[P300 in mild cognitive impairment and in dementia].

Abstract

The prolongation of P300 latency was significant among patients with both vascular and Alzheimer's dementia, and also among MCI patients with mild cerebral atrophy. The severity of dementia is positively correlated with P300 latency; however, this prolongation is independent of the type of dementia. The structural brain changes in MCI are related to P300 latency prolongation and thus may indicate an increased risk for developing dementia in MCI patients.
