Researchers have identified a strange side effect to a treatment for Parkinson's disease: excessive gambling.
Some patients taking medications known as dopamine agonists developed the problem within six months of starting treatment, even though they had previously gambled only occasionally or never at all. "This is a striking effect," remarks J. Eric Ahlskog of the Mayo Clinic, a co-author of the new study. "Pathological gambling induced by a drug is really quite unusual."
