  1. Brain Pacemakers Madison Moreau BME 281 September 26, 2012

  2. What Are Brain Pacemakers? • Small battery powered pacemaker that emits electronic impulses • Inserted in affected area of brain • Commonly used in Parkinson’s Disease patients, epileptics, and people who have tremors • Also known as a method of deep brain stimulation • Have over 60,000 customizable options

  3. How Are They Inserted? • Hole is drilled through parietal bone • Small electrodes are placed in area • of brain that needs to be stimulated • Wires are threaded around affected • area, around ears, and down to chest • Pacemaker device is placed near the • center of patients chest

  4. Deep Brain Stimulation • DBS is a surgical treatment that uses brain pacemakers • Treats disorders such as Parkinson’s Disease, chronic pain, depression, tremor, and dystonia • Doctor’s are still unsure of how it works exactly • FDA approved for PD, dystonia and tremor • Serious side effects Ignore metal on maxilla and mandible

  5. History • Brain pacemakers were developed first in France in 1987 • Old treatments used to include burning of the affected tissue • Now small electrodes are placed where the tissue would have been burned away • Their objective is to re-stimulate the area and try to make it respond to normal brain activity

  6. Benefits • Effective, approved way to treat tremor, PD, and dystonia • Used to treat major depression and chronic pain in body • Researched to be used against Alzheimer’s Disease to slow down the progression of the disease • Can stimulate areas of the brain that could not be done in any other way • Decrease in medication

  7. Risks • Like most brain surgery, DBS can be very dangerous • Serious complications include: • Hemorrhage (1-2%) • Infection (3-5%) • Bad probe/ sensors in brain • Sensors become dislodged • Pacemakers need to have their battery replaced • Pacemakers settings can only be changed by reopening the area where the device was implanted

  8. Application on Parkinson’s Disease • DBS does not cure PD – it only slows it down • Used for patients that have several side effects to medication or who’s condition is growing worse on the medication • DBS is programmed to be used only when the brain needs to be stimulated • Not continuously • Normally electrodes are placed in one of three regions: • Subthalamic nucleus • Globus pallidus interna • Zona incerta Insertion of DBS probe

  9. Future • Help cure non-motor diseases • A pacemaker that runs off of the electronic impulses from the body instead of a battery • Become FDA approved for AD, major depression, epileptics and other neurodegenerative diseases • Easier to program without having to perform another surgery • Safer – Less major risks
