In a randomized cross-over design of DBS of the nucleus accumbens (NAc) for treatment refractory methamphetamine use disorder (MUD, n=5), we will test safety, feasibility, effect on clinical outcomes (craving and use), and seek to identify biological targets (using cue craving during recording of local field potentials and MRI).
We will evaluate the effects of deep brain stimulation (DBS) of bilateral nucleus accumbens (NAc) added to background treatment for treatment refractory Methamphetamine Use Disorder (MUD). This is a small randomized cross-over study to demonstrate feasibility and safety, test treatment outcomes (use, craving), and identify novel biological targets (NAc local field potentials (LFP) and functional MRI).
