IDDD, Interview for Deterioration in Daily Living Activities in Dementia (in each item the need for assistance is rated from 0=never to 4=always). T0, IDDD score on entry to the study; T1, IDDD score at week 6 after 5 weeks treatment. T0–T1, 20% improvement (≥0.8; shown in bold) is defined as clinically relevant change.
