[P300 and dementia: diagnostic relevance II].

Abstract

Recent research on the relationship between ERP-latencies and reduced information process capabilities with demented subjects has yielded divergent results. In the present study P300-latencies and RT are used in an attempt to differentiate between demented and nondemented subjects. Based on the "feature-integration-theory" of Treisman an experiment was designed in order to investigate more complex cognitive processes. The results showed that both P300-latency and RT may be used as additional diagnostic indices for cognitive capability.
