Andrew F. Leuchter, MD, is a Professor in the Department of Psychiatry and Biobehavioral Science, Director of the Neuromodulation Division, and a Senior Research Scientist at the Semel Institute for Neuroscience and Human Behavior at UCLA. A graduate of Stanford University, Dr. Leuchter earned his medical degree from Baylor College of Medicine in Houston, Texas. He joined the UCLA faculty in 1986. An internationally recognized expert on the treatment of mood disorders, Dr. Leuchter’s research focuses on the enhancement of treatment outcomes in depression. He directs the Transcranial Magnetic Stimulation (TMS) Service in the Division, which performs more than 2,500 treatments each year for patients with depression, pain, and other neuropsychiatric illness. He is leading clinical trials to develop novel neuromodulation technologies for treatment of depression and Post-Traumatic Stress Disorder (PTSD), including synchronized Transcranial Magnetic Stimulation (sTMS) and Trigeminal Nerve Stimulation (TNS). He uses brain-imaging techniques, such as quantitative electroencephalography (qEEG), magnetic resonance imaging (MRI), and positron emission tomography (PET), to examine brain function and predict which treatments are most likely to benefit individual patients. Dr. Leuchter’s research program combines clinical trials with neurophysiologic and brain-imaging studies to inform clinical practice in the treatment of depression. As a Board certified electroencephalographer, he has unique expertise in development of biomarkers and has shown that brain oscillation patterns can be used to determine highly beneficial and individualized treatment. Dr. Leuchter is a Diplomat of the American Board of Electroencephalography and Neurophysiology and a Diplomat in Psychiatry and Neurology with Added Qualifications in Geriatric Psychiatry. He is a member of several professional organizations, including the American Psychiatric Association, American Psychiatric Electrophysiology Association, and the American Medical EEG Association. He has authored over 150 scientific articles on topics including neuromodulation for the treatment of depression, biomarkers to guide treatment of neuropsychiatric illness, and theories of antidepressant action. He also maintains an active clinical practice, specializing in consultation for and care of patients suffering from treatment-resistant depression.
