Unraveling the Mysterious Clues of Delirium in Older Adults

Published on May 12, 2023

Delirium, a peculiar syndrome that can have serious consequences for older individuals, has piqued the interest of scientists. In this study, researchers embarked on a quest to uncover the secret biomarkers that may hold insights into this puzzling condition. They scoured through vast scientific databases like treasure hunters in search of treasure maps. After meticulously assessing 32 studies, they discovered that serum biomarkers such as C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), and interleukin-6 (IL-6) may play a crucial role in delirium. These biomarkers showed an intriguing tendency to increase in patients with delirium. Although the evidence does not favor any one biomarker yet, these three contenders have consistently stood out among the bunch. The researchers believe that by unraveling the mysteries of these biomarkers, they could gain valuable insights into the underlying mechanisms of delirium and pave the way for future studies. Whether you’re a seasoned sleuth or just curious, exploring the full research article will lead you deep into the labyrinth of delirium.

Delirium is a neuropsychiatric syndrome associated with increased morbidity and mortality in older patients. The aim of this study was to review predictive biomarkers of delirium in older patients to gain insights into the pathophysiology of this syndrome and provide guidance for future studies. Two authors independently and systematically searched MEDLINE, Embase, Cochrane Library, Web of Science and Scopus databases up to August 2021. A total of 32 studies were included. Only 6 studies were eligible for the meta-analysis, pooled results showed a significant increase in some serum biomarkers (C-reactive protein [CRP], tumour necrosis factor alpha [TNF-α] and interleukin-6 [IL-6]) among patients with delirium (odds ratio = 1.88, 95% CI 1.01 to 1.637; I2 = 76.75%). Although current evidence does not favour the use of any particular biomarker, serum CRP, TNF-α, and IL-6 were the most consistent biomarkers of delirium in older patients.
