Study seeks DBS advancement

DBSDeep Brain Stimulation (DBS) has been around for many years and is one of the most common surgical options for the treatment of essential tremor.  Recently, a new system has been developed that takes DBS to the next level. The new device actually senses and records the brain signals that cause the symptoms of essential tremor and other movement disorders, allowing researchers the opportunity to see exactly what signals are related to abnormal movements.

Although approved for use in the European Union in January, Medtronic’s Activa PC+S system has not been approved by the Food and Drug Administration (FDA) for use in the United States. However, the new device is currently cleared for study in the U.S. and two patients with advanced Parkinson’s disease have already undergone the surgical implantation of the new device.

The hope is that in the near future, this technology will develop to a level where the device itself will monitor the patient’s brain activity and automatically adjust therapy based on the individual’s needs– just as a pacemaker does for heart patients today. This would be a big advancement in DBS if this technology can be developed. Instead of DBS sending a constant, unchanging signal to cancel out tremor symptoms, the device itself would automatically make adjustments and changes to offer patients optimum benefit.

DARPA Focuses on DBS

DBS

Deep brain stimulation (DBS) is a surgical treatment involving the implantation of a medical device called a brain pacemaker, which sends electrical impulses to specific parts of the brain.

The Defense Advanced Research Projects Agency (DARPA) is the agency of the United States Department of Defense responsible for the development of new, advanced technologies in order to maintain the technological superiority of the U.S. military. DARPA recently announced that it will commit $70 million over the next five years to the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) initiative. More specifically, to further investigate Deep Brain Stimulation (DBS).

Deep brain stimulation (DBS) surgery is an FDA-approved treatment that has been proven to significantly reduce the tremor associated with ET. In DBS surgery, a wire (electrode or lead) is placed in the ventral intermediate nucleus (VIM) nucleus of the thalamus, located deep in the brain. The wire connects under the skin to a pacemaker-like device in the chest, which provides mild electrical currents to control symptoms. In ET, DBS of the VIM nucleus of the thalamus is the most commonly used surgical procedure to control tremor.

Advances in technology have now opened up this option for other complex conditions such as depression, which is precisely why DARPA is so interested in the technology.  According to the U.S. Department of Veterans Affairs, 10% to 18% of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) troops are likely to have PTSD after they return from service.  That is a significant number of men and women who may require treatment.

So what does this initiative mean for those affected by essential tremor? DARPA would like to see DBS go further than just treat symptoms. “There is no technology that can acquire signals that can tell them precisely what is going on with the brain,” says Justin Sanchez, DARPA program manager, to The New York Times. He explained that DARPA is “trying to change the game on how we approach these problems.”

DARPA hopes to develop DBS to the point that the device will be able to monitor brain signals in real time, treat illness accordingly and measure the success of that treatment. This would be a real games changer for ET patients suffering from severe tremor symptoms. Imagine never having to turn the DBS device on or off, or have it calibrated. It would be programed to know exactly how to manage individual tremor symptoms, then evaluate the results and make adjustments accordingly.

Only time will tell if DARPA is successful with this ambitious project. But even if all their goals are not realized, they are bound to discover an abundance of new information about how the brain works.

Meet Me in St Louis!

Come spend some time with me and Dr. Pratap Chand Saturday morning, August 17, 2013 from 9:30 – 11:30 am at the St Louis Airport Marriott learning more about essential tremor. Go to www.essentialtremor.org/seminars to register. I look forward to meeting you and together learning about the medications, surgical options and research that is being done in ET.

Come and wear your button and take a picture with me so we can show people where our buttons have been and also to increase awareness around the St Louis area!

Milwaukee ET Event

We had a great time in Milwaukee with 80 people attending the extremely educational ET seminar. The presentations were very well done and provided a lot of information. Dr. Pahapill talked about his 20 year experience in the treatment of ET with deep brain stimulation and Dr. Blindauer reviewed the many medications that are often used and why some may not be successful in the treatment of ET.

Milwaukee Wisconsin here we come!

Hello Milwaukee and surrounding areas!

We will be facilitating another free ET education event/seminar on August 10 in Milwaukee. Come join us as we get together with the ET community to learn more about the diagnosis process and treatments available from Drs. Karen Blindauer and Peter Pahapill of the Medical College of Wisconsin. Follow this link www.essentialtremor.org/seminars  to register online or call toll-free at 888-387-3667. We look forward to seeing you there!

Join Me!

Please join me as I facilitate the upcoming ET Education Seminars on April 20 in Omaha, NE and April 27 in Irvine, CA. More seminars are being scheduled each month so check our website www.essentialtremor.org frequently to see if the IETF will be in your area.

This is a free patient seminar where you will receive some great educational materials and hear some fabulous presentations. To register, go to http://www.essentialtremor.org/Seminars or call our office toll free at 888-387-3667 today!

 

DBS Surgery Treats Violinist’s Tremor

NBC News – Los Angeles
Roger’s passion is the violin, but a neurological disorder called essential tremor (ET) makes it nearly impossible to play. To steady his hands, Roger underwent brain surgery for a procedure called deep brain stimulation that allowed him to play the violin while doctors fired signals into his brain to target the tremors.
