All these techniques have one common advantage, and that is their non-invasiveness; but, except for neurofeedback, they have the disadvantage that the clinical effect is not lasting, even after repeated treatment sessions, except possibly when the techniques are used as an adjunct, for example in rehabilitation settings. Depending on how long the beneficial effect lasts, the repeated sessions can be performed again or an invasive technique can be applied for longer lasting efficacy. Post neuromodulation changes on functional imaging have been used to claim that correlations between pathology and brain changes are causally related. However, these claims have to be interpreted with care, in order not to fall into a new phrenological trap.
The brain is an information processing machine adjusting itself to the environment. Information processing can be defined as reducing uncertainty. It has been suggested that the brain developed from an evolutionary point of view once living creatures started moving around in a changing and thus uncertain environment.
Dr Natalie Challis has found that effective treatment of Neurobehavioural disorders require a 4 pillared approach: Brain – QEEG and an individualised Loreta Neurofeedback protocol, Body – The clinical application of functional neurology focuses on regulating the activity of the brain, which stimulates changes throughout the nervous system, Behaviour – Working with an educational specialist, and a psychologist, to reinforce the neurological change into behaviour and Balance – Both the gut and brain originate early in embryogenesis from the same clump of tissue, which divides during fetal development.
