Visual mismatch negativity highlights abnormal pre-attentive visual processing in mild cognitive impairment and Alzheimer's disease.

Abstract:

Alzheimer's disease (AD) and mild cognitive impairment (MCI) are traditionally characterised in relation to abnormalities in higher-level brain function, particularly memory. However, in the study presented here we report significant abnormality in pre-attentive visual processing in both MCI and AD compared to healthy ageing. The functional integrity of the automatic change detection system was determined by measuring the visual mismatch negativity (vMMN) component of the N2 visual event-rela...
