It’s estimated that 1 in 8 to 1 in 5 people have depression, but it’s mostly those at the moderate to the severe end who turn to antidepressants. This week, we wanted to delve into how exactly antidepressants work and the scientific impact they have on the alchemy of the brain. Joining Jonathan to discuss this is Dr. Christelle Langley, Cognitive Neuroscientist at the Department of Psychiatry at the University of Cambridge. Dr. Oran Kennedy from the Dept of Anatomy & Regenerative Medicine and the Tissue Engineering Research Group at RCSI & Dr. Susan Kelleher from DCU also joins Jonathan for Newsround.
