Transforming Neurological Care in 30 Seconds with QDG Health

Filling an unmet need for Parkinson’s disease

The number of people living with Parkinson's disease (PD) globally has doubled in the past 25 years. It is expected to double again in the next 15 years[1]. As the fastest-growing neurological disease, PD has been called an emerging pandemic. In the same amount of time, we have seen no significant innovations in PD drug therapies and a stagnation in the number and availability of neurologists to care for people with PD (PwP).

PwP, their care providers, and the therapeutic industry experience a critical unmet need: they lack a health management system that can provide remote symptom monitoring and AI-informed therapy adjustments in real-time, and which can provide high-resolution metrics of disease for clinical trials similar to the system that has revolutionized diabetes management using Continuous Glucose Monitoring (CGM) platforms.

To address this need, Dr. Helen Bronte-Stewart – director of the Human Motor Control and Neuromodulation Lab and John E. Cahill Family Professor of Neurology and Neurological Sciences at Stanford – has developed Quantitative Digitography (QDG) technology and created QDG Health: a comprehensive health management system whose technology provides validated, quantitative measures of all cardinal motor signs of PD in real-time from a 30-second repetitive alternating finger-tapping (RAFT) task on a proprietary digitography device (KeyDuo). A recent paper [2] published in npj Parkinson’s disease posits QDG as a high-resolution tool for objective motor monitoring with promising remote and in-clinic utility.
