That gambling disorders are embedded (both as cause and consequence) in human distress should not be surprising. Chapter 3 aptly brings this point home, citing evidence of extensive comorbidity of other psychiatric disorders. In one study, 76% of an inpatient sample were diagnosed as suffering from major depression. Similarly, co-occurring bipolar, anxiety, attention deficit hyperactivity, and substance use disorders are found to be disproportionately high among pathological gamblers, as are personality disorders and attempted/successful suicide. An interesting chapter on categorization reviews shared features with obsessive-compulsive disorder, substance use disorders, and mood disorders. The chapter on adolescents and young adults documents an apparently higher rate of gambling among youth than adults and explores why this might be so. Although the risk for problem and pathological gambling decreases among the elderly, the chapter on older adults reviews how targeting the elderly with industry incentives to gamble can leave susceptible individuals to suffer with the consequences of excessive gambling, especially when it is combined with loss of traditional adult roles, physical disability, boredom, cognitive decline, and depression.
