Abstract:
The authors report the results of repeated cognitive function tests administered over 10 months to 82 patients between the ages of 55 and 82 who underwent elective surgery. The Mini-Mental State Exam (MMSE) score, 10 months after surgery, was modeled by a multivariate linear regression that included the baseline demographics, baseline cognitive functions, and immediate postoperative MMSE scores. Immediate postoperative MMSE scores were highly significant to 10-month postoperative MMSE scores not explained by baseline variables. The results suggest that immediate postoperative cognitive change may predict later postoperative cognitive decline.
