Digital biomarkers in movement disorders

Digital biomarkers, including wearable devices, smartphones and other digital technologies, have the potential to revolutionize the diagnosis and management of movement disorders such as Parkinson's and Huntington's disease. In addition, digital biomarkers can be used to monitor the effectiveness of treatment in real-time, allowing for more precise and individualized treatment management. This can include adjusting medication dosages, tracking symptoms and side effects, but also identifying patterns of disease progression and, as such digital biomarkers could have the potential to be used as outcomes in prevention trials. This is an overview of current research on the use of digital biomarkers in movement disorders, including the potential benefits and limitations, as well as future directions for research in this field.
