Some of you have heard of doctors' using electro-magnetic pulses to treat persons with depression, right? Basically, the pulses keep electrons from moving in the part of the brain they're held over, so that when the device is stopped, the patient's brain has more or less been 'rebooted' (without erasing
memory, of course; otherwise they couldn't do it), so they feel much better than before (this may be due to the halted production, and dissipation, of depression-causing chemicals in the brain).
My thinking is to adapt this to coma patients: give their brain a restart, and maybe they'll wake up.
We'll never know whether it works unless someone actually does it.
For clarity, this is >NOT< shock treatment.

"We'll never know whether it works unless someone actually does it." - well, can we test it on you? |
|
| |
Google "transcranial magnetic stimulation". |
|
| |
Since this is not shock treatment, I have deleted [DrCurry]'s link regarding it, as it is way off-topic. |
|
| |
shock - deleting DrC's links - shock |
|
| |
It does, with varying degrees of success, of course. The question is what effect it will have on coma patients. As far as I can tell, nobody's tried it on a single one. |
|
| |
I have got to believe this has been tried. As long as electroshock therapy has been around, someone _has_ to have had this idea before. |
|
| |
My comment, until galuka pointed out s/he wasn't talking about ECT, but PMFC. However, my first link stated that ECT leads to coma, so you would be putting out the fire with gasoline. |
|
| |
I haven't heard the term PMFC, but I have heard TMS (trans-cranial magnetic stimulation). Probably the same thing, but TMS is specifically for the brain. |
|
| |
There isn't a little button round the back that you prod with a bent paperclip, then ? |
|
| |
Coma can arise from a number of different causes; surely we need to understand the specifics of the cause before a treatment is applied ? |
|
| |
Aha! but what about a comatose kitty? |
|
| |
I agree that not all comas need the same treatment. However, if the patient doesn't wake up even *after* being physiologically stabilized, it's probably safe to assume there's a problem in the brain. |
|
| |
For purposes of being reasonable, I believe this treatment would be for patients who have been comatose for a while, and no one figures they're going to wake up themselves. |
|
| |
The treatment is, as far as everyone knows, not permanent, non-invasive, and completely painless. I say, as long as they've no hope of waking up anytime soon, you might as well *try* it at least. |
|
| |
[bliss], I will say it again: this is <*NOT*> ECT, shock treatment, electroshock treatment, or ANYTHING that involves passing electric current through the body. |
|
| |
TMS may be young, but it is still non-invasive, non-permanent, and non-damaging. Just because it hasn't been tried doesn't mean it won't work. |
|
| |
Even if it wasn't very effective, if it woke only one person up, it would be better than letting them vegetate forever, wouldn't it? It's something to *try*. |
|
| |
If it only woke one person up, it would be more economically efficient to hire Britney Spears to sing at the coma patients' bedside. Hearing celebrities voices has also been effective at rousing people from comas. |
|
| |
There don't seem to be health risks associated with magnetic fields, although they can affect chemical reactions in the body (see link: the National Radiation Protection Board says "there is no direct experimental evidence of any acute, adverse effect on human health due to short-term exposure to static magnetic fields up to about 2 T [2000 milliTeslas]... Effects on behavior or cardiac function from exposure to much higher magnetic flux densities than 2 T [2000 milliTeslas] cannot be ruled out... "). However that does not mean this therapy is guaranteed to be "non-permanent and non-damaging". |
|
| |
I am sure this idea is meant well, but brains are not electrical devices: they have a complex bio-chemistry which is not going to be meaningfully affected by magnetic pulses. |
|
| |
// Britney Spears to sing at the coma patients' bedside // |
|
| |
That isn't "treatment", it's "cruel and unusual punishment". |
|
| |
// Britney Spears to sing at the coma patients' bedside // |
|
| |
This may not wake up my brain, but it would wake up another part of my anatomy... |
|
| |
I mis-read this as Robot Coma Patients Brains. I envisioned a whole army of comatose robot slaves. |
|
| |
[pottedstu], I believe you meant that brains are not *only* electrical devices. |

