| Popis: | Normal aged subjects (65–83 years) were examined by EEG and CT brain scan; also a Geriatric Mental Scale (GMS) and Neuropsychologic Assessment Battery were administered. Based on the EEG findings 2 subgroups could be distinguished: one with focal abnormalities in the left fronto-temporal region and one without these focal abnormalities. The focal delta subgroup proved to perform poorly on the Fluency Test, a simple quick bedside, but very sensitive, test for word association productivity. Also this subgroup showed more ventricular dilatation than the non-focal group. Therefore slight left-sided antero-temporal abnormalities in normal aged subjects are not irrelevant but an early (subclinical) sign of temporal lobe pathology as expressed in deterioration of language function. |
