Evaluation of a Plasma Marker (p-Tau217) for the Biological Diagnosis of Alzheimer's Disease, and Comparison With CSF Markers
This study checks whether a single blood test for a protein called p-Tau217 can match the results of a spinal tap (lumbar puncture) in diagnosing Alzheimer's biology. About 150 memory clinic patients in Amiens, France will give one extra tube of blood. It is a diagnostic study, not a drug trial, so no phase applies.
You may qualify if
- All patients addressed to the memory center of CHU Amiens with a clinical suspicion of AD, for whom lumbar puncture / CSF biomarkers of AD determination is proposed.
You're excluded if
- Minor patients
- pregnant women
- patients under guardianship
