New support for a serotonin deficit in depression

Since the 1960s, researchers have postulated that major depression stems from disruptions in the serotonin neurotransmitter system, but the evidence for that idea, though plentiful, was indirect. In fact, a recent comprehensive analysis of existing studies concluded that there was not strong evidence to support the 'serotonin hypothesis.' In its wake, some in the field have called for a reexamination of the hypothesis. Not so fast, says a new study that provides direct evidence of disrupted serotonin release in the brains of individuals with depression.
