Do you ever wonder what makes us tick? The way we act, feel and even process information from the world around us? All of it starts with the brain. CNN's Chief Medical Correspondent Dr. Sanjay Gupta is tapping his decades of experience as a neurosurgeon to explore the many states of the brain – distracted, nourished, concussed, frightened and more. Our brains are in constant conversation with our bodies, so the condition of one can have direct effect on the other. Sanjay will provide insights into how to actually build a stronger brain and keep it sharp.
Nearly one in five US adults are diagnosed with depression at some point in their lives. As the use of antidepressants have steadily risen since their introduction in the 1980s, what have we learned about depression? Is depression truly a “chemical imbalance” of the brain? And why do antidepressants work for some people and not others? Sanjay talks to Dr. Charles Raison, a professor of psychiatry at the University of Wisconsin-Madison, about what we now believe causes depression, and most importantly, what this means for how we treat the illness - from SSRIs to psychedelics and other emerging therapies.
