The aim of this study is to clarify how neuroinflammation and immune function influence the onset, clinical manifestations, and prognosis of dementia, including Alzheimer's disease, a condition whose risk increases with aging. By elucidating these mechanisms, the study seeks to promote the development of new therapeutic strategies targeting brain inflammation and immune function.
