“…Our findings are in accordance with other studies showing spectral ''slowing'' in AD (Czigler et al 2008;Dauwels et al 2010aDauwels et al , b, 2011van der Hiele et al 2007). For instance, Jeong (2004) have observed a slowing of the resting EEG in AD patients, reflected by a higher power in the theta frequency band.…”

“…In addition, the relative PSD values were increased in the theta frequency band and significantly decreased in the alpha2 frequency band for AD patients. From the view of global cognition, decreased alpha2 reactivity is associated with the worse performance on memory (Jelic et al 2000;van der Hiele et al 2007). Thus, only the alpha2 frequency band where the group difference was significant was chosen to further assess the abnormalities of AD brain in this work.…”

“…In addition, at present, the precise relation between the decline of cognition and memory and EEG abnormalities in AD patients remains largely unexplored (but see [64,18,17,57]). It is also of great importance to investigate whether EEG helps to distinguish between MCI and different stages of AD (see, e.g., [16]), and between AD and other dementias (see, e.g., [25][26][27][28][29][30]).…”

“…Many studies have shown that Alzheimer's disease (AD) causes EEG signals to slow down (see, e.g., [5,10,[18][19][20][21][22][23][24]28]): AD is associated with an increase of power in low frequencies (delta and theta band, 0.5-8Hz) and a decrease of power in higher frequencies (alpha and beta, 8-30Hz, and gamma, 30-100Hz). To quantify the changes in spectral power, one has applied Fourier transforms [5,10,[18][19][20][21][22]28] and sparsified time-frequency maps ("bump models") [23,24].…”
