Neurophysiological Correlates of Cognitive Tasks in Healthy Volunteers -WP3 P003 (PharmacogWP3)
Neurophysiological Correlates of Cognitive Tasks in Healthy Volunteers -A Pilot Study WP3 P003
In the perspective to better evaluate the efficacy of new treatment strategies for Alzheimer disease (AD), it appears important to develop experimental paradigms to precisely measure cognitive endpoints/biomarkers that may be used in healthy volunteers as tools to validate drug efficacy profile.
The use of Electroencephalography (EEG) may be, therefore, a good candidate. The purpose of the present study is to use EEG to more precisely explore cognitive processes in healthy subjects, with a particular interest in episodic and working memory functions that are usually altered in both AD and Mild Cognitive Impairment (MCI) as well as to better understand underlying neural mechanisms involved in these processes.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
EEG spectral power during RVIP task as compared to resting state
Time Frame: within 7 days after inclusion ( session1)
|
The Rapid Visual Information Processing (RVIP®) is a test of sustained attention and has proved useful in many studies in which drugs are used to help develop a disease model.
It is sensitive to dysfunction in the parietal and frontal lobe areas of the brain
|
within 7 days after inclusion ( session1)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
EEG spectral power during PRM task as compared to resting state
Time Frame: within 7 days after inclusion ( session1)
|
the Pattern Recognition Memory (PRM®) is a test assessing visual recognition memory, considered as a sensitive measure of medial temporal areas dysfunction.
It is a useful tool for assessing patients with MCI and AD
|
within 7 days after inclusion ( session1)
|
RVIP latency of responses
Time Frame: within 7 days after inclusion ( session1) and within 7days after session 1 (=session2)
|
within 7 days after inclusion ( session1) and within 7days after session 1 (=session2)
|
|
PRM number of errors
Time Frame: within 7 days after inclusion ( session1) and within 7 days after session 1 (=session2)
|
within 7 days after inclusion ( session1) and within 7 days after session 1 (=session2)
|
|
PRM latency of responses
Time Frame: within 7 days after inclusion (=session1) and within 7 days after session 1 (=session2)
|
within 7 days after inclusion (=session1) and within 7 days after session 1 (=session2)
|
|
difference between session 2 and session 1 EEG Spectral power during RVIP task
Time Frame: at 7 days after session 1
