Dozens of studies confirm that another effective treatment for addiction is cognitive-behavior therapy, which teaches people to resist unwanted thoughts and habits.

Resting just above and behind the eyes, the prefrontal cortex helps people tame impulses. Typically, most people show a disproportionate distaste for possible losses compared with equal-sized gains.

In the past, the psychiatric community generally regarded pathological gambling as more of a compulsion than an addiction—a behavior primarily motivated by the need to relieve anxiety rather than a craving for intense pleasure. Addictive substances keep the brain so awash in dopamine that it eventually adapts by producing less of the molecule and becoming less responsive to its effects.

Ultimately, Shirley bet every dime she earned and maxed out multiple credit cards. Research to date shows that levels of gambling gamblers and drug addicts share many of the same genetic predispositions for impulsivity and reward seeking.

Shirley, now 60, currently works as a peer counselor in a treatment program for gambling addicts. They have found, as they explain in their paper in Molecular Psychiatry, that people with lower levels of the norepinephrine transporter in their brain, tend to take losing money less hard than do other people, which could of course, lead to gambling problems.

Back then, Shirley's counselors never told her she was an addict; she decided that for herself. To ease symptoms of Parkinson's, some patients take levodopa and other drugs that increase dopamine levels.
