Yes. it does.
For instance, based on your comments here, you could be said to be 'minimally conscious'.
Just a joke, son. Just a Joke.
Now, the real point is that there is a difference. Just as there is between COMA and PVS.
The difference is also in how it relates to the law. The ability to put Terri to death is allowed by a law in Florida that requires three components, one of which is a diagnosis of PVS.
Did you know that the DOCTOR whose name appears on the original diagnosis of PVS is not signed by the doctor. This is also one of the legal requirements.
Terri is being illegally killed, and you don't mind?
LOL!!!
That was funny!! :)
