Is association of EEG , MRI , and regional blood flow biomarkers predictive of prodromal Alzheimer 's disease?
High EEG upper/low alpha power ratio was connected with cortical diminishing and lower perfusion in the temporoparietal brain area. The increase in EEG upper/low alpha frequency power ratio could be helpful in recognizing people in danger of conversion to AD dementia and this may be quality information in connection with clinical assessment.
MRI measurements of ventricles are significantly larger than the measurements by US by ∼1 mm. There is a good level of agreement when categorizing by normal, mild and severe ventriculomegaly.
