Objective:
The Biber Figure Learning Test (BFLT) is a serial figure learning assessment previously been shown to be sensitive to various biomarkers of the aging brain. BFLT is an extensive assessment requiring about 30 minutes for administration. In this study, we investigated BFLT’s associations with subjective cognitive decline (SCD), an early marker for preclinical Alzheimer’s Disease (AD), and examined whether alternative BFLT indices could be utilized to considerably shorten the length of assessment without decreasing its sensitivity to SCD.
Participants and Methods:Participants were 50 cognitively normal older adults (8% Hispanic, 92% Non-Hispanic; 78% White, 16% Black; 64% female; mean age =72.7 (SD =6.2); mean education =17.05 (SD =2.09)). SCD was measured using a 20-item age-anchored dichotomous questionnaire that assessed complaints of cognitive functioning, and the BFLT was administered in full. Pearson correlations were conducted between SCD and BFLT scores including: Trial 1 Learning (T1), Trials 1 to 2 Total Learning (T1T2), Trials 1 to 3 Total Learning (T1T3), Trials 1 to 5 Total Learning (Total Learning), Immediate Recall, Delayed Recall, Proactive Interference (Trial B – Trial 1), Retroactive Interference (Immediate Recall – Trial 5), and Total Discrimination (calculated as [Recognition Total Correct + 0.5]/16) − ([Total False Alarms + 0.5]/31]). A Fishers Exact Test was utilized to compare the correlational strength between SCD and each of the BFLT scores. Lastly, demographically adjusted (age, gender, and education) regression models were conducted to examine SCD as an individual predictor for the various BFLT scores.
Results:SCD was negatively associated with BFLT T1 (r =-0.406, p =0.003), T1T2 (r =-0.331, p =0.019), T1T3 (r =-0.323, p =0.022), Total Learning (r =-0.283, p =0.046), Immediate Recall (r =-0.322, p =0.023), Delayed Recall (r =-0.318, p =0.025), and Retroactive Interference (r =-0.388, p =0.005) and positively associated with Proactive Interference (r =0.308, p =0.029). There was no significant difference in correlational strength between any of these BFLT scores and SCD. Adjusting for demographics, SCD predicted Immediate Recall (B =-0.273, p =0.029), Total Learning (B =- 0.253, p =0.040), T1 (B =-0.412, p =0.002), T1T2 (B =-0.326, p =0.010), T1T3 (B =-0.299, p =0.017), Proactive Interference (B =0.292, p =0.050), and Retroactive Interference (B =- 0.330, p =0.025).
Conclusions:Eight of the nine assessed BFLT scores were strongly correlated with age-anchored SCD and age-anchored SCD predicted seven of the nine assessed BFLT indices when adjusted for demographics. Although additional work is needed, these findings suggest SCD’s sensitivity to changes in visuospatial learning and memory, supporting its use as an early marker for preclinical AD. Likewise, our results suggest that an abbreviated version of the BFLT could be utilized that shortens testing time and reduces participant fatigue without a decrease in clinical relevance. Through ongoing longitudinal work, we hope to further disentangle the relationship between SCD and visuospatial learning and memory as measured through the BFTL and to examine how associations between SCD and the BFLT assessment change over time.

Objective:
Subjective Cognitive Decline (SCD) is the self-reported experience of one’s own declining cognition prior to objective impairment on clinical neuropsychological testing. While SCD is a promising marker of preclinical Alzheimer’s disease (AD), information is needed to determine which cognitive complaints reflect typical aging versus prodromal degenerative disease. The objective of the current study was to examine the extent to which specific cognitive complaints were associated with two clinical outcomes including: 1) lower performance on cognitive tasks sensitive to preclinical AD; and 2) seeking help (i.e., medical attention) for cognitive difficulties.
