This is really quite something to behold: A DBS lead with electrodes small enough to potentially stimulate individual neurons. The genius lies in applying the technology used in semiconductor chip design to create a lead with many tiny electrodes that can then be activated and controlled with an extraordinary level of precision.

Looks like a great buy for one of the major medical device manufacturers.

Dr. Ali Rezai, among the country's top functional neurosurgeons and a giant in the DBS field, is leaving the Cleveland Clinic for Ohio State University. Rezai brings a towering reputation and a substantial amount of research funding; he will receives four job titles and a reported $600,000 salary when the move is solemnized at the end of the month.

We will all benefit from this deal if it allows Dr. Rezai to better disseminate his knowledge to colleagues and the broader community. Researcher/clinicians such as Dr. Rezai are pushing the application for DBS technology beyond motion disorders into such areas as epilepsy, obesity, Tourette's (technically a motion disorder). Some potential applications I hadn't heard of: cluster headaches, chronic pain, and addiction.
In Ireland, the system simply sends you across the channel. Why? Finite capacity in the prescribed ranks of neurosurgeons, no doubt. 

Deep brain stimulation surgery is quickly becoming the hot new treatment for an ever-widening array of ailments. Initially approved for treatment of motion disorders such as essential tremor and Parkinson's disease, it was exciting to see the technology applied to other problems, such as epilepsy. Discussion then turned to using DBS for obsessive-compulsive disorder. Since then, we've seen the buzz building around DBS for depression. Humanitarian exemptions have been granted for DBS to treat severe Tourette's. 

This morning's mail brings word of efforts in Canada to extend DBS to people with weight-management problems, and even Alzheimer's disease. Makes me wonder about how DBS might be used by otherwise normal people seeking a cognitive edge, like those who take the ADD drugs.
An article in The New York Times makes a point that might seem self-evident: Patients fitted with heart devices had fewer problems when those devices were implanted by doctors who had special training. I think this finding is very relevant for devices implanted in other areas of the body, particularly in the brain. Consider this point:

Most implant procedures, about 70 percent, were performed by electrophysiologists, the study reported. The remaining implants were done by other types of cardiologists or other kinds of doctors including thoracic surgeons. The study found that the highest rate of serious complications about 2.5 percent, occurred among thoracic surgeons, who accounted for only 1.7 percent of the procedures reviewed.

Knowing this, if one had the choice, why would you *not* want to have a brain implant done by anyone except a specialist with a long track record of performing that specific procedure? I suspect that it is on this point that the surgeons with the record of excellent results differ from those that are merely very good.

The article also provides a strong argument for the creation of a national electronic medical records system. The findings were based on filings made to a national database created in 1995 when Medicare and Medicaid agreed to paying for more implanted defibrillators. One can only imagine the other bits of hard science to be gleaned from records based on data from millions of eople.
