Neural predisposing factors of postoperative delirium in elderly patients with Delirium thesis neck fracture Elderly adults are more likely to develop delirium after major surgery, but there is limited knowledge of the vulnerability for postoperative delirium. In this study, we aimed to identify neural predisposing factors for postoperative Among 57 elderly participants with femoral neck fracture, 25 patients developed postoperative delirium and 32 patients did not.

Then we evaluated gray matter GM density, fractional anisotropy, and the amplitude of low-frequency fluctuation ALFFand conducted a group-level inference. The predicted probability computed from the logistic model was significantly correlated with delirium severity.

These results suggest that the three components are the most important predisposing factors for postoperative delirium, and our prediction model may reflect the core pathophysiology in estimating the probability of postoperative delirium.

Delirium is an acute neuropsychiatric syndrome that is characterized by sudden alterations and fluctuations in consciousness and cognition.

The risk factors for delirium include aging, cognitive and sensory impairment, and major surgery 1,2and various clinical and psychological risk factors have been additionally identified 3—6. In a general hospital, elderly patients are more likely to develop delirium, particularly after a major surgery.

It is worth noting that delirium has a considerable impact on prognosis even though postoperative delirium mostly disappears within a few days. In fact, delirium can lead to adverse consequences including persistent cognitive decline 7,8.

Although elderly adults who are the same age undergo the same operation, some develop postoperative delirium while others do not, suggesting the existence of neural predisposing factors and the need for creating a prediction model. Identification of the neural predisposing factors is also important to shed light on the pathology of delirium.

The prediction of delirium may be useful because early intervention reduces the duration of delirium, length of hospitalization, and mortality in delirious patients 9. Nonetheless, the lack of known neural predisposing factors and a clinically available prediction model appears somewhat surprising given that numerous studies have identified risk factors of delirium.

Because delirium is a neurocognitive disorder accompanying brain dysfunction, several studies have been conducted to identify the neural substrates of delirium.

For example, structural neuroimaging studies have shown an association between abnormalities in the brain volume and clinical outcomes such as the duration of delirium and decreased cognition Our group reported that hyperconnectivity of functional networks between the posterior cingulate cortex PCC and dorsolateral prefrontal cortex DLPFC was observed during an episode of delirium Unfortunately, neurobiological evidence of delirium from these two studies could not be used to predict postoperative delirium because it was acquired during and after the resolution of delirium.Improving Nursing Care For The Elderly With Delirium Nursing Essay.
