Examining how the brain clears amyloid-β in Alzheimer's disease
Official title: Amyloid-β Clearance Mechanisms: A Multi-modal Study on Lymphatic, Glymphatic and Blood-brain-barrier Function in Alzheimer's Disease
Run by Ludwig-Maximilians - University of Munich · NCT05059158 · Data updated 2026-11-12
This study is trying to understand how the brain gets rid of a harmful protein in people with early signs of Alzheimer's disease to help find better treatments in the future.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals diagnosed with amnestic mild cognitive impairment or mild Alzheimer's disease who can provide informed consent.
✕Probably not a fit
Patients with severe mental disorders, significant neurological conditions, or those unable to provide informed consent may not benefit from this study.

What this trial studies
This observational study investigates the mechanisms behind the accumulation and clearance of amyloid-β (Aβ) deposits in the brain, particularly focusing on the role of the blood-brain barrier and the glymphatic system. Participants with subjective cognitive decline, mild cognitive impairment, and mild Alzheimer's disease will undergo detailed clinical assessments, including MRI and PET imaging, to better understand the interactions affecting Aβ removal. The study aims to develop a mechanistic model of Aβ clearance that could inform future therapeutic strategies. Follow-up assessments are planned for a subsequent study pending funding.
Why it matters
Potential benefit: If successful, this study could enhance our understanding of Alzheimer's disease pathology and lead to improved treatment strategies for patients.
How similar studies have gone: While the mechanisms of amyloid-β clearance are being actively researched, this specific approach integrating glymphatic pathways is relatively novel.
