Abstract


We examined the relationships between amyloid-β PET and concurrent and longitudinal cognitive performance in 107 cognitively normal individuals with subjective cognitive decline (age: 64 ± 8 years, 44% female, Mini-Mental State Examination score 29 ± 1). All underwent 90-minute dynamic [

We examined the relationships between amyloid-β PET and concurrent and longitudinal cognitive performance in 107 cognitively normal individuals with subjective cognitive decline (age: 64 ± 8 years, 44% female, Mini-Mental State Examination score 29 ± 1). All underwent 90-minute dynamic [

), and we performed linear mixed models to assess the relationships between global [

and neuropsychological performance. Higher [

was related to lower concurrent Mini-Mental State Examination (β ± SE: −1.69 ± 0.63 p < 0.01) and to steeper rate of decline on tasks capturing memory (Rey Auditory Verbal Learning Task immediate [β ± SE −1.81 ± 0.81, p < 0.05] and delayed recall [β ± SE −1.19 ± 0.34, p < 0.01]), attention/executive functions (Stroop II [color] [β ± SE −0.02 ± 0.01, p < 0.05], Stroop III [word-color] [β ± SE −0.03 ± 0.02, p < 0.05]), and language (category fluency [β ± SE −0.04 ± 0.01, p < 0.01]). These findings suggest that higher amyloid-β load in cognitively normal individuals with subjective cognitive decline from a memory clinic is associated with lower concurrent global cognition and with faster rate of decline in a variety of cognitive domains.
