NCT ID NCT07388160
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how general anesthesia affects certain brain chemicals and thinking skills. Researchers will compare 160 adults having gallbladder surgery: those who have never had anesthesia before and those who have had it multiple times. The goal is to understand if repeated anesthesia exposure is linked to changes in brain health.

Who is studied
This study will enroll adult patients aged 18-65 years scheduled for elective cholecystectomy surgery at Malatya Turgut Özal University Training and Research Hospital. Participants will be divided into two groups based on their previous general anesthesia exposure history: (1) patients with no prior general anesthesia exposure (control group, n=80), and (2) patients with at least one or more previous general anesthesia exposures (study group, n=80). Healthy volunteers with no previous surgical or anesthesia history will comprise the control group, while patients with previous surgical procedures requiring general anesthesia will comprise the study group. Both groups will be matched for age and body mass index. Participants with chronic neurological diseases, psychiatric disorders, metabolic syndrome, chronic inflammatory conditions, or recent immunosuppressive therapy will be excluded.
