![]() | ADHD: Brain Training, Neurofeedback, Diet, and More. |
ADHD,
or attention deficit hyperactivity disorder, affects millions of
children and adults (up to 5% of children in the US). More and
more evidence suggests that brain training may be key to help these
individuals. With this in mind, we put together our most recent articles
on the topic to a) help you better understand what is going in
the brain of a person with ADHD, and b) provide you with up-to-date
information on what can be done to fight the disorder and improve the
lives of people suffering from it. We particularly thank Dr. Rabiner
from Duke University for writing many of these articles.

Neurofeedback:
Another
Treatment for ADHD
In just the last 20 years, Attention Deficit %26 Hyperactive Disorder,
(ADHD) has become America's leading childhood psychiatric disorder. Approximately
2% to 6% of school-age children are diagnosed with ADHD (Raz
2004).According to Barkley (1998) the number of children
affected by ADHD can vary from 1% to 20 %, depending on how one chooses
to define it, the population studies, the geographic locale of the
survey, etc. ADHD is characterized by the inability to self-regulate
focused attention. Children with hyperactivity are impulsive and
behaviorally disinherited. The condition is developmentally disabling
which, if left uncontrolled persists into adolescence and adulthood
(Edwards, 1995).

Neurofeedback
Gains Popularity and Lab Attention (New York Times)
The treatment is also gaining attention from mainstream researchers,
including some former skeptics. The National Institute of Mental Health
recently sponsored its first study of neurofeedback for A.D.H.D.: a
randomized, controlled trial of 36 subjects.
The results are to be announced Oct. 26 at the annual meeting of the
American Academy of Child and Adolescent Psychiatry. In an interview in
the summer, the study’s director, Dr. L. Eugene Arnold, an emeritus
professor of psychiatry at Ohio State, noted that there had been
“quite a bit of improvement†in many of the children’s behavior,
as reported by parents and teachers.

The
Heart Chamber Orchestra consists of classical musicians who use their
heartbeats to control a computer composition and visualization
environment. To my best knowledge, this is the first example of "group
biofeedback". The musicians are equipped with ECG (electrocardiogram)
sensors. A computer monitors and analyzes the state of these 12 hearts
in real time. The acquired information is used to compose a musical
score with the aid of computer software. It is a living score dependent
on the state of the hearts. While the musicians are playing, their
heartbeats influence and change the composition and vice versa. The
musicians and the electronic composition are linked via the hearts in a
circular motion, a feedback structure. The emerging music evolves
entirely during the performance. The ... | |

![]() | Neurofeedback Outcomes in Clients with Asperger's Syndrome |
Authors:
Thompson L, Thompson M, Reid A This paper summarizes data from a review
of neurofeedback (NFB) training with 150 clients with Asperger's
Syndrome (AS) and 9 clients with Autistic Spectrum Disorder (ASD) seen
over a 15 year period (1993-2008) in a clinical setting. The main
objective was to investigate whether electroncephalographic (EEG)
biofeedback, also called neurofeedback (NFB), made a significant
difference in clients diagnosed with AS. An earlier paper (Thompson et
al. 2009) reviews the symptoms of AS, highlights research findings and
theories concerning this disorder, discusses QEEG patterns in AS (both
single and 19-channel), and details a hypothesis, based on functional
neuroanatomy, concerning how NFB, often paired with biofeedback (BFB),
might produce a change in sympto... | |

Authors:
Repetto C, Gorini A, Algeri D, Vigna C, Gaggioli A, Riva G In our
protocol for the treatment of Generalized Anxiety Disorders we use
Virtual reality (VR) to facilitate emotional regulation and the
relaxation process. Using a biofeedback biomonitoring system (GSR, HR,
Thermal) the patient is made aware of his or her reactions through the
modification of some features of the VR environment in real time. Using
mental exercises the patient learns to control these physiological
parameters and using the feedback provided by the virtual environment is
able to gauge his or her success. To test this concept, we planned a
randomized controlled trial (NCT00602212), including three groups of 15
patients each (for a total of 45 patients): (1) the VR group, (2) the
non-VR group, and (3) the wai... | |

This
article provides tools for an analytic treatment of reward-modulated
STDP, which allows us to predict under which conditions reward-modulated
STDP will achieve a desired learning effect. These analytical results
imply that neurons can learn through reward-modulated STDP to classify
not only spatial but also temporal firing patterns of presynaptic
neurons. They also can learn to respond to specific presynaptic firing
patterns with particular spike patterns. Finally, the resulting learning
theory predicts that even difficult credit-assignment problems, where
it is very hard to tell which synaptic weights should be modified in
order to increase the global reward for the system, can be solved in a
self-organizing manner through reward-modulated STDP. This yields an
explanation for a funda... | |

Researchers
in the Department of Occupational Therapy and Occupational Science at
the University of Missouri are using neurofeedback to “retrain” autistic
children’s brains. Children play video games while sensors are attached
to their scalps; they are “rewarded” with movements on the screens and
special sounds for concentrating and focusing. From the April 23rd
Science Daily:
If attention wanes, the rocket on the screen slows, sounds stop and the
color changes until more attention is given to the image. As this
occurs, researches watch another screen that monitors brainwave
activity. The brainwave activity is measured by placing sensors on the
scalp.

