Geriatric gambling disorder: challenges in clinical assessment.

To the Editor: The gaming industry is growing rapidly, as is the proportion of older adults aged 65 years or older who participate in gambling (Tse et al., 2012). With casinos tailoring their venues and providing incentives to attract older adults, and with the increasing popularity of "pleasure trips" to casinos organized by retirement homes, plus active promotion of government-operated lotteries in many countries, this trend is likely to continue. Gambling disorder (GD) or "pathological" or "problem" gambling presents a public health concern in the geriatric population. However, ascertainment of its prevalence and diagnostic accuracy have proven challenging. This is largely due to the absence of diagnostic criteria specific to the geriatric age and rating scales validated for use in this population.
