Dear Physician, Psychiatrist, Psychologist, and Mental Health Professional:

Increasingly, patients and families of patients with neuropsychiatric symptoms want
 the assurance provided by evidence-based evaluations.  My goal is to be your resource
in helping you provide as complete assessment as possible.  Lexicor, the provider of the
QEEG and the NeuroLex report service, provides me access to psychiatric experts
who evaluate EEG data.  I have the time, tools and ability using clinical practice guidelines
to provide you and your patients the confidence and peace of mind that comes with the most
comprehensive, evidence-based, patient-centered evaluations.

The service I provide includes the processing, analysis and reporting of clinical data
 to you and facilitates the mathematical and statistical transformation of EEG data for use
in clinical practice.  Each NeuroLex report is reviewed by a board-certified neurologist who
provides an over-read of the data and prepares a written evidence-based clinical report,
 which will integrate into the comprehensive evaluation of your patients. The QEEG
component is deemed by researchers to be the most accurate tool in a comprehensive
process which may also include psychiatric interviews and psychological testing.

The published literature on QEEG technology is extensive. 
Researchers who have confirmed the efficacy and validity of QEEG analysis include:

- The American Neuropsychiatric Association;
-  Brain Research Laboratories, NYU School of Medicine
-  Department of Psychiatry, Mercer University, Georgia
-  Journal of Child and Adolescent Psychiatric Clinics;
-  Journal of Clinical Neurophysiology;
-  Journal of Neurotherapy.

Research has noted that QEEG is 90% accurate in determining the likelihood of ADHD and ADD. 
And, QEEG is 95% accurate in determining the likelihood that ADHD and ADD does not exist
and that other disorders, such a those of mood or sleep, may better account for
observed neuropsychiatric behaviors.  Research also indicates that the qEEG process
 can identify brainwave patterns specific to those individuals exhibiting signs of
Asberger's Syndrome and Autism. 
 Determining if ADHD or ADD in fact does not seem likely, or that other problems
may be more potent, is very important as it has tremendous implications for education,
 treatment and medication.  Please note that data from the qEEG process and analysis
 is but one component of a comprehensive assessment of an individual.

Technical Information on ADHD/ADD and Brainwaves

ADHD and ADD may have many causes, such as exposure to alcohol, drugs and toxins during a
child's prenatal and fetal stage, altered brain function and anatomy and early exposure to
toxins after birth.  Later in a child's life the brain begins to become dysfunctional in
various ways.  Brainwave electrical activity becomes different in those children.

Research has proven a definite link between brainwave patterns and ADHD/ADD.
In those with ADHD/ADD, brainwaves known as theta waves  (associated with drowsiness, 
sleep and daydreaming) "over-ride" or interfere with beta waves (associated with
concentration and focus), thus causing various visual, auditory, memory,  emotional
 and cognitive problems. 

Below is a graphic which shows electrical activity levels in the various parts of the
brain as measured by EEG electrodes. Brighter colors (red, gold, orange, yellow) indicate
 stronger electrical activity and darker colors (greens, blues) indicate weaker electrical activity.
By knowing which areas exhibit strong or weak electrical activity, we are able to more
accurately determine the specific deficits that are likely to be present.

 QEEG detects electrical activity across the prefrontal, frontal, parietal, temporal,
 occipital, and midline areas. Using the International 10-20 System of electrode placement,
electrodes are placed at  F1, F2, F3, F4, F7, F8, FZ, T3, T4, T5, T6, C3, CZ, C4, P3, PZ, P4, 01, 02. 
Six electrodes are placed around the eyes and two are placed on the ears to adjust
the readings for any artifact signals.
