Did you actually read what I wrote or just the words you randomly decided to?
I'll say it again: There has never been any, not a shred, of evidence to indicate that Olney's lesions have ever appeared in humans.
Part 2: there was evidence to indicate that Olney's Lesions could exist in rats, but that's essentially been shown for what it was: wrong.
A Chloral Hydrate analogue known to cause brain lesions is used as a preservative in some ketamine preperations.
Subsquent studies that compared Ketamine, Ketamine and the Chloral analogue, and the Chloral analogue in rats showed absolutely no indication of lesions in the ketamine group, and lesions in the combo and the analogue group. As I recall, the analogue-only group had the highest rate of lesions.
So, what exactly are these other 4 causes?
And I'll say it one more time: a. Olney's Lesions have never been seen in humans; b. modified studies have shown that ketamine doesn't cause brain lesions, but that a preservative in it does.
This is all coming from journals, not what people are claiming on BL. You can look through ADD for links to those articles. If that's too difficult, I can post them here tommorow afternoon. It's bedtime, get up at 4:30a, work, come home, sleep a bit, and then I'll find them for you if you haven't managed to find them on your own.
