Multimodal brain testing for Alzheimer’s and mild cognitive impairment

Multimodal Assessment of Cognitive Impairment in Alzheimer Patients

Observational Norwegian University of Science and Technology · NCT06448403

This project will use MRI, EEG, sleep studies, and blood and stool tests to try to find brain and bodily changes that predict or distinguish Alzheimer’s disease and mild cognitive impairment.

What this trial studies

This observational project combines cognitive testing, structural and functional MRI, 64-channel EEG, randomized polysomnography in a subgroup, and blood and fecal sampling to map brain and systemic changes in people with late-onset Alzheimer’s disease, mild cognitive impairment, and matched healthy controls. Imaging will be analyzed for structural and functional alterations while EEG will measure changes in electrical activity, and polysomnography will characterize sleep-related features. Blood samples will be tested for dementia- and inflammation-related proteins and fecal samples will be analyzed for gut microbiome composition. Cognitive testing will link clinical performance to the biological and neurophysiological measures to identify markers that precede clinical decline or distinguish patient groups.

Who should consider this trial

Good fit: Adults aged 65 or older diagnosed with mild cognitive impairment or late-onset Alzheimer’s disease, and age- and sex-matched healthy controls who can undergo MRI and EEG, are ideal candidates.

Not a fit: People with early-onset AD (diagnosed before age 65), other neurodegenerative disorders, brain tumors, prior neurosurgery, major traumatic brain injury, inflammatory/autoimmune diseases, or who cannot undergo MRI/EEG are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this work could enable earlier and more accurate detection of Alzheimer’s-related decline and identify biological signals useful for tracking disease progression.

How similar studies have performed: Previous multimodal biomarker studies combining imaging, electrophysiology, and blood markers have shown promising leads but no single multimodal signature has yet become a definitive clinical diagnostic tool.
