Attention deficit
disorder
(ADD)
and
attention deficit with
hyperactivity disorder (ADHD)
are characterized by one or more of the following: inattention,
hyperactivity, and impulsivity.
Learning disabilities (LD)
are characterized by one or more problems with attention, reading, writing,
speaking, reasoning, memorizing, and problem solving. Further difficulties
may include difficulty organizing and interacting socially.
Many researchers have questioned whether or not attention deficit disorders
can be remedied. Treating children and adolescents with stimulants (usually
Ritalin) has proven to be helpful, but it’s limited by side effects and
tolerance. The introduction of neurofeedback has offered new hope for
parents who want to help their children without the use of drugs.
Neurofeedback research has shown that training brainwave patterns can remedy
attentional difficulties associated with
ADD/ADHD/LD.
Brainwaves and Attentional
Shifting
The brain produces different frequencies for different levels of attention.
They include the following:
Delta - sleep state
Theta - between sleep and awake, also a meditative state
Alpha - relaxed state
Beta 1 - focused concentration
Beta 2 - alert state
Beta 3 - very alert, vigilant
Beta 4 - hyper-vigilant
The ability to produce the right states, especially those associated with
focus and attention, is essential to performing a variety of cognitive
tasks. In addition, the ability to shift from one state to another when
required offers great mental flexibility, which results in enhanced
performance in every area of life.
Using Neurofeedback to Treat
Attentional Difficulties
Neurofeedback, which is a type of biofeedback, has been used for more than
20 years to treat concentration difficulties associated with ADD/ADHD and
LD. In
general, neurofeedback uses an electroencephalograph (EEG) recording system
and training software to enhance the brainwave activity that is instrumental
in
improving concentration.
Neurofeedback is based on research that established that individuals with
poor concentration lack sufficient levels of Beta 1 brainwaves to sustain
attention. (This frequency band is sometimes called SMR, for sensory motor
rhythms.) The findings also showed that individuals with attentional
deficits exhibit excessive amounts of slow brainwave activity, especially
Theta waves. Joel Lubar, a pioneer in this field, demonstrated that
therapies focusing on adjusting the Beta 1/Theta ratio are very effective in
treating children with attention deficits and learning disabilities and
usually result in improved school performance and better behavior control.
During neurofeedback
sessions, the subject responds to feedback from an EEG machine, learning to
increase Beta 1 and decrease Theta. After a certain amount of training,
typically 40 to 60 sessions, the individual is able to produce more Beta 1
at will. Lubar also proved that all children with any form of learning
disability manifested low Beta 1 activity and that many of their symptoms
diminished after a course of brainwave training.
Neurofeedback treatment can also significantly improve intellectual
functioning, as measured by increases in
IQ
scores (Linden, Habib & Radojevic 1996). Such improvement is most likely the
result of the treatment's positive effect on the ability to concentrate.
More recently, Monastra (2002) found that neurofeedback has proven
successful in long-term improvement of ADD/ADHD symptoms. In this study, 100
children, aged six to nineteen years, diagnosed with ADD/ADHD, were
monitored for one year. All children received parental counseling, academic
support, and Ritalin. Half of the children also received neurofeedback
training. After 12 months, all children showed improvement in the ability to
pay attention. However, children who stopped taking Ritalin and had not
trained with neurofeedback lost the gains they had made, whereas those who
had received brainwave training kept their gains even after they stopped
using Ritalin.
