Longitudinal EEG findings in dementia related to the parietal brain syndrome and the degree of dementia.

EEG slow-wave activity was correlated with the regional brain syndrome profile in 74 patients with dementia. The EEGs were visually assessed using a semiquantitative rating scale. The intensities of four regional brain syndromes (parietal, frontal, subcortical, global) and the degree of dementia were rated. The patients were examined twice with a 1-year interval. A significant relationship was found between the increase in EEG slow-wave activity and the increase in intensity of the parietal brain syndrome. A somewhat lower significance was found for the relation between increase in slow-wave activity and increase in dementia degree. The results suggest that the EEG deterioration in dementia mainly reflects the gradual decline of parietal brain function.

EEG findings in dementia are related to the parietal lobe syndrome.

EEG indicators were correlated with clinical items in 174 patients with dementia diagnoses based on the DSM-III-R criteria. The patients' clinical symptomatologies were presented as regional brain syndromes, i.e. parietal lobe, frontal lobe, subcortical and global (nonregional) syndromes. The EEGs were abnormal in 87% of the cases. The typical abnormalities consisted of diffusely distributed slow wave activity. A significant correlation was found between the degree of slow wave abnormality and the degree of dementia. The results of the statistical analysis also suggest that EEG slow wave activity in dementia primarily reflects parietal lobe dysfunction. No association seems to exist between EEG slow wave activity and frontal lobe dysfunction.
