Staff Profile

Dr Alison Yarnall completed her PhD in 2013 at Newcastle University looking at biomarkers of cognitive impairment in Parkinson’s disease. She is now an NIHR BRC Clinical Senior Lecturer at the Translational and Clinical Research Institute, Newcastle University; Deputy Director of the Clinical Ageing Research Unit; and Honorary Consultant in Older People’s Medicine at Newcastle upon Tyne Hospitals (NuTH) NHS Foundation Trust. She has a particular interest in cognitive decline, gait and falls in people with Parkinson’s and other neurodegenerative diseases and has published more than 100 articles in this topic area.  She runs a specialist clinic for older adults with Parkinson’s and complex health needs in NuTH, in addition to a general medical memory clinic.
