Brain network modulation in Alzheimer’s disease:clinical phenotypes and windows of opportunity

摘要

Dementia,for which there is no cure or effective treatment,is the leading cause of disability and death worldwide.Due to the high global prevalence and economic impact on families,caregivers,and communities,this condition represents one of the most significant public health challenges of our time.Dementia is an umbrella term describing a range of progressive neurodegenerative diseases,including Alzheimer’s disease(AD),which is the most common cause of cognitive and functional impairment among older adults.The presence of misfolded protein aggregates characterizes neurodegenerative disorders(e.g.,amyloid-beta(Aβ)and tau in AD).
