Stanford's Robert Sapolsky: 'Depression is like the worst disease you can get'

We've all felt a little blue, down in the dumps, or just plain sad. But when a serious depression sets in, it could be weeks, months or even years before the feeling lifts.

During a recent workshop presented by Stanford's Faculty and Staff Help Center, biologist Robert Sapolsky talked about the biological and psychological causes of depression, how to recognize its symptoms and how to handle the disease.

Depression is the world's fourth leading cause of disability and is on track to be second only to obesity-related disorders by 2025, Sapolsky said.

"Depression is incredibly pervasive and thus important to talk about," he said. "Depression is like the worst disease you can get. It's devastating."
