms there
Speaker:that not everybody is
accustomed to looking for.
Speaker:And, you know, these are symptoms
Speaker:like REM sleep behaviour disorder,
Speaker:in which someone acts out their dreams.
Speaker:And we keep telling people
Speaker:that if they're not comfortable
Speaker:asking about these symptoms,
Speaker:you won't detect it.
Speaker:And if you don't detect the symptoms,
Speaker:you're not gonna make the diagnosis.
Speaker:So we feel that even though the pathology
Speaker:is a big part of it,
Speaker:we feel that the detection
Speaker:is also a really significant part of it.
Speaker:So we need to approach it
from both angles, really.
Speaker:- And you mentioned that the
guidelines that you published,
Speaker:they helped, the clinical
guidelines that you published
Speaker:really helped sort of fix that gap.
Speaker:- Yeah, I mean, it's great
Speaker:when there's a huge body of evidence
Speaker:on which you can draw in a clinic
Speaker:and when you can rely on really good
Speaker:randomised control trial
data and, you know,
Speaker:phase four studies.
Speaker:But the reality is for a lot
of the less common dementias
Speaker:and for lots of different
conditions in general,
Speaker:you're relying on different study designs.
Speaker:You're relying on a little
bit of expert opinion.
Speaker:You're relying on some
anecdotal data as well.
Speaker:So that was where that came
about, how that came about.
Speaker:Rather than just do a systematic review
Speaker:and dredge the really,
really good quality,
Speaker:robust data there, we were able to go out
Speaker:into our Lewy body dementia community.
Speaker:We were able to gain
consensus through this process
Speaker:that we call a Delphi, where
everyone or a good proportion
Speaker:of people needs to agree
with a certain statement
Speaker:before it gets accepted
into the guidelines.
Speaker:And whilst it's not perfect by any means,
Speaker:and even just today, I
shared those guidelines
Speaker:with colleagues that were approaching me
Speaker:and asking me for advice.
Speaker:So yes, you can throw somebody
Speaker:a really good journal article
Speaker:which tells you about this
or tells you about that,
Speaker:but to be able to say to somebody,
Speaker:here are consensus guidelines
on how you should diagnose
Speaker:and treat this condition,
it's just so invaluable
Speaker:for busy clinical staff.
Speaker:So that's been really rewarding,
Speaker:and we're actually in the
process of updating those.
Speaker:- Oh, that's great.
Speaker:Yeah, and I think that's where biomarkers
Speaker:can really come in handy
if the clinical diagnosis
Speaker:is tricky.
Speaker:So you mentioned using
cardiac scans to differentiate
Speaker:between Lewy body disease
and Alzheimer's disease.
Speaker:Could you tell me more about that?
Speaker:- Sure, one of the things
that has always struck us
Speaker:about Lewy body dementia is that we see
Speaker:in the patient's symptoms
evidence of pathology,
Speaker:not just in the brain,
but throughout the body.
Speaker:A large proportion of people
with Parkinson's disease
Speaker:and a large proportion of people
Speaker:with Lewy body dementia will
not necessarily describe
Speaker:cognitive problems as their first problem.
Speaker:And what you see is a lot of constipation.
Speaker:You see a lot of autonomic dysfunction.
Speaker:And there is some good
autopsy data to suggest
Speaker:that in a fair proportion of people
Speaker:with Parkinson's disease and
other Lewy body diseases,
Speaker:that there is some degree of spread
Speaker:from lower down in the
peripheral nervous system
Speaker:up in eventually to the
central nervous system.
Speaker:So the idea behind the cardiac scans
Speaker:is that we leverage that
fundamental difference
Speaker:between Lewy body dementia
and Alzheimer's disease
Speaker:and try to identify pathology
Speaker:in the peripheral nervous system.
Speaker:And theoretically as well,
Speaker:doing that at a very early stage.
Speaker:And the cool thing
about this scan is that,
Speaker:you know, in Japan, for example,
Speaker:nearly everybody suspected
of having Lewy body dementia
Speaker:gets this as one of their first scans.
