UNEEG Surpasses 500,000 Hours of Longitudinal Real‑World EEG Data
COPENHAGEN, April 22, 2026 – UNEEG Medical A/S, a medtech and AI company specializing in ultra‑long‑term brain monitoring, today announced that its real‑world subcutaneous EEG database has surpassed 500,000 hours of continuous longitudinal data.
A major milestone powering algorithm development, clinical decision‑making in epilepsy therapy, and drug development for brain health therapy.
The milestone represents more than 57 years of uninterrupted EEG recordings, collected from patients living their everyday lives and monitored over extended periods of time. The scale, continuity, and real‑world nature of the data make the database one of the most comprehensive of its kind.
“High‑quality longitudinal EEG data is essential for generating clinically meaningful insights,” said Jonas Dunn-Henriksen, Senior Director, AI & Science at UNEEG. “Reaching 500,000 hours marks a significant step forward in our ability to continuously refine our AI-algorithms, support physicians in optimizing treatment for epilepsy patients, and enable drug developers to make more informed decisions during therapy development.”
Enabling better decisions in clinical care and drug development
Traditional EEG recordings are often limited to short, intermittent snapshots recorded in an artificial environment, which can miss clinically relevant events and introduce uncertainty in both care and research. UNEEG’s growing database addresses this challenge by providing continuous, objective, realworld neurophysiological data across extended time horizons.
This depth of data enables:
- AI-Algorithm improvement through large-scale real-world brain health insights,
- Improved treatment optimization by providing physicians with objective, longitudinal insights into brain activity, and
- More robust drug development in epilepsy and sleep disorders by supporting proof‑of‑concept studies, biomarker development, and treatment effect assessment based on objective brain data.
As the database continues to expand, UNEEG strengthens its position as a provider of data infrastructure and analytics supporting both clinical practice in epilepsy and brain health drug development.
