Here's a brief summary of some of the things we discussed at the 10/3/2007 meeting. 1. Dr. Obeid talked about the patients he met last week at the USC Biomimetic Microelectronics Center. 2. We discussed some of the theories behind why deep brain stimulation worked. Dr. Peridier wondered if it wasn't related to the phenomenon where dental (or jaw) pain can be reduced by listening to music - a bandwidth sharing issue perhaps? 3. We discussed the potential ethical issues behind implanting a patient with a medical device such as DBS whose means of efficacy is poorly understood. 4. Item 3 led us to wonder how drugs like aspirin and ibuprofen work. We resolved to look at the issue for our next meeting.

Other applications of DBS include: Parkinson’s disease, Dystonia, Multiple Sclerosis, Phantom Limb Pain, Depression, Tourette, Obsessive-Compulsive Disorder and other serious psychiatric disorders.

Risks/Challeges:
The electrodes are placed in the subthalamic nucleus, and are attached to a wire passed under the skin to a battery (stimulator), which is placed under the collarbone (during a separate surgery). The stimulator is not turned on until the brain has healed (few weeks). A simple magnet can turn off the stimulator.
The most obvious risk to me is getting close to any magnetic field. Patients with DSB implants should also avoid MRI.

Interesting fact:
There are more than 35,000 DBS implants worldwide.
