Applicability of the Telephone Interview for Cognitive Status (Modified) in a community sample with low education level: association with an extensive neuropsychological battery

Tele-Global Examination of Mental State (Tele-GEMS): an open tool for the remote neuropsychological screening

Tele-neuropsychology, i.e., the application of remote audio-visual technologies to neuropsychological evaluation or rehabilitation, has become increasingly popular and widespread during and after the COVID-19 pandemic. New tools with updated normative data and appropriate methodological developments are necessary. We present Tele-GEMS, a telephone-based cognitive screening developed on N = 601 Italian participants. It yields a global score tapping on orientation, memory, spatial representation, language, and pragmatic abilities. Its administration lasts about 10 min. Clinical cut-offs are provided, accounting for demographic variables (age, education, and sex) and also for a comprehensive index taking into account cognitively stimulating life experiences that can build up a cognitive reserve. Tele-GEMS shows good internal consistency and a good inter-rater agreement. The test includes the thresholds for estimating a significant change after repeated measurements. Tele-GEMS has a good construct validity as assessed with MoCA and a suitable criterion validity assessed with its in-person version (GEMS). All the materials and the instructions, including scripts and an online Application for the automatic calculation of cut-offs, are accessible on OSF at https://osf.io/t3bma/ under a Creative Commons license.

Using network analysis to validate domains of the modified telephone interview for cognitive status

BACKGROUND

The modified Telephone Interview for Cognitive Status (TICS-M) is a widely used tool for assessing global cognitive functions and screening for cognitive impairments. The tool was conceptualised to capture various cognitive domains, but the validity of such domains has not been investigated against comprehensive neuropsychological assessments tools. Therefore, this study aimed to explore the associations between the TICS-M domains and neuropsychological domains to evaluate the validity of the TICS-M domains using network analysis.

MATERIALS AND METHODS

A longitudinal research design was used with a large sample of older adults (aged above 70 years; n = 1037 at the baseline assessment) who completed the TICS-M and comprehensive neuropsychological assessments biennially. We applied network analysis to identify unique links between the TICS-M domains and neuropsychological test scores.

RESULTS

At baseline, there were weak internal links between the TICS-M domains. The TICS-M memory and language domains were significantly related to their corresponding neuropsychological domains. The TICS-M attention domain had significant associations with executive function and visuospatial abilities. The TICS-M orientation domain was not significantly associated with any of the five neuropsychological domains. Despite an attrition of almost 50% at wave four, weak internal links between the TICS-M domains and most associations between TICS-M and neuropsychological domains that were found initially, remained stable at least over two waves within the 6-year period.

CONCLUSIONS

This study supports the overall structural validity of the TICS-M screener in assessing enduring global cognitive function. However, separate TICS-M cognitive domains should not be considered equivalent to the analogous neuropsychological domains.

Diagnostic test accuracy of remote, multidomain cognitive assessment (telephone and video call) for dementia

BACKGROUND

Remote cognitive assessments are increasingly needed to assist in the detection of cognitive disorders, but the diagnostic accuracy of telephone- and video-based cognitive screening remains unclear.

OBJECTIVES

To assess the test accuracy of any multidomain cognitive test delivered remotely for the diagnosis of any form of dementia. To assess for potential differences in cognitive test scoring when using a remote platform, and where a remote screener was compared to the equivalent face-to-face test.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group Specialized Register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, LILACS, and ClinicalTrials.gov (www.

CLINICALTRIALS

gov/) databases on 2 June 2021. We performed forward and backward searching of included citations.

SELECTION CRITERIA

We included cross-sectional studies, where a remote, multidomain assessment was administered alongside a clinical diagnosis of dementia or equivalent face-to-face test.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data; a third review author moderated disagreements. Our primary analysis was the accuracy of remote assessments against a clinical diagnosis of dementia. Where data were available, we reported test accuracy as sensitivity and specificity. We did not perform quantitative meta-analysis as there were too few studies at individual test level. For those studies comparing remote versus in-person use of an equivalent screening test, if data allowed, we described correlations, reliability, differences in scores and the proportion classified as having cognitive impairment for each test.

