Brain-zapping headset could help treat depression

A new headset could give people with depression more control over their treatment.

The device uses weak electrical activity to stimulate parts of the brain and it comes with an app that guides people through virtual therapy sessions.

But how effective is it likely to be?

Philip King, who is visually impaired has lived with depression for 19 years and attends dance and movement sessions at Birmingham Centre for Arts Therapies.

He welcomes anything new that could move treatment away from pills - but some psychologists are sceptical about how useful the new device will be.
