Pathological gambling (PG) is a non-substance based addiction that shares many behavioral and neural features with substance based addictions. However, in PG behavioral and neural changes are unlikely to be confounded by effects of acute or chronic drug exposure. Changes in reward based decision-making in particular increases in impulsivity are hallmark features of addictions. Here we review studies in PG that applied three reward-related decision tasks: the Iowa Gambling Task, probability discounting and delay discounting. We discuss the findings and focus on the impact of addiction severity and the relation of effects to impulsivity measures. While there is evidence that PGs differ from healthy controls on all three tasks, there is only little support for a further modulation of impairments by addiction severity. Conceptually, delay discounting is related to impulsivity measures and findings in this task show a considerable correlation with e.g. questionnaire-based measures of impulsivity. Taken together, impairments in PG on these three tasks are relatively well replicated, although impairments appear to be largely uncorrelated between tasks. An important next step will be to conceptualize a process-based account of behavioral impairments in PG.

Background And Aims: Gambling is a public health issue and widespread advertising of gambling products may contribute to gambling harms. Sports-related gambling advertising includes advertising around sports games or for sports betting products. This review aimed to provide the most systematic and up-to-date review of the literature on the association between sports-related gambling advertising and gambling behaviour.

Background: Catechol-O-methyl transferase (COMT) inhibitors are routinely used to manage motor fluctuations in Parkinson's disease (PD). We assessed the effect of opicapone on motor symptom severity in levodopa-treated patients without motor complications.
Methods: This was a randomized, double-blind, 24-week, placebo-controlled study of opicapone 50 mg as adjunct to levodopa (NCT04978597).

Background: The public health impact of new nicotine products will depend on their use by different population groups. We assessed the prevalence of nicotine pouch use among youth and adults in Great Britain (GB).
Aims And Methods: Cross-sectional annual Action on Smoking and Health Smokefree GB Adult Surveys 2020-2024 (n: 12 247 to 13 266, 18+) and Action on Smoking and Health Smokefree GB Youth Survey 2024 (n = 2872 11-18-year-olds).