MAIN RESULTS

The review contains 31 studies (19 differing tests, 3075 participants), of which seven studies (six telephone, one video call, 756 participants) were relevant to our primary objective of describing test accuracy against a clinical diagnosis of dementia. All studies were at unclear or high risk of bias in at least one domain, but were low risk in applicability to the review question. Overall, sensitivity of remote tools varied with values between 26% and 100%, and specificity between 65% and 100%, with no clearly superior test. Across the 24 papers comparing equivalent remote and in-person tests (14 telephone, 10 video call), agreement between tests was good, but rarely perfect (correlation coefficient range: 0.48 to 0.98).

AUTHORS' CONCLUSIONS

Despite the common and increasing use of remote cognitive assessment, supporting evidence on test accuracy is limited. Available data do not allow us to suggest a preferred test. Remote testing is complex, and this is reflected in the heterogeneity seen in tests used, their application, and their analysis. More research is needed to describe accuracy of contemporary approaches to remote cognitive assessment. While data comparing remote and in-person use of a test were reassuring, thresholds and scoring rules derived from in-person testing may not be applicable when the equivalent test is adapted for remote use.

Performance validity testing via telehealth and failure rate in veterans with moderate-to-severe traumatic brain injury: A veterans affairs TBI model systems study

BACKGROUND

The COVID-19 pandemic has led to increased utilization of teleneuropsychology (TeleNP) services. Unfortunately, investigations of performance validity tests (PVT) delivered via TeleNP are sparse.

OBJECTIVE

The purpose of this study was to examine the specificity of the Reliable Digit Span (RDS) and 21-item test administered via telephoneMETHOD:Participants were 51 veterans with moderate-to-severe traumatic brain injury (TBI). All participants completed the RDS and 21-item test in the context of a larger TeleNP battery. Specificity rates were examined across multiple cutoffs for both PVTs.

RESULTS

Consistent with research employing traditional face-to-face neuropsychological evaluations, both PVTs maintained adequate specificity (i.e., >  90%) across previously established cutoffs. Specifically, defining performance invalidity as RDS <  7 or 21-item test forced choice total correct <  11 led to <  10%false positive classification errors.

CONCLUSIONS

Findings add to the limited body of research examining and provide preliminary support for the use of the RDS and 21-item test in TeleNP via telephone. Both measures maintained adequate specificity in veterans with moderate-to-severe TBI. Future investigations including clinical or experimental "feigners" in a counter-balanced cross-over design (i.e., face-to-face vs. TeleNP) are recommended.

MADRID+90 study on factors associated with longevity: Study design and preliminary data

The progressive aging of the population represents a challenge for society. In particular, a strong increase in the number of people over 90 is expected in the next two decades. As this phenomenon will lead to an increase in illness and age-related dependency, the study of long-lived people represents an opportunity to explore which lifestyle factors are associated with healthy aging and which with the emergence of age-related diseases, especially Alzheimer's type dementia. The project "Factors associated with healthy and pathologically aging in a sample of elderly people over 90 in the city of Madrid" (MADRID+90) brings together a multidisciplinary research team in neurodegenerative diseases that includes experts in epidemiology, neurology, neuropsychology, neuroimaging and computational neuroscience. In the first phase of the project, a stratified random sampling was carried out according to the census of the city of Madrid followed by a survey conducted on 191 people aged 90 and over. This survey gathered information on demographics, clinical data, lifestyles and cognitive status. Here, the main results of that survey are showed. The second phase of the project aims to characterize individual trajectories in the course of either healthy and pathological aging, from a group of 50 subjects over 90 who will undergo a comprehensive clinical examination comprised of neurological and cognitive testing, MRI and EEG. The ultimate goal of the project is to characterize the biophysical and clinical profiles of a population that tends to receive little attention in the literature. A better understanding of the rapidly increasing group of nonagenarians will also help to design new policies that minimize the impact and future social and economic consequences of rapidly aging societies.

Cognitive Assessment via Telephone: A Scoping Review of Instruments

OBJECTIVE

Telephone-based cognitive assessment (TBCA) has long been studied but less widely adopted in routine neuropsychological practice. Increased interest in remote neuropsychological assessment techniques in the face of the coronavirus 2019 (COVID-19) pandemic warrants an updated review of relevant remote assessment literature. While recent reviews of videoconference-based neuropsychological applications have been published, no updated compilation of empirical TBCA research has been completed. Therefore, this scoping review offers relevant empirical research to inform clinical decision-making specific to teleneuropsychology.

