How a Flickering Light Holds Promise in Alzheimer’s Treatment and Prevention | Dr. Mai Nguyen
I’m thrilled to announce this exciting podcast episode featuring an inspiring and thought-provoking conversation with Dr. Mai Nguyen, CEO and Co-founder of OptoCeutics. Dr. Nguyen is a pioneering force in the field of neurotechnology, and in this episode, we unpack her revolutionary work using non-invasive light stimulation to enhance brain function and potentially prevent neurodegenerative disease. At the center of our conversation is the EVY, a 40 Hertz light stimulation device developed by OptoCeutics under Dr. Nguyen’s leadership. This device is designed to target and enhance gamma oscillations in the brain—a specific frequency range of neural activity (around 40 Hz) that is critically involved in memory, attention, and perception.
In recent years, scientific studies have linked disruptions in gamma oscillations with the progression of Alzheimer’s disease. By restoring these rhythms, the EVY device aims to provide a non-pharmacological, non-invasive way to support brain health. During our podcast, Dr. Nguyen explains how EVY works: the device emits flickering light at a precise 40 Hz frequency, which is thought to entrain brain activity to resonate at that same frequency. This gentle stimulation may help reduce amyloid-beta accumulation, improve neural connectivity, and promote immune system engagement in the brain—mechanisms that could slow or even reverse aspects of cognitive decline.
What sets Dr. Nguyen apart is not just her scientific brilliance, but her deep commitment to translating research into real-world solutions. She leads OptoCeutics with a clear mission: to bring accessible, evidence-based neurotechnology into homes and clinics, empowering people to take charge of their cognitive well-being. Her approach is both deeply human and rigorously scientific, blending innovation with empathy.
As you’ll hear in the interview, Dr. Nguyen’s work exemplifies the exciting convergence of biology, technology, and therapeutic application. She speaks candidly about the challenges of advancing a novel therapy in a world still catching up to the implications of gamma entrainment, and why mainstream medicine is just beginning to recognize the vast potential of non-invasive neuromodulation.
This episode is essential listening for anyone interested in the future of brain health, the science of neuroplasticity, and the promise of light-based therapies. Whether you’re a clinician, researcher, caregiver, or simply curious about how to support your brain as you age, Dr. Nguyen’s insights will leave you informed, inspired, and hopeful.
