Description
Ellene Yan and a large team present a 2026 journal article profiling which thinking skills are weakest in older patients before surgery. The Montreal Cognitive Assessment is a thirty-point screening test spanning seven domains, from memory to naming. In a post hoc analysis of a screening study, the test was given before surgery to 382 patients with a median age of seventy-three.
The group averaged 25.9 points, and thirty-five percent screened positive for probable cognitive impairment. Those patients scored worse across all seven domains, not just memory. Having twelve or fewer years of education was tied to weaker scores in several domains, including executive function, naming, and language. Outcomes were tracked at thirty and ninety days after surgery for later analysis.
