Abstract

Background.Delirium is a common syndrome affecting older people in hospital, whose pathophysiology is poorly understood, but sequelae of increased cognitive and functional impairment suggest neuronal loss.Methods.Cohort study comparing cerebrospinal fluid, blood, and clinical markers of delirium and neuronal cell death in 20 older hospitalized patients with delirium and 20 outpatients with Alzheimer's dementia.Results.Compared with participants with dementia, patients with delirium demonstrated higher CSF lactate (1.87 vs 1.48 mmol/L, p <. 001) and protein levels (0.62 vs 0.44 g/L, p =. 036) and lower levels of neuron-specific enolase (4.84 vs 8.98 ng/mL, p <. 001) but no difference in S100B. The changes correlated with clinical indices and outcomes.Conclusion.Older patients with delirium experience significant metabolic disturbance in the brain, which requires further investigation.
