"Like most addictions, Townsend-Lyon’s gambling problem didn’t come out of nowhere. Similar to most women with addiction, she’d had a traumatic childhood—including emotional and physical abuse and ongoing sexual abuse by a close family member and another perpetrator. Also, like most women with addiction, she had pre-existing psychiatric problems; in her case, obsessive-compulsive disorder, post-traumatic stress disorder, and bipolar disorder.
Studies of addicts show that trauma and certain genetic vulnerabilities—especially the two in combination—increase risk for a wide range of mental illnesses and a bewildering spectrum of addictions that include gambling, sex, alcohol, and opioids. The availability of escapist drugs and activities help determine what form the problem takes. But gambling and drugs themselves don’t cause addiction, a myth that often interferes with getting to the personal root of the problem."
