The antidepressant effects of subcallosal cingulate deep brain stimulation (SCC DBS) include acute change in bodily sensation, and the SCC target is connected to cortical regions critically involved in interoception. This study tested whether cortical interoceptive processing is modulated by SCC DBS for treatment-resistant depression.</p><p><strong>Methods: </strong>In 8 patients receiving SCC DBS for treatment-resistant depression, we used electroencephalography to measure the heartbeat-evoked potential (HEP), a putative readout of neural interoception, before surgery and over 6 months of treatment with DBS. We also examined the immediate effect of DBS on the HEP and correlated HEP change over time with outcomes of treatment for depression.</p><p><strong>Results: </strong>HEP amplitude increased from baseline to 6 months of DBS treatment, and this increase was associated with faster antidepressant response.

Overall, modulation of the HEP was most pronounced in sensors over the left parietal cortex.</p><p><strong>Conclusions: </strong>Brain-based evidence implies an interoceptive element in the mechanism of treatment efficacy with DBS for treatment-resistant depression and substantiates a theorized connection between interoception and depression.</p>","PeriodicalId":93900,"journal":{"name":"Biological psychiatry.
