A head worn device for treating Alzheimers disease. The head worn device has LEDs mounted to the device. A printed circuit board (PCB) is also mounted on the head worn device. The PCB has a microprocessor and a battery in electrical communication. The LEDs are in also in electrical communication with the microprocessor. The microprocessor is programmed to control the flashing of the LEDs so that they flash at a regulated frequency. The flashing LED light enters the eyes of the user and travels to the visual cortex for Alzheimers treatment. In a preferred embodiment the LEDs flash at a gamma frequency.
