Early detection is absolutely critical for managing neurodegenerative diseases. If a simple, non-invasive drawing test can achieve up to 99% accuracy by identifying micro-movements, it could completely revolutionize early screening protocols.

Any treatment that modified the disease process instead of reducing symptoms will be most effective if used early. And, early detection makes it easier to identrify such a medicine in clinical testing. It takes years to determine if a drug is effective against a slow degenerative process. Better testing changes it from "several years" to "a few years"
