Most of widely available consumer devices like smartphones and tablets are equipped with various sensors that allow for detection of subtle and undetectable neurological impairment of various neurological functions like motricity, coordination, cognition, visual function or eye movements. This opens the perspective of earlier diagnosis of neurological diseases, even at the preclinical stage, which could allow for earlier therapeutic intervention and improved long term outcomes. In this article, we review how technology can enhance the clinician's examination skills and the current level of evidence in the field of preclinical diseases detection, in diseases like Parkinson's disease, Alzheimer's disease or multiple sclerosis. Many studies reported subtle impairment regarding fine motricity, eye movements, cognition, voice features and speech. We will also discuss current limitations regarding scientific evidence and practical implementation in the daily practice, as well as future perspectives.
