  • April 2018 Research Roundup

    This month’s research report highlights the impact of focused ultrasound across multiple medical specialties. As biomarkers have become critical tools for early detection and treatment of malignant and benign tumors, focused ultrasound could help researchers discover them sooner. A Stanford University team published their findings on a study co-funded by the Foundation. Neuromodulation is a promising non-narcotic solution for treating various types of pain. A University of Washington group conducted a pilot study using focused ultrasound neuromodulation to identify which nerves could be the source of pain in patients with unilateral limb amputations. And finally, it might be possible to use focused ultrasound plus microbubbles to open the blood-brain barrier (BBB) outside of an MRI suite. Biomedical engineers at Columbia University worked to provide effective alternative imaging techniques.

  • Foundation Funded Research Update – Repairing the Parkinson’s Brain

    Parkinson’s disease damages dopamine neurons in the part of the brain called the substantia nigra (SN).

  • News Flash - First Epilepsy Trial


    World's First Focused Ultrasound Clinical Trial for Epilepsy Begins
    Researchers at the University of Virginia (UVA) are starting the first clinical trial in the world using focused ultrasound to treat patients with epilepsy. The study, supported by the Focused Ultrasound Foundation in collaboration with the Epilepsy Foundation, will assess the feasibility, safety and initial effectiveness of focused ultrasound to non-invasively destroy (ablate) diseased brain tissue that causes seizures.
    The study is now recruiting up to 15 adult patients with a range of rare deep brain lesions that produce debilitating seizures that often do not respond to medications.  It is expected that most patients in the study will have benign tumors in the hypothalamus, which can lead to frequent seizures with outbursts of spontaneous laughing, giggling, crying or grunting; developmental delays and/or precocious puberty. The disorder can progress as patients age, leading to increased cognitive decline and severe behavior problems.
    Current options for patients whose seizures do not respond to medication include surgery or laser thermal ablation, both which may involve multiple risks or complications, such as damage to normal brain, infection or hemorrhage.  The only currently available non-invasive method is radiosurgery with the gamma knife, which may take months to show effect, is not image guided and involves risks of complications from radiation.
    “Intractable epilepsy, especially this type, can be devastating and existing therapies have risks and are not uniformly effective, so many patients are in desperate need of better therapies,” says principal investigator Nathan Fountain, MD, professor of neurology at UVA. “If we are successful in destroying the lesions without complications, then this will be an important step on the path toward developing focused ultrasound to enable patients to have freedom from seizures without the risks of open surgery.”
    Dr. Fountain will collaborate with UVA neurosurgeon Jeff Elias, MD, in conducting the procedures using Insightec’s Exablate Neuro System. Patients seeking further information about the study should contact Stacy Thompson, RN at or Nathan Fountain, MD at .
    Momentum Building for FUS and Epilepsy

    “We are committed to advancing the technical, scientific and clinical work required for focused ultrasound to reach its full potential in treating epilepsy,” said Foundation Chairman Neal Kassell, MD.  “This is the first in a planned series of studies in epilepsy that the Foundation is supporting.”

    In addition to the UVA study, the Foundation plans to support a clinical trial led by Neurosurgeon Vibhor Krishna, MD, at Ohio State University using focused ultrasound to ablate the anterior nucleus of the thalamus in patients with partial-onset epilepsy. 

    Neurosurgeon Tomokatsu Hori at Tokyo Women’s Medical University recently applied focused ultrasound to a patient with temporal lobe epilepsy (TLE) to assess feasibility of reaching this target. This is the first step that may ultimately lead to a clinical trial to treat TLE.

  • New England Journal of Medicine Publishes Tremor Results

    The prestigious New England Journal of Medicine published the pivotal study that led to the approval of Insightec’s Exablate Neuro focused ultrasound system to treat essential tremor (ET).


    Sharon Samuels shares her struggle with essential tremor and
    gets her quality of life back after focused ultrasound treatment.

    The ET patients treated in this study achieved significantly reduced unilateral hand tremor that proved durable at 12 months. The procedure also reduced disability and improved quality of life one year after treatment. The study was conducted at eight centers and led by University of Virginia neurosurgeon Jeff Elias, MD.

    “This study represents a major advance for neurosurgery, treatment of brain disease and specifically the treatment of essential tremor,” Dr. Elias said. “For the first time in a randomized controlled trial, we have shown that ultrasound can be precisely delivered through the intact human skull to treat a difficult neurological disease.”

    “This publication further affirms to the medical community that focused ultrasound is a safe and effective alternative to treat the brain without incisions or radiation,” says Foundation Chairman Neal Kassell, MD. “Now that Insightec’s system is approved by the FDA, the important next step is to secure the appropriate levels of reimbursement so that leading medical centers will invest in this technology and make it widely available to patients seeking non-invasive options for their tremors.”

    Given the challenges of accessing the brain and the high cost, complications, and limitations of some current approaches, we believe that focused ultrasound has the potential to revolutionize the treatment of many brain disorders and ultimately to open up opportunities to rapidly advance applications throughout the body.

    The idea of using focused ultrasound to treat tremors was conceptualized at the Foundation's first brain workshop in March 2009. The Foundation then helped organize and fund a pilot study with Insightec and the University of Virginia that served as the predicate for this larger pivotal study.

  • May 2016 Research Roundup

    How do changes in focused ultrasound frequency affect anatomic specificity and efficacy in neurostimulation? Researchers in the US and China both studied this question in mice. A group in France has performed an in vivo, beating heart feasibility study for using focused ultrasound to perform cardiac ablation. Chinese researchers found improved short-term survival in patients treated with focused ultrasound plus chemotherapy when compared with chemotherapy alone for patients with unresectable pancreatic cancer.
