Chair Report

Annual Report 2017 13


















The New Zealand Brain Research

Institute (NZBRI) has continued to grow

its reputation as a major contributor to

research on the brain and neurological

disorders, both nationally and

internationally.


ur focus is to improve brain-health for our community
O through research, education and clinical practice. This work

is undertaken by an experienced and globally recognised team of
researchers and clinicians who have made major contributions to
conferences; supervised and undertaken research; and been involved

in collaboration through the Brain Research New Zealand Centre of
Research Excellence (CoRE) and through international connections.

Medical research is vitally important and the work of NZBRI
is especially so. Funding such research can be challenging and we
do appreciate the regular donations and generous bequests that

continue to make our work possible in an increasingly crowded
donor market.

The Friends of the NZBRI (FBI) continue to be champions for the
NZBRI cause, and we recognise their tremendous support in running
the NZBRI Golf Tournament and the Opera Meets Art. We also thank

Michael and Ivan Donaldson and the team from Pegasus Bay winery
for donating the proceeds of the inaugural Pegasus Bay Vine Run,
a total of $19,000, to NZBRI.

On behalf of the Board, I would like to acknowledge the
huge contribution and commitment of the NZBRI team. Dr Michael
MacAskill (Research Director) and Professor Tim Anderson (Clinical

Director) provide the board with expert advice. Our researchers
and administrators illustrate the importance of international

relationships and the power of collaborative endeavours to make
a difference in the lives of the community they serve.

14 New Zealand Brain Research Institute



















The achievements of individual researchers have been significant
and are detailed in the Research Director’s Report.

The CMRF administration team also plays a vital role in the
smooth running of NZBRI, with Kate Russell the General Manager
of CMRF also acting as the Commercial Manager for NZBRI.

Kate Russell, has continued to provide clear direction, strengthened
our operational practices and supported the development of
new relationships. Kate leaves us in June to take up a new role

at the Christchurch City Council and we wish to acknowledge
her contribution to NZBRI.
2017 has also seen some changes in our board composition.

Emeritus Professor Steve Weaver stepped down from his role as
an independent director once our two new independent directors

were appointed. His contribution to NZBRI was significant and we
thank him for staying on during this transition time. Our two new
independent directors joined us at the beginning of the financial

year. Virginia Spoors is Southern Regional Manager, Health and
Ability Services — St John of God Hauora Trust and Richard Sudell

is a consultant with a background in commercial, capital works
and transaction advisory services.
They join a strong team: Professor Ivan Donaldson,

independent director; Professor Ian Wright, Deputy Vice-Chancellor
(Research and Innovation) at University of Canterbury; Professor
David Murdoch, Dean and Head of Campus of the University

of Otago; Christchurch; Mike Stenhouse and Simon Carey,
CMRF representatives.
2017 has seen the board of NZBRI and CMRF continue

to work closely, with excellent support and relationships maintained
particularly through the CMRF representatives on our Board.

NZBRI operates under a financial structure, which is fully owned
by CMRF. Summarised financial and performance information
derived from the audited Performance Report for NZBRI for 2017

is included within this publication.

Annual Report 2017 15



















In summary the net deficit for the 12 months was $41,747. The 2017
financial year saw income from research grants being higher than

budget reflecting the quality of the research program. Research
expenditure was slightly behind budget.
CMRF continued its support with an underwrite contribution

of $200,000 from its funds plus a further $150,000 drawdown
of capital from the van der Veer fund held by CMRF.
Income of $1,288,068 included a grant of $125,000 from the

CMRF parent to support our administrative function. This helps us
optimise the monies spent on the provision of research facilities,
personnel and research projects. You will read of the significant

work undertaken in the extensive reports that form part of this
Annual Report.

The new Board undertook a full review of our strategic direction
in late 2017, seeking input from staff and involving senior researchers
in our strategic workshop. Our focuses on growing and enhancing

our research programmes; extending our collaborative relationships
and projects; and nurturing and retaining talent aim to extend

our reputation. While NZBRI is already performing well, our new
strategic direction focuses on next steps in research, reputation
and financial sustainability.

Report

Annual Report 2017 17


















A large part of the Institute’s work is

devoted to Parkinson’s disease. Although

we have a lot of clinical and research

expertise in working directly with people

with this condition, surprisingly little had

been learned about the wider picture of

Parkinson’s in this country.




n 1966, at the beginning of their careers, distinguished neurologists
I Martin Pollock and Richard Hornabrook reported the first local
estimates of the epidemiology of Parkinson’s. This was a landmark

paper internationally, being one of the first to highlight the high
rate of dementia in what was previously thought to be solely a

movement disorder. The study was, however, restricted to residents
of Wellington, and the only Ma¯ori patients they identified were rural-
dwellers and hence were not included.

