life. We compared changes in QOL measures over one year based upon diagnosis awareness in persons with AD and MCI using fixed effects analyses. Results:After one year, patients with AD or MCI who believed themselves cognitively normal at baseline showed, on average, a decrease in both satisfaction with daily life (QOLAD; PMD1⁄4-0.9, p<0.05) and physical wellbeing (SF-12 PCS; PMD1⁄4-2.5, p<0.05). They also reported less depression than at baseline (GDS; PMD1⁄4-0.1, p<0.05). In contrast, patients who believed themselves diagnosed at baseline showed no statistically discernable changes in QOL domains or physical functioning after one year (all p>0.05). However, they did show an average decrease in mental wellbeing from baseline (SF-12 MCS, PMD1⁄4-1.4, p<0.05) and were less likely to expect their memory to worsen over time (PMD1⁄4-11.7%, p<0.05). In subanalyses, those who retained their same level of awareness over time (63.1%) – be that aware or unaware – were less likely to expect their memory would worsen (p<0.05). Of those aware of their diagnosis at baseline (n1⁄4111), those who were still aware (n1⁄484) showed a decrease in mental wellbeing while this effect was not observed for those who were no longer aware at follow up (n1⁄427; SF-12 MCS). Conclusions:Persons initially unaware of their diagnostic label – either MCI or AD – experienced declines in QOL while those aware of these facts about themselves did not. These relationships are independent of the severity of cognitive impairment.
