What this trial studies

This study aims to validate the Subjective Cognitive Decline Questionnaire (SCD-Q) in the German language for patients undergoing dementia diagnostics. The SCD-Q is a screening tool that assesses self-perceived cognitive decline and includes both self-reported and informant-rated versions. The study will also explore the relationship between the SCD-Q results and various biomarkers associated with Alzheimer's disease, as well as cognitive tests. Follow-up visits will be conducted to gather comprehensive data on cognitive changes over time.

Who should consider this trial

Good fit: Ideal candidates are individuals attending medical appointments for dementia diagnostics who can provide informed consent.

Not a fit: Patients with advanced-stage dementia or those who are illiterate may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a validated tool for early detection of cognitive decline in German-speaking populations.

How similar studies have performed: Other studies have successfully validated similar cognitive assessment tools, but this specific validation in German is novel.
