Neurological Biomarkers May Eventually Predict Response to Antidepressants

February 13, 2012 · Posted in Risk Factors 

brainT.L. Lauriat reported at the 51st Annual Meeting of the National Institute of Mental Health’s New Clinical Drug Evaluation Unit (NCDEU) in 2011 that low baseline levels of the neurotransmitter GABA in the brains of depressed patients were associated with greater response to antidepressants. GABA was measured using magnetic resonance spectroscopy (MRS).

These data raise the possibility that easily observed neurobiological markers, such as levels of GABA or the neurotransmitter glutamate, may ultimately be helpful in predicting clinical response to particular treatments.
