Review Meta Analysis Comparative Study
Combined pharmacotherapy and psychological treatment for depression: a systematic review.
Adherence to antidepressant medication use is a problem in clinical practice. Some authors have posited that combined psychological treatment facilitates adherence to pharmacotherapy. ⋯ Psychological treatment combined with antidepressant therapy is associated with a higher improvement rate than drug treatment alone. In longer therapies, the addition of psychotherapy helps to keep patients in treatment. Further studies are needed to investigate whether the improvement in response attributable to the combination of drug treatment and psychotherapy can be achieved by a combination of pharmacotherapy and a compliance-enhancing intervention.

Comparative Study
Subtype-specific alterations of gamma-aminobutyric acid and glutamate in patients with major depression.
Measurement of cortical gamma-aminobutyric acid (GABA) and glutamate concentrations is possible using proton magnetic resonance spectroscopy. An initial report, using this technique, suggested that occipital cortex GABA concentrations are reduced in patients with major depressive disorder (MDD) relative to healthy comparison subjects. ⋯ The study replicates the findings of decreased GABA concentrations in the occipital cortex of subjects with MDD. It also demonstrates that there is a change in the ratio of excitatory-inhibitory neurotransmitter levels in the cortex of depressed subjects that may be related to altered brain function. Last, the combined data set suggests that magnetic resonance spectroscopy GABA measures may serve as a biological marker for a subtype of MDD.
