AB This study was aimed at exploring phaseamplitudecoupling (PAC) patterns of neural activity indementia due to Alzheimer’s disease (AD). For this task, fiveminutes of spontaneous electroencephalographic (EEG) activityfrom 22 patients with mild AD and 16 cognitively healthycontrols were studied. To assess PAC patterns, phase-lockingvalue was computed between the phase of low frequencies andthe power of high frequencies within each sensor. Our resultsshowed that high-frequency gamma power is phase-locked tothe alpha peak in EEG signals. Furthermore, statisticallysignificant differences (p<0.05, permutation test) betweenpatients with mild AD and elderly controls were observed atthe lower left temporo-parietal area, suggesting that earlystages of AD elicit a region-specific decrease of PAC in theneural activity.
