Daily consumption of 6-7 cups of tea was significantly negatively associated with volumes of white matter hyperintensity (WMH) and the anterior cingulate cortex (ACC). Additionally, a significant association with the anterior parahippocampal gyrus was observed only in males.

The lowest risk of incident dementia at a daily consumption level of 4\u20135 cups of tea (fully adjusted HR 0.804, 95% CI 0.752, 0.861) compared to non-consumption, consistent with the neuroimaging findings.
