简要总结
Dementia with Lewy body disease (DLB) is the second leading cause of degenerative cognitive disorder after Alzheimer's disease (AD). Its variable clinical expression makes diagnosis difficult. To date, there is no validated DLB diagnostic biomarker, despite several biomarkers in development (EEG, MRI, biology).
Studies have shown that an improvement in diagnostic performance could be obtained by combining different modalities biomarkers using machine learning.
The aim of this research is to identify the best combination of multimodal biomarkers for the diagnosis of DLB (EEG, MRI, biology, cognitive scores), using a machine learning approach applied to a clinical cohort.
详细描述
Study population: Observational prospective cohort study including over 24 months at the GHU AP-HP. Nord Lariboisière, Cognitive Neurology Center : 50 probable DLB patients, 50 AD patients, and 30 control subjects with subjective cognitive impairment but without any element in favor of neurodegenerative disorders. Total clinical dataset n= 130.
Act :
- 32-electrode EEG (resting state, passive auditory and active visual task).
- 4 dry electrode EEG cap simultaneously with the 32-electrode EEG
Expected results: Improved DLB diagnosis performance using a combination of multimodal biomarkers (EEG, cognitive scores, plasma, brain MRI).

结局指标
主要结局
Diagnostic performance of a composite multimodal score
时间窗: 24 month
Diagnostic performance (sensitivity, specificity, accuracy) of a composite multimodal score combining quantitative EEG metrics, plasma biomarkers, MRI volumetric markers and cognitive scores, to differentiate groups of patients (AD, DLB) and control subjects.
次要结局
- Comparison between groups of patients and controls of a composite EEG score combining several quantitative EEG parameters.(24 month)
- Correlation between EEG parameters, biological biomarkers, MRI volumetric markers and cognitive scores assessed in the three groups (DLB, AD, controls)(24 month)
- Reproducibility of 32-electrode EEG results with the 4 dry electrodes EEG cap(24 month)
