Article Synopsis
  • Reinforcement learning relies on rewards and punishments, with dopamine playing a key role in modulating behavior, especially in dynamic situations like those seen in Parkinson's disease (PD).
  • The research investigates how dopamine affects learning and decision-making in PD, focusing on how medication impacts adaptability and the role of tonic dopamine in signaling the value of actions.
  • The study adapts a neurocomputational model to simulate reversal learning tasks, revealing a U-shaped relationship between dopamine levels and switch error rates, and highlights the importance of valence in learning, challenging existing views on dopamine's effects in cognitive processes related to PD.

Acute lymphoblastic leukemia (ALL) stands as the most prevalent form of pediatric cancer in North America, with a current five-year survival rate of 85%. While more children achieved ALL remission and transition into adulthood, the prevalence of long-term treatment-related effects, especially neurocognitive sequelae, remains significant. This study pursues two objectives.

To understand why some long-term childhood cancer survivors experience positive adjustment in the long run,[Q1] this study aimed to (1) explore associations between well-being, health status, social support, and emotion regulation (ER) strategies in a cohort of long-term childhood lymphoblastic leukemia (cALL) survivors, (2) identify the individual contribution of each ER strategy to well-being (3) and their interaction with social support. We used data from 92 participants from the PETALE cohort (51% female, aged 24 ± 7 years). Measures included well-being (WHO-5), health status (15D), social support (SSQ-6), cognitive reappraisal and expressive suppression (ERQ), and emotional processing and expression (EAC).