Once I decided to write a book. Not a good book, it turned out, ‘cause everything I tried to write was…. well, something. The only juicy stuff came out of my deep subconscious. Trouble was, I couldn’t tap the juice whenever I wanted to. I had to be jogging, or doing some other skill thing. And I don’t have many skills, sadly. So, except for running around the block <exhausted>, I was in deep writer’s block. The whole book thing languished until I had the idea of using some of these newfangled transcranial magnetic stimulators -- wiring ‘em into a mortarboard I found in the closet to make a “thinking cap”. Now, if you set in on your head just right you can stimulate the cerebellum -- that’s the bumpy thing on the back of your brain that you use to run and stuff. Well, heavens! Here I sit with my thinking cap on, my feet twitching and squirming to beat all, and I’ve got all these ideas! So, back to my book -- let’s see now...page 2. |

I dunno about that. What I've heard about TMS is that its powerful magnetic fields paralyze electrons, preventing electrical activity from taking place in whatever part of the brain it's held over, and that without touching or harming the cells themselves. The reason it might work on coma patients is that, perhaps, their brains aren't functioning normally and are stuck in an infinite loop. Stop activity in the part that's stuck for a while, then maybe it'll restart correctly when you let off. |
|
| |
This could still be done for you, though it'd hafta be done differently (and away from the computer). Just get an MRI (or just ask someone) to find what part of yer brain comes up with the writing ideas. Then 'paralyze' the other part of yer brain. The creative part will then become more active, sensing the suppression of the other part, and you'll get more ideas. This type of thing was done to regular people in a clinical trial. |
|
| |
Their 'creative-artistic' side was disabled temporarily in this manner, and their 'analytical' side became dominant. They became clairvoyant (human calculators) for the duration of the session. They did about 10 of these sessions. About one-fifth became permanently clairvoyant, presumably because their 'analytical' side had learned how to make itself manifest at any time. |
|
| |
// paralyze electrons… became clairvoyant//
Pluterday, turned into a deep thinking clairvoyant human calculator, her electrons completely frozen by too much magnetic stimulation, managed to say this: “forty two”. <That’s the right answer all right, but she may have cheated.> |
|
| |
coma-survivors, cognitive potentials are more frequently obtained when using stimuli that are more ecologic or have an emotional content (such as the patient's own name) than when using classical sine tones. |
|
| |
this strongly suggests that zapping a memory center like the hippocampus along with a pleasure center would make a potential coma treatment; rather than a reboot a bunch of happy memories might wake them up |
|
| |
plus it seems kind to stimulate the pleasure centers of the eeg active comatose |
|
| |
For the record, I've never heard of
electromagnetic pulses working very well
to treat depression. ECT *is* used for
intractable depression, and it is not
particularly unpleasant, though it's not
what you'd try first. |
|
| |
Whether ECT or non-contact ECT would
work for coma patients, I have no idea. I
would be very surprised, though, if it
hasn't been tried. |
|
| |
ECT is not tried first because of that cuckoo movie, and bad press encouraged by the pill people. It is another example of a nonpharmacologic treatment superseded by a pharmacologic treatment because of the love of things pill. |
|
| |
Precisely so. To be fair, though, in an
unbiased choice, 9 out 10 customers
preferred the pills. |
|
| |
i wonder if *rebooting* would rectify some forms of autism. |

Well that was poignant. My heart skipped a beat when i read that. |
|
| |
Is it still poignant if one is from South Dakota and pronounces it with a hard G? |
|

This has been tried. Almost everything has been tried. The issue is not a matter of needing a reboot, but to extend the metaphor, the fact that the boot sector is missing or garbled without a method for restoring the basic "software" for consciousness the brain will simply remain basically inert. Treatment for most comatose patients fails because we simply do not understand exactly what is missing. (like trying to start a car that has no distributor, no amount of cranking or starting fluid is going to make it run.) |
