Despite being the fastest-growing Neurodegenerative disease in the world, with cases expected
to surge to 30 million by 2030, Parkinson’s Disease (PD) currently has no definitive diagnosis. Current
methods of diagnosis are inaccessible to billions due to geographic, economic, and age-related mobility
barriers, disproportionately so in rural areas or regions without ready access to healthcare, such as
third-world countries; A single PD diagnosis can cost upwards of $5K, require a lengthy visit to a
nearby neurologist, and can involve intensive scans. Notwithstanding, currently, almost 1 in 3 patients
are misdiagnosed, and an estimated 40% of patients with PD are never successfully diagnosed with PD.
Since treatment is often more effective in the earlier stages of PD, these issues are vital to remedy so
that PD patients can be diagnosed as early as possible. ParkinSense, a web and mobile application, was
developed to combat these issues, and understand whether Machine Learning can be exploited for
accurate and rapid remote PD diagnosis and severity analysis. ParkinSense allows one to diagnose
themselves for PD from anywhere in the world in under 12 minutes, requiring only a webcam,
microphone, and internet connection. ParkinSense analyzes 4 cardinal symptoms of PD entirely
contactlessly and automatically: Dysarthia, Hypomimia, Tremors, and Bradykinesia. ParkinSense is
able to complete automated feature extraction. It was developed using recent innovations in Machine
Learning, in conjunction with over 16 machine learning models that utilize ensemble learning,
multimodal data fusion, and Bayesian Optimization to improve accuracy. ParkinSense boasts an overall
accuracy rate of 99.72% when trained on public databases totaling 9 million data points, synthetic
patients, and 124 authentic patients. Sensitivity, a valuable metric to maximize in medical Machine
Learning solutions, was 0.999. Even after proper diagnosis, there is a critical need to monitor PD
severity, to analyze disorder progression and the effectiveness of specific treatments. ParkinSense is
able to estimate the disease severity on the two common PD severity classification scales with a
normalized root-mean-square error of less than 0.0907. Together, ParkinSense outperforms average
diagnosis methods by 34%, and average classification methods by 223%. Furthermore, trends of
severity can be analyzed, for an assessment of treatment effectiveness, via a GUI. Results can be shared
in real-time with a Neurologist or family member for monitoring. Neurologists can submit DaTScan,
MRI scans, and other information to ParkinSense for further analysis and accuracy gain. Finally,
ParkinSense enables treatment, by predicting possible drug treatments, and by providing tasks that can
suppress and reduce the symptoms of Parkinson’s disease, entirely from home. This treatment saw a
substantial decrease in disease severity, on average, in 52 patients of different backgrounds and
cultures. During this study, all HIPAA Privacy, OSHA, local regulations, and IRB regulations were
followed to ensure patient privacy and safety. Not only is ParkinSense contactless, rapid, accurate, and
cheap, it is the first public method of remote PD diagnosis, telemonitoring, or treatment, potentially
providing billions with a crucial healthcare tool, that is otherwise essentially inaccessible to them.
Furthermore, ParkinSense was shown to be effective in both the early and late stages of PD, allowing
for early and more effective treatment. These advances can be translated over to other
neurodegenerative disorders, and diseases with digital biomarkers. Further research can be conducted
on unutilized extracted features, such as eye saccades, which could offer additional success.