Speaker:So there's really good data out there.
Speaker:And what we did back in my PhD work
Speaker:was we compared this cardiac scan,
Speaker:which demonstrates adrenergic dysfunction.
Speaker:Due to Lewy body pathology.
Speaker:And we compared that with
the other famous biomarker
Speaker:we have, which is the dopamine DAT scan.
Speaker:So which does look at the
dopamine uptake in the striatum.
Speaker:And we find that even though
it was very good biomarker
Speaker:in the UK population,
Speaker:wasn't quite as effective as the DAT scan.
Speaker:But there's been a lot that has changed
Speaker:in the Lewy body dementia
sphere since then.
Speaker:And that we're now looking at disease
Speaker:earlier and earlier and earlier.
Speaker:What we are starting to think
of is these cardiac scans
Speaker:and these DAT scans, dopamine scans,
Speaker:as being complementary rather
than head-to-head biomarkers.
Speaker:And we also think that, you know,
Speaker:certain phenotypes may demonstrate
Speaker:that the biomarker may be more effective
Speaker:in certain phenotypes.
Speaker:So it's still very much there.
Speaker:It's still part of our
diagnostic criteria.
Speaker:It's something that we're
learning a bit more about,
Speaker:but it's always been a cool angle.
Speaker:I find that not only
researchers and clinicians,
Speaker:but patients really buy into that
Speaker:because they, as soon as they hear that
Speaker:constipation is a symptom
or urinary incontinence
Speaker:or heat or cold intolerance is a symptom,
Speaker:they will inevitably say,
"Oh yeah, I had that.
Speaker:"I've had that for a few years."
Speaker:And it's crazy once you start going
Speaker:and systematically asking
people about their bowels
Speaker:or systematically asking them
about their sense of smell.
Speaker:There's a huge proportion of older people
Speaker:that are affected by that.
Speaker:While they're not
necessarily the best means
Speaker:of discriminating Lewy body dementia
Speaker:from Alzheimer's disease,
Speaker:it does show us that there's different
Speaker:pathological processes,
Speaker:and we need to somehow leverage those.
Speaker:- Yeah, I've heard about some
alphabetically in biomarkers,
Speaker:maybe some PET tracers
at an early development,
Speaker:as well as the seed amplification assay.
Speaker:And that seems to only
work in CSF right now,
Speaker:but not necessarily plasma.
Speaker:How would those change the field?
Speaker:- Well, the seed amplification assays
Speaker:have really sparked so
much interest in the field.
Speaker:They have been really useful in CSF, and
Speaker:the USDLB Consortium and
some of our colleagues
Speaker:in the likes of
Newcastle-upon-Tyne and Amsterdam,
Speaker:they've really lent into the CSF analysis.
Speaker:But what's also interesting
is that you can use
Speaker:the seed amplification
assays on other tissues.
Speaker:My understanding is that in
blood it's quite difficult
Speaker:because it's quite easy
to get false positives
Speaker:because of the clumping together.
Speaker:But what a lot of my
colleagues in the States
Speaker:have been using, and something
that we're really looking
Speaker:forward to talking about on our PA day,
Speaker:is the use of skin biopsy.
Speaker:So with a very small
punch biopsy in the skin,
Speaker:we can put them into these
seed amplification assays.
Speaker:For those that don't understand,
Speaker:it's basically a mechanism of growing
Speaker:the alpha-signed eukaryotic fibrils
Speaker:until they're detectable.
Speaker:And even in very, very small
quantities in the skin,
Speaker:they can be grown and detected,
Speaker:and they can indicate
that there's evidence
Speaker:of this pathology.
Speaker:And you're right, although
there is promising data
Speaker:around markers that we
can use in neuroimaging,
Speaker:those aren't scalable yet,
they have their issues.
