Correlation between mini-mental state examination and quantitative electroencephalography in senile dementia of Alzheimer type.

The quantified electroencephalogram (qEEG) of patients with senile dementia of the Alzheimer type (SDAT) and normal elderly subjects was related to the Mini-Mental State (MMS) score. A statistically significant correlation was observed between MMS score and some qEEG parameters. This correlation indicates that the use of adequate spectral parameters of qEEG may provide information on the cognitive impairment of elderly subjects and may reduce the false-positive rate at a neuropsychological examination.
