Biomarkers have been crucial in transforming clinical practice in several therapy areas by enabling precision medicine. With the increase in use and popularity of digital devices and health related mobile apps, we are witnessing the emergence of digital biomarkers. We are seeing innovative applications of voice as a digital biomarker to detect depression or dementia, while digital biomarkers related to movement, balance and dexterity are increasingly used in monitoring and assessing manifestations of neurological disorders.
In order to understand how biomarkers will shape the future of healthcare, we need to define what a digital biomarker is and how we can use them.