Speaker:The idea of a skin
biomarker or a CSF biomarker
Speaker:is just so much more
seemingly within reach
Speaker:to clinical practise, and it's
something we're finding out
Speaker:more and more data about.
Speaker:And until we get that
really good PET tracer
Speaker:that's really stable and really scalable,
Speaker:I think we're gonna continue
looking into this evidence
Speaker:of pathology through places like the skin,
Speaker:but also CSF and elsewhere.
Speaker:- And you mentioned with clinical trials,
Speaker:what are the targets for those?
Speaker:- And there's different targets for them.
Speaker:They're not necessarily the places
Speaker:where you expect to look for.
Speaker:So one of the trials that we're looking at
Speaker:led by University College London
Speaker:is called the TOPHAT trial.
Speaker:So it's using ondansetron,
which is a very widespread use
Speaker:as a anti-sickness, anti-emetic drug
Speaker:in cancer and oncology
practise in particular.
Speaker:Although we have long thought
of the Lewy body dementia
Speaker:as a disruption of dopaminergic systems,
Speaker:and then later on, cholinergic systems,
Speaker:and the likes of the use of ondansetron,
Speaker:it's actually serotonergic.
Speaker:So it's looking at the upstream effects
Speaker:of the dopamine degradation
Speaker:that causes hallucinations that we see
Speaker:in Parkinson's disease
and Lewy body dementia.
Speaker:So in some of the other studies,
Speaker:they're looking at
different targets as well.
Speaker:And it's a really exciting time
Speaker:in Lewy body dementia research
Speaker:because these targets are emerging
Speaker:and because they are quite diverse.
Speaker:And that's before we even get to that idea
Speaker:that we hope is coming
later on down the line
Speaker:of somehow modifying that
Alzheimer's pathology
Speaker:in people with Lewy body pathology.
Speaker:So range of targets, all it
takes is one of them to work
Speaker:for it to transform the field,
Speaker:but there's certainly
plenty in the pipeline
Speaker:and plenty of cause for
optimism as a consequence.
Speaker:- Yeah, that's great to hear,
Speaker:especially because you mentioned
Speaker:the different clinical subtypes
Speaker:and so there might be different strategies
Speaker:for different groups.
Speaker:- It's no secret in
Parkinson's in particular,
Speaker:there's different clinical phenotypes
Speaker:represent very different symptom groups,
Speaker:prognoses and different
responses to medication.
Speaker:We're fairly confident
it's gonna be the same
Speaker:in Lewy body dementia,
Speaker:but we need the big sample sizes
Speaker:and the big studies to do that.
Speaker:- Great, so thinking more broadly,
Speaker:are there any emerging topics at the field
Speaker:that you wanna highlight?
Speaker:- Sure, I mean, the real thing
that's on everyone's lips
Speaker:from my perspective is the trials
Speaker:and because so many of us
are working in clinics,
Speaker:we're working closely with participants,
Speaker:working closely with
advocacy groups and charities
Speaker:and it just totally
transforms the conversation
Speaker:when you can talk about
interventional trials
Speaker:and not just observational ones.
Speaker:Obviously, we've still got a lot to learn
Speaker:from observational trials,
Speaker:but it really transforms
the dynamic in the clinic
Speaker:when you talk about,
Speaker:there are new treatments on that,
Speaker:that might be on the horizon,
Speaker:do you want to be a part of that?
Speaker:The thing is with the trials
becoming more and more
Speaker:of an issue is that they
really made us reflect
Speaker:on the trial environment
and their trial design.
Speaker:One of the things that
PEA has done really well
Speaker:has been to examine trial design.
Speaker:So we've always relied
very heavily on things
Speaker:like outcome measures for
things like Parkinson's,
Speaker:for things like Alzheimer's disease.
Speaker:We use the likes of the CDR, for example,
Speaker:that are designed for Alzheimer's disease
Speaker:and don't always necessarily
reflect the experience
Speaker:of the patient.
Speaker:And we were also
conscious that some trials
Speaker:might be failing because
their outcome measures
Speaker:aren't specific to Lewy body dementia.
