Muse Brain Age
A research idea, not yet a tested measure.
Muse offers Brain Age: a weekly figure, from its EEG headband, saying how many years younger or older your brain looks than you are. Short answer: estimating age from brain recordings is a real research area, with moderate accuracy in lab-grade EEG. We found no published study of Muse Brain Age itself, or showing that the number, or a change in it, says anything about your future health. Muse’s own page notes a single reading can swing by several years.

Estimating age from brain recordings is real research: in lab-grade EEG, models predicted age with moderate accuracy. We found no published study of Muse Brain Age itself, or showing that a lower brain age, or changing it, says anything about your future health. Muse’s own page says one session can swing by several years.
