Willoughby-Dudley KA, Darwin ML, Davalos DB. The Postoperative Effects of Anesthesia Exposure on Cognitive Decline in Older Adults: A Narrative Review. Curr Alzheimer Res 2024; 21:3-23. [PMID: 38623985 DOI: 10.2174/0115672050288199240408035201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 02/29/2024] [Accepted: 03/07/2024] [Indexed: 04/17/2024]
Abstract
BACKGROUND As modern medicine continues to make strides in effective surgical treatments, we must also consider the critical impact of anesthesia on neuropsychological outcomes. Recent evidence suggests that anesthesia exposure may be a risk factor for postoperative cognitive decline and the eventual development of dementia. OBJECTIVES To explore the vulnerability of the aging brain in the context of anesthesia exposure in surgery, studies will be reviewed, and pertinent findings will be highlighted and explored to better understand risks and possible factors that need to be considered when contemplating surgery. METHODS A narrative review was conducted using a combination of MEDLINE and APA PsycINFO databases to shed light on themes across studies assessing general trends regarding the influence of anesthesia on postoperative cognitive decline. RESULTS A search of relevant literature identified 388 articles. Excluding results outside the parameters of this study, the review includes quality assessments for 24 articles. CONCLUSION While findings are inconclusive, suggestions for further investigation into the relationship between anesthesia exposure and increased risk for postoperative cognitive decline are discussed, in addition to factors that may allow for greater informed disclosure of potential risks of anesthesia in older adults.

Physical frailty recovery is slower than mental frailty recovery after non-cardiac surgery in older adult patients. Langenbecks Arch Surg 2023; 408:395.

Abstract
PURPOSE Frailty is characterized by fragility and decline in physical, mental, and social activities; it is commonly observed in older adults. No studies have reported frailty status changes between the preoperative and postoperative periods, including mental and cognitive factors. Therefore, this study investigated frailty factors, including mental and cognitive functions, that change after non-cardiac surgery in older adults. METHODS Patients aged ≥ 75 years who underwent non-cardiac surgery were surveyed using five tools (Eastern Cooperative Oncology Group-Performance Status (PS); handgrip strengths; Japan-Cardiovascular Health Study index (J-CHS index); Mini-Mental State Examination (MMSE); and Geriatric Depression Scale) for comprehensive evaluation of perioperative functions. The results before surgery, at discharge, and during follow-up at the outpatient clinic were compared. RESULTS Fifty-three patients with a median age of 80 (IQR, 77-84) years were evaluated. MMSE scores did not change during the perioperative period. The PS and J-CHS index worsened significantly at discharge and did not improve at the outpatient clinic follow-up. The dominant handgrip strength decreased after surgery (p < 0.001) but improved during follow-up. Additionally, nondominant handgrip strength decreased after surgery (p < 0.001) but did not recover as much as the dominant handgrip strength during follow-up (p = 0.015). CONCLUSION Changes in physical frailty and mental and cognitive functions were not identical perioperatively in older adult patients undergoing non-cardiac surgery. Physical frailty did not improve 1 month after surgery, mental function recovered early, and cognitive function did not decline. This study may be important for frailty prevention in older adult patients.

Modified essential frailty toolset to determine outcomes following transcatheter aortic valve replacement. J Cardiol 2020; 77:341-345. [PMID: 32847756 DOI: 10.1016/j.jjcc.2020.07.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Revised: 07/08/2020] [Accepted: 07/13/2020] [Indexed: 12/23/2022]
Abstract
BACKGROUND Several predictors are available to guide patient selection for transcatheter aortic valve replacement (TAVR) to achieve better outcomes, and the essential frailty toolset (EFT) has been reported as one of those predictors. This study investigated whether a modified EFT could independently predict all-cause mortality following TAVR. METHODS The study population comprised 176 consecutive patients with severe aortic stenosis whose frailty was assessed with a modified EFT prior to TAVR at the Sakakibara Heart Institute between 2013 and 2018. The primary endpoint was all-cause mortality following TAVR. To understand the association between the modified EFT and all-cause mortality, multivariate Cox regression analysis was performed. In addition, to understand its predictive performance, we conducted a receiver operating characteristic (ROC) analysis. RESULTS Patients were elderly, relatively frail, and were likely to have significant heart failure symptoms. By the modified EFT definition, 40 patients (22.7%) were considered frail. With a median follow up of 1145 days, all-cause mortality at 1, 2, and 3 years was 6.2%, 10.2%, and 18.3%, respectively. Patients assessed as more frail on the clinical frailty scale had higher modified EFT scores. In ROC analysis, the area under the curve for predicting all-cause mortality at 1, 2, and 3 years was 0.79 [95% confidence interval (CI) 0.68-0.90]; 0.74 (95% CI 0.62-0.84); and 0.67 (95% CI 0.56-0.79), respectively, with the best cut-off modified EFT score of 1/2. CONCLUSIONS The modified EFT score was independently associated with all-cause mortality and had excellent predictive performance for all-cause mortality at 1 year.
