Patients without POCD - controlsGenotypingOut of the 976 patients included in the ISPOCD2 study (Abildstrom H, Christiansen M et al. Apolipoprotein E genotype and cognitive dysfunction after noncardiac surgery. Anesthesiology 2004;101:855-61) the 93 patients with POCD whose blood samples are stored will be included together with 2x93 controls (without POCD), who will be matched by type of surgery, age, education, ASA-score and sex.
