Deep Brain Stimulation as Depression Treatment

Neopallium writes "Medtronic, today announced its intentions to pursue a major clinical trial of the company's deep brain stimulation (DBS) technology in the treatment of severe and intractable depression, a disabling form of the psychiatric disorder affecting millions of people worldwide. "While not a cure, DBS has allowed these patients to return to much more functional and happy lives," said Dr. Rezai, who represented an international working group of physicians that has been studying the application of DBS therapy in the treatment of intractable depression and OCD in collaboration with Medtronic."

Re:Unexpected side-effects

You've got to remember that this will probably be used (at least at first) as an alternative treatment of major depression for when traditional (chemical) treatments do not work. It will most likely be used when the illness is debilitating, where the sufferer cannot function. Creating works of art (or performing any task which requires intense concentration) in a depressed state implies that there's a modicum of function. I know of people that cannot even put a single sentence together when they're most depressed.

As someone with bipolar disorder, I welcome any further additions to the repertoire of weapons we have against serious depression. I just hope no one in the trials commits suicide, a common occurrance of people who are just beginning to have their depression lifted.

The Original Clockwork Orange

[Baldrson]

Anthony Burgess, author of the book "A Clockwork Orange" was the artist in residence while I was in the undergraduate program at the Iowa City Writer's Workshop back in 1974. I think he based his book on the work of Jose M.R. Delgado, M.D. published under the book with the damn spooky title: "Physical Control of the Mind: Toward a Psychocivilized Society".

I managed to get a copy of the book finally, and discovered wonderful passages such as the following on page 115:

ESB [electrical stimulation of the brain -- JAB] may evoke more elaborate responses. For example, in one of our patients, electrical stimulation of the rostral part of the internal capsule produced head turning and slow displacement of the body to either side with a well-oriented and apparently normal sequence, as if the patient were looking for something. This stimulation was repeated six times on two different days with comparable results. The interesting fact was that the patient considered the evoked activity spontaneous and always offered a reasonable explanation for it. When asked, "What are you doing?" the answers were, "I am looking for my slippers," "I heard a noise," "I am restless," and "I was looking under the bed." In this case it was difficult to ascertain whether the stimulation had evoked a movement which the patient tried to justify, or if an hallucination had been elicited which subsequently induced the patient to move and to explore the surroundings.

This passage is eerily reminiscent of a passage from Richard Dawkins' "The Extended Phenotype" chapter titled "Host Phenotypes of Parasite Genes":

"Many fascinating examples of parasites manipulating the behavior of their hosts can be given. For nematomorph larvae, who need to break out of their insect hosts and get into water where they live as adults, '...a major difficulty in the parasite's life is the return to water. It is, therefore, of particular interest that the parasite appears to affect the behavior of its host, and "encourages" it to return to water. The mechanism by which this is achieved is obscure, but there are sufficient isolated reports to certify that the parasite does influence its host, and often suicidally for the host... One of the more dramatic reports describes an infected bee flying over a pool and, when about six feet over it, diving straight into the water. Immediately on impact the gordian worm burst out and swam into the water, the maimed bee being left to die' (Croll 1966)."

Just have to let everyone know, I also met my partner in the 'Psych Ward' of a local hospital.

It certainly helps when you have someone around who understands why you feel the way you do at times. Although, the reverse is also true if you both forget to take your meds at the same time.... hehe, nasty.

Anyways, she has just given birth to our first child together (its a girl).

Hopefully, she wont suffer the same problems as her parents, but if she does... well hopefully we have the understanding to help her overcome some of the issues, or at least support her during the harder times.
