Characteristics of subjective cognitive decline associated with amyloid positivity

Olin Janssen et al. Alzheimers Dement. 2022 Oct.

Abstract

Introduction: The evidence for characteristics of persons with subjective cognitive decline (SCD) associated with amyloid positivity is limited.

Methods: In 1640 persons with SCD from 20 Amyloid Biomarker Study cohort, we investigated the associations of SCD-specific characteristics (informant confirmation, domain-specific complaints, concerns, feelings of worse performance) demographics, setting, apolipoprotein E gene (APOE) ε4 carriership, and neuropsychiatric symptoms with amyloid positivity.

Results: Between cohorts, amyloid positivity in 70-year-olds varied from 10% to 76%. Only older age, clinical setting, and APOE ε4 carriership showed univariate associations with increased amyloid positivity. After adjusting for these, lower education was also associated with increased amyloid positivity. Only within a research setting, informant-confirmed complaints, memory complaints, attention/concentration complaints, and no depressive symptoms were associated with increased amyloid positivity. Feelings of worse performance were associated with less amyloid positivity at younger ages and more at older ages.

Discussion: Next to age, setting, and APOE ε4 carriership, SCD-specific characteristics may facilitate the identification of amyloid-positive individuals.

Keywords: Alzheimer's disease; amyloid; cerebrospinal fluid; positron emission tomography; subjective cognitive decline.

Amyloid positivity by age within APOE ε4 carriers (A‐D) according to different subgroups of setting and informant confirmation (3A), setting and memory complaints (3B), setting and attention/concentration complaints (3C), or setting and depression (3D); and amyloid positivity by age within a memory clinic setting according to different subgroups of APOE ε4 carriership and education (3E), or APOE ε4 and feelings of worse performance (3F). Note: (A–D) show interaction with setting, and (E and F) show interactions with APOE ε4 carriership or age. A was based on the model including age, setting, APOE ε4 carriership, and informant confirmation of complaints, and shows estimated amyloid positivity for APOE ε4 carriers only. (B) was based on the model, including age, setting, APOE ε4 carriership, and complaints specific to memory, and shows estimated amyloid positivity for APOE ε4 carriers only. (C) was based on the model, including age, setting, APOE ε4 carriership, and complaints specific to attention/concentration, and shows estimated amyloid positivity for APOE ε4 carriers only. (D) was based on the model including age, setting, APOE ε4 carriership, and depressive symptoms, and shows estimated amyloid positivity for APOE‐ε4 carriers only. (E) was based on the model including age, setting, APOE ε4 carriership, and education, and shows estimated amyloid positivity for a memory clinic setting only. (F) was based on the model including age, setting, APOE ε4 carriership, and feelings of worse performance, and shows estimated amyloid positivity for a memory clinic setting only. Results shown in (A–D) show a similar pattern for APOE ε4 non‐carriers, and results shown in (E and F) show a similar pattern for persons in a research setting (Supplemental Figure 1A‐1F). Data for each combination of characteristics are shown in Supplemental Table 7

Note: Green colors indicate lower frequencies of amyloid positivity, and red colors indicate higher frequencies of amyloid positivity. Table columns contain the main characteristics age, setting, and APOE ε4 carriership, and rows contain additional characteristics that were associated with lower or higher frequency of amyloid positivity. Results are displayed for age 60, 70, and 80. Some of the combinations of characteristics were not available for persons age60, 70, or 80 and a slightly younger or older age was selected in 9% of the combinations (range from 3 years younger to 1 year older). *P < .05 or **P < .001 for difference between row characteristic (lower education vs higher education, without vs with informant confirmation of complaints, without vs with complaints specific to memory, without vs with complaints specific to attention/concentration, without vs with feelings of worse performance, without vs with depressive symptoms, respectively).
