Time course of events in the SATS according to the basic ADL capacity at NHP. Mean age at AD onset, illness duration, time from diagnosis (start of cholinesterase inhibitor treatment) to NHP, and survival time in NHs, in the four groups of participants (PSMS score: 6, 7–9, 10–14, and 15–30). The individuals who exhibited a PSMS score of 10–14 at NHP spent about 0.5 year shorter time in NHs and those who had a PSMS score of ≥15 at NHP spent an average of ~1.5 years shorter time in NHs compared with patients who had a PSMS score of 6 (no impairment) at NHP (P = 0.045). More impaired basic ADL at NHP and longer time between diagnosis and NHP showed a significant relationship (P = 0.048). No differences were found regarding age at AD onset, illness duration, age at diagnosis, age at NHP, and age at death among the four groups.
