Relapse of depression after rapid depletion of tryptophan.
BACKGROUND: Major depression is a common disorder but the pathophysiology is poorly understood. Current hypotheses implicate deficient function of brain serotonin pathways because drugs that selectively increase brain serotonin activity are effective antidepressants. However, there is no direct evidence that lowered serotonin function causes major depression. We aimed to assess whether lowering of brain serotonin activity by depletion of its amino acid precursor, tryptophan, could provoke a s...Expand abstract
