Abstract
Visual evoked potentials (VEPs) to pattern-reversal and motion stimulation as well as visual cognitive potentials (ERPs) were tested in 15 patients with mild to moderate Alzheimer disease and in 15 age, gender and education level matched healthy controls. We found significantly reduced amplitudes of motion related VEPs, which objectively confirms a dysfunction of motion processing in Alzheimers disease.
The ERPs displayed significantly delayed latencies, which can be used especially in intraindividual assessment of disease progress and effect of therapy.