Participants and Methods:The current sample consisted of 175 healthy older adults (56 Male, 119 Female), aged 51 to 90 (M=72.67, SD=7.12) with a mean education of 16 years (SD=2.3 years) who performed > -1.5 SD on clinical neuropsychological testing. 26.8% of the sample self-reported as race/ethnic minorities (e.g., Hispanic or Non-Hispanic, Black, Asian, Other.) Participants completed a 20-item SCD questionnaire assessing perceived cognitive difficulties in comparison to same aged peers, and tests shown to be sensitive to preclinical AD including the Face Name Associative Learning Test and the Loewenstein-Acevedo Scales for Semantic Interference and Learning. Participants were coded as having sought help for SCD (39%) if they entered the current study from a clinical referral source, OR if they entered through a non-clinical referral stream but indicated that they had previously seen a doctor specifically for memory concerns or spoken to their doctor about memory concerns. Chi square tests were used to examine relationships between SCD item endorsement and help-seeking; ANOVAs were used to the extent to which item endorsement was associated with performance on cognitive tests. Results were considered significant at p < .05.
Results:Three SCD items were associated with both lower cognitive test scores and having sought help for SCD (p values ranged from < .001 to .02). Items included difficulty remembering the date or day of the week and remembering a few shopping items without a list. One non-memory item was also associated with both outcomes including difficulty thinking ahead. In contrast, six items were not related to either outcome of interest. Such items included difficulty remembering appointments, remembering where you put things like keys, following a map to a new location, doing two things at once, understanding what you read, or understanding what people say to you. The remaining eleven items explore the extent to which selective associations exist with either help-seeking or cognitive performance.
Conclusions:Patients and clinicians alike are often unsure about which cognitive difficulties are typical for aging and which may be the cause for further workup. Current results suggest that certain complaints among cognitively healthy older adults may be cause for more thorough evaluation or monitoring. These complaints include specific memory and nonmemory concerns. Future work is needed to determine if these complaints predict future cognitive decline or conversion to Mild Cognitive Impairment.

Objective:
Alzheimer’s disease (AD) is expected to affect over 7 million older Americans by 2025. Development of fast and inexpensive screening measures for routine screening is critical for identifying those suffering from the earliest stages of AD including Mild Cognitive Impairment (MCI) and Subjective Cognitive Decline (SCD). Here we assess the validity and utility of a brief, 5-item SCD screener and its associations with neuropsychological performance as compared to an existing objective cognitive screener, the Mini Mental Status Exam (MMSE).
Participants and Methods:Development: A brief, 5-item SCD questionnaire was developed based on a more extensive 20-item version previously validated (Chapman et al. 2021). Participants: 27 cognitively diverse (MCI and cognitively normal) community dwelling older adults were recruited for this study. Mean age: 71.9 ± 7. Inclusion criteria include memory concerns. Exclusion criteria include no previous diagnoses of neurodegenerative diseases and/or major stroke. Administration: Participants completed a brief, 5-item SCD screener along with cognitive testing including the MMSE and a clinically validated list-learning test, the Selective Reminding Test (SRT). Statistical Methods: Spearman 2-tailed correlations were conducted to assess the relationship between the two screening measures, and their relationships to the SRT. Outcome measures on the SRT included total recall (max: 72) and delayed recall (max: 12). All cognitive measures were demographically adjusted with normative data.
Results:The mean total for the SCD screener was 2.1 ±1.1, and the mean MMSE score was 29.2 ± 1.2. The SCD screener was associated with MMSE scores (r= -.39, p= .043), SRT Total Recall (r= -.43, p= .024) and Delayed Recall (r=-.42, p=.031) measures. MMSE scores did not associate with either SRT outcome (p>.05).
Conclusions:Results support the utility and validity of a brief subjective cognitive decline screener for identifying those who may be experiencing memory dysfunction. The brief SCD screener outperformed the MMSE, an existing and widely used objective screening measure. Associations between the SCD screener and SRT outcomes support the validity and utility of the brief screener and recapitulate previous findings with the more extensive version of the SCD questionnaire (Chapman et al. 2021). Ongoing research is focusing on the utility of the screener in frontline clinical settings and translation of the screener into Spanish.

Objective:
Subjective Cognitive Decline (SCD), the perception of deteriorating cognition in the absence of apparent impairment on objective testing, has gained momentum in recent literature as a risk marker for AD. Traditional neuropsychological assessments, while typically inclusive of a word list learning task, often do not include a comparable figure learning task. Growing evidence suggests that nonverbal assessments may be particularly sensitive to the earliest cognitive changes associated with Alzheimer’s disease. The Biber Figure Learning Test (BFLT), a visuospatial analogue to verbal list learning tasks, has been shown to associate with brain-based biomarkers of Alzheimer’s disease (AD; hippocampal volume, amyloid load). This study investigates the utility of the BFLT in capturing SCD above and beyond other cognitive measures sensitive to AD progression.