Speaker:So it's really made us think
very hard about trial design.
Speaker:It's made us think about
how we leverage biomarkers
Speaker:in trial design,
Speaker:how we look towards the start
Speaker:of kind of stratified medicine process
Speaker:of maybe using some of
the Alzheimer's biomarkers
Speaker:to work out when someone's
got mixed pathology.
Speaker:And the other thing that
we really identified
Speaker:as a very significant need has been a DLB
Speaker:or Lewy body dementia
specific rating scale.
Speaker:And that's what we've been working on
Speaker:over the past few years.
Speaker:I'll be presenting at AAIC
some of our work with that.
Speaker:It's been really exciting
because it's allowed us
Speaker:to engage the Lewy body
dementia community.
Speaker:All of us working together
on this one question
Speaker:with many kind of sub questions to it.
Speaker:And we've made really good progress
Speaker:but we do have some way to go.
Speaker:So that's been something which has really
Speaker:captured people's
imagination in the field.
Speaker:And I think it's brought
us together as a community.
Speaker:And we're hopeful that if
we develop the right tool
Speaker:that it will actually catalyse trials
Speaker:and encourage some of these novel targets
Speaker:to be investigated.
Speaker:And for the regulatory authorities,
Speaker:people like the FDA, for example,
Speaker:to buy in to these treatments
Speaker:if they do appear to be effective.
Speaker:So obviously I'm biassed
because it's something
Speaker:I've been working very heavily in
Speaker:but I do think that's
generated a lot of interest.
Speaker:- Yeah, totally agree.
Speaker:When you can start talking
about interventions
Speaker:to patients and participants,
Speaker:it really changes the entire conversation.
Speaker:So that's been really
helpful to set the scene
Speaker:for what I wanna talk about next,
Speaker:which is the work of your PIA.
Speaker:So you mentioned a little bit
Speaker:of how you've been reevaluating
Speaker:the design of clinical trials.
Speaker:But are there some other examples
Speaker:of how the work of your
PIA supports research?
Speaker:- Sure.
Speaker:Sorry, I'll just take a brief pause there
Speaker:'cause I don't have more on me to.
Speaker:Yeah, we in the PIA have
had a quite diverse approach
Speaker:to our work groups.
Speaker:And we've got four different work groups
Speaker:and one of them is really heavily invested
Speaker:in trial design.
Speaker:We also have work groups on biomarkers,
Speaker:on developing research consortia,
Speaker:and also on prodromal Lewy body disease,
Speaker:which is, I suppose, analogous somewhat
Speaker:to mild cognitive impairment.
Speaker:And Alzheimer's disease.
Speaker:And one thing that these things,
Speaker:one thing that these
working groups have all done
Speaker:is they've acted as a lightning rod
Speaker:for the international Lewy body community.
Speaker:And it has provided such a great vehicle
Speaker:and such great exposure.
Speaker:And it's allowed us to move beyond
Speaker:the three or four or
five traditional giants
Speaker:in Lewy body dementia research,
Speaker:to diversify, to
democratise our community,
Speaker:and to bring more and more
people into the community.
Speaker:And we have had people
that have started off
Speaker:doing some of these projects,
Speaker:like a publication for
the trial methods group,
Speaker:for example.
Speaker:And in the case of my colleague,
Dr. Rodriguez Purcell,
Speaker:he started off doing a systematic
review on trial methods
Speaker:and now he's about to lead the PA.
Speaker:And then in other working groups,
Speaker:we've got really experienced colleagues
Speaker:working on biomarkers
Speaker:and really forwarding
the conversation there.
Speaker:And again, what they've done really well
Speaker:is just energised the broader community.
Speaker:So where you previously looked at
Speaker:some of these great reviews,
Speaker:you had maybe four or five people
Speaker:from the same groups, same
centres, contributing to them.
Speaker:And you look at some of our PA papers,
Speaker:and there's loads of authors
from all over the world.