METHOD

Peer-reviewed studies addressing TBCA were included. Broad search terms were related to telephone, cognitive, or neuropsychological assessment and screening. After systematic searching of the PubMed and EBSCO databases, 139 relevant articles were retained.

RESULTS

In total, 17 unique cognitive screening measures, 20 cognitive batteries, and 6 single-task measures were identified as being developed or adapted specifically for telephone administration. Tables summarizing the identified cognitive assessments, information on diagnostic accuracy, and comparisons to face-to-face cognitive assessment are included in supplementary materials.

CONCLUSIONS

Overall, literature suggests that TBCA is a viable modality for identifying cognitive impairment in various populations. However, the mode of assessment selected clinically should reflect an understanding of the purpose, evidence, and limitations for various tests and populations. Most identified measures were developed for research application to support gross cognitive characterization and to help determine when more comprehensive testing was needed. While TBCA is not meant to replace gold-standard, face-to-face evaluation, if appropriately utilized, it can expand scope of practice, particularly when barriers to standard neuropsychological assessment occur.

Prevalence and correlates of dementia and mild cognitive impairment classified with different versions of the modified Telephone Interview for Cognitive Status (TICS-m)

OBJECTIVES

The modified Telephone Interview for Cognitive Status (TICS-m) is an efficient and cost-effective screening instrument of dementia, but there is less support for its utility in the detection of mild cognitive impairment (MCI). We undertook a comprehensive evaluation of the utility of different TICS-m versions with or without an education-adjusted scoring method to classify dementia and MCI in a large population-based sample.

METHODS

Cross-sectional assessment of cognition (TICS-m), depressive symptoms (CES-D), and apolipoprotein E (APOE) ε4 status was performed on 1772 older adults (aged 71-78 y, education 5-16 y, 50% female) from the population-based older Finnish Twin Cohort. TICS-m classification methods with and without education adjustment were used to classify individuals with normal cognition, MCI, or dementia.

RESULTS

The prevalence of dementia and MCI varied between education-adjusted (dementia = 3.7%, MCI = 9.3%) and unadjusted classifications (dementia = 8.5%-11%, MCI = 22.3%-41.3%). APOE ε4 status was associated with dementia irrespective of education adjustment, but with MCI only when education adjustment was used. Regardless of the version, poorer continuous TICS-m scores were associated with higher age, lower education, more depressive symptoms, male sex, and being an APOE ε4 carrier.

CONCLUSIONS

We showed that demographic factors, APOE ε4 status, and depressive symptoms were similarly related to continuous TICS-m scores and dementia classifications with different versions. However, education-adjusted classification resulted in a lower prevalence of dementia and MCI and in a higher proportion of APOE ε4 allele carriers among those identified as having MCI. Our results support the use of education-adjusted classification especially in the context of MCI.

Attention/memory complaint is correlated with motor speech disorder in Parkinson's disease

BACKGROUND

The mechanisms underlying the online modulation of motor speech in Parkinson's disease (PD) have not been determined. Moreover, medical and rehabilitation interventions for PD-associated motor speech disorder (MSD) have a poor long-term prognosis.

METHODS

To compare risk factors in PD patients with MSD to those without MSD (non-MSD) and determine predictive independent risk factors correlated with the MSD phenotype, we enrolled 314 PD patients, including 250 with and 64 without MSD. We compared demographic, characteristic data, as well as PD-associated evaluations between the MSD group and non-MSD group.

RESULTS

Univariate analysis showed that demographic characteristics, including occupation, educational level, monthly income and speaking background; clinical characteristics, including lesions in the frontal and temporal lobes, and concurrent dysphagia; and PD-associated evaluations, including the activity of daily living (ADL) score, non-motor symptoms scale (NMSS) domain 4 score (perceptual problem), and NMSS domain 5 score (attention/memory) were all significantly different between the MSD and non-MSD group (all P < 0.05). Multivariate logistic regression analysis showed that educational level, frontal lesions, and NMSS domain 5 score (attention/memory) were independent risk factors for PD-associated MSD (all P < 0.005).

