PRIME data set

Description

This data set is from a longitudinal study called "Prospective Research in Memory Clinics" (PRIME), see Brodaty et al (2011), with a period of 3-year. The data set includes 583 dementia patients. The outcome is time to institutionalised. The predicators are age, sex, educational level, living status, dementia type, baseline cognitive ability (MMSE), baseline functional ability (SMAF), baseline neuropsychiatric symptoms (total NPI), baseline dementia severity (CDR), baseline caregiver burden (ZBI), medication types, change in cognitive ability at 3 months, change in functional ability at 3 months, and change in neuropsychiatric symptoms at 3 months. Note that this data set is complete and was analyzed by Brodaty et al (2014).
