Why Depression Isn’t What You Think | Lisa Monteggia | TED

The idea that depression comes from a chemical imbalance in the brain has shaped treatment for decades. Neuroscientist Lisa Monteggia shares research suggesting that's not the whole story — and shows how a decades-old drug could upend what we thought we knew about depression, with the potential to offer relief within hours. (Recorded at TEDxNashvilleWomen on August 21, 2025)
