Researchers report that lithium, a drug commonly used for the treatment of mood disorders in humans, restores neurogenesis in the hippocampus, a part of the brain strongly associated with learning and memory. Down syndrome is a neurodevelopmental disorder that is the leading cause of genetically defined intellectual disability. In the brain, Down syndrome results in alterations in the connections between neurons and a reduction in the development of new neurons (neurogenesis) that usually occurs during learning.
