The New York Times Magazine explores how a growing body of research is upending what doctors thought they knew about people in so-called vegetative states. The piece by Katie Engelhart reports that some patients long assumed to be entirely unconscious may, in fact, have hidden or "covert" awareness—raising unsettling medical and ethical questions. For decades, Engelhart explains, the vegetative state was treated as essentially hopeless: Patients might open their eyes or breathe on their own, but were believed to lack any inner experience. That assumption is now shakier. Brain-imaging studies show that a meaningful share of these patients can respond to commands—by altering brain activity—even when they show no outward signs of awareness.
In some cases, they can answer yes/no questions using these signals. That has led to a key distinction: Some patients are truly unconscious, while others are in a minimally conscious state, with flickers of awareness that are easy to miss or misdiagnose. One large-scale study estimated that as many as 1 in 4 "vegetative" patients had some level of consciousness. The article traces how this emerging science of "covert consciousness" collides with hospital routines, insurance limits, and family decisions about whether to continue life support. Read the full story, in which Engelhart follows Tabitha Williams, whose 30-year-old husband, Aaron, was diagnosed as being in a persistent vegetative state without consciousness after a cardiac arrest in 2024. Tabitha, however, believes otherwise.
