Dr. Tzoulis is a Professor of Neurology at University of Bergen. He is an expert on movement disorders and neurodegeneration, including dementia and parkisonism. Dr. Tzoulis's research focuses on exploring the role of mitochondrial dysfunction in Parkinson's disease (PD) with the aim to improve patient diagnosis and develop neuroprotective therapies.
Such causes include mutations in genes such as PRKN (Parkin) and PINK1. One advantage of getting Parkinson’s early in life is that it tends to progress more slowly. Early-onset Parkinson’s generally progresses slower and may have a better long-term prognosis.