Participants and Methods:50 community-dwelling, cognitively normal individuals (78% White, 16% Black, 6% Other; 92% Non-Hispanic; 64% Female; Education M=17.1, SD=2.1; Age M=72.7, SD=6.2) participated in a study of SCD. All participants performed >-1.5 SD on clinical neuropsychological testing including a word list learning task. SCD was assessed using a 20-item scale querying individuals’ perception of difficulty across a range of memory and non-memory abilities in relation to others of the same age. Participants completed the BFLT, Loewenstein-Acevedo Scales of Semantic Interference and Learning (LASSI-L), Short-Term Memory Binding (STMB), and Face-Name Associative Memory Exam (FNAME), previously established as being sensitive to pre-clinical AD, were examined as predictors of SCD. A multiple regression adjusted for demographics (age, gender, education) was used to investigate the extent to which BFLT Trial 1 (T1) predicted SCD above and beyond these other cognitive measures sensitive to AD progression. Trial 1 of the BFLT was used based on a separate abstract examining which BFLT score was most highly associated with SCD (Kann et al., pending acceptance).
Results:Adjusting for demographics, the present model accounts for 42% of the variance in SCD, while Biber T1 alone accounts for 20% and is the only significant individual predictor of SCD (β=-0.55, p=0.004). In contrast, other variables in the model independently accounted for less than 1% to 4% each (age β=-0.23, p=0.15; gender β=-0.15, p=0.34; education β=0.06, p=0.66; LASSI-L β=-0.11, p=0.55; STMB β=-0.03, p=0.85; FNAME β=-0.10, p=0.64).
Conclusions:The present study demonstrates the usefulness of the first learning trial of the BFLT as an independent predictor of SCD above and beyond other verbal and nonverbal measures sensitive to AD pathology. It also highlights the value of including even one trial of figure learning (< 5 minutes) in both clinical and research assessments seeking to capture cognitive changes which may be the earliest indicators of a neurodegenerative process. Ongoing longitudinal research is examining the predictive utility of the BFLT for future cognitive decline and transition to Mild Cognitive Impairment. Further research should explore the association between Biber T1, specifically, and neuropathological biomarkers of AD to further establish its utility as a portent of AD.

Objective:
Historically, psychiatric conditions and neurodegenerative diseases have been considered differential diagnoses in older adults with cognitive impairment. However, recent evidence has shown that neuropsychiatric symptoms may be prodromal for neurodegenerative disease. Subjective Cognitive Decline (SCD) is a potential marker for pre-clinical Alzheimer’s Disease (AD) that is frequently related to mood disturbances. Delineating the relationship between neuropsychiatric symptoms, SCD, and cognitive impairment will help to define both the independent and combined utility of SCD and neuropsychiatric symptoms as markers of preclinical AD. This abstract uses the DSM-5 Cross-Cutting Measure (DSM-5 CC), a novel comprehensive screening tool for psychiatric symptoms, to examine the relationship between objective and subjective measures of cognition as they relate to neuropsychiatric symptoms.
Participants and Methods:27 community dwelling, cognitively diverse older adults (78% female, mean age 71.9 ± 7) were enrolled in the Concerns about Memory Problems (CAMP) study. Inclusion criteria included the expressed concern about memory functioning by participants on a 5-item screener, while exclusion criteria were defined as previous diagnosis of neurodegenerative diseases and/or major stroke. All participants completed neuropsychological testing and study surveys including the DSM-5 CC. Participants completed Level 1 and all Level 2 (L2) forms of the DSM-5 CC. Spearman two-tailed non-parametric correlations and independent samples t-tests were conducted to examine the relationship between the DSM-5 CC and the 5-item subjective cognition screener, as well as the DSM-5 CC and objective cognition results.
