Clinical Trial Summary

This study attempts to replicate the findings published in Nature Medicine by Nation and colleagues (2019). By using a large observational cohort (DZNE - Longitudinal Cognitive Impairment and Dementia Study; DELCODE) consisting of cognitively healthy individuals, individuals with subjective cognitive decline, mild cognitive impairment, and dementia due to Alzheimer's disease, an association between the blood-brain barrier and cognitive dysfunction is investigated. The integrity of the blood-brain barrier is investigated by using a novel MRI protocol as well as a novel biomarker in the cerebrospinal fluid.

Eligibility

Inclusion criteria:

• = 50 years with neuropsychologically confirmed no cognitive dysfunction, mild cognitive impairment or mild dementia

Exclusion cirteria:

• no current or prior history of any neurological or psychiatric condition, which might affect cognitive function
• no neurodegenerative disease other than AD
• specifically no extensive vascular white matter dementia or vascular dementia

Related Conditions & MeSH terms

• Alzheimer Disease
• Blood Brain Barrier
• Cognitive Dysfunction
• Dementia

Intervention

Diagnostic Test:
• Contrast agent enhanced MRI using Gadovist
By using the contrast agent Gadovist we aim to visualize the blood-brain barrier. Furthermore, we aim to measure a newly developed biomarker of the blood-brain barrier in the cerebro-spinal fluid.
