Is this trial a fit for you?

Likely a good fit

Women aged 18 and older undergoing elective major gynecologic surgery (hysterectomy and/or salpingo-oophorectomy) under general anesthesia, able to complete Turkish MoCA.

Probably not a fit

Patients with pre-existing major neurocognitive disorders or conditions preventing MoCA assessment may not benefit from these findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational cohort in adult women undergoing major gynecological surgery under general anesthesia. Cognitive function is measured with the Turkish MoCA before surgery and on postoperative day 3 to identify POCD, defined as either a ≥20% drop from baseline or a ≥2-point decrease. Researchers will collect demographic, frailty, menopausal, inflammatory, and intraoperative data to analyze associations with POCD and to identify high-risk patients. Findings could support personalized perioperative neuroprotective approaches, though causality will not be established in this design.

Why it matters

Potential benefit: If POCD risk factors are identified, clinicians may tailor perioperative care to reduce cognitive decline.

How similar studies have gone: Previous research on POCD in surgical patients supports the relevance of perioperative factors, but this specific gynecologic surgery population is less studied.
