Title | The impact of theta-burst stimulation on cortical GABA and glutamate in treatment-resistant depression: a surface-based MRSI analysis approach |
Overall design | The aim of this study was to expand insights into the therapeutic effects of theta burst stimulation on the GABAergic and glutamatergic system utilizing 3D-multivoxel magnetic resonance spectroscopy imaging (MRSI) in combination with a novel surface-based MRSI analysis approach to investigate changes of cortical neurotransmitter levels in patients with treatment-resistant depression. Twelve treatment-resistant depression patients completed paired MRSI measurements, using a GABA-edited 3D-multivoxel MEGA-LASER sequence, before and after 3 weeks of bilateral theta burst stimulation treatment. Changes in cortical distributions of GABA+/tNAA (GABA+macromolecules relative to total Nacetylaspartate) and Glx/tNAA (Glx = mixed signal of glutamate and glutamine), were investigated in a surface-based region-of-interest (ROI) analysis approach. |
