Abnormalities of resting-state functional cortical connectivity in patients with dementia due to Alzheimer's and Lewy body diseases: an EEG study
Previous evidence showed abnormal posterior sources of resting-state delta (
rhythms in patients with Alzheimer’s disease with dementia (ADD), Parkinson’s disease with dementia
(PDD), and Lewy body dementia (DLB), as cortical neural synchronization markers in quiet wakefulness.
Here, we tested the hypothesis of additional abnormalities in functional cortical connectivity computed
in those sources, in ADD, considered as a “disconnection cortical syndrome”, in comparison with PDD
