Graig..NFB 'IS' a 'pretty sketchy science', full stop, and its application
to ADD/ADHD is no exception to this. But the case history evidence suggests
it does actually work in many cases, and that there are many and various
modes that can be effective. To me this is a very intriguing thing and
suggests to me that our models of brain function are not necesarily that
precise, hence our understanding of 'how' NFB works is also not precise.
This not only applies to ADD/ADHD but also to other conditions that are
treatable with NFB.
The most useful model that I have found is the 'arousal' model which
assumes that the psychological condition being treated is due to an over
active neural system that is overly sensitive due to some influence of
other. Hence targeting arousal is a common mode of treatment for a wide
range of disorders, including ADD/ADHD.
There is a great book called 'The synaptic self' by Joseph LeDoux that has
detailed descriptions of the control mechanisms of inter neuronal
communication that involves GABA and Glutamate as inhibitory and
excitational agents and how they interact with other neurotransmitters.
Reading this has given me a much better understanding of the mechanism of
psychological arousal and sensitivity. ie it has provided me with a logical
scientific explanation of the underlying mechanism of psychological
afflictions that involve the arousal pathways. I am sure this same
information is also available from other sources.
We already know from systems theory, that systems that are overly
sensitive, and have inappropriate feedback, tend to be come unstable, and
it is this instability that manifests as a psychological condition. By
altering the external feedback paths, and content, using NFB, and
psychotherapy, the stability of this system can be enhanced, producing a
reduction of symptoms and a more stable personality.
There are a wide range of naturally produced molecular compounds involved
in the regulation of neuronal activity and the levels of these compounds
are under direct control of the system itself, so it makes sense that
an overly responsive system can easily become unstable. Hence the idea
that a NFB session moves the Trainee toward experiencing a new state of
existence that is less activated and more relaxed, ie more stable. With
repeated NFB sessions, this new experience becomes embedded as part of ones
learnt conditioning and is effective on that level.
I don't know if this is any help to you, or even if it is close to reality,
but it is the model that I currently use to explain why NFB works in its
multi-various ways. However, I am not sure that this list is the
appropriate place for this discussion, or even if this uninvited reply is
appropriate, but hey!! isn't this how ADD manifests.
