Neural stem cells exist in specialized regions of the brain and have the capacity to give rise to neurons and glia over the lifespan. The process of giving rise to new neurons, also known as neurogenesis, is thought to be important in cognition and certain types of brain repair. However, during aging, neural stem cell number and function is reduced resulting in fewer new neurons and declines in learning, memory and repair. Recently, research has approached this problem through the lens of rejuvenation that now has produced several strategies, from dietary to pharmacological interventions, to restore functional neurogenesis that resembles the youthful brain. Here, we outline aging in the subventricular zone neurogenic niche, review the multiple modalities of rejuvenation strategies, and propose next steps for future studies to approach translational outcomes.