Results:Subjective measures of cognition, as measured by answers to the 5-item screening measure, were significantly associated with DSM-5 CC measures. Question 1 on the SCD screener which asks, “Compared to others your age, do you have difficulty with memory or thinking abilities?” was associated with anger (p=.033) and depression (p=.018) L2 forms. Question 3, “Do any difficulties with memory or thinking abilities make it difficult for you to do things in daily life?)” was associated with the L2 forms for somatic symptoms (p=.016) and repetitive thoughts and behaviors (p<.001). Objective measures of cognition from neuropsychological testing also correlated with DSM-5 CC sub-scores. Digits Backwards Length (DBL) correlated with DSM-5 CC Level 1 Sum (r= -.57, p=.002). DBL (r=-.59 p=.001) and Digits Backwards Total Correct (DBTC) (r=-.47, p=.013) associated with somatic symptoms L2 and sleep L2 (DBL: r=,-.45 p=.019; DBTC: r=-.39, p=.044). Category Naming (animals) was also associated with anxiety L2 (r=-.42, p=.030).
Conclusions:Subjective and objective measures of cognition were each related to sub-scores of the DSM-5 CC. Interestingly, the associations were largely non-overlapping. These results highlight the importance of considering a wide range of neuropsychiatric symptoms in the assessment of SCD and cognitive impairment. Findings contribute to the growing body of literature suggesting that neuropsychiatric symptoms should be studied in conjunction with cognitive symptoms among older adults as co-occurring phenomena. Future directions will need to include longitudinal studies that can examine the prodromal nature of SCD and neuropsychiatric symptoms for Alzheimer’s and other neurodegenerative disorders.

Objective:
Subjective cognitive decline (SCD) is increasingly being considered one of the earliest clinical signs of Alzheimer’s Disease (AD). Certain characteristics of early life, such as childhood socioeconomic status (SES), have been associated with late life cognitive performance. Here we examine the extent to which childhood SES predicts SCD.
Participants and Methods:The current sample consisted of 55 healthy older adults (17 Male, 39 Female), aged 51 to 88 (M=73.14, SD=6.23) with a mean education of 16 years (SD=2.1 years). 21.5% of the sample self-reported as race/ethnic minorities (e.g., Hispanic or Non-Hispanic African American, Asian, Other.) Participants completed a 20-item SCD questionnaire assessing perceived cognitive difficulties in comparison to same aged peers, and objective cognitive testing. Childhood SES was assessed using two items. The first item asked the participant to utilize a modified MacArthur Scale of Subjective Social Status to identify where on the ladder they felt their family would have been placed during their childhood relative to others in the United States. This ladder has 10 rungs, with rung 1 associated with being the “worst off” and rung 10 associated with being the “best off”. The second item asked the participant to rate their family’s difficulty paying bills during their childhood. Linear regression models were used to examine the extent to which childhood SES predicted SCD. Models were adjusted for education, referral source (clinical versus non-clinical), and objective cognitive testing. Age and gender were not associated with childhood SES or SCD, and as a result were not adjusted for in these models.
Results:On the MacArthur Scale, 20% of participants placed their family at rung 5, 38.2% placed their families at a rung lower than 5, and 41.8% placed their family at a rung higher than 5. When rating the difficulty their family faced paying bills, 3.6% of participants responded “extremely difficult”, 16.4% responded “very difficult”, 20% responded “somewhat difficult”, 23.6% responded “slightly difficult”, and 36.4% responded “not difficult”. Linear regression models revealed a significant effect of childhood SES on SCD (β=-.29, p=.045, SE=.90; β=-.35, p=.015, SE=1.68).
Conclusions:Childhood SES, measured by subjective social status and family’s difficulty paying the bills in childhood, was predictive of SCD in this study of cognitively healthy adults. This result highlights another characteristic of early life that may shape the path of cognitive aging. The predictive utility of childhood SES for SCD may also provide clinicians and researchers with further insight into the populations that may be more susceptible to experiencing SCD in later life. Future studies should utilize a larger sample size among a population with a greater range of childhood SES, to most accurately capture the effectiveness of childhood SES to predict SCD.

Objective:
Research has indicated that racial and ethnic minoritized groups in the United States are disproportionately affected by dementia (e.g., Alzheimer’s disease), and seek help (HS) later in the disease course, if at all. It has also been posited that individuals from different ethno-racial groups have divergent perceptions of the aging process, which may influence HS. These disparities warrant tailored preventive efforts to encourage identification of factors which contribute to HS to enable earlier psychoeducation and enhanced access to resources. The factors which influence HS may differ across ethnoracial groups. Here we examine the relative influence of subjective cognitive decline (SCD), a risk factor for AD, and aging perceptions to HS in these groups.
