Key Points

This review aims to explore how different cognitive tasks affect the P300 event-related potential in Alzheimer's disease and mild cognitive impairment.
Audiovisual oddball tasks were analyzed for P300 latency and amplitude changes in Alzheimer's and MCI.
Working memory and executive function tasks were reviewed for their impact on P300 responses.
Standardized EEG methods were emphasized for the clinical application of P300 findings.
Alzheimer's disease showed significant P300 latency delays during auditory oddball tasks.
Reduced P300 amplitude was most consistent in mild cognitive impairment during working memory and executive tasks.
Task type significantly influenced P300 group effects, highlighting the importance of standardized methods.

Implication

Scoping review reveals how cognitive tasks influence P300 measurements in Alzheimer's and mild cognitive impairment, indicating clinical potential.

Abstract

• Auditory oddball tasks best revealed P300 latency delays in Alzheimer's disease. • Working memory and executive tasks most consistently reduced amplitude in MCI. • Visual and executive tasks revealed latency differences in selected MCI samples. • Task demands critically shaped whether P300 component showed group effects. • Standardized tasks and EEG methods are essential for clinical P300 translation.
