40 Hz Light Neurostimulation for Patients With Depression (FELIX)

Summary

Recent research in mice models of Alzheimer's disease (AD) has demonstrated that one hour per day of exposure to 40 Hz flickering light therapy can halt the disease's progression, and improve cognition and memory. Moreover, recent data suggest that 40 Hz light stimulation may induce neuroplasticity and reduce neuroinflammation. In this study, the investigators aim to evaluate the antidepressant effects of 40 Hz light stimulation in Major Depressive Disorder (MDD). Patients will be exposed to 40 Hz invisible spectral flickering light (active setting) or continuous non-flickering white light (sham setting) in a home setting for 1 hour each day.
