Movement Disorders lab
The Bertram group performs clinical research in movement disorders, including Parkinson Disease, atypical Parkinsonism and dystonia. We are interested in the application of deep brain stimulation, stem cell technology and finding out better treatments with clinical trials and biobanking. We aim to improve diagnosis and treatment options for people living with Movement Disorders.
Our Work
Our research focusses on improving biomarkers for diagnosis of and clinical parameters affecting people living with Parkinson’s disease, Progressive Supranuclear Palsy, Multiple System Atrophy and Dystonia.
We are actively engaged in clinical trials bringing new treatment options to people with Parkinson’s disease, Parkinson’s disease dementia, Progressive supranuclear Palsy, Huntington’s disease and essential tremor. We lead the victorian component of the national Australian Parkinson’s Mission trial into medication repurposing aiming to find disease modifying agents for people living with Parkinson’s disease, and reseaching the genetics of medication response.
Investigator initiated research has included biomarker development for atypical parkinsonism including transcranial Magnetic Stimulation in Progressive Supranuclear Palsy and Multiple System Atrophy. We are also exploring potential links between Parkinson’s cognitive impairment and changes on TMS response.
