Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Mild Alzheimer

Patients above 65 diagnosed with Alzheimer's Disease according to appropriate ICD-criterias.

7T MRI

Intervention Type DEVICE

Resting-state EEG

Blood samples

Intervention Type BIOLOGICAL

Blood samples taken for analysis of central blood biomarkers.

Stool samples

Intervention Type BIOLOGICAL

Stool samples collected to identify distinct gut-microbiota compositions between the groups.

Neuropsychologic test (MoCA)

Intervention Type DIAGNOSTIC_TEST

Map cognition with clinically well-established neuropsychology test

Controls
