The conference included daily lectures followed by hands-on experience in TMS-interleaved fMRI, methods for advanced TMS-EEG, and simultaneous TMS-EEG-fMRI. Background: Transcranial magnetic stimulation (TMS)-evoked potentials (TEPs), recorded using electroencephalography (TMS-EEG), offer a powerful tool for measuring causal interactions in the human brain. His interest is in using advanced functional neuroimaging tools to define causal neural circuit pathways in the brain in health and disease. pROC: an open-source package for R and S + to analyze and compare ROC curves. Amit Etkin, MD, PhD ... As such, collecting EEG data in the context of sufficiently large clinical trials, when analyzed through AI, enables us to find patterns of brain activity that predict treatment outcome, even if such patterns are themselves too hard to read “by eye” from the data. A Revolution In Depression Treatment. ABOUT. “Brain stimulation is a costly and somewhat burdensome … Machine-learning study finds EEG brain signatures that predict response to antidepressant treatments. In this new Nature study, senior author Amit Etkin, a psychiatry professor at Stanford University, ... EEG uses a cap with electrodes fixed to a person's scalp to record the activity of neurons. However, the test-retest reliability of TEPs, critical to their use in clinical biomarker and interventional studies, remains poorly understood. Our findings are exciting because they reflect progress made toward this clinical goal, and they also show the potential of bringing sophisticated data analytic methods to psychiatry,” explained senior author Amit Etkin, M.D., Ph.D., a professor of psychiatry and behavioral sciences at Stanford University and CEO of Alto Neuroscience, Los Altos, California. Amit Etkin Current methods for diagnosing depression are simply too subjective and imprecise to guide clinicians in quickly identifying the right treatment, Etkin said. Exploring novel metrics of the EEG signal could yield better results. 12, 77 (2011). AI Tools. – Brain-wave pattern can identify people likely to respond to antidepressant, study finds (Stanford Medicine press release): “A new method of interpreting brain activity could potentially be used in clinics to help determine the best treatment options for depression, according to a study led by researchers at the Stanford School of Medicine. Abstract Concurrent single‐pulse TMS‐EEG (spTMS‐EEG) is an emerging noninvasive tool for probing causal brain dynamics in humans. Article Google Scholar Amit Etkin. In addition to a variety of antidepressants, there are several other types of treatments for depression, including psychotherapy and brain stimulation, but figuring out which treatment will work for which … Robin, X. et al. BBC. All of the participants had an EEG before starting the drug or placebo. Amit Etkin, MD, PhD Professor of Psychiatry. News. Etkin said the "AI tool was quite effective" at predicting which patients would do well on the medications. The study suggests that electroencephalography, or EEG, could one day be used to help predict whether someone will respond to an antidepressant. Instead of functional magnetic resonance imaging, an expensive technology often used in studies to image brain activity, the scientists turned to electroencephalography, or EEG, a much less costly technology. Stanford's Professor Amit Etkin heads a large team that used electroencephalography, better known as EEG, to measure the brainwaves of people … Correspondence Amit Etkin, 401 Quarry Road, MC 5797, Stanford, CA 94305, USA. author = "Paolo Belardinelli and Mana Biabanimoghadam and Blumberger, {Daniel M.} and Marta Bortoletto and Silvia Casarotto and Olivier David and Debora Desideri and Amit Etkin and Fabio Ferrarelli and Fitzgerald, {Paul B.} "While work remains before the findings in our study are ready for routine clinical use, the fact that EEG is a low-cost and accessible tool makes the translation from research to clinical practice more … Network functional ... A total of 221 participants underwent EEG recordings and provided high-quality pretreatment EEG data. The current study included more than 300 patients with depression. “EEG readouts provide a direct measurement of brain electrical activity,” noted Amit Etkin, M.D., Ph.D., a professor of psychiatry and behavioral sciences at Stanford University. 