Alarming Trend: Parkinson's cases have increased by 50% in the US alone from 2012 to 2022, jumping from 60,000 to 90,000 new cases per year.
By 2050, estimates suggest the number will reach 25 million worldwide. Yet early detection remains a significant challenge.
What if your keyboard could detect Parkinson's disease before you even know you have it?
You might expect Parkinson's patients to type significantly slower. However, the reality is more complex. The NeuroQWERTY dataset from MIT reveals subtle differences in typing patterns.
*This visualization shows key hold times between groups. Select keys to explore the differences.Overall, PD patients have 29.9% longer hold times on average.
You might expect Parkinson's patients to type much slower. But the data reveals something unexpected...
The UPDRS-III scale measures motor impairment severity. Higher scores = more movement difficulties. Does severity affect typing speed?
No patients selected
Key Finding: Wide variability in typing speed within both groups. Significant overlap suggests typing speed alone is not a reliable indicator of Parkinson's disease.
Typing speed alone isn't the smoking gun we expected. The PD vs Control groups show massive overlap in typing speed distributions. Most Parkinson's patients type just as fast as healthy individuals.
Key Insight: Even when combined with other metrics, speed remains an unreliable indicator. We need to look deeper than surface-level performance.
Looking beyond typing speed to examine keystroke timing. But not all timing measures are created equal.
Only one timing measure consistently differentiates between groups.
How long each key is held down
THE key biomarker
Flight time between key presses
No consistent difference
Overall words typed per minute
Overlapping distributions
What you're seeing: This simulation randomly samples from our enhanced dataset to demonstrate statistical testing in action. Blue dots represent control participants, while red dots show Parkinson's patients. The dashed lines show the running average for each group, and the p-value updates in real-time as more samples are added.
The Revelation: Try each metric and watch the pattern emerge. Key Hold Duration consistently shows significant differences (p < 0.05), while Typing Speed and Inter-keystroke Delay typically show no significant difference (p > 0.05). This proves that duration alone is the reliable digital biomarker for Parkinson's disease.
What you'll discover: Research shows that key press durations are the primary biomarker, with Parkinson's patients showing ~60% longer durations compared to control groups. Additionally, typing speed and inter-keystroke delays show no consistent statistical differences between groups.

Analyzing your typing patterns...
By plotting diagnosis probability against clinical features, we distinguish signal from noise and utilize clinically releveant classifiers for early Parkinson's detection. The best fit logistic regression line reveals key patterns. Features like UPDRS-III Score, Alternate Finger Tapping, and NeuroQWERTY Score emerge as strong indicators, while many others show little correlation.
These findings open new possibilities:
The Vision: Digital biomarkers from typing patterns could make neurological health monitoring as simple as typing an email.
The most valuable insights hide in details we typically ignore. While typing speed tells us little, millisecond-level timing reveals powerful biomarkers for neurological health.
Revolutionary Finding: Duration of key presses, not typing speed, serves as the definitive indicator of Parkinson's disease, opening new possibilities for early detection and monitoring.
This single measure could transform how we detect and monitor neurological conditions - making brain health assessment as simple as typing an email.
Using the NeuroQWERTY dataset from MIT, we analyzed keystroke timing patterns between individuals with and without Parkinson's disease.
The next time you type, remember: your keyboard might know more about your brain health than you think.
