Abnormal Level of Arousal as a Predictor of Delirium and Inattention: An Exploratory Study

These exploratory findings suggest that abnormal LoA is a strong indicator of delirium. Also, abnormal LoA is strongly associated with inattention as measured by an objective cognitive test. These findings suggest that acute-onset abnormal LoA could be used as a trigger for delirium assessment in routine clinical practice. Future work will help to clarify further the interrelationships among abnormal LoA, inattention, and delirium.
