Suppression of Endogenous Alpha Power Predicts Clinical Response to 10 Hz tACS in Major Depressive Disorder: A Double-Blind Randomized Controlled Trial
In a double-blind randomized controlled trial, while 10 Hz tACS did not significantly outperform sham in altering prefrontal alpha power overall, clinical improvement in major depressive disorder was specifically predicted by the suppression of endogenous alpha power at individual alpha frequencies, supporting the personalization of tACS parameters for future treatments.
