There are many different varieties of depression-related research going on concurrently in the scientific world, which reflects just how complicated the disorder is. It's not like a broken leg, where the fix is obvious; depression involves a mixture of genetic, environmental and biological factors that combine to create an issue experienced, in its most severe form, by 15 million Americans. And that means both understanding and curing it is one of the trickiest problems on the table.
Luckily, though, new approaches keep giving us new opportunities to understand it, and the latest science out of Columbia University provides a fresh insight into an unexpected the idea: depression might be created by the way in which neurons "branch" in the brain.
As the difficulties many experience with antidepressants and the ongoing search for new therapies show, there isn't a 'magic bullet' for depression. Instead, there's still clearly a lot we've got to learn. While depression has been part of the human experience for millennia under various names, our approaches to curing it have run the gamut from the terrifying to the merely ineffectual; but with each new discovery, hopefully we're inching closer to something that might help the majority of sufferers.
