Research Interests

As Medical Director, Dr. Regenold is involved in all of the NNU’s research studies. His particular research interests are in the pathophysiology of mood disorders especially related to brain energy metabolism; nutritional, medical and neurologic aspects of psychiatric disorders; the mechanisms of the therapeutic and adverse effects of electroconvulsive therapy (ECT), and the improvement and individualization of noninvasive brain stimulation therapies for major depression including ECT and repetitive transcranial magnetic stimulation (rTMS).
