Background: The conventional electroencephalography(EEG) is commonly used as aid in the diagnosis of dementia. Recently developed quantitative electroencephalography (qEEG) provides data that are not achievable by conventional EEG. The aim of this study was to find out the usefulness of quantified-EEG in dementia.
Method: Twenty elderly women(10 normal elderly, 10 demented elderly) were participated in this study. EEG power and coherence was computed over 21 channels; right and left frontal, central, parietal, temporal and occipital areas.
Result: The activity of αwave was more higher than others significantly at frontal and parietal areas in normal elderly, but the activity of θwave was higher in demented elderly. And the activity of θwave in demented elderly women was more higher than normal elderly women significantly.
Conclusion: In conclusion, we discovered that quantitative EEG was used to diagnose dementia.
