Helen S. Mayberg (born 1956 in California), is an American neurologist. Mayberg is known in particular for her work delineating abnormal brain function in patients with major depression using functional neuroimaging.[1][2] This work led to the first pilot study of deep brain stimulation (DBS), a reversible method of selective modulation of a specific brain circuit, for patients with treatment-resistant depression. As of August 2019, she has published 211 original peer-reviewed articles, 31 books and book chapters, and acted as principal investigator on 24 research grants. Mayberg is coinventor with Andres Lozano of “Method for Treating Depression Mood Disorders and Anxiety Disorders using Neuromodulation,” US patent 2005/0033379A1. St. Jude Medical Neuromodulation licensed her intellectual property to develop Subcallosal Cingulate Deep Brain Stimulation for Treatment-Resistant Unipolar and Bipolar Depression (SCC DBS) for the treatment of severe depression.[3][4][5] As of 2018, Mayberg holds positions as Professor of Neurology and Neurosurgery and Professor, Psychiatry and Neuroscience, both at Mount Sinai Medical School, and Professor of Psychiatry, Emory University; Emory University Hospital.[6] Since 2018, she has served as Director, Nash Family Center for Advanced Circuit Therapeutics at the Icahn School of Medicine at Mount Sinai.[7][8][9][10][11][12]

Research

Mayberg's research in neurology came about through observations that the psychological diagnoses of mental disorders was not aided by, or backed up by, neurological evidence—and that developing a system of mapping the circuitry of brain activity would allow for more objective diagnoses and treatment.[13][14][15]

Mayberg studies depression and integrates neuroimaging strategies such as Positron emission tomography (PET),[16] sMRI, fMRI, DTI, and EEG as well as behavioral and psychophysiological metrics to define brain mechanisms and testing of antidepressant treatments. She develops imaging biomarkers[17] and algorithms that discriminate patient subgroups and optimize treatment selection in the management of individual patients across all stages of illness. She also concentrates on testing deep brain stimulation for treatment resistant depression, bringing together electro physiologists, engineers, imaging scientists and clinicians to refine, optimize and extend the treatment of depression and other neuropsychiatric disorders.[18]

Since the 1990s, electric stimulation of parts of the brain have been used to treat Parkinsons. The origins of DBS date back to the 1930s.[19][20]

One deep brain stimulation treatment for depression, developed by Mayberg and colleagues, placed electrodes in the Broadmann area 25 of the brain in severely depressed patients. Initial results were encouraging, though clinical trials were deemed futile and ultimately halted; however, there were positive changes in the success rate of the trial after the trial was halted. As a result, she resumed research on her hypothesis.[7] Area 25 is connected to parts of the brain that are related to observable depression traits, such as appetite and sleeping habits. Her hypothesis is sometimes described as a pacemaker for the brain: electronic pulses that correct both the cause and the symptoms of depression.[21] Current research looks into why some patients respond to DBS and others do not.[22] To this end, a study led by Dr. Mayberg showed that brief intraoperative exposure to therapeutic stimulation at the time of implantation surgery induces rapid and consistent electrophysiological brain state change—indexed by a decrease in Beta wave measured at the site of stimulation. These intraoperative brain state changes are seen in individual subjects and are correlated with a significant and sustained reduction in depressive symptoms outside of the operating room without additional stimulation, establishing reduction in beta power as a novel biomarker for DBS treatment optimization.[23]

Meditation and depression

In 2017, Mayberg and the 14th Dalai Lama of Tibet attended a conference on mindfulness and the impact of meditation on the brain. The Dalai Lama was interested in whether the brain impacts the mind or if it might be the other way around. Mayberg pointed out the impact of DBS on severely depressed individuals. Their informal hypothesis was that, based on experiments that examined brain behavior from people practicing meditation, and experiments involving DBS, it was likely that meditation could improve brain waves that are important to mental health — yet when a patient experiences a certain degree of depression, it takes biological treatment to restore the patient to where they can meditate at all.[24][25][26]

Neuroethics

One issue surrounding DBS is that it stands to change a patient’s identity or cause other undesirable emotional or biological conditions. The rebuttal is that severely depressed individuals often have lost a sense of self and that invasive procedures can block the barrier that might be the root cause of the loss of self, thereby restoring it.[27]

Mayberg gave a presentation in 2014 at the Presidential Commission for the Study of Bioethical Issues, where she expressed her clinical and experiential lessons in neuroethics. Her commentary focused on how severely depressed patients are rarely irrational, and that there needs to be open communication and a two-way understanding of expectations. She also asserted in publications that DBS patients should have their own words reflected in the medical literature.[28][29]

Neurolaw

Neurolaw, related to Neurocriminology, is based on the concept that MRI and PET scans as well as other means of examining of a person’s brain composition, can be used to hold harmless an alleged perpetrator in a court of law. Or, conversely, to justify a conviction. Adrian Raine was among those who postulated this theory in the 1980s, and it gained attention in the press after the trial and conviction of John Hinckley Jr.[30][31]

Other scholars, including Mayberg, have argued in editorials and interviews that science of the brain cannot be used, at least at this point, to offer evidence for a conviction. By extension, it could be erroneously interpreted that brain analyses could predict a person’s potential for criminal behavior.[32][33][34]
