TL;DR: It is suggested that pathological gambling was a heterogeneous disorder in terms of loss aversion, which means that a loss is subjectively felt to be larger than the same amount of gain, and might be useful for understanding cognitive and neurobiological mechanisms and the establishment of treatment strategies for PG.

TL;DR: The study suggests that the heterogeneity of GD is underpinned at the brain structural level, which might be useful for understanding neurobiological mechanisms and for the establishment of precise treatment strategies for GD.

TL;DR: The present study provided the first empirical evidence of a deficit of state-dependent strategy optimization in GD, and highlighted diminished functioning of the dorsolateral prefrontal cortex (dlPFC), which has been heavily implicated in cognitive flexibility.

TL;DR: The findings indicate that alteration in the amygdala might play a significant role in risky decision‐making of GD and longitudinal studies are recommended to examine the causal relationship between brain abnormalities and risky decision-making in GD.

TL;DR: Investigating the neural correlates during decision-making under sunk costs in gambling disorder found a reduction in the neural activation in the dorsal medial prefrontal cortex for the GD group compared with the HC group, and in patients with GD, the levels of activation in this area negatively correlated with the duration of illness.
