CRP and Alzheimer disease: In older adults, increased levels of circulating CRP have been linked with higher rates of all‐cause morbidity and mortality (Hillary et al. 2024; Michaud et al. 2013), worse cognitive function and cognitive decline (Arce Rentería et al. 2020; Marsland et al. 2015; Singh‐Manoux et al. 2014; Tegeler et al. 2016), brain atrophy (Wang et al. 2022), and higher risk of Alzheimer's disease (AD) (Zhang et al. 2022).
