Neurofeedback
Neurofeedback or electroencephalogram
(EEG) biofeedback or neurotherapy, is a non-invasive treatment
technique that is used as an adjunctive treatment for
neuropsychological and psychiatric disorders. Neurofeedback utilizes
monitoring electrical activity of the brain with the goal of
regulation and normalization of brain functions. During a
neurofeedback procedure the patient learns to identify and regulate
various brain states (drowsy vs. alert; internal vs. external
attention; anxious vs. calm, etc.) leading to normalization of brain
functions, improvement of symptoms, and development of cognitive
skills and executive functions. Over several sessions, with the use
of systematic techniques and operant conditioning the brain learns
these new skills and generalizes the ability to function more
efficiently as achieved by the training.
Neurofeedback is not a new treatment
model and has been used for about three decades in treatment and
management of disorders such as epilepsy, ADD and ADHD. With more
recent clinical and technical advancements, the therapeutic utility
of these techniques have extended to various other conditions
including mood disorders, depression, anxiety, bipolar disorder,
traumatic brain injury (TBI), post traumatic stress disorder (PTSD),
developmental disorders, autism, tic disorders, and various impulse
disorders.
One of the greatest contributions of
this treatment technique has been in the area of learning disorders,
ADD / ADHD, and more globally, enhancement of cognitive functions
and academic skills. For many parents who had limited choices when
it came to treatment options for such disorders, this method has
proven to offer new options for rapid and relatively permanent
changes in the areas of cognition, behavioral problems, affective
regulation, and social adaptation and function.
In addition, for many adults who have
been suffering from ADD / ADHD, learning disabilities, traumatic
brain injury (TBI), and mood disorders (depression, and affective
disorders), anxiety disorders, the use of neurofeedback in
conjunction with cognitive behavioral therapy and other treatment
interventions used at our center have proven to be a very successful
element in our comprehensive approach to treatment and retraining
brain and autonomic functions.
How is Neurofeedback
done?
A small number of sensors are placed on
different locations on the scalp for monitoring electrical activity
in the brain. The electrical activity is amplified and filtered
based on specific algorithms. Certain aspects of EEG activity are
visualized on the computer screen and the clinician helps the
patient identify and regulate the activity of various aspects of
brain functions as related to attention, mood, stress, relaxation,
vigilance, etc.
Patient learns the correlation between
specific brain states and is operantly conditioned via visual and
audio feedback for successful attempts to regulate brain activity.
Over time patient learn how to regulate brain and specific brain
states leading to improvements in activation or inhibition of brain
areas responsible for aspects of cognitive or affective regulation.
After patient is trained sufficiently over a number of sessions,
these skills are generalized and regulation of these states becomes
effortless and automatic. A range of improvements in cognitive
skills, arousal states, and affective regulation parallel the
training and the improvement in patient's ability to regulate brain
and body functions. These interventions are totally non-intrusive
and side effects are very rare.
