Neurogenesis, the process by which new neurons are generated from neural stem cells, is fundamental to brain function, plasticity, and recovery. For many years, it was believed that neurogenesis occurred only during early development, but research over the past few decades has shown that it persists into adulthood, particularly in the hippocampus and olfactory bulb. Adult neurogenesis plays a critical role in memory, learning, emotional regulation, and brain repair. Impairments in neurogenesis have been associated with cognitive decline, neurodegenerative diseases, brain injuries, and psychiatric disorders. Understanding the mechanisms regulating neurogenesis opens new avenues for therapeutic strategies aimed at treating conditions like Alzheimer’s disease, Parkinson’s disease, depression, and stroke. This article provides an overview of the process of neurogenesis, its roles in the adult brain, its decline with aging, and its potential for therapeutic interventions in neurological diseases.
