Most antidepressants work by altering serotonin or dopamine levels, and they can take weeks to show effect. Ketamine takes a different path. At low doses, it targets the brain’s NMDA receptors and boosts glutamate, a neurotransmitter tied to learning and memory. That surge triggers a wave of new neural connections, essentially giving the brain a chance to “rewire” itself if depression or trauma has disrupted communication.
The experience isn’t about masking symptoms. It’s about creating conditions where mood, motivation, and clarity can return. For many patients who’ve struggled with long waits or limited results, ketamine therapy in Greenwich offers a faster, more science-driven way to move forward.
