GSR EDA electrodermal screening meters

The following are some interesting links to EDA meters I have found. There is even a make it youself blue print in public domail .

There is also the Thought Stream- a system with a sensitive GSR that I used with ADHD screening and biofeedback.

New studies show EDA activity in ADHD is valid marker

It has been since 1991 that I have found that the GSR galvanic skin response and EDA electro dermal activity were valid and important modalities in helping ADHD. It has been lonely having this view because it was overshadowed by EEG neurofeedback. However, recently more and more articles and research is coming out showing that the EDA has allot to teach us about ADHD. It actually might be a major key in our understanding of ADHD. So I feel vindicated now and am happy to point out these studies in this Blog.

A few studies have been coming out supporting the role of electro dermal activity as a measure and screening in ADHD. In the following study EDA and EEG was used to suggest that different psychophysiological processes may underlie ADHD in each sex.

More data proposing GSR as a screening in ADHD

In my search of additional research to corroborate my proposal that electical dermal activity might be used as an objective physiological screening test in ADHD I just came across the following research paper.
"Event-related brain potentials, bilateral electrodermal activity and
Mangina-Test performance in learning disabled/ADHD pre-adolescents
with severe behavioral disorders as compared to age-matched normal
controls"

Montreal Research and Treatment Center and Department of
Neuro-Psychophysiology, Division of Child and Adolescent Psychiatry,
Douglas Hospital, McGill University, Montreal, Quebec, Canada H3A 2B1


Briefly their study and I quote found that "Furthermore, significant differences between normal and
pathological groups were found in bilateral electrodermal activity
(F1,18=23.86, P<0.001) and on the Mangina-Test performance
(F1,18=75.35, P<0.001). " and "Our present research findings provide an
original and valuable demonstration of an integrative and effective
clinical psychophysiological application of central (ERPs), autonomic
(bilateral electrodermal activity) and neuro-psychometric aspects
(Mangina-Test) which characterize normal and pathological
pre-adolescents and underpin the neurophysiological basis of learning
disabled/ADHD with severe behavioral disorders as opposed to normal
subjects."

Electrodermal Activity Different in ADHD ( GSR)

Since the early 1990's I have been an advocate of using electrodermal activity as an simple objective physiological screening test in ADHD. Althogh I had been using GSR biofeedback for helping ADHD children and students increase focus as well as learn to achieve relaxed concentration in the classroom, there had been more of a focus on EEG biofeedback and neurofeedback for helping ADHD. These methods still remain controversial and expensive as well as time consuming to achieve results. In 2006 , I had released an educational video showing how the GSR could be used to screen for attention difficulties in ADHD - GSR Biofeedback Techniques For The Natural ADHD Practitioner. This data was compiled over a 15 year period helping ADHD students in Israel. Only recently , I have been able to find brain research studies showing a link between ADHD and abnormal or different electro dermal activity in ADHD. The following are links to studies now corroborating a link between electrodermal activity in ADHD, and subsequently support GSR biofeedback as a valid and primary modality in managing ADHD.

Method for determining attention deficit hyperactivity disorder (ADHD) medication dosage and for monitoring the effects of (ADHD) medication Document Type and Number:United States Patent 6520921 Link to this page:http://www.freepatentsonline.com/6520921.html Abstract:A method for determining the appropriate dosage of a medication to treat Attention Deficit Hyperactivity Disorder (ADHD) in an individual who has ADHD comprising: sampling the peripheral skin temperature of a human subject during a predetermined time interval when the subject is in an inactive state to provide sampled peripheral skin temperature data; analyzing the sampled peripheral skin temperature data for a pre-selected parameter to determine whether the pre-selected parameter has a value indicative of ADHD; and determining the proper dosage of a medication to treat ADHD based upon the determined value of the pre-selected parameter.
