MMSE, mini-mental state examination; PGDRS, Psychogeriatric Dependency Rating Scale; CSDD, Cornell Scale for Depression in Dementia; GMHR, General Medical Health Rating; CHF, congestive heart failure; DM, diabetes mellitus; COPD, chronic obstructive pulmonary disease; CAS, caregiver activity survey.

Routine medications was excluded because of the large amount of missing data (only 204 cases had data e cohort 2 had this data).