Speaker:And the people that have
worked on these projects
Speaker:have stayed in Lewy body dementia,
Speaker:stayed in the PA,
Speaker:and they developed projects of their own.
Speaker:So the exposure and the
ability to grow our network
Speaker:has been something quite different
Speaker:from anything we've been able to do
Speaker:in the Lewy body dementia community.
Speaker:- Yeah, I've always
appreciated the ability
Speaker:to participate in working groups
Speaker:generated by the PAs.
Speaker:And exactly what you're saying,
Speaker:bringing groups together
from all over the world,
Speaker:giving early career researchers
Speaker:a chance to sort of contribute
Speaker:and work with some of
the giants in the field.
Speaker:You mentioned a prodromal working group,
Speaker:and I'm interested about that.
Speaker:How long is the disease
force in the prodromal stage?
Speaker:- Great question, and the
answer is we don't know.
Speaker:One of the things that
we've been really lacking
Speaker:has been longitudinal
Lewy body dementia data.
Speaker:And again, there's been a
few well-resourced centres
Speaker:that have really got their act together
Speaker:and put really cool
longitudinal projects in place.
Speaker:But the fact of the matter is
Speaker:that we don't fully understand conversion
Speaker:from prodromal disease to
full-blown Lewy body dementia.
Speaker:We don't fully understand the role
Speaker:that the biomarkers have to play in that.
Speaker:We don't fully understand what things
Speaker:like Alzheimer's pathology
has to play in that.
Speaker:And then the other big huge
thing is that we believe
Speaker:that the prodromal phase
of Lewy body dementia
Speaker:isn't just a cognitive one.
Speaker:And although we think of
MCI in the context of AD
Speaker:to be very much driven by
the cognitive symptoms,
Speaker:we also believe that there
are significant groups
Speaker:of people out there ticking along
Speaker:without much in the way
of cognitive symptoms.
Speaker:And the first evidence of their disease
Speaker:is psychiatric disease.
Speaker:So the first time somebody
has to ask the question
Speaker:is this Lewy body dementia
Speaker:could be their first depressive symptom,
Speaker:could be that they get psychosis
Speaker:or new hallucinations.
Speaker:And then there's also another group
Speaker:whereby we think that people get delirium.
Speaker:We know that people with Lewy
body dementia, for example,
Speaker:get delirium more frequently
in the lead up to diagnosis
Speaker:than people with Alzheimer's disease.
Speaker:So we also don't know
how that delirium onset
Speaker:prodromal disease then interacts
Speaker:with the full-blown dementia diagnosis.
Speaker:And it's a little easier
Speaker:and we've got a little bit more data.
Speaker:And in the PA, we've produced
a couple of really nice
Speaker:systematic reviews on the conversion
Speaker:from mild cognitive impairment to dementia
Speaker:and the neuropsychological characteristics
Speaker:of those patients.
Speaker:But huge, huge gaps remain
Speaker:around the psychiatric
and delirium prodromes.
Speaker:And that's something which is something
Speaker:we've got to really work on as a community
Speaker:and get the data and that's not that easy.
Speaker:- Yeah, and I think that
really highlights the need
Speaker:for early intervention,
Speaker:if those are some of the earliest signs.
Speaker:Those are really impactful
on patients' lives.
Speaker:- Yeah, I mean, different clinicians
Speaker:have different blind spots.
Speaker:And I'm a psychiatrist
Speaker:and if I see somebody
with psychiatric symptoms,
Speaker:focus on the psychiatric symptoms
Speaker:and I'm maybe not always
looking as closely
Speaker:as I could do about the
likes of cognitive symptoms,
Speaker:even with disease progression.
Speaker:So we need to work out how
this changes the behaviour
Speaker:of clinicians in different services
Speaker:with their different blind spots.
Speaker:And we've achieved so much in the realm
Speaker:of dream enactment behaviour,
REM sleep behaviour disorder,
Speaker:kind of sleep physicians
are now really, really good
Speaker:at identifying people at a high risk
Speaker:of the Lewy body dementia.
