Free epilepsy assessment calculators
Measure the impact of epilepsy with validated calculators, free. Score quality of life and how seizures affect daily life, and check the evidence behind each one.
How common it is
About 1 in 26 people will develop epilepsy at some point in their lifetime.
About 3.4 million people in the United States are living with active epilepsy, including 3 million adults and 470,000 children.1 Worldwide, around 50 million people have epilepsy, with about 5 million newly diagnosed each year.2

Understanding epilepsy
Epilepsy is a tendency to have seizures, which are bursts of abnormal electrical activity in the brain. Seizures vary widely in how they look and feel. Beyond the seizures themselves, epilepsy can affect mood, work, driving, and daily life, so these calculators often focus on quality of life.
Epilepsy assessment calculators
Each one is free. Open it to take the assessment, get a score, and see what it measures and the evidence behind it.
Could a brain-computer interface help?
The Brain-Computer Interface Registry connects people with epilepsy to trials building new ways to monitor and manage the brain. Complete your assessments once, and be matched to trials as they open.
These calculators use validated instruments and are reference information, not a diagnosis.
