Tryptophan depletion and risk of depression relapse: a prospective study of tryptophan depletion as a potential predictor of depressive episodes.
BACKGROUND This study investigated the relationship between depressive symptom response during tryptophan depletion and future depressive episodes. METHODS Twelve subjects with prior major depressive episodes in remission and medication-free for > or =3 months (patients), and 12 matched healthy (control) subjects received two tryptophan depletion tests 1 week apart. During follow-up the Hamil...
متن کاملBrain mechanisms associated with depressive relapse and associated cognitive impairment following acute tryptophan depletion.
BACKGROUND Acute tryptophan depletion lowers brain serotonin synthesis and results in a transient, but striking, clinical relapse in recovered depressed patients. AIMS To identify brain regions which change their activity as an acute depressive relapse evolves and to determine how pathological mood might modulate neural activity during a cognitive task. METHOD We used H2(15)O positron-emiss...
