Question

Do blind people suffer from depression because of light deprivation?

Answer

We put this question to Professor Russell Foster:

I think it's such an interesting idea because we've published a paper last year on an individual who has no rods and cones but can still regulate their body clock using these new receptors to the light-dark cycle. It's only with the discovery of these cells that we can ask question like that. The assumption then, has been - well, you're depressed because you can't see. We're starting some studies to look at depression in individuals who have those cells but don't have the capacity to see.
