Electroencephalography as an Aid in the Exclusion of Alzheimer's Disease

The value of quantitative EEG in differential diagnosis of Alzheimer's disease and subcortical vascular dementia

“…In our study we have registered pathological EEG changes such as reduced background activity and an increase in the amount of theta and delta waves in 82% of our patients. These results are similar to those reported in other studies, such as for example, more systematic investigations of Robinson [27], which found EEG abnormalities in 87.7% of patients with Alzheimer's disease. Some authors describe EEG abnormalities mainly as a presence of theta waves [27,28].…”

Associations between Patterns of EEG Abnormalities and Diagnosis in a Large Memory Clinic Cohort

“…The more frequent demonstration of both focal and diffuse EEG abnormalities in DLB and VaD compared to AD is in agreement with previous studies [12,14,18,19] , although 1 study found focal abnormalities not sufficiently prevalent to distinguish VaD from AD [13] . Two studies failed to distinguish DLB from AD by visually scoring predominantly diffuse EEG disturbances on a 4-point scale [15,16] , which is probably less sensitive than the visual interpretation of an EEG pattern, which includes the scoring of both diffuse and focal abnormalities.…”

The Prevalence of Dementia in Down Syndrome

“…The EEG results are in accordance with previous find ings both in the general population [37] and in Down syn drome [1][2][3]38]. These data show that EEG abnormali ties only can be used as additional, not as conclusive sup port to diagnosis of dementia.…”