A later study in 1992 was similarly limited to the city of Dunedin.
An authoritative national estimate of the frequency of Parkinson’s

was sorely needed, as international estimates are unlikely to
generalise to our unique population. Dr Toni Pitcher has led this
research, collaborating closely with biostatistician, Dr Daniel Myall.

They applied a “big data” approach, analysing literally millions
of prescribing records over a decade, cross-referenced to other
national and regional data sources. They estimated for the first time

the national prevalence (the number of people with the disease:
191 per 100,000 people), and the incidence (the rate of new cases:
29 per 100,000 people per year).

The risk of Parkinson’s increases dramatically with age, although
most previous studies have not directly examined beyond the age of

85. By being able to cover an entire national population, we could
give reliable rates up to age 100, and produced strong confirmation

18 New Zealand Brain Research Institute



















of previous hints that the risk of Parkinson’s actually begins to
markedly decline in the oldest-old (those more than 85 years of age).

This has important implications for our understanding of the disease:
it is related to old age, but not necessarily the ageing process itself.
Toni and Daniel are continuing this research, into a number of

questions of national and international interest.
During 2017, we had a healthy success rate for attracting
competitive research grant funding. NZBRI researchers submitted

23 research grant applications. Of those, ten were successful and
five were unsuccessful, while one was withdrawn due to success of
a similar application to another funding body. The outcomes of seven

others were still awaited. In total, $1.23 million of external funding
was attracted to support our research projects.

The Brain Research New Zealand/Rangahau Roro Aotearoa
national centre of research excellence was the most significant
external funder of our research in 2017. Through its national

competitive funding process, it invested in a number of our projects
to assess brain health (using sophisticated measures of MRI, EEG,

and brain proteins in blood samples). They also funded our follow-
up nation-wide epidemiology study, to investigate the effects of
rural living and of ethnicity and financial deprivation on rates of

Parkinson’s disease.
This external funding was in addition to the Institute’s
application of its own resources into research. Most particularly,

we acknowledge the value of the Orr Family Estate donation, which
has been sustaining our substantial Parkinson’s longitudinal research
for the past four years. That generous investment has enabled us to

maintain our team of skilled neuropsychological assessors, who have
an ongoing and close relationship with our large cohort of Parkinson’s

research volunteers and their families. Over the past four years, as
part of a project examining the decline of cognitive functioning in
at-risk patients, we have needed to step up our usual two-yearly

Annual Report 2017 19



















assessments to a 6-monthly cycle. It has only been with the support
of the Orr family that we have been able to maintain that intensive

level of contact with our patients and their caregivers.
Once again, it has been a pleasure to work this year with such
a talented and passionate group of researchers, clinicians, support

staff and graduate students. Please refer to the “Statement of Service
Performance” (SSP), attached to our financial report, to get a more
comprehensive account of their research, clinical, and educational

achievements in 2017. None of this would be possible, however,
without the continued generous devotion of time and energy from
our research volunteers and their families.

Output

Submit high-quality funding applications to competitive funding rounds
at external research funding bodies.

The Institute’s research activity is primarily funded by grants from external

sources. Any funds awarded are as the result of a competitive process, and the
quality of the work is assessed by national and international peer reviewers.

These measures were not reported in previous SSPs.

Outcome Funding received to enable research activity, by providing for
research costs and maintaining employment stability for externally-

funded research staff.

Most external research income is not directly awarded to the Institute and
hence does not appear explicitly in its Financial Statements. This is because
most of its research staff must apply for funding through their affiliated
university as the host organisation. Thus the Institute generates much more
research income than is apparent from its own Financial Statements.