Participants and Methods:The current sample consisted of 161 healthy older adults (51 Male, 110 Female), aged 51 to 92 (M=73.43, SD=6.85) with a mean education of 16 years (SD=2.3 years) who performed > -1.5 SD on clinical neuropsychological testing. 26.7% of the sample self-reported as race/ethnic minorities (e.g., Hispanic or Non-Hispanic African American, Asian, Other.) Participants completed a 20-item SCD questionnaire assessing perceived cognitive difficulties in comparison to same aged peers, in addition to measures assessing HS behavior, (e.g., Have you gone to the doctor specifically for memory concerns?), and aging perceptions (e.g., older adulthood group identification, explicit stereotypes, essentialism). Point biserial correlations examined relationships between SCD, HS and aging perceptions, and multinomial logistic regressions examined the contribution of SCD and aging perceptions to HS across majority (White) and minoritized groups (Non-White participants).
Results:In bivariate analyses of the White participant group, HS was associated with SCD (r=0.43, p<0.001) and age group identification (r=0.27, p<0.01), and the latter were also associated (r=-0.19, p<0.05). The logistic regression model correctly classified 86% of participants (same as null), explaining a relatively small proportion of variance in HS, Snell R2 = 0.09, Nagelkerke’s R2 = 0.16. Age group identification was not associated with HS (b=-0.02, SE=0.26, p=0.94, 95% CI [0.59, 1.63] but SCD was (p=0.04). In the non-White group (n=42), bivariate analyses showed that HS was associated with essentialism (r=-0.41, p<0.01; belief aging as a fixed and inevitable process)) and explicit stereotypes (r=-0.42, p<0.01) but not with SCD (r=0.21, p=0.19). SCD was also associated with essentialism (p=-0.32, p<0.05), stereotypes (p=0.32, p<0.05), and age group identification (r=0.38, p<0.01). The regression model correctly classified 88.9% of participants (same as null); neither SCD (p=0.39), explicit stereotypes (p=0.43), essentialism (p=0.72), nor age group identification (p=0.62) contributed to HS when all were considered.
Conclusions:When both SCD and age perceptions are examined together as predictors of HS, SCD alone predicts HS in the majority group. Neither construct predicts HS in the minoritized group—despite significant bivariate associations between HS, aging perceptions and SCD that varied across ethno-racial groups. Findings illustrate that SCD and aging perceptions may contribute differently to HS across ethno-racial groups in the US, and as such may indicate different priorities when implementing HS tools (e.g., screeners for detection of cognitive impairment). Ongoing work is addressing illness perceptions, another key barrier in HS in these groups to further inform on tailoring of services.

Objective:
An individual with dementia suffers from cognitive decline affecting not only memory but at least one of the other domains, such as personality, praxis, abstract thought, language, executive functioning, attention, and social skills. Further, the severity of the decline must be significant enough to interfere with daily functions. It is currently unknown whether any of the causes of dementia can be cured. Many challenges confront patients and their families, including a lack of knowledge about dementia and associated treatments; therefore, it is essential to study illness perception regarding dementia-related symptoms in order to improve psychoeducation and lower barriers to seeking assistance. How individuals perceive and make sense of early dementia symptoms can significantly impact their help-seeking behaviors (HS). Exploring illness-perception regarding dementia-related symptoms may contribute to the development of strategies for increasing HS, early diagnosis, and intervention. The objective of this study is to describe aspects of illness perception in cognitively healthy older adults and examine potential correlations with demographic variables, including age, gender, and education.
Participants and Methods:The cohort comprised 55 cognitively healthy older adults enrolled in a study examining Subjective Cognitive Decline. All participants performed > -1.5 SD on clinical neuropsychological testing. Participants were 70% female and 30% male; and self-identified as White = 78%, Black = 16%, Asian = 2%, Other = 4% and Non-Hispanic = 98%. Participants read a short vignette describing a person experiencing significant memory issues representative of an individual with mild dementia and answered seven follow-up questions regarding the cause of memory problems, the likely course of memory problems, and potential treatments for memory problems. Chi-square analyses examined the endorsement of items in relation to age, gender, and education.
