Is There Hope for People in a Persistent Vegetative State?

Yes! Modern neuroscience is shining a light on their minds

Today, many neuroscientists don’t even call it a persistent vegetative state. The new term is disorders of consciousness. One neuroscientist recounts, In the past 20 years, advances in neuroimaging techniques have allowed us to explore brain functions in these altered states of consciousness. One breakthrough study conducted at our lab, in collaboration with the University of Cambridge in the United Kingdom, involved 54 DoC patients. The researchers asked the patients to perform two mental-imagery tasks while they lay in a brain scanner. In the first, they were asked to imagine playing tennis; in the second, to imagine walking from room to room in their home – mental tasks that are associated with contrasting patterns of neural activity. Remarkably, five patients…

Can People in Comas Have Abstract Thoughts?

Neurosurgeon Michael Egnor discusses how we might test for that ability

In the recent podcast, “Michael Egnor on Whether People in Comas Can Think,” Robert J. Marks raised an interesting point with Egnor: Can people in comas think abstractly or do they form thoughts only at a much more basic level, given how physically distressed they are? The answer might surprise you.

Can Loved Ones in a Coma Hear Us?

Modern brain imaging studies show that very often they can. And, with help from new technology, they can answer us too

Pioneering research using brain imaging (fMRI) over the last fifteen years has shown that, even in deep coma, people can hear, understand, and respond. It’s no longer just anecdotes from caregivers. The controversial Terri Schiavo case might be decided very differently today.

New Evidence That Some Comatose People Really Do Understand

Researchers found mental activity in response to verbal commands even in some “completely unresponsive” patients

There is growing evidence that many comatose patients are quite aware of what is going on around them. For example, nurses are often very careful not to say upsetting things that the patient can hear because blood pressure often rises dramatically, even in deeply “unaware” comatose patients.
