Other researchers and doctors agree that this treatment option looks very promising.

About a month ago, Dr. Richter made his debut on WGNO news talking about movement disorders, namely Parkinson's disease, and the current neurosurgical treatments. Deep brain stimulation, a current treatment option for PD, is one of the main procedures that may be discussed on this blog site.

There is no definitive laboratory test to confirm the diagnosis. There are definitive pathological changes in the brain that can confirm the diagnosis, but very few would advocate brain biopsy to determine this earlier in the disease course. There are no proven preventative therapies or "neuroprotective" therapies that would slow the progression of the disease, so treatment centers on symptom reduction. For these reasons, early diagnosis isn't terribly helpful at this point.
Extensive research continues to search for neuroprotective treatments and the early diagnosis tests to make such a strategy effective.

In DBS, a small wire about a millimeter thick (the “lead” or “electrode”) with four different possible stimulation points (the “contacts”) is placed in a very specific spot in the brain. How that spot is determined are for another post on another day, and varies somewhat from situation to situation. Usually the process involves some form of stereotactic targeting and physiologic confirmation. The implanted wire is then pulled under the skin (“tunneled”) to a place where a pacemaker-like device (the “implantable pulse generator” or IPC, also often informally called the “battery”) is implanted, most commonly just under the collar bone (“subclavicular”).
DBS has wide-ranging applications, and is FDA-approved for Parkinson’s disease and Essential Tremor.
There are numerous other movement disorders for which it has been reported to be effective, and it has been used in the past for some complex pain problems. Most recently, it has received considerable attention for certain psychiatric indications, and most experts in the field expect FDA approval for obsessive compulsive disorder (OCD) and major depression in the next several years.
