Background.
Event-related oscillations (ERO) may provide a useful tool for the identification of cognitive deficits in mild cognitive impairment (MCI) and Alzheimer's disease (AD).
In the present study, we investigate peak-to-peak amplitude of auditory event-related delta oscillations of MCI subjects.
Method.
The study included twenty-two consecutive patients with MCI recruited in neurology clinic and 21 age- and education-matched normal elderly controls.
A classical auditory oddball paradigm was used in the experiments.
EEG was recorded from F3, Fz, F4, C3, Cz, C4, P3, Pz, P4, O1, Oz, and O2 locations.
The maximum peak-to-peak amplitudes for each subject’s averaged delta response (0.5–2.2 Hz) were measured.
Results.
The amplitudes between groups differed significantly at the frontal and mid-centroparietal locations.
ANOVA on delta responses revealed a significant effect for groups (F(1.41) = 4.84, P=0.033), indicating a larger delta response for healthy controls than MCI subjects.
Post hoc comparisons revealed that peak-to-peak delta response was significantly larger for healthy controls than for MCI over electrode sites F3, Fz, F4, Cz, C4, and Pz.
Discussion.
Event-related delta frequency band seems to be the most affected oscillatory response in cognitive impairment due to AD.
Therefore, it deserves to be investigated as a candidate electrophysiological biomarker in further studies.
