On the first episode of NPR TED Radio Hour on Newstalk FM: 

The Unquiet Mind: 

We’ve all had that moment. The moment where you might see or hear something and you wonder: am I going crazy? In this hour, TED speakers share their experiences straddling that line between madness and sanity -- and question if we’re all in the grey area between the two.

On the first edition of TED Radio Hour on Newstalk FM, Neurologist Oliver Sacks explains Charles Bonnet syndrome - when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in detail and walks us through the biology of this under-reported phenomenon.

Elyn Saks says she's not schizophrenic, she's a person with schizophrenia. Saks was able to rise above her grave diagnosis to become a respected legal scholar. She asks us to see people with mental illness clearly, honestly and compassionately.

Comedian Joshua Walters, who's bipolar, walks the line between mental illness and mental "skillness." He asks: What's the right balance between medicating craziness away and riding the manic edge of creativity and drive?

Is there a definitive line that divides crazy from sane? With a hair-raising delivery, Jon Ronson, author of The Psychopath Test, illuminates the grey areas between the two. 

NPR TED Radio Hour on Newstalk 106-108 FM, Sunday's from 6pm.
