A rethink is needed in terms of how we view mental illness, stated National Institute of Mental Health Director Thomas Insel, M.D., in a recent TEDx talk at the California Institute of Technology (Caltech) in Pasadena.

Insel believes part of the problem is that mental illness is referred to either as a mental or behavioral disorder. “We need to think of these as brain disorders,” he said, adding that for these brain disorders, behavior is the last thing to change.