CONCLUSIONS

We determined an association between MSD phenotype and cognitive impairment, reflected by low-level education and related clinical profiles. Moreover, attention and memory dysfunction may play key roles in the progression of MSD in PD patients. Further studies are required to detail the mechanism underlying abnormal speech motor modulation in PD patients. Early cognitive intervention may enhance rehabilitation management and motor speech function in patients with PD-associated MSD.

The Association Between Lipoproteins, Disability, and Physical Function Among Older Costa Rican Adults

OBJECTIVE

To examine the relationship between total cholesterol (TC), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C) with disability and physical performance.

METHOD

Wave 1 data were from Costa Rican Longevity and Healthy Aging Study ( n = 2,827). Lipoprotein profiles were measured using blood samples. Disability and physical functioning were measured with activities of daily living/instrumental activities of daily living (ADLs/IADLs) and objective assessment of physical performance.

RESULTS

Lower HDL-C was associated with greater ADL disability, and lower TC with longer time to pick-a-pencil and Time-Up-Go (TUG) test. Age interacted between (a) TG and lung function, chair stands, and pick-a-pencil, and (b) HDL-C and TUG. Stratification showed lower TG and longer time picking up a pencil only for those above 84 years. Based on significant interactions with sex, lower TC was associated with slower chair stand time in women and higher HDL-C with slower chair stand time in men.

DISCUSSION

Lower levels of lipoproteins may suggest worse physical function, but the association may differ by sex.

When New Technology is an Answer for Old Problems: The Use of Videoconferencing in Cognitive Aging Assessment

People living with cognitive impairment and dementia require regular screening of their symptomatology and needs. Brief cognitive screening is crucial for assessing these conditions. Such screening can give health professionals a snapshot of the patient's cognitive abilities and help in their monitoring and adaptation. An appropriate administration of brief cognitive screening using telemedicine technology, such as videoconference, can improve access to care and treatment planning. Moreover, the burden that rural and underserved communities often suffer because of limited access to specialty mental health services is also of concern. Herein, in this review, we describe the existing and relevant research regarding the administration of neuropsychological instruments via videoconferencing, and suggest methodological improvements for further studies. To date, only a handful of scientific studies have been published documenting the feasibility and acceptability of videoconferencing among older people and health professionals. Varying in their assessment tools, the studies demonstrate the reliability of cognitive testing and clinical diagnosis of dementia via videoconferencing, as noted by the associations between results of several cognitive tests using it as compared to face-to-face interviews. Further research is required to replicate findings and bring new solutions for their adaptation to a wide range of individuals, health professionals, areas of practice and settings.

Assessing Cognitive Function in Older Adults Using a Videoconference Approach

BACKGROUND

The use of communication technologies is an emerging trend in healthcare and research. Despite efficient, reliable and accurate neuropsychological batteries to evaluate cognitive performance in-person, more diverse and less expensive and time consuming solutions are needed. Here we conducted a pilot study to determine the applicability of a videoconference (VC, Skype®) approach to assess cognitive function in older adults, using The Telephone Interview for Cognitive Status-Modified - Portuguese version (TICSM-PT).

METHODS

After inclusion and exclusion criteria, 69 individuals (mean age=74.90±9.46years), selected from registries of local health centers and assisted-living facilities, were assessed on cognitive performance using videoconference, telephone and in-person approaches.

FINDINGS

The videoconference administration method yielded comparable results to the traditional application. Correlation analyses showed high associations between the testing modalities: TICSM-PT VC and TICSM-PT telephone (r=0.885), TICSM-PT VC and MMSE face-to-face (r=0.801). Using the previously validated threshold for cognitive impairment on the TICSM-PT telephone, TICSM-PT VC administration presented a sensitivity of 87.8% and a specificity of 84.6%.

INTERPRETATION

Findings indicate for the range of settings where videoconference approaches can be used, and for their applicability and acceptability, providing an alternative to current cognitive assessment methods. Continued validation studies and adaptation of neuropsychological instruments is warranted.
