Introduction
I am a Consultant Physician, Honorary Professor of Ageing and International Health, with an interest in healthcare of the elderly, at North Tyneside General Hospital where I was appointed a consultant in 1995. I have a special interest in Parkinson’s Disease (PD) and I am the Clinical lead for Northumbria PD Service. I am Director of R&D for the Trust and I am closely involved both locally and nationally with the DeDRoN Research Network.
My main research interest in the UK is Parkinson’s disease. In Sub-Saharan Africa (SSA), specifically Tanzania, I have a research interest in stroke and Parkinson’s disease. Non-communicable diseases are
Background
My MD thesis was on the risk factors, and outcome, for stroke in the Gambia, West Africa and I have also published the largest ever prevalence study of stroke in Sub-Saharan Africa, from Tanzania as well as the largest mortality (by verbal
autopsy) stroke study in SSA, also from Tanzania. In Tanzania we have just completed the first ever community-based stroke incidence study in SSA and we are presently preparing the results for writing up. We have also just conducted the first Parkinson’s disease prevalence study in SSA (also in Tanzania).
Research
RW’s research interests in PD in the UK include epidemiology, psychiatric symptoms, palliative care, respiratory symptoms and exercise. He was on the PD NICE Guidelines Development Group (published July 2017) and is on NICE PD Quality Standard Advisory Committee. For Dementia and Neurodegenerative Disease Research Network (DeNDRoN) he is the north east lead for PD research and on the national Portfolio Development Group and National Speciality Group.
He has been involved in research in SSA since 1989 and has published extensively (over 170 peer-reviewed articles). He has previously received research funding from Parkinson’s UK for epidemiological research on PD, including long term outcomes, in Tanzania. This funding supported the only published robust PD specific prevalence study in SSA and investigation of cueing as a treatment for drug-naive patients (with LR).5,10
RW led the Wellcome Trust funded Tanzanian Stroke Incidence Project (TSIP) which is still the only fully community-based stroke incidence study from SSA and led to a seminal paper in Lancet Neurology.17 A subsequent publication in Lancet Global Health demonstrated for the first time that HIV independent of medication side effects was a risk factor for stroke.18 The study has led to 14 publications and is widely cited. It demonstrated some of the highest age-adjusted stroke incidence rates in the world.
His other interests in non-communicable diseases in SSA include epilepsy, hypertension, atrial fibrillation, dementia and frailty. The dementia research is currently funded by Grand Challenges Canada (IDEA study) and NIHR (DePEC study).We are now developing an app for screening for dementia and cognitive impairment which we plan to trial in 2018. As chief investigator, he also has MRC Confidence in Concept funding of £50,000 for a randomised controlled trial to look at beetroot and folate as treatment for hypertension in Tanzania.
In 2009 he set up the SSA interest group (ATF since 2012) within the MDS which he Chaired until June 2017, and remains on the committee. He is Associate International Director (AID) for SSA for the Royal College of Physicians (RCP) in London (since September 2016) and he has numerous contacts throughout SSA with research active clinicians with an interest in PD. He is part of the RCP faculty for the East African Development Bank (EADB) funded East African Neurology Training Programme which commenced in 2016.

Research Interests
I am the head of the Northumbria Parkinson’s Disease (PD) Service, which was mentioned three times in the National Service Framework for Chronic Conditions Good Practice Guide in 2005 and was a finalist in the Health Service Journal Awards in the Patient Access Category, also in 2005. My main research interests in Parkinson’s disease are primarily clinical involving epidemiology, palliative care, pain, service use, sexual dysfunction and falls, and presently autonomic dysfunction and its relation to urinary dysfunction as well as cause-specific mortality of PD.
In Sub-Saharan Africa (SSA) I have published on the outcome, prevalence, and mortality from stroke and was principle investigator on a recently completed stroke incidence study in Tanzania which is the first community-based stroke incidence study in SSA. Also in Tanzania we have just carried out the first Parkinson’s disease prevalence study in SSA, and are presently investigating the impact of treatment in the individuals identified.
Other Expertise
I am the director of R&D for Northumbria Healthcare NHS Foundation Trust and I am also the Clinical Lead for a higher educational link between Northumbria Healthcare NHS Foundation Trust and Kilimanjaro Christian Medical Centre (KCMC), Moshi, Northern Tanzania.
Current Work
We are currently looking at autonomic dysfunction in PD, and the relationship of this to bladder dysfunction. We are also looking at cause – specific mortality in PD and place of death.
In Tanzania we have just completed, and commenced writing up, the Tanzanian Stroke Incidence Project. We have just completed the first Parkinson’s disease prevalence study and are presently investigating drug intervention in the cohort of individuals identified.
Future Research
I am hoping to continue recruitment for the Tanzanian Stroke Incidence Project and find further funding to maintain this. We are keen to investigate genetic aspects in relation to both the Parkinson’s disease and stroke work in Tanzania, and have DNA stored with respect to this. We are keen to specifically investigate cognitive impairment and dementia following stoke in Tanzania and are collaborating with Professor Raj Kallaria in relation to this. I hope in the future to be successful in applying for a programme grant to continue research in Tanzania focusing on neurological disability and the impact of interventions such as physiotherapy.
Research Roles
I am the principal investigator on the Tanzanian Stoke Incidence Project and on the Parkinson Disease Prevalence Study and the Director of R&D for Northumbria Healthcare NHS Foundation Trust.
Postgraduate Supervision
I have already successfully supervised three MDs with a fourth about to submit, and a fifth due to submit in 2008.
Esteem Indicators
In April 2006 I was awarded a national bronze award.
I am a reviewer for prestigious journals such as Lancet Neurology, Stroke and Movement Disorders.
