Andrew Leuchter, MD Director, Neuromodulation Division

Andrew F. Leuchter, MD, is a Professor of Psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA. He also is Director of the Neuromodulation Division and a Senior Research Scientist at the Semel Institute. Dr. Leuchter is a graduate of Stanford University and the Baylor College of Medicine who joined the UCLA faculty in 1986.

The Neuromodulation Clinical and Research Service performs approximately 2,500 transcranial magnetic stimulation (TMS) clinical treatment sessions per year, primarily for patients with unremitting symptoms of Major Depressive Disorder (MDD). Treatment is delivered utilizing the Neuronetics Neurostar system, which is FDA-approved for treatment-resistant MDD. This program also provides treatments for conditions that frequently are comorbid with MDD, including chronic pain and anxiety. All patients receive comprehensive evaluation of symptoms over the course of treatment. The TMS Program integrates comprehensive longitudinal symptom assessment, cognitive performance tasks, and brain neurophysiologic monitoring to allow for the collection of research-level data from patients undergoing clinical treatment who elect to participate as research subjects. Treatment parameters including brain site and pulse parameters will be evaluated alongside clinical and neurophysiologic measures to investigate potential evidence for refining treatment protocols based upon specific patient characteristics. The clinical program currently utilizes a standard form of repetitive TMS (rTMS) delivered via an FDA-approved system. The program soon will launch use of investigational pulse sequences such as “theta burst stimulation” (TBS) using the Neuronetics’ XPLOR system, which will allow a variety of different research treatment paradigms including sham-controlled studies. The XPLOR is system is currently being configured to undertake a double-blind sham-controlled study of TBS for the treatment of MDD. A different neuromodulation technology, Trigeminal Nerve Stimulation (TNS), is currently under study at the Greater Los Angeles Veteran’s Administration as a novel treatment in veterans with Post Traumatic Stress Disorder (PTSD). This aim of this project, funded by the Department of Defense, is to determine whether adjunctive treatment with active TNS is more effective than sham TNS for reducing symptoms of stress, anxiety, and depression among veterans with PTSD.

Marc Heiser MD, PhD

Dr. Heiser’s primary research interest is clinical systems neuroscience that aims to identify treatment intervention targets. He is currently working with Dr. Marco Iacoboni and Dr. Carrie Bearden using transcranial magnetic stimulation (TMS) and fMRI to examine the mirror neuron system and its relation to social cognition in patients at high risk for psychosis (supported by the AACAP Pilot Research Award). To further explore his interest in the neurobiology of social cognition in psychiatric illness, he is developing a project with Dr. James McCracken to use TMS as an intervention to enhance imitation and social cognition in patients with Autism Spectrum Disorder (ASD).

Combining neuroimaging with TMS will allow us to understand the neural pathways that are disrupted in neurodevelopmental disorders such as ASD and to alter those pathways in order to remediate core deficits. Ultimately, his plan is to develop an integrated clinical research pediatric neuromodulation program to treat a wide range of psychiatric disorders in children and adolescents.

Although medications are generally safe and effective for treatment of ADHD, considerable concerns remain over side effects and many parents are ambivalent about their use. While there is great demand for non-medication approaches to ADHD, the most popular alternatives are not based on any scientific understanding of how the brain works and have no scientific evidence to support their use. Brain imaging studies on adults with medication-resistant epilepsy and depression revealed brain activation in areas involved in attention and executive functioning, regions implicated in ADHD. Based on these findings, their group conducted a preliminary investigation of TNS in children and found that treatment was safe and associated with significant improvements in behavioral and laboratory measures of ADHD.

All participants who demonstrate significant improvement on active TNS, either during the randomized trial or with open therapy, will be eligible for one year of active TNS to help manage their ADHD.

The Attention-Deficit/Hyperactivity Disorder (ADHD) program conducts neuromodulation research seeks to develop a better understanding of childhood emotional and behavioral disorders, as well as to develop new treatment approaches. Their current research project is a three-year clinical trial of Trigeminal Nerve Stimulation (TNS) for ADHD in youth ages 8-12 years that is intended to help design future studies that could lead to FDA approval as an ADHD treatment. The project is a four-week, double blind, randomized trial of active vs. sham (inactive) TNS followed by one week of follow-up after treatment is stopped. Participants who are randomized to the sham treatment will be eligible for four weeks of open treatment with active TNS following the blinded trial. All participants who demonstrate significant improvement on active TNS, either during the randomized trial or with open therapy, will be eligible for one year of active TNS to help manage their ADHD.

Although medications are generally safe and effective for treatment of ADHD, considerable concerns remain over side effects and many parents are ambivalent about their use. While there is great demand for non-medication approaches to ADHD, the most popular alternatives are not based on any scientific understanding of how the brain works and have no scientific evidence to support their use. Brain imaging studies on adults with medication-resistant epilepsy and depression revealed brain activation in areas involved in attention and executive functioning, regions implicated in ADHD. Based on these findings, their group conducted a preliminary investigation of TNS in children and found that treatment was safe and associated with significant improvements in behavioral and laboratory measures of ADHD.
