Concepts and controversies regarding tolerance and withdrawal in gambling disorder
Concepts and controversies regarding tolerance and withdrawal in gambling disorder
November 28, 2019

Gambling disorder is classified in the DSM-5 as a behavioral addiction. However, the inclusion of tolerance and withdrawal symptoms as diagnostic criteria for the disorder remains poorly understood and characterized by a lack of empirical support. While the need for increasing excitement is considered central to the concept of tolerance in gambling, alternative explanations for the phenomenon exist. Concomitantly, withdrawal may not be limited to neurobiological processes generating adverse subjective and physiological arousal that contribute to persistent gambling. Clarifying the concepts and functional role of tolerance and withdrawal in the addiction process has significant implications for accurate clinical assessment and targeted symptoms in the treatment of gambling disorders.

Prof. LU Shiyu received the Healthy Longevity Catalyst Award (Hong Kong) as Principal Investigator
Prof. LU Shiyu has been named a Principal Investigator awardee in the Healthy Longevity Catalyst Awards (Hong Kong), a regional arm of the Healthy Longevity Global Competition founded by the U.S. National Academy of Medicine. This international program backs bold, early-stage ideas that can extend healthy years of life and accelerate practical solutions for ageing and longevity.
Prof. LU’s winning project—on social prescribing of virtual reality–based urban greenness combined with a peer-support model—will conduct an effectiveness and feasibility study to assess whether immersive exposure to green environments, delivered through VR and embedded in community pathways, can strengthen mental health and well-being among older adults. The study is designed to generate real-world insights on feasibility, acceptability, and preliminary impact, with the aim of informing scalable, non-pharmacological approaches to support healthy ageing and positioning the work for subsequent phases of the global competition.