Annual Report 2017 37


















An exciting initiative during 2017 has

been the establishment of our Dementia

Prevention Research Clinics (DPRCs) in

mid-2017 as part of our involvement in the

national collaboration, Brain Research

New Zealand (BRNZ) Centre of Research

Excellence.

his clinic is based at the NZBRI and is recruiting people with

T mild cognitive impairment (MCI). People with MCI have a
50% risk of ultimately developing dementia, especially Alzheimer’s
Dementia. Participants in this research clinic undergo extensive

assessment, including detailed cognition testing, MRI and amyloid
PET brain scans, and have blood samples stored in a biobank for

later analysis and, we hope, discovery of new markers.
Our clinic volunteers are then reassessed regularly for any
changes in thinking and memory, and follow-up brain scans and

blood tests. The aim of these DPRCs is to find and test new therapies
to help prevent and treat dementia. The multidisciplinary clinic is

staffed by nurse coordinator Marie Goulden RN, Neuropsychologist
Dr Karelia Levin, Psychologist Prof John Dalrymple-Alford,
Geriatrician Dr John Elliot, Neurology Fellow Dr Purwa Joshi,

and Neurologist Prof Tim Anderson, along with Dr Toni Pitcher
responsible for blood sampling and Dr Tracy Melzer for the MRI and
PET brain scans. We have just farewelled Dr Joshi but are pleased

to welcome Neurologist Dr Campbell Le Heron onto the clinic team.
We already have over ten people participating in our clinic with an
expected number of some fifty recruited per year.

The NZBRI is excited to host two young and energetic research-
minded neurologists who have joined the CDHB Neurology

Department. Dr Teddy Wu arrived early in 2017. Teddy has special
expertise and research interests in Stroke and undertook his PhD

38 New Zealand Brain Research Institute



















thesis work in Melbourne on cerebral haemorrhage (bleeding
in the brain). He will be furthering his Stroke research under the

auspices of the NZBRI.
Dr Campbell Le Heron joined us in April this year after
completing his PhD thesis research at the University of Oxford (UK)

on apathy in neurological disorders. Campbell is passionate about
research and his expertise and interests are in cognitive disorders
such as dementia, and movement disorders (e.g. Parkinson’s and

Huntington’s). We are pleased to host Teddy and Campbell and
grateful to the CDHB Neurology Department for facilitating their
research interests at NZBRI.

We have continued to host the CDHB Neurology Department
outpatient clinics at our clinical facility at 40 Stewart Street

on almost a daily basis. These clinics provide opportunities for
patients to participate in the NZBRI clinical research activities
and for teaching medical students from the University of Otago,

Christchurch medical school. Dr Debbie Mason has specialized
multiple sclerosis (MS) clinics and leads research and trials of

new therapies in MS, Dr Rod Duncan offers specialised epilepsy
expertise, whilst Drs Fink and Reimers have subspecialty interest
in stroke and nerve and muscle disorders.

Beyond these special areas, the Neurology clinics see people
with the full gamut of common neurological problems including
headache, dizziness, gait disorders etc. The NZBRI clinical

facility also hosts three specialised neurological nurses Helen
Skene (Parkinson’s), Jane Eagle and Jessica Deacon (MS) and
Movement Disorders research coordinator Dr Laura Paermentier;

they are critical in supporting the NZBRI clinical research and
pharmaceutical studies and overseeing advanced treatments

for Parkinson’s and MS.
I continue to conduct two specialised Parkinson’s and Movement
Disorders clinics, as well as a botulinum toxin treatment clinic

Annual Report 2017 39



















for people with various forms of muscle spasm. With Dr Sandy
MacLeod, Psychiatrist, and other members of a multidisciplinary

team I run regular Huntington’s disease (HD) clinics at the Institute.
We also continue to participate in the large international HD-Enroll
research study for those with, or at risk of HD, and have some 100

participants from Canterbury and other parts of the South Island.
We were pleased to host a Summer Student, medical student
William Muller who undertook a project on eye movements

in Huntington’s analyzing the eye movement data from many
thousands of people with, or at risk of, Huntington’s. The results
of William’s work will be presented in a poster at a major

conference in Hong Kong later in the year.
We are already well into another busy and productive year at the

NZBRI. At the heart of our endeavours is the desire to improve the
outlook for our patients with neurological disorders.

Research Reports












As in previous years, brain imaging

remains a key aspect of the research

we conduct at the NZBRI.


e continue to have studies that utilize both Magnetic

W Resonance Imaging (MRI) and Positron Emission Tomography
(PET) imaging to investigate many topics, ranging from child

development through to diseases of the elderly, and beyond.
2017 was an exciting year in terms of imaging hardware. Pacific
Radiology Group (PRG) installed a new research grade 3T MRI

scanner at St. George’s Hospital in early 2017. This state-of-the-art
facility will facilitate cutting edge research. Researchers from the
NZBRI have already begun to utilise this resource, with three new

studies commencing in 2017. The 3T GE scanner that we have used
since its installation in 2006 was moved from its previous home at
Hagley Radiology to a new private hospital, Forte Health. We carried

out quality assurance tests before and after the move, with studies
continuing to utilise the scanner in its new location.

