“…Furthermore, other studies using EEG power have found promising results (Claus et al, 1999, Lehmann et al, 2007, Snaedal et al, 2012 but had low sample size (Claus et al, 1999) or were not able to replicate the findings (Ommundsen et al, 2011). However, more advanced EEG techniques, such as feature (Trambaiolli et al, 2017), entropy (Abasolo et al, 2005), and amplitude modulation (Fraga et al, 2013), have shown promising results but with low sample sizes. In addition, the accuracies above 95% are higher than conventional Alzheimer's disease biomarkers, including fludeoxyglucose PET, cerebrospinal fluid biomarkers, or MRI, which has been shown to be >80% (Frisoni et al, 2013).…”
