title: Visual evoked potentials in elderly patients with primary or multi-infarct dementia.
abstract: Flash and pattern-reversal visual evoked potentials (VEP) were recorded in 35 elderly patients with dementia, and 19 controls of equivalent age. Dementia produced a slowing of the major positive (P2) component of the flash VEP but did not affect the latency of the flash P1 component or the P100 pattern-reversal component. This unusual type of abnormality was found in both primary and multi-infarct types of dementia, and has previously been found in primary presenile dementia. The results show that the VEP can be used for the diagnosis of multi-infarct, and primary presenile and senile dementias.
