MMSE = Mini-Mental State Examination. Probable AD = probable Alzheimer’s disease. Mixed AD = mixed Alzheimer’s disease with vascular component. DLB = dementia with Lewy bodies. QoL-AD = Quality of Life Scale for Alzheimer’s Disease. ADSC-ADL = Alzheimer’s Disease Cooperative Study Activities of Daily Living Scale. CCI = Charlson Comorbidity Index. values are from a Kruskal-Wallis test (continuous variables) or a Pearson chi-squared test (categorical variables).
