摘要：

We studied the occiptal inter-hemispheric coherence (IHCoh) of EEG (electrodes O1-O2) for alpha band (alpha(1) - 8,0 to 10,0 Hz and alpha(2) - 10,1 to 12,5 Hz) in healthy adults and Alzheimer's type dementia (ATD) subjects, to observe if there is any significant difference between these two groups that could help in the early diagnosis of ATD. We found a decrease of occipital IHCoh in ATD group for both alpha sub-bands. We believe that Coh analysis of EEG is a powerful auxiliary method in ATD diagnosis.
