Sensitivity of Brief Sustained Attention Measures as Markers for Very Mild Alzheimer's Disease

Individuals in the very earliest stages of AD appear to show performance deficits in the arousal-based sustained attention. However, in terms of mind wandering, individuals in the very earliest stages of AD had more mind wandering during the executive-based SART. Collectively, sustained attention deficits in very early AD arise in both arousal and executive components but might manifest differently depending on how sustained attention ability is measured.
