A landmark study from Karolinska Institutet has confirmed that adults continue to generate new neurons in the hippocampus, the brain’s memory and learning hub. Remarkably, neurogenesis was observed across a wide age range, even in individuals up to 78 years old. This discovery challenges long-held beliefs that brain cell growth ceases in adulthood and instead highlights the brain’s lifelong plasticity. The finding has profound implications for developing treatments for memory decline, mood disorders, and neurodegenerative conditions such as Alzheimer’s. By proving that the brain can renew itself, researchers have unlocked new hope for therapies that could enhance cognition and resilience at any age.
