Cerebral correlates of alerting, orienting and reorienting of visuospatial attention: an event-related fMRI study.

abstract：:Alzheimer's disease (AD) is the leading cause of dementia, accounting for 70% of cases worldwide. By 2050, dementia prevalence will have tripled, with most new cases occurring in low- and middle-income countries. Mild cognitive impairment (MCI) is a stage between healthy aging and dementia, marked by cognitive deficit...
