The P300 component of the auditory EEG event-related potential (ERP) and Positron Emission Tomography (PET) were investigated in individuals considered to be early cases of probable Alzheimer's type dementia (PAD) and a control group of similar age. Two questions were investigated: (a) The degree to which P300 latency was sensitive to neurocognitive changes in very early stages of PAD; and (b) The relationship between P300 latency and specific areas of reduced neural functions as reflected in PET scans. A significant difference was found between PAD and normal subjects in P300 latencies, with those in the patient group having longer P300 …
