Brain Connectivity Marker for Alzheimer's Disease

Clinical Application of a Brain Connectivity Marker for Early Detection of Alzheimer's Disease


Sponsor

Karolinska Institutet

Enrollment

120 participants

Start Date

Apr 1, 2023

Study Type

OBSERVATIONAL

Conditions

Summary

The main purpose of this project is to establish whether changes in brain connectivity can be used to predict the development of Alzheimer's disease (AD).


Eligibility

Min Age: 40 YearsMax Age: 85 Years

Inclusion Criteria15

  • MMSE (Mini-mental test) or MoCA (Montreal Cognitive Assessment) points between 26 and 30.
