Sleeping pill wakes men from coma

From the Guardian, Sleeping pill wakes men in vegetative state.

A drug commonly used as a sleeping pill appears to have had a miraculous effect on brain-damaged patients who have been in a permanent vegetative state for years, arousing them to the point where some are able to speak to their families, scientists report today.

The dramatic improvement occurs within 20 minutes of taking the drug, Zolpidem, and wears off after around four hours - at which point the patients return to their permanent vegetative state, according to a paper published in the medical journal NeuroRehabilitation.

If they can be awakened, react and speak with their families, how can they be in a permanent vegetative state?

Ralf Clauss of the nuclear medicine department of the Royal Surrey County hospital, one of the authors, said that clinical trials were now needed. He said the drug could have uses in all kinds of brain damage, including Parkinson's disease and Alzheimer's.