Speaker:And we could probably do better
Speaker:when it comes to psychiatrists,
Speaker:old age psychiatrists and
neurologists and geriatricians,
Speaker:maybe asking a bit more systematically
Speaker:about some of these psychiatric symptoms
Speaker:and scrutinising for
delirium a bit more closely.
Speaker:But we need the data, we need the studies
Speaker:and we can't really move
forward until we've done those.
Speaker:- Yeah, and I think that's
why these focus areas
Speaker:are so important, bringing
together different scientists
Speaker:with different backgrounds
to cover those blind spots.
Speaker:So what brought you to the PIA
Speaker:and how did you get first involved?
Speaker:- I didn't rack my brain about this
Speaker:because I've been involved in
the PIA for many years now.
Speaker:And I first got involved with
one of the PIA working groups
Speaker:just after the pandemic.
Speaker:And I had paused my research work.
Speaker:I had moved from Newcastle,
Speaker:which is one of those traditional giants
Speaker:and moved back to Belfast,
Speaker:didn't have the same and
doesn't have the same pedigree
Speaker:for Lewy body dementia research.
Speaker:And I really wanted to carry on the work
Speaker:that I'd done in my PhD.
Speaker:And this call went out saying,
Speaker:do you wanna work on a paper
about international consortia?
Speaker:I co-led that with Fabrizio D'Antonio
Speaker:and we worked really
closely with Dag Arsland
Speaker:and Jim Nevins,
Speaker:who are some of the absolute
giants in the field.
Speaker:And it was so much fun
putting that together.
Speaker:It was hard work, but
as part of that project,
Speaker:we basically had to reach out
to all Lewy body consortia
Speaker:that were occurring throughout the world.
Speaker:And it really gave me an idea
Speaker:of what the network looked like
Speaker:and really put me in contact
Speaker:with people I would never
have had contact with either.
Speaker:Shortly after that, I was asked
to be communications chair.
Speaker:And at the time I was tweeting a lot
Speaker:and that worked really well
Speaker:with tweeting about some
of my favourite subjects.
Speaker:And it was a really nice way
and a really exciting time
Speaker:to get people that were interested
Speaker:in Lewy body dementia interacting.
Speaker:And we ended up going
out for drinks at AIC
Speaker:and social media and getting out there
Speaker:has become a big, big part
of who we are as a PA.
Speaker:Definitely not because of me,
Speaker:but because of my successors.
Speaker:And then it was shortly after that
Speaker:that I became vice chair and then chair.
Speaker:So it's been absolutely
transformative for me
Speaker:as someone who,
Speaker:although I've been fortunate enough
Speaker:to work with some of the
real luminaries in the field,
Speaker:I am a little bit isolated,
it could be argued.
Speaker:And the PA just changes that,
Speaker:the PA just put me in the
middle of these networks.
Speaker:And it gave me the opportunity
Speaker:to work on some really exciting grants,
Speaker:to collaborate with people
Speaker:I would never have
collaborated with before.
Speaker:And sounds trite, but
they're all my friends now.
Speaker:We go to AIC and we look for each other
Speaker:and we have fun together.
Speaker:And yeah, it's been such a privilege
Speaker:and such a boon for my
career and for my life.
Speaker:So I'm very, very grateful.
Speaker:- Yeah, speaking of AIC,
Speaker:you mentioned you have one presentation.
Speaker:Does the PA have any
other activities going on?
Speaker:- Yeah, we're really
excited that this is maybe
Speaker:our biggest AIC for many,
many years in the PA.
Speaker:We have lots of activities going on.
Speaker:We were in PA day after
a brief hiatus last year.
Speaker:We're back to PA day
Speaker:and we're really happy with the
programme we've got lined up.
