Objectives
Narrative objectives1
The aim of this study is to clarify how neuroinflammation and immune function influence the onset, clinical manifestations, and prognosis of delirium, a condition whose risk increases with aging. By elucidating these mechanisms, the study seeks to facilitate the development of new therapeutic strategies targeting brain inflammation and immune function.

Assessment
Primary outcomes
To evaluate the severity of delirium in patients scheduled for cardiovascular surgery and to clarify its association with blood biomarkers reflecting neuroinflammation and immune function.
Key secondary outcomes
To elucidate the relationship between activated-astrocyte PET imaging and blood biomarkers reflecting neuroinflammation and immune function.
To elucidate the association between regional astrocyte activation and the onset and severity of delirium.
