Postoperative delirium accompanied by sleep disturbances is described as a significant concern in perioperative neurocognitive health. Emerging evidence suggests the two conditions may have a bidirectional relationship, but their underlying mechanisms remain poorly understood, and effective therapeutic interventions are currently lacking. ### What is Rhizoma Corydalis, the herb studied here? Rhizoma Corydalis is a traditional Chinese medicinal herb recognized for its analgesic and anti-inflammatory properties. According to the summary, it had not previously been investigated in the context of [cognitive impairment](https://cedclinic.com/acute-effects-partial-cb1-receptor-agonists-cognition/) and sleep regulation, which is the gap this study addresses. ### What did this study set out to learn, and how? The study sought to clarify the mechanisms by which Rhizoma Corydalis and its bioactive compounds mitigate cognitive deficits and disrupted [sleep architecture](https://cedclinic.com/sleep-architecture-cannabinoids-enhancing-sleep-quality/). It combined disease-target database mining and bioinformatics analysis with validation in both in vivo and in vitro models of neuroinflammation.
