Free Parkinson’s assessment calculators
Track Parkinson’s with validated calculators, free. Rate motor and daily-living function, quality of life, cognition, and tremor, and check the evidence behind each one.
How common it is
About 1 in 100 people over 60 have Parkinson’s disease.
About 1.2 million people in the United States are expected to be living with Parkinson’s by 2030, with roughly 90,000 newly diagnosed each year.1Worldwide, more than 8.5 million people have Parkinson’s, and the risk rises sharply with age.2

Understanding Parkinson’s
Parkinson’s disease develops as certain brain cells that help control movement are gradually lost. It can cause tremor, stiffness, slowness, and changes in balance, alongside non-motor effects on sleep, mood, and thinking. Because it progresses, these calculators are repeated to measure change.
They rate motor and daily-living function, quality of life, and cognition. A related movement disorder, essential tremor, has its own rating scale.

Each one is free. Open it to take the assessment, get a score, and see what it measures and the evidence behind it.
Motor and daily living
Could a brain-computer interface help?
The Brain-Computer Interface Registry connects people with Parkinson’s to trials building new ways to move and communicate. Complete your assessments once, and be matched to trials as they open.
These calculators use validated instruments and are reference information, not a diagnosis.
