NEUROTRANSMITERS
biologival explanation.believed group of neurotransmitters (e.g.seretonin) have lower levels in the brain of depressed individuals
3 of 10
NEUROTRANSMITTERS SUPPORT
MCNEIL & CIMBOLIC cerebrospinal fluid in depressed had less seretonin=reduction seretonin in brain.DELGADO ET AL diet lowered Trp. P's returned symptoms.RUHE ET AL remission Trp defcient diet had relapse.ROSEN ET AL urine,high enzymes act on seretoni

NEUROTRANSMITTERS CONTRADICTS
p's without perosnal/family history of depression dont show mood changes after Trp depletion.(lowered seretonin no depression). AAN HET ROT ET AL depressive episode changes seretonin so p's become sensetive to future changes
