Modeling Transient Oscillations in the EEG of Patients with Mild Cognitive Impairment
We explore the potential of transient local synchrony in EEG, as a marker for MCI (mild cognitive impairment). EEG signals of patients with MCI are transformed to a wavelet time-frequency representation, and afterwards a sparsification process (bump modeling) extracts time-frequency oscillatory bursts. We observed that organized oscillatory events contain stronger discriminative signatures than averaged spectral EEG statistics for patients in a probable early stage of Alzheimers disease. Specifically, bump modeling enhanced the difference between MCI patients and age-matched control subjects in the 0 and high fi frequency ranges. This effect is consistent with previous results obtained on other databases.
