While surfing for more info on zyprexa/olanzapine, I came across this site: http://www.mhsource.com/edu/psytimes/answers.html which says gambling has been linked to elevated levels of central nervous system produced norepinepherine metabolites. Could a pallidotomy have set this off in the people who have been writing to report post-pallidotomy gambling problems? Plus, here are some phone numbers: 800 - 426 - 2537 Gamblers Anonymous 800 - 522 - 4700 Council on Problem Gambling. Mary Rack [log in to unmask]