Authors:
Cho MK, Jang HS, Jeong SH, Jang IS, Choi BJ, Lee MG The effects of
alpha-neurofeedback (ANF) on electroencephalographic alpha-activity were
investigated. Each session consisted of a 2.5-min eye-opened state and
17.5-min of ANF, which was divided into 16 1.25-min bins. Alpha
amplitudes were gradually increased as the session was repeated. The
maximum value at the start of ANF gradually decreased as time passed,
but the slowdown of alpha-activity during each session was decreased as
the session was repeated. The correlation between alpha-activity at the
end of ANF and at the following session's eye-opened state was highly
significant. These results showed that ANF enhances the ability of
alpha-activity to maintain itself rather than the increase of
alpha-amplitude during intrasessio... | |

I

can know when shifts in consciousness -- personal or societal -- are
happening. How can we know when we experience not just big dramatic
shifts in our ways of being, but even the little movements that might
take us from 3 out of 10 on some scale of change to 3.5 out of 10?
In working with people's brains using nonlinear methods of feedback, it
is very common indeed that people experience changes - shifts in their
ways of being, thinking, feeling, and/or acting - that they are just not
aware of at the time of the shift. Every neurofeedback practitioner I

CONCLUSIONS:
Subjects are able to control the BCI using only vibrotactile feedback
with an average accuracy of 56% and as high as 72%. These accuracies are
significantly higher than the 15% predicted by random chance if the
subject had no voluntary control of their Mu-rhythm. The results of this
study demonstrate that vibrotactile feedback is an effective
biofeedback modality to operate a BCI using motor imagery. In addition,
the study shows that placement of the vibrotactile stimulation on the
biceps ipsilateral or contralateral to the motor imagery introduces a
significant bias in the BCI accuracy. This bias is consistent with a
drop in performance generated by stimulation of the contralateral limb.
Users demonstrated the capability to overcome this bias with training.

therapy rewards scalp EEG frequencies that are associated with relaxed
attention, and suppresses frequencies associated with under- or
over-arousal. In large-scale clinical trials, the efficacy of EEG
biofeedback for AD/HD is comparable to that of stimulant medications.
Many different EEG biofeedback protocols for AD/HD are available.
Single-channel protocols developed by Lubar and interhemispheric
protocols developed by the Othmers are widely practiced and supported by
large-scale clinical studies. (Source: Positive Technology Journal) | |
![]() | Rogue Waves: The Ocean of the Brain |
I
came across a wonderful article that shows what happens in the ocean
when rogue "monster" waves appear and capsize ships.
What makes it wonderful and why am I writing about it here --- on a blog
about the brain and neurofeedback? You may not see a connection between
rogue waves on the ocean and what happens in the brain -- or why that
matters for our lives.
Good question. I hope by the end of my article you'll see why I was so
delighted to come across this story as a teaching tool about the brain
and how neurofeedback can work. (Source: Neurofeedback on the Brain) | |

I
came across this YouTube video called "The Simple Path" -- a lecture by
S.N. Goenka. It is part of series of broadcasts on Vipassana
meditation, also called mindfulness meditation -- "seeing things as they
really are".
What caught my attention in his talk was the notion of working at deep
levels in Vipassana meditation vs making surface changes in some other
meditative techniques.
It brought to mind the kinds of techniques people are often initially
fascinated by when they start exploring ways of training their brain for
better performance.
These techniques may include... (Source: Neurofeedback on the Brain) | |
![]() | The effects of neurofeedback training in the cognitive division of the anterior cingulate gyrus |
This
study examines the efficacy of neurofeedback training in the cognitive
division of the anterior cingulate gyrus and describes its relationship
with cortical regions known to be involved in executive functions. This
study was conducted with eight non-clinical students, four male and four
female, with a mean age of twenty-two. Learning occurred in the ACcd at
significant levels over sessions and in the anterior regions that
receive projections from the AC. There appears to be a multidimensional
executive circuit that increases in the same frequency in apparent
synchrony with the AC and it may be possible to train this sub-cortical
region using LNFB. (Source: Positive Technology Journal) | |
![]() | Are complex psychotherapies more effective than biofeedback, progressive muscle relaxation, or both |
Authors:
Stevens SE, Hynan MT, Allen M, Braun MM, McCart MR A meta-analysis of
26 studies was conducted to assess whether more complex forms of
psychotherapy would be superior to control treatments of either
biofeedback, progressive muscle relaxation, or both. Consistent with
hypotheses, more complex treatments provided a small, significant
improvement over biofeedback and progressive muscle relaxation (r =
.09). A subset of the more complex behavioral treatments accounted for
most of this small incremental effectiveness of more complex treatments
(r = .15). Possible sources of this incremental effectiveness are
discussed. (Source: Positive Technology Journal) | |
![]() | Brain potentials associated with outcome expectation and outcome evaluation |
This
study investigated whether feedback-related negativity can be elicited
by a randomly assigned cue indicating potential monetary loss. The
expected loss or win can be materialized or averted depending on
participants' performance in a subsequent game. Compared with the win
cue, the loss cue elicited a weak but significant feedback-related
negativity-like effect. It is suggested that the anterior cingulate
cortex, which generates feedback-related negativity, may function as a
pre-warning system that alerts the brain to get ready for future events.

