Thanks to Bill, Tim, Jeff and Bruce for reponding to my post.
One of the things I will be doing after the initial selection of
children (which will by based on social agreement among parent, doctor,
teacher), is to give the children some special testing.
I will be giving the children a QEEG on and off the drug. This will
allow me to say how their brainwave properties (relative power,
coherence, phase, amplitude asymmetry) compare to a normative group on
and off the drug. If the QEEG off the drug does not show a large number
of out of range values, Bill's point would be supported. On the other
hand if the QEEG off the drug shows a large number of out of range
values, his point would be put into question. I will be able to find
out what percentage of children actual show abnormal QEEGs and what
percentage show normal QEEGs.
More accurately stated, for each property, say coherence, I will be
able to look at the distribution of the number of out of range values.
I expect that the ADHD cases will be bunched over on the higher side and
that the non-ADHD cases will be bunched on the lower side. This might
be true for all four properties, three properties, two properties, one
property or none of the properties. If none of the properties, this
would support Bill's statement that there is no neurological difference
between the two groups. If all four properties are different, this
would provide strong support for the idea that the there are
neurological differences between the two groups.
This research study is very traditional. It is designed to address the
question whether the diagnostic category does or does not reflect a real
physiological/brain difference. Seems like traditional research designs
may have a useful purpose after all. If the diagnostic category proves
real and not imaginative, the PCT question of how does a person with
ADHD control differently can be asked.
I suppose I should choose an equal number of children, say 10, in which
there is social agreement that they do not have ADHD. This would be a
I would expect a much larger percentage of abnormal QEEGs among the
identified children, 100% versus 0% would be nice. Something close to
this would support the idea that there is something different about the
brains of ADHD children even when they are just sitting in the chair
with eyes closed for about five minutes (the circumstances of the QEEG
Actually, studies like this have been done. Maybe not with the
particular software and norms I will be using.
