The mean age of patients diagnosed with dementia was 82.6 (SD 5.3; IQR 80–86), versus 68.9 (SD 12.7; IQR 60–68) in patients not affected by dementia (p<0.001; Student’s t test). Females were 47 (57.3%) among patients with dementia and 288 (52.8%) among patients not diagnosed with dementia, respectively. The mortality rate was 62.2% (51/82) among patients affected by dementia compared to 26.2% (143/545) in subjects without dementia (p<0.001).
