Abstract:Alzheimer′s disease (AD) is a typical brain cognitive dysfunction, having serious impacts on the patient′s work and life. Early diagnosis of this disease has been one important issue that attracts intense attention and also a meaningful work. EEG contains a lot of functional information in favor of early diagnosis of brain cognitive dysfunction. Our study based on the pathogenesis of AD summed up the conventional diagnostic methods of AD, and further reviewed the current situation of the EEG analysis method, such as the EEG power spectrum, evoked potentials, approximate entropy and complexity, etc. The perspective in this field was discussed as well.
