Caudal 2007
Summary
Clinical trials were conducted at the office of Dr. Frederique Caudal, pediatrician
and specialist in Attention-Deficit/Hyperactivity Disorder (ADHD) in children.
Symptoms of this disorder are
related to a low level of cerebral neurotransmitters.
Variations in genes involved in the neurotransmitter
systems are likely to mediate this delicate balance and have an effect on the function of these chemicals in the brain.
The diagnosis of ADHD children is almost symptomatic, which leads to the dramatic possibility of error and treatment
(Ritalin®, or SSRI or catecholamine’s) with medications associated with numerous side effects in particular for
the age of the population.
For this reason, a new, measurable, and therefore objective marker was proposed
using the electro-medical system called the Electro Interstitial Scanner (EIS) in adjunct to the conventional diagnoses and
treatment monitoring of the ADHD children.
From 10.04.2006 to 05.16.2007, data from 59 children
(age 12 + 5) presenting symptoms and not undergoing treatment were recorded with the EIS System. This database was compared
with another control group database (age 14 + 6) of non-hyperactive children also recorded with the same EIS System.
Hypothesis tested
The hypothesis tested was:
Can the EIS System with reference to its ESG (Electro Scan Gram) graph be used
as a marker for ADHD children and therefore as adjunct to the conventional diagnosis of ADHD children?
This hypothesis was validated by statistical analysis.
It appeared,
following statistical analysis of the said database (STATISTICA), that the ADHD ESG graph generated by the EIS System presented
a specificity of 85% (CI calculated at 95%) and a sensitivity of 83% (CI calculated at 95%) when compared to a database of
non-hyperactive children.
The volume 9/10 of the ESG graph of the group diagnosed was 14.7 +/- 5 10-6 S.m-1
and the non-ADHD children was 4.7 +/-2.7 10-6 S.m-1 (P<0.0001, and P<0.0001 respectively)
The
volume 1/3/16/18 of the ESG graph of the group diagnosed was3.1 S.m-1+/- 0.6 and the non-ADHD children was 4.7 10-6 S.m-1+/-
0.7 (P<0.001, and P<0.001 respectively)
The volume 2/4/15/17 of the ESG
graph of the group diagnosed was 10.6 +/- 710-6 S.m-1 and the non-ADHD children was 28+/- 8 10-6 S.m-1 (P<0.0001, and P<0.0001
respectively)
In light of the results, the ESG graph generated by the EIS System may be considered
a marker for ADHD children and therefore as adjunct to the conventional diagnosis of ADHD children.
