The aim of our study is to analyze the effect of dementia on postoperative survival in first month (early mortality), six months, first year and overall period following hip fracture surgery. This retrospective study analyzed 581 elderly patients with surgically treated hip fracture in a single Level 1 trauma center between January 2012 and January 2020. Patients were divided into two groups according to dementia. The demographic data of the patients and the survival curves of the two patient groups were compared. Mean age of all patients was 82.61±8.1 years. Seventy-nine patients (13.6%) had dementia. Mean age of the patients with dementia (PD) was 84.9±6.75 years. The average survival time of all patients was 28.64±26.3 months. The overall mortality rate was 11% (62/581) for the first month, 26% (153/581) for six month and 34% (200/581) for one-year following hip fracture surgery. The mortality rate of the PD for the first month, six month and one year was 10%, 33% and 53%, respectively. The first month and six-month survival of two patient groups were statistically similar (p:0.896 and p:0.157, respectively). But, the PD had significantly poorer survival following hip fracture surgery at one year and overall follow-up period (p
