How many times have you asked yourself, "When will they invent a pharmaceutical to treat people who suffer from not gambling?"

Fret no longer. Researchers at Glasgow's Southern General Hospital found that Parkinson's patients on dopamine become addicted to gambling at rates disproportionately higher than people not taking the medication.

What's surprising is that it's not really surprising. Dopamine turns on the brain's pleasure center. The more dopamine swimming around, the greater the rush. Research in neuroeconomics reveals that the idea of a winning bet triggers dopamine release just as if you cast a winning bet. A hypothesis put forward earlier this year by Irving Biederman of the University of Southern California and Edward Vessel of New York University suggests that the neurology of learning might not be far afield from that of drug addiction.