Speaker:We've got a kind of a panel discussion
Speaker:that's gonna look at not only the data
Speaker:around the seed amplification assays,
Speaker:but also how they might start to influence
Speaker:our decisions in the clinic
Speaker:and how you might start
figuring out clinical dilemmas
Speaker:using those biomarkers.
Speaker:We also, as part of that PA day,
Speaker:are really looking forward to awarding
Speaker:our first PA publication
of the year award,
Speaker:which is an amazing paper.
Speaker:I'm not gonna let the cat out of the bag,
Speaker:but we're really excited
Speaker:that it's such a quality
paper for our first award.
Speaker:Then straight up after that,
Speaker:we always really engage enthusiastically
Speaker:in the postdoc and student prizes.
Speaker:Probably one of my
highlights of AIC every year
Speaker:is visiting the Lewy body posters
Speaker:and seeing the early career researchers
Speaker:and the great work that they're doing
Speaker:and sharing it far and wide.
Speaker:So there's that.
Speaker:And then I think we've got
Speaker:three featured research sessions.
Speaker:I'm in one of them.
Speaker:And one small part of a
really exciting session
Speaker:that's going to talk about the integration
Speaker:of some of the new biological frameworks
Speaker:that have been developed
in Lewy body disease
Speaker:and in Parkinson's disease
Speaker:and how it might relate
to not only trials,
Speaker:but also practise and our cohorts as well.
Speaker:Then the last thing I'm
really excited about attending
Speaker:is a clinical toolbox session,
Speaker:which I think is on the last day.
Speaker:As a clinician, you're
looking every bit as much
Speaker:for some really good
clinical presentations
Speaker:as much as breaking research.
Speaker:And our PM members, Bhavna
Patel and Kate Wyman
Speaker:are gonna be sharing a really
broad multidisciplinary look
Speaker:at how to manage some of the
more troublesome symptoms
Speaker:in Lewy Body dementia.
Speaker:So I'm really looking forward to that.
Speaker:And I'm really looking
forward to seeing everybody
Speaker:and being face-to-face.
Speaker:And I'm really looking forward to seeing
Speaker:what my colleague Federico has in store
Speaker:for the next few years of the PM.
Speaker:- Yeah, congrats.
Speaker:That sounds like a really
productive programme at AAIC.
Speaker:And I'll have to stop by
and check some of those out.
Speaker:- Please do, please do.
Speaker:You'd be very welcome.
Speaker:(upbeat music)
Speaker:- All right, well, thank
you so much for your time.
Speaker:I think it's time to end today's podcast.
Speaker:Before we go, I do have a final question.
Speaker:So what advice do you have for someone
Speaker:who's just learning about ISTAART
Speaker:and how has it helped you being involved?
Speaker:- I think one of the things
that ISTAART has helped with
Speaker:is to provide,
Speaker:we talk about providing a platform,
Speaker:but it's actually a bit of a pedestal.
Speaker:It kind of raises you up.
Speaker:It's really levelling
and it really puts you
Speaker:at the same level of
some amazingly talented
Speaker:and experienced people.
Speaker:So my advice is to take that
opportunity with both hands.
Speaker:And what always surprised
me earlier in my career
Speaker:is that when I went up,
Speaker:I'm usually quite nervous in doing so
Speaker:and kind of gingerly
approaching really experienced,
Speaker:really important researcher in the field.
Speaker:How keen they were to speak
Speaker:with just about anybody on our topic.
Speaker:How keen they were to provide
people with opportunities.
Speaker:And how keen they were to,
especially with ISTAART,
Speaker:involve people as much as possible.
Speaker:So my advice would be, it's
such a great opportunity.
Speaker:Use it, try and set
your shyness to the side
Speaker:and ask that question
Speaker:because I guarantee it's
not a stupid question.
Speaker:- Yeah, completely agree.
Speaker:So thank you, Joe, for
taking time to join us today.
Speaker:- Thank you, Patrick.
Speaker:Really nice to speak with you.
Speaker:- So thank you for listening.
Speaker:You can find profiles of
myself and my brilliant guest
