CSF catecholamine levels in patients with and without delirium in all cohorts. (A) CSF noradrenaline levels and (B) CSF adrenaline levels were higher among the hip fracture patients (all, n = 118) while (C) CSF dopamine levels were highest among the cognitively normal elderly (n = 122). Furthermore, hip fracture patients with delirium (n = 65) had compared those with no delirium (n = 52) (B) lower CSF adrenaline levels and (C) lower CSF dopamine levels. Medical delirium patients (n=26) also had lower CSF dopamine relative to the cognitively normal elderly. Larger and smaller lines represent median and interquartile range, respectively. Two-tailed P-values for comparison of two groups are obtained by Mann–Whitney U-test. Differences in the three cohorts (upper line) were analysed by Kruskal–Wallis test.
