An Update on the Use of Neuromodulation Strategies in the Treatment of Schizophrenia.

The field of neuromodulation has evolved tremendously and now includes a vast array of interventions utilizing different technologies that span electrical, magnetic, and ultrasound forms of stimulation. The evolution of interventions holds the promise of fewer adverse effects and a noninvasive approach, increasing the scale at which these interventions may be offered in hospital and community settings. While the majority of neuromodulation studies have focused on patients with mood disorders, predominantly depression, there is an unmet need for patients with schizophrenia, who are in dire need of novel therapeutic options. Advances in neuroimaging and approaches for examining individual variability and transdiagnostic symptoms may lead to more effective neuromodulation treatments in this patient population. This overview explores the modern landscape of invasive and noninvasive neuromodulation treatments for patients with schizophrenia. It begins with approaches that involve diffuse stimulation of the cortex and subcortex and then reviews more focal stimulation approaches at the cortical and subcortical levels. The authors also reflect on the relationship between our understanding of the neurobiology of schizophrenia and neuromodulation interventions.
