Overview
GammaCap is a modular, personal-scale device that delivers synchronized 40 Hz light and sound stimulation—integrated seamlessly into an everyday hat.
Inspired by research from the MIT Picower Institute showing that 40 Hz “gamma” sensory stimulation can promote brain health, our goal is to make the experience more comfortable, discreet, and measurable for people living with early-stage Alzheimer’s disease.
Unlike room-scale flickering light systems, GammaCap is worn like a normal hat—providing individualized exposure without disturbing others nearby.
Background
Recent studies at MIT and elsewhere suggest that entraining the brain at 40 Hz—the gamma frequency—may help support neuronal synchrony and reduce neurodegenerative markers in animal models.
However, most existing systems use flickering lights or speakers that affect everyone in the room. Patients’ families often find these intrusive or unpleasant, limiting consistent use.
GammaCap rethinks the delivery mechanism: a personal, portable, and socially acceptable format.
