This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue.<\/p>\n\n\n\n<p><strong>How it Works<\/strong><br>Where the beams converge, focused ultrasound produces two therapeutic effects that are being evaluated.<\/p>\n\n\n\n<p>One mechanism is to temporarily open the blood-brain barrier (BBB) which can facilitate the introduction of therapeutic genetic material. The BBB closes shortly after sonication ends.<\/p>\n\n\n\n<p>Another mechanism is to use neuromodulation that would enhanced release of Brain Derived Neurotrophic Factor (BDNF) which has reduced the impact with Rett Syndrome animal models. While significant preclinical work has been accomplished, there is still much to be done before either technology will be widely available.<br><br><strong>Advantages<\/strong><br>Existing therapy for Rett Syndrome is supportive and symptomatic.<br><br>For certain patients, focused ultrasound could provide a noninvasive alternative therapy with less risk of complications \u2013 such as surgical wound healing or infection \u2013 at a lower cost. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-clinical-trials\">Clinical Trials<\/h2>\n\n\n\n<p>At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of Rett Syndrome.<\/p>\n\n\n\n<p>The Foundation updates these pages regularly, but with the increasing number of clinical trials, we want to be sure that our audience has the latest information available.
