John-Paul Taylor

Professor John-Paul Taylor

I am a Professor of Translational Dementia Research and honorary consultant in old age psychiatry at Newcastle University. Clinically I lead a specialist Lewy body dementia clinic in Newcastle upon Tyne and I provide liaison sessions to Parkinson’s clinics in Northumbria.

I have research interests in neurophysiology and neuroimaging and their application to dementia populations, particularly the Lewy body dementias. Specific areas of research include: 

·         Understanding the neurobiological basis for cognitive and neuropsychiatric symptoms in Lewy body dementias including cognitive fluctuations and visual hallucinations.

·         The application of novel neuroimaging and neurophysiological techniques in dementia

·         The clinical characterisation of visual hallucinations

·         Understanding the dynamic interaction between vision and cognition.

·         Developing new biomarkers which can be used for diagnosis, prognosis and treatment stratification.

Dr Julia Schumacher

I am post-doctoral research associate at the Institute of Neuroscience working with Professor John-Paul Taylor, Prof. Andrew Blamire, Dr. Peter Gallagher, Dr. Luis Peraza, and Prof. Marcus Kaiser. I am exploring cognitive fluctuations in dementia with Lewy bodies using resting state network analysis on MRI and EEG data.


Dr Lauren Walker

My main research interests lie in investigating the effects of multiple pathological lesions on clinical phenotype in neurodegenerative disorders (e.g. Alzheimer's disease and Lewy body disease). Using a quantitative clinico-patholigical approach we aim to tease is distinct clinico-pathologcal phenotypes which may ultimately lead to tailored treatment options for patients.

Dr Daniel Erskine 

My research is focused on Lewy body diseases, collectively the second most common form of neurodegenerative disease after Alzheimer's disease. Much of my current work is attempting to understand why Lewy bodies form and if they are harmful to neurons. 

I have a major interest in rare neurometobolic diseases, particularly those with mechanistic overlaps with Lewy body diseases such as sphingolipid storage disorders and mitochondrial diseases. I am currently leading neuropathological studies into the sphingolipid storage disorders metachromatic leukodystrophy, Krabbe disease and Tay-Sachs disease, and mitochondrial disease cases resulting from nuclear DNA variants, including a significant cohort with Lewy body pathology. I am also involved in further studies investigating the neuropathology of Alpers' syndrome, mitochondrial encephalopathy lactic acidosis and stroke-like episodes (MELAS) and myoclonic epilepsy with ragged red fibres (MERRF).

Kirsty Olsen

I am a research assistant within the Institute of Neuroscience/Institute for Ageing and currently work on the SHAPED study which focuses on visual hallucinations across eye disease, Lewy Body disease and dementia.  My main research interests concentrate on driving and dementia and I maintain a resource website related to this.  Recently we have produced a set of guidelines for clinicians.  The document - Driving with dementia or mild cognitive impairment: consensus guidelines for clinicians, the purpose of these guidelines is to provide clinicians with an understanding of their legal and clinical responsibilities, as well as a framework on which to base appropriate management of those who drive with a diagnosis of dementia or mild cognitive impairment.

Joanna Wilson

I am a PhD student under the supervision of Professor John-Paul Taylor and Professor Lynn Rochester, working in collaboration with the Lewy Body Lab and the Brain and Movement research group (BAM). I am investigating the neural correlates of gait in older adults, and how these alter in Parkinson's Disease.

Undergraduate Students

Emma Packer

I am a third year Biomedical Science student completing my dissertation under the supervision of Professor John-Paul Taylor and Kirstie Olsen. I will be utilising the data collected in the SHAPED study to investigate the relationship between visual acuity and the severity of visual hallucinations in individuals with Charles Bonnet syndrome, dementia and Parkinson’s disease.

Dr Prabitha Urwyler

•  I was a visiting researcher (Sept 2016 -July 2018) under the guidance of John-Paul Taylor. During my stay at Newcastle, my primary research focused on investigation of pre-stimulation oscillations/rhythms as a marker for visual hallucinations in Parkinson’s Disease dementia. Other projects that were simultaneously investigated was the validation of the North-East Visual Hallucination Interview (NEVHI) severity score and the prevalence of multimodal hallucinations across disorders. Another exploratory study was “Feasibility of Synchrotron-Based Microtomography to Identify α-Synuclein Oligomers in Post-Mortem Tissue”.

• My current position is as a senior researcher/deputy group leader at the ARTORG Center/Gerontechnology and Rehabilitation group, University of Bern at Bern, Switzerland. Current research in Bern cover 1) cognitive training and assessment tools as early diagnostic and prevention methods in older adults and pre-clinical subjects 2) Tele-rehabilitation and assistive technologies for neurocognitive disorders.
