HealthDay News – Preoperative Brain Exercise May Lower Your Risk of Postoperative Delirium. This is according to a study published online November 11th in JAMA Surgery.
Michelle L. Humeidan, MD, Ph.D., of Ohio State University’s Wexner Medical Center in Columbus, and colleagues studied whether cognitive prehabilitation reduced the incidence of postoperative delirium in older adults. Patients aged 60 and over who underwent major, non-cardiac, non-neurological surgery under general anesthesia were randomly assigned to either electronic, tablet-based preoperative cognitive exercise (125 patients) or standard treatment (126 patients).
The researchers report that 97 percent of the patients in the intervention group completed some brain exercises (median 4.6 hours). The rate of delirium among the controls was 23 percent, compared with 14.4 percent in the intervention group. After excluding four patients from the intervention group who did not attempt cognitive exercises, the delirium rate was 13.2 percent (16 of 121). In patients with delirium in the study groups, there were no differences in the day or duration of postoperative onset of delirium or total delirium-positive days.
“Modifying the postoperative risk of delirium through brain exercise remains a novel concept in the early stages of the clinical trial, and based on this work, further investigation appears necessary, including an examination of ideal activities, timing and effective dosage,” write the authors.
