Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study the investigators explore a pragmatic strategy to increase cognitive screening rates in the community. The investigators will compare the monetary value of different combinations of SCD questionnaires, digital cognitive tests, and blood Alzheimer's Disease (AD) biomarkers to identify the best approach for primary care settings.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators aim to perform a cluster-randomized study, exploring the effectiveness, efficiency, and acceptability of a pragmatic strategy to increase cognitive screening rates in the community. Participants will be older adults attending social and cultural centers in the greater Munich area. The investigators will compare the monetary value of different combinations of SCD questionnaires, digital cognitive tests, and blood AD biomarkers to identify the best approach for primary care settings. As secondary aims, qualitative interviews will be conducted with general practitioners (GPs) and their patients to explore the acceptability of the proposed new screening strategy; furthermore, the diagnostic utility of an artificial intelligence-based automated analysis of speech will be assessed. The initiative will not only generate novel insights into the optimal approach for large-scale cognitive screening in the general population, but also contribute to an urgently required cultural change in Germany, resulting in a sustainable solution for effective and efficient early recognition and prevention of dementia.

Study Groups

Subjective Cognitive Decline Questionnaire (SCD-Q)/no other procedure

Participants will undergo procedure as usual and fill out the questionnaire SCD-Q

Group Type OTHER

Subjective cognitive decline questionnaire (SCD-Q)

Intervention Type DIAGNOSTIC_TEST

The SCD-Q is a validated questionnaire assessing the presence of subjective cognitive deterioration in abilities such as memory, attention, language, and executive function. The scale includes 24 dichotomous questions (yes/no), evaluating decline in daily life during the last two years. The SCD-Q score ranges from 0 to 24, with higher scores indicating greater perceived cognitive change (cut-off classified as SCD equal or greater as 7).

ki:elements digital speech biomarker for cognition (ki:e SB-C)

Intervention Type DIAGNOSTIC_TEST

The ki:elements digital speech biomarker for cognition (ki:e SB-C) can be collected remotely in fully automated telephone visits, taking 15 minutes to complete based on three specific assessments measuring learning and memory, processing speed, executive function, and language capabilities. The ki:e SB-C uses artificial intelligence and automatic speech analysis to process and transcribe speech, followed by an extraction of relevant features, combined into four subdomain and one global cognition score.

SCD-Q + digital cognitive testing using Cognigram

Participants will undergo procedure as usual with their GP, additionally they will fill out the SCD-Q and undergo cognitive testing (Cognigram)

Group Type OTHER

Cognigram

Intervention Type DIAGNOSTIC_TEST

Cognigram (previously known as the Cogstate Brief Battery) is a brief, computer-administered cognitive test battery requiring about 20-25 minutes for administration, consisting of four cognitive tasks to measure psychomotor function, attention, working memory, and learning and memory. Eisai owns the commercial rights for Cognigram and has kindly agreed to offer the required licenses for the present project free of charge. Digital cognitive testing will take place in the respective social and care centers on a tablet which is not connected to the internet. Testing will be performed pseudonymized and data from the cognitive tests will be downloaded regularly by the study team and added to the database at LMU hospital.

Participants will undergo procedure as usual with their GP, additionally they will fill out the SCD-Q and undergo cognitive testing (Cognigram). The blood-based biomarkers will be determined.

blood-based biomarkers

Intervention Type DIAGNOSTIC_TEST

Blood plasma and serum samples will be collected by the project staff according to standard operating procedures used at LMU Munich and subsequently processed and measured at the Department of Psychiatry and Psychotherapy to quantify the blood-based biomarkers for AD using Elecsys immunoassays running on a Cobas e402 analyzer. All test results (including the respective cut-off measurements for normal vs abnormal) will be forwarded directly to the participants' GPs. No further explanations and instructions will be provided to avoid any unwanted bias, and participants will only be informed about their results by their doctors. Roche has kindly offered to provide blood biomarker assays free of charge for the present project.
