Is this trial a fit for you?

Likely a good fit

Adults in Germany who can provide informed consent (or have a legal representative), have a diagnosis of subjective cognitive decline, mild cognitive impairment, or early dementia, and have or are willing to undergo biomarker testing are ideal candidates.

Probably not a fit

People with advanced or late-stage dementia, those without available biomarker data, or those who cannot consent or attend participating German centers are unlikely to receive direct benefit from this registry.

What this trial studies

The German Dementia Registry is a prospective, multicenter platform that collects longitudinal real-world clinical data and biomarker results from patients with SCD, MCI, and early dementia across participating German sites. Data are entered via an online platform and aligned with diagnostic and treatment guidelines to capture routine clinical practice. The registry will track disease progression, biomarker dynamics (for example CSF amyloid and tau measures), and treatment patterns to help distinguish Alzheimer's disease from other dementia causes. Collected information is intended to support improved early diagnostic criteria and inform use of newly approved treatments in real-world settings.

Why it matters

Potential benefit: If successful, the registry could improve understanding of dementia progression and help refine biomarker-based early diagnosis and treatment decisions.

How similar studies have gone: Other large cohorts and registries (for example ADNI and several European national registries) have successfully provided natural-history and biomarker data, so this approach builds on established methods rather than being entirely novel.
