And then again...

John Ray reports on something one of his correspondents said.

"The court record for Terrri Schiavo says she has "no cortical function" -this means that her brain waves show a flat electroencephalogram (EEG). A neurologist - a very trustworthy man - told me that this means that she has no cognitive function or awareness; The "following the balloon" test is meaningless - it can't be reliably reproduced; and even patients with only lower brain (brainstem) function do it sometimes. And such patients also show some reaction to sounds and touch. If this is true, there just isn't much to save. And Terri is NOT awake. And she is NOT going to "get better", as her parents have said. Terri's condition is NOT the same as the lady who "woke up" and "talked" after being in a coma for 20 years. The neurologist described this as a "locked in" syndrome. This is often the result of damage to the brainstem without "cortical" damage - this is caused by mechanical injury or stroke or bleeding. Terri, in contrsast, suffered "ischemic" damage - lack of flow of blood and oxygen to the brain - the cortex (thinking, consciousness, pain) is the first to be damaged - the most sensitive part of the brain to oxygen lack. The "locked in" patients may have normal brain function and be alert, as noted by EEG studies - which may demonstrate changes with stimulation and sleep patterns etc.. To the untrained eye, these two may look similar. Terri's condition is NOT the same as those who report "waking up" after years in a "coma". I believe a lot of well meaning people are sorely misinformed about Terri's condition".

Different River has a collection of articles that beg to differ.

It would be nice to hear from an independent neurologist. At this point, though, is there any authority both Michael and Terri's parents would agree on?
