Syntropic is developing a non-invasive, wearable device designed to treat depression by activating brain immune cells with light delivered through the eyes. Based on a pioneering discovery by the co-founding team at the Institute of Science and Technology Austria, Syntropic technology uses 60-Hz light to stimulate microglia, the brain’s immune cells, to enhance brain flexibility and restore neuroplasticity. This stimulation has consistently improved depression symptoms in preclinical models, offering a fast-acting, non-invasive and highly effective non-pharmacological therapy. This innovative approach addresses the urgent need for a selective, sex-independent treatment for depression without the side effects of medication, marking a significant advancement in mental health care.
