≪Organizer Abstract≫
Dramatic increase in aging population of developed nations has spurred great interest in understanding lifespan changes in human brain and their impact on cognition. Recent advancement of neuroimaging made possible in vivo investigations of the structural and functional properties of the brain in conjunction with assessment of cognitive performance. In this symposium, we focus on changes in the brain and cognition in healthy and pathological aging and address four major questions. First, we examine how normal aging affects the brain structure. Second, we identify cognitive abilities that are differentially vulnerable to aging and survey the effects of aging on the underlying neural systems. Third, we evaluate the impact of remedial interventions on cognitive abilities of older adults. Finally, we discuss the continuity and differences between normal and pathological aging. As an overarching goal we seek to elucidate the implications of the surveyed empirical findings for theoretical foundations of cognitive aging.
