Do more complex brain electrical signals protect again post-operative delirium?

Leah Acker, MD, PhD, Assistant Professor of Anesthesiology, Duke University Medical Center, Durham, NC Outside of the delirium field, less complex physiological output signals often are associated with increased risk of geriatric syndromes. For example, an increased risk of falls is associated with less complex musculoskeletal adjustment movements.1 Overall, less complex physiological signals are associated […]

Cognitive Prehabilitation to Prevent Postoperative Delirium

Contributed by Brian O’Gara MD MPH Department of Anesthesiology, Beth Israel Deaconess Medical Center, Boston, MA Postoperative delirium occurs in 15-50% of older surgical patients, and increases the risk of postoperative complications, hospital mortality and long-term cognitive dysfunction.1 Hospital -based multicomponent interventions can prevent postoperative delirium, but these approaches are only 30-40% effective.2 Therefore, there is […]
