Neurons communicate through electric signals, creating rhythmic brain activity known as "brain waves." When groups of neurons start firing at the same time, distinct brain waves form at various ranges. One such range is gamma waves, which play an important role in learning and memory. In Alzheimer’s patients, gamma waves are altered, indicating impairment in normal brain function.¹

Spectris AD is designed to evoke gamma wave activity through non-invasive visual and auditory stimulation. In our OVERTURE feasibility study, it demonstrated slowing of cognitive and functional decline and preservation of brain volume among treated Alzheimer's patients.
