From Narcolepsy Research to the Lasker Prize, Emmanuel Mignot’s Work Illuminates the Science of Sleep

Sleep appears ordinary until the boundary between waking and sleeping begins to disappear. For people with narcolepsy, that boundary can become unpredictable, turning an essential biological process into a daily medical challenge.

French researcher Emmanuel Mignot has spent decades studying that mystery. In September 2026, he and Japanese researcher Masashi Yanagisawa received the Albert Lasker Basic Medical Research Award for identifying orexin and establishing its role in maintaining wakefulness.

Mignot, a psychiatrist and pharmacologist based at Stanford University, began investigating narcolepsy in the late 1980s. His research eventually helped establish that the disorder is associated with a deficiency of orexin, a signaling molecule involved in keeping the brain awake.

The discovery emerged through years of research involving both humans and animals. Mignot studied narcoleptic dogs at Stanford, while Yanagisawa pursued a different scientific path that led to the identification of the orexin system.

Their findings eventually converged, revealing an important biological connection between orexin and wakefulness. The work changed scientists' understanding of narcolepsy and opened new possibilities for developing treatments that target the underlying mechanisms of the disorder.

Narcolepsy is considered a serious sleep disorder. Le Monde reports that around 6,000 people in France are affected, although the condition can be difficult to diagnose and may remain unrecognized for years.

The Lasker recognition arrives more than two decades after the researchers' foundational discoveries. The award is widely regarded as one of the major honors in biomedical research, and previous recipients have included scientists whose work later received the Nobel Prize.

The research has also begun to move toward practical treatments. According to Le Monde, new medicines targeting narcolepsy were approaching the U.S. market, while French sleep specialists were watching developments that could eventually expand treatment options in France.

Mignot's work has also extended beyond traditional sleep research. He has explored artificial intelligence and large datasets as tools for identifying patterns in sleep and developing new approaches to diagnosis and medical research.

The story of narcolepsy research is therefore one that stretches across decades, laboratories, countries, and scientific disciplines. What began with questions about why some people could suddenly fall asleep has developed into a detailed exploration of the biological mechanisms that help the human brain remain awake.

For Mignot, the Lasker Award marks a new point in a long scientific journey. For patients and researchers, the deeper significance lies in how fundamental discoveries about a small brain peptide can gradually move from laboratory findings toward a clearer understanding of sleep and new possibilities for treatment.
