Abstract Share this page

Abstract New neurons are continuously generated and added to neural circuits in the adult brain. However, increasing age imposes changes in neural progenitor cells and their microenvironment that lead to a reduction of neurogenesis. Age-related decreased production of new neurons in the neurogenic dentate gyrus has been associated with memory impairments. Several mechanisms are known that might counteract this decline in cognitive functions. Here, we give an overview of ageing-related changes in neurogenesis in the brain of humans and rodents. We discuss possible causes for reduced neurogenesis with age, its consequences on cognition, and how neurogenesis might be restored in old age. © 2014 S. Karger AG, Basel.
