Depression linked to stalled brain cell formation in adults, study finds

Deep within the human brain, in a region that holds the architecture of memory and learning, depression appears to do something more precise than previously understood — not eroding tissue wholesale, but quietly halting the birth of new cells. Researchers have identified dysregulated neurogenesis in the hippocampus as a primary mechanism of depression's cognitive toll, a finding that reframes decades of assumption and opens a more targeted path toward healing. Where the old story spoke of shrinkage and loss, this new chapter speaks of interruption — and interruption, unlike erosion, may be som
