The New York Times follows a young man's journey from coma to consciousness as aided by Ambien, and how two Philadelphia institutions are uncovering why.
This year, scientists at Moss Rehabilitation Research Institute and at the University of Pennsylvania, both in the Philadelphia area, began the first large-scale clinical study of zolpidem as a treatment for disorders of consciousness. (Amantadine, a drug used to treat Parkinson’s disease, and the anti-anxiety medication Ativan also show promise in increasing awareness in minimally conscious patients.) So far, the evidence suggests that less than 10 percent of brain-injured patients will experience the drug’s paradoxical effects, and that among those, only a few will respond as profoundly as Viljoen did. For families like the Coxes, such odds provide a tortured kind of hope. For doctors, they bring questions. Why does a sleeping pill induce awareness in some patients but not others? And what can these bizarre awakenings tell us about the brain’s ability to heal?
