Anhedonia is a symptom encompassing reduced or absence of motivation and pleasure that often emerges in adolescence and conveys risk for different mental illnesses and other difficulties. In their review, Gupta, Eckstrand, and Forbes (Journal of Child Psychology and Psychiatry, 2024) present an empirically‐based conceptual neurodevelopmental model of anhedonia whereby brain development and pubertal maturation create openness to vulnerability to anhedonia that is influenced by early life adversity and chronic inflammation. This commentary considers anhedonia as a paradox of adolescence given its juxtaposition to the expected developmental milestones of adolescence. It highlights the need to consider anhedonia in terms of both variability and universality of children's experiences and biological development, missed opportunities for social relationships and experiences, and forms and functions of rewards and anhedonia.

理解悖论：青春期的快感缺乏和与奖励寻求的意外分歧——对古普塔等人的评论。 (2024)

快感缺乏是一种包括动力和快乐减少或缺乏的症状，通常出现在青春期，并带来患不同精神疾病和其他困难的风险。 Gupta、Eckstrand 和 Forbes 在他们的评论中（儿童心理学和精神病学杂志，2024）提出了一种基于经验的快感缺乏概念性神经发育模型，其中大脑发育和青春期成熟创造了对快感缺乏的脆弱性的开放性，这种脆弱性受到早年逆境和慢性炎症的影响。本评论认为快感缺乏是青春期的一个悖论，因为它与青春期预期的发展里程碑并列。它强调需要从儿童经历和生物发育的可变性和普遍性、社会关系和经历的错失机会以及奖励和快感缺乏的形式和功能方面考虑快感缺失。
