Default neurofeedback

<You should also be aware that there really isn't a "cure" for head injuries (at least not yet, but maybe in 5 years or so there will be),>

There is no such science to show that we will be able to repair head injuries. The stem cell research for head injuries is finding many problems. The brain in far more complex that a kidney or skin tissue. This science is decades away.

*edit*

I have steps I take to quickly recover from a decompensation. Some times, I can recover in a short time (hour or two). Other times, the decompensation is far more complex and will take more time (days). I have learned how to moderate my environment so that I rarely have the complex decompensations.

The pROSHI is working on a very narrow part of the brain that is accessible through the visual pathways. Modifying the waveform in these pathways have not been shown to modify the waveform in the other brain pathways. As she says, It only works for 10 to 20 hours. The developer claims it just causes a relaxation of the aberrant waveforms.

If you read about the ROSHI and pROSHI and the web site http://www.neurodynamicactivator.com...es/Page345.htm
you will see that the description is 'Excerpted from “Handbook of Neurofeedback” By James R. Evans, Phd '

It talks more about the EM stimulation (Electro-Magnetic) that the light therapy. The pROSHI does not use any sort of feedback technique. It has a chaos oriented program if light timing that has not connection to any realtime QEEG waveforms.

*edit* If you have the money to spend, maybe it is worth a try. $1995 is a good chunk of change.

The pROSHI is a preset system. The therapist does nothing to modify its function for a brain injured patient.

I still take great exception to the claim that LENS and ROSHI/pROSHI is "non-invasive." When the system creates the stimulus by light or EM means, that is invasive. Where is the line separating ECT (electro convulsive shock therapy) from EM stimulating therapy?

Even Davis has admitted that the EM stimulation caused some undesired side effects. I am confused when he connects EM to light as in "Light of EM waves ae presented to the client in a standardized complex (adaptive) mode as mentioned earlier for purposes of entrainment/disentrainment."

Further, he states "Therefore, the pROSHI uses the very advanced concept that the brain itself can become its own neurofeedback device, correcting its own internal errors, given the proper external (proprietary) neurostimulus."

This proprietary claim is confusing. Why is it not patented or protected by US "trade secret" provisions. Sounds like a very low tech company is making some very high tech claims.

Conscious active patient neuro-feedback is non-invasive because it requires the conscious effort of the patient to effect the waveforms. This is a very common form of neurofeedback. It helps the patient to recognize the improper wave forms and adjust, by conscious effort, the focus of the brain. The patient trains using the QEEG brain mapping system and learns how to moderate (reduce) the over powered wave forms by/and increase the underpowered wave forms.

Finding a good neurotherapist with extensive experience with QEEG based neurofeedback for brain injury is important. Most neurofeedback is oriented for the ADD/ADHD student or the athlete trying to maximize his performance. The malfunctioning brain requires a variety of patient efforts to bring the improper wave forms into proper function, if it can be done. Some brains have damage that is not repairable because the usable neural pathways are limited.

Think of the brain's neural pathways like an 88 key piano keyboard. Just to simplify things, I will use simple numbers. 22 keys are the auditory pathways. 22 keys are the visual pathways. 22 keys are the tactile (touch) pathways. 22 keys are the cognitive (thinking) pathways. If any of those keys are damaged, the brain will try to use underused keys from a neighboring pathway system. If the eyes do not work, all of the visual keys become available. This is how the blind get such highly developed auditory and tactile skills. This reassignment of pathways is called neuroplasticity.

The ability of the brain to 'grow' or 'heal' damaged pathways is still not understood. Some believe that the underused pathways that get redirected to another system manifests as healing or regrowth. This is a presumption. The fMRI (functional MRI) studies show increased metabolism is previously low metabolism areas. This could be new growth, new growth, healing, or just underused brain cells getting put into greater service by the brain.

Most neurofeedback tries to encourage these underused pathways to become more functional (rewired). Some people have a greater reserve of underused neural pathways and can quickly turn on these underused pathways. The studies show that this 'rewiring' can happen in as little as 24 to 48 hours.

One of the problems neurophysiology scientists are trying to understand is the suicide tendency of neural pathways. They have observed that right after a brain injury, the fMRI may show weak metabolism or perfusion in a specific damaged area. After some time has elapsed. the damaged areas appear to have shut down. They attribute this to tRNA (transmitting RNA tells cells how to function along a chain of cells) being released that target the malfunctioning cells and pathways to shut down (die). It appear that a margin of weak cells around the more seriously damaged cells also shuts down.

This is the focus of early intervention with stroke victims. Restoring perfusion (blood flow) to the damaged area can lessen this shut down mechanism and lead to better recovery potentials. Even then, rehabilitation therapy is often required to force signals along the weakened pathways or around the damaged pathways based on the concept of neuroplasticity.

Will stem cells help with this problem? The jury is still out. The blood brain barrier gets in the way of getting the stem cells to the damaged areas. If they can program stem cells to grow the vascular structures and brain cells as they would in an infant or small child, this may be possible. It is a long way off. Currently, they are just trying to get stem cells to grow in the brain without causing damage.

btw, I have about a six inches stack of the abstracts of the leading QEEG/neurofeedback studies.

Remember, It is your money to burn by your own choice.
