About this study

Official title: Study of the Predictive Markers and the Pathophysiological Mechanisms of Alzheimer's Disease: Transverse and Longitudinal Approach in Anatomical and Functional Multimodal Imaging

According to estimations, Alzheimer's disease affects approximately 860,000 people aged of more than 65 years in France. This disease is characterized by disorders of cognitive functions, including memory, associated with structural and functional modifications of the brain. These changes are evolving within the pathology progression and can be evaluated with neuropsychological tests (to assess capabilities such as language, orientation, etc.) and also with brain imaging (e.g. MRI). Alzheimer's disease is still poorly understood, nevertheless currently available treatments can slow its development if the disease is diagnosed early enough.

Thus, the objective is to identify markers for early diagnosis of Alzheimer's disease, to better describe the evolution of this disease.

The three main objectives of this project are

  • to identify, compare and combine predictive markers of Alzheimer's disease
  • to make a significant contribution to the understanding of the pathophysiological mechanisms of Alzheimer's disease
  • to study the ability of different neuroimaging techniques to follow the evolution of this pathology.
Being tested
assessment of memory, circulating tPA dosage, ApoE4, Brain imaging examination MRI and PET examinations

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of volume change of whole brain, hippocampus and other structural MRI measures (time frame: 3 years). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01554202, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2013.
