Could an overactive immune system cause depression?

Scientists in the UK are investigating whether some cases of depression could be triggered by an overactive immune system.

It's a theory which is rapidly gaining ground - and there are now a number of trials testing whether some anti-inflammatory drugs might help some patients with depression.

Anti-depressants don't work in a third of patients so if this new approach works it may offer them hope of an effective treatment.