3. "An EEG is a simple and relatively cost-efficient strategy that could prove to be highly beneficial in the long run," he said. This imprecise method contributes to a general perception that antidepressants are ineffective, added Dr. Amit Etkin, study co-author and a professor of psychiatry at Stanford University. Amit Etkin is a human systems neuroscientist and psychiatrist. The new technology uses a readily available, low-cost test called the electroencephalogram (EEG). The study, entitled “Identification of psychiatric disorder subtypes from functional connectivity patterns in resting-state electroencephalography (EEG)” was led by Stanford University professor of psychiatry and behavioral sciences, Amit Etkin, MD, PhD, and received major funding from CVB. The key methodology is summarized below, focusing on the collection and analysis of TMS- Concurrent single-pulse TMS-EEG (spTMS-EEG) is an emerging noninvasive tool for probing causal brain dynamics in humans. Using the spTMS‐EEG data described above, we benchmarked ARTIST against MARA (Winkler et al., 2011), which is a state‐of‐the‐art supervised IC rejection algorithm developed for cleaning standard EEG data, to determine IC classification accuracy, with manual artifact rejection results by the EEG experts as the gold‐standard. The goal was to obtain a baseline measure of brain-wave patterns. EEG alpha asymmetry as a gender-specific predictor of outcome to acute treatment with different antidepressant medications in the randomized iSPOT-D study Martijn Arnsa,b,⇑, Gerard Bruderc, Ulrich Hegerld, Chris Spoonere,f, Donna M. Palmere,f,g, Amit Etkinh,i, Kamran Fallahpourc,j, Justine M Gattg,k,l, Laurence Hirshbergm, Evian Gordone,f According to Etkin, Trivedi, Wu, and colleagues, the present research highlights the potential of machine learning for advancing a personalized approach to treatment in depression. Etkin, who is on leave from Stanford working as founder and CEO of the startup Alto Neuroscience, is the senior author. We are pleased to present this archive of recorded presentations from the meeting to share with the Neuromodulation for Rehabilitation community. and Kimiskidis, {Vasilios K.} and … Dr. Amit Etkin, CEO of Alto Neuroscience and Professor of Psychiatry and Behavioral Sciences at Stanford University, discussed research using machine learning to predict potential drug efficacy in patients with depression and guide treatment decisions. Amit Etkin on EEG as a Tool in Depression Treatment. Etkin shares senior authorship of the paper with Madhukar Trivedi, MD, professor of psychiatry at the University of Texas-Southwestern. info@altoneuroscience.com. An EEG shows specific patterns of brain activity that can be used to train a machine-learning algorithm. and Alex Fornito and Gordon, {Pedro C.} and Olivia Gosseries and Sylvain Harquel and Petro Julkunen and Keller, {Corey J.} About Amit Etkin, MD, PhD is the Founder and CEO of Alto Neuroscience, and Professor (on leave to Alto) in the Department of Psychiatry and Behavioral Sciences at … Amit Etkin. During an EEG, electrodes are placed all over the head. To identify subtypes, the researchers used electroencephalogram, EEG, to collect brainwave data from 201 participants -- 106 with PTSD and 95 healthy controls. And, much like a drug that treats one type of breast cancer doesn't work well on another, Etkin said that people "shouldn't think of antidepressants as one-size-fits-all." LINKS. Email: amitetkin@stanford.edu. ... (TMS) while imaging the consequences with concurrent fMRI or EEG. They were randomly selected to receive either sertraline or a placebo. Home. First, the researchers collected EEG data on the participants before they received any drug treatment. BMC Bioinform. Reuters. For their study, Etkin and his colleagues set out to find a brain-wave pattern to help predict which depressed participants would respond to sertraline. Cortical Connectivity Differentiates Antidepressant From Placebo Response. “fMRI measures blood flow, which is only an indirect measurement of brain activity.” The team at Stanford University led by Dr. Amit Etkin paired Hans Berger 1924 discovery of electroencephalogram (EEG) to measure brain activation in depressed patients and use Artificial intelligence (AI) and machine learning models to predict treatment response to the commonly prescribed antidepressant sertraline (Zoloft).
By analyzing brainwaves, researchers have identified two clinically relevant subtypes of major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) that may respond differently to psychotherapy, antidepressants, or brain stimulation in findings that could accurately pinpoint optimal treatment at diagnosis.