In 2017, we performed 154 hours of MRI scanning and an
additional 26 amyloid PET scans on the GE PET scanner at Southern
Cross Hospital. This amounts to less scanning than in prior years,

however this can be attributed to the completion of the amyloid
PET study, the ‘down time’ associated with the scanner move, and

the delay in starting new studies on the new St. George’s scanner
(commissioned in February 2017). In total, 8 different studies utilized
imaging in their research.

The new imaging facility at St. George’s hospital hosted three
new research projects in 2017, including:
1. Voluntary tremor suppression in Parkinson’s disease (PI: Dr

Rebekah Blakemore, Medicine, University of Otago, Christchurch)

2. The Dementia Prevention Research Clinics (PIs: Prof John
Dalrymple-Alford, Psychology, University of Canterbury, and

Associate Professor Lynette Tippett, Psychology, University of
Auckland)

3. Unravelling the neural mechanisms of speech production: insights

from EEG and fMRI in people who stutter (PI: Dr Catherine Theys,
Communication Disorders, University of Canterbury)

A number of ongoing studies continued on the scanner that moved

from Hagley Radiology to Forte Health. The Parkinson’s disease
research group continues to be the largest user of imaging,

specifically using MRI to (1) track disease progression over time as
part of an ongoing longitudinal study, (2) investigate mild cognitive
impairment in Parkinson’s disease, and (3) test whether a programme

of physical and cognitive enrichment can alter the trajectory of
the disease. Two additional studies scanned participants on this

scanner:

1. Blood flow in Obstructive sleep apnoea (PIs: Richard Jones and

Carrie Innes)

2. Magnesium sulphate at 30-34 weeks gestational age
(MagNUM—PI: Prof Caroline Crowther, Liggins Institute, University

of Auckland)

Amyloid PET scanning completed recruitment in 2017 (actually Jan
2018), with two complementary studies acquiring data:


1. Amyloid deposition in PD with Mild Cognitive Impairment (PIs:
Tim Anderson & John Dalrymple-Alford)

2. Amyloid deposition in PD (excluding MCI—PI: Tracy Melzer)


Staff and Students:

Research Fellows Dr Toni Pitcher, Dr Daniel Myall, Dr Rebekah
Blakemore, and Dr Tracy Melzer were all directly involved in imaging

research, as were 7 students: 4 PhD students (Mustafa Almuqbel,

and 1 research assistant (Maddie Pascoe, NZBRI). These students
represent three institutions, across multiple departments.

Excellent progress was made during 2017,

most especially the continuation of data

collection for the Parkinson’s disease

progression study, student postgraduate

completions and grant successes.



ur progression study is becoming an extremely valuable source
Oof varied and complex longitudinal datasets on Parkinson’s

disease patients; it continues to cement our place within the
international consortium on cognitive changes in Parkinson’s, for
which Dr Daniel Myall is now taking a leading role in setting up an

international resource.
The longitudinal study also includes work towards completion of

our current Health Research Council (HRC) project (Genetics, brain
imaging and cognitive decline in Parkinson’s disease; Co-PIs Tim
Anderson and John Dalrymple-Alford).

Of several new grant applications, perhaps the most significant
is our latest HRC project application, Plasma a-synuclein as a
biomarker of cognitive impairment in Parkinson’s disease (Co-PIs Tim

Anderson and John Dalrymple-Alford); we await the final outcome
of this application in May /June. Related projects also await an
outcome (MJ Fox Foundation, submitted in Jan 2018), but we have

already had success with Lottery Health.
In other work, we are nearing the completion of our “cognitive

and physical exercise” intervention study in patients with
Parkinson’s; we await some follow up data to assess the impact of
this intervention.

Of particular note is a new development to examine
electroencephalography (EEG) as a biomarker for cognition in

Parkinson’s disease and its extension to Alzheimer’s disease. In
that regards, we achieved grant success from Brain Research New
Zealand, which includes two-years part-time funding for Reza

Shoorangiz, who recently completed his PhD at the NZBRI.
Among other success with the NZBRI was a full-time post-

doctoral fellowship for Kyla Horne (nee Wood) to begin new
MRI analyses, a new direction that stems from her important
contributions to the longitudinal progression study.

In addition, the Dementia Prevention Research Clinic (funded
by Brain Research New Zealand) commenced operations during
late 2017, with the appointment of a research coordinator (Marie

Goulden) and clinical neuropsychologist (Karelia Levin), and
a formal opening anticipated in August 2018.