neurofeedback: a brief overview and an example of peak alpha frequency
training for cognitive enhancement in the elderly. Clin Neuropsychol.
2007 Jan;21(1):110-29 Authors: Angelakis E, Stathopoulou S, Frymiare JL,
Green DL, Lubar JF, Kounios J Neurofeedback (NF) is an
electroencephalographic (EEG) biofeedback technique for training
individuals to alter their brain activity via operant conditioning.
Research has shown that NF helps reduce symptoms of several neurological
and psychiatric disorders, with ongoing research currently
investigating applications to other disorders and to the enhancement of
non-disordered cognition. The present article briefly reviews the
fundamentals and current status of NF therapy and research and
illustrates the basic approach with an interim report on a pi... | |
![]() | Neurofeedback for Children with ADHD |
This
study addresses previous methodological shortcomings while comparing a
neurofeedback-training of Theta-Beta frequencies and training of slow
cortical potentials (SCPs). The study aimed at answering (a) whether
patients were able to demonstrate learning of cortical self-regulation,
(b) if treatment leads to an improvement in cognition and behavior and
(c) if the two experimental groups differ in cognitive and behavioral
outcome variables. SCP participants were trained to produce positive and
negative SCP-shifts while the Theta/Beta participants were trained to
suppress Theta (4-8 Hz) while increasing Beta (12-20 Hz). Participants
were blind to group assignment. Assessment included potentially
confounding variables. Each group was comprised of 19 children with ADHD
(aged 8-13 years). Th... | |

Conclusions:
HRV biofeedback appears to be a useful adjunctive treatment for the
treatment of MDD, associated with large acute increases in HRV and some
chronic increases, suggesting increased cardiovagal activity. It is
possible that regular exercise of homeostatic reflexes helps depression
even when changes in baseline HRV are smaller. A randomized controlled
trial is warranted. (Source: Positive Technology Journal) | |

Well,
I'm impressed. Dr. Sarvenaz Zand, a physician wrote an article for ABC
News about "Treating Migraines Without Painkillers" -- and there are
biofeedback and neurofeedback -- front and centre!
How well does it work? According to Dr. Barry Schwartz, director of the
Headache Center in New Orleans, about 85 percent to 90 percent of
patients with chronic headaches respond positively to biofeedback.
"Biofeedback also serves as an excellent bridge in assisting patients
wean off medications," he said.
Of course, I do have a few thoughts about his presentation of

In previous articles, I've shared my distinction between neurofeedback training and "neurotherapy" treatment.

![]() | Menopause: It's in Your Head |
Not
all in your head of course.
But it's there....
Surging hormones...dysregulation (or at least a "re-setting" of the
system)...
And if you've experienced menopause and its hot flashes, you know you
feel like your brain isn't functioning on all cyclinders. (Many women
say the same thing about being pregnant, but that's a little different
story than this one.)
I find menopause fascinating from a neurofeedback perspective. Let me
share with you an "inside" view of the brain during hot flashes and
you'll see what I mean about menopause being firmly in your head!

I
haven't really talked on my blog about the emWave personal trainer
recently released by the HeartMath Institute.
It's handy little device that you can use to practice heart coherence
without having to have a computer on and that lets you wander as you
practice.
I have been using it with my clients and they have found it a useful
addition to training sessions. So much so, that several have asked to
purchase the extras I have for use in group classes.
So what's all the buzz about? I recently saw a great review of the
emWave personal heart coherence training tool on a The Gadgeteer.
This is wonderful review of the emWave with great pictures and a quick
video so you can see its use.

I totally understand why people want an answer to this question.
Unfortunately, I have to give that all-time number one frustrating
