  1. BADL: Basic Activities of Daily Living; IADL: Instrumental Activities of Daily Living; NPI: Neuropsychiatry Inventory; FBI: Frontal Behavioural Inventory. ES: Equivalent Scores (according to Italian normative data, range 0–4; 0 = poor performance to 4 better performance). (*) All MLEs were statistically significant (i.e different to zero using t-test: P < 0.05), and expressed mean values.
  2. (#) Statistically significant (P < 0.05) means differences between LC1 vs. (LC2, LC3) are bold-underline, while between (LC1, LC2) vs. LC3 are underline.
