Deep Brain Stimulation

Posted: 4 July, 2007 in Science

Whilst I know most of you probably don’t quite share my passion for medicine, I’m sure anyone would find this interesting!

A few weeks ago I watched saw a video surgery of DBS, but I didn’t know how it actually worked until I recently read more about it in this month’s edition of Popular Mechanics.

Deep brain stimulation involves a small electrode which is implanted into the brain. This electrode gives off electrical pulses, much like a pacemaker does for a heart. This simple setup can do wonders! It can almost completely rid a person of the symptoms of Parkinson’s and other motor diseases. Parkinson’s Disease is a degenerative disease which affects the central nervous system and symptoms are usually impaired large motor function and tremors which can become uncontrollable in advanced cases.

Dr Roger Melvill, a Neurosurgeon from Capetown says this in answer to the question as to why DBS works: “No one knows, all we know is that the electrical stimulus interrupts the neurological pathways in the brain, and that certain neural pathways are affected in movement disorders such as Parkinson’s and essential tremor”

Surgery involves a craniotomy (drilling a hole in the head/cranium to access the brain)The patient is fixed to a “halo” which prevents any head movements, as the patient is awake for the entire procedure in order to ascertain whether or not the operation has been successful and to show when something goes wrong.

The halo is then aimed at the globus pallidus and the electrodes are inserted as the patient is asked to do certain exercises and answer some questions. Things can go wrong, but according to Popular mechanics, this procedure is completely reversible. When the electrode hits the right place, the effect is immediate, and the procedure can completely turn a person’s life around!Isn’t that amazing? Thank God for modern medical science

    Wow! That’s amazing stuff Antz. We really can give God thanks for this procedure and for modern science.

    Whoa! Just imagine! We have people complaining that God is the problem in science today, and yet it’s as if their eyes fail to see a few centimeters deeper. It’s amazing.

    You’re right, it is absolutely mind-boggling to think that people with PHD’s in medicine fail to see intelligent design.
    Romans 1:21-22 ” For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools…”