Results:When asked about the likely cause of memory problems, 65% of participants endorsed neurologic disease, 53% of participants endorsed normal aging, 26% endorsed stress, 25% endorsed genes, 4% endorsed fate/luck, and 16% endorsed "Don't know" for likely cause of symptoms. 64% of participants responded "will get worse", 18% "will go up and down", 16% "Don't know", and 2% "Other" in response to the progression of memory problems over time. For "Can he do anything to help [memory problems]?", only 2% responded "No" while 76% responded "Yes" and 22% endorsed "Don't know". On a follow-up question regarding ways an individual could improve his cognitive difficulties, 78% "Social Engagement", 73% "Exercise", 64% endorsed "Medication", 48% "Diet", 42% Psychological Treatment", 29% "Rehabilitation", 9%" Don't know" and 15% "Other." Lastly, 58% of participants reported "Independence", 33% "Identity," 4% "Friends," 4% "Respect," and 1% "Don't know" for things he may risk losing due to memory problems. Age, gender, and education were not associated with any of the above responses (p > .05).
Conclusions:Older adults demonstrate a range of ideas about the cause, course, and potential treatment for memory disorders. Understanding how and what factors impact illness perception is a pivotal step in improving illness perception and ultimately narrowing the gap in health disparities and HS. Further work in a large demographically representative sample is needed on illness perception and how socioeconomic factors, ethnicity, and other mediators interact with its impact on HS for dementia-related symptoms.

Objective:
The COVID-19 pandemic increased utilization of remote assessment to allow clinicians and researchers to continue valuable work while maintaining quarantine guidelines. With guidelines relaxing, researchers have returned to in-person assessment. Information is needed regarding the effect of remote assessments on test-retest reliability. COGNET, a longitudinal study of cognition in participants with essential tremor, transitioned from in-person to remote assessments during the pandemic, and has now returned to in-person assessment. The current study investigates the extent to which remote assessment affected test-retest reliability across a range of neuropsychological assessments administered in COGNET.
Participants and Methods:Participants included 27 older adults enrolled in COGNET (mean age=75.0 (9.1), education=16.2 (2.6), 67% female, and 100% white). Memory tests included: California Verbal Learning Test II, Logical Memory subtest of the Wechsler Memory Scales - Revised, and Verbal Paired? Associates. Executive function tests included: Digit Span Backwards and the Delis-Kaplan Executive Function System subtests of Verbal Fluency, Sorting, and Color-Word. Attention tests included Oral Symbol Digit Modalities Test and Digit Span Forward. Language was assessed with the Boston Naming Test. Intraclass correlation coefficients (ICCs) were calculated to examine test-retest reliability of InPerson to In-Person visits (P-P), and combination visits (e.g., In-Person to Remote (PR), and Remote to In-Person (R-P)). Following Koo & Li (2016), ICCs were interpreted as: >.90 excellent, .75-.90 good, .50-.74 moderate, and <.50 poor reliability. The Feldt approach was used to compare ICCs from P-P visits against ICCs calculated for combination visits (P-R or R-P), with the test statistic compared to an F distribution.
Results:ICCs for person-to-person assessment ranged from .51 to .89. Memory test ICCs ranged from moderate to good (.51 to .80). Executive function test ICCs ranged from moderate to good (.55 to .89). The attention domain had moderate ICCs (.67 - .68). Language ICC was moderate (.70). ICCs for person-to-remote assessment ranged from .42 to .89. Memory tests ranged from moderate to good ICCs (.59 to .83). Executive function tests ranged from poor to good ICCs (.42 to .89). Attention ICCs were moderate to good (.55 to .79). The Language ICC was moderate (.72). ICCs for remote-to-person ranged from .48 to 86. Memory ICCs ranged from moderate to good (.59 to .86). Executive function ICCs ranged from poor to good (.48 to .83). Attention ICCs were moderate to good (.56 to .79). The Language ICC was good (.78). The only test for which an ICC from a combination visit was significantly lower than a person to person visit was Digit Span Backwards.
Conclusions:Test-retest reliability was moderate or better for all P-P assessments, consistent with the known psychometrics of these tests. Only one test of executive function showed lower reliability when remote assessment was introduced. From a broad standpoint, current results suggest that remote administration of neuropsychological tests can be used as a reliable substitute for in-person assessment for many measures, and suggest that caution be used when interpreting any change in Digit Span Backwards across person and remote assessments.
