American Psychiatric Association Annual Meeting, Course: Intro to Neurofeedback, San Francisco May 19, 2003

ABSTRACT


Course Title: Using Neurofeedback in Your Practice:
Latest Trends and Hands-On Experience


IX. Educational Learning Objectives: At the conclusion of this course, the participant should be able to recognize indications for EEG biofeedback (neurofeedback), be familiar with the practical use of Quantitative EEG studies, understand how neurofeedback procedures are performed, and evaluate clinical neurofeedback research.

X. Course Description

After a brief introductory review on the history of EEG biofeedback (neurofeedback) and its current applications in psychiatry, the course will launch into an extended demonstration with hands-on experience for participants.

A demonstration of a Quantitative EEG (QEEG) will be performed on a volunteer. After the recording is analyzed, the database comparison will be used to develop an individualized neurofeedback protocol. A short technical lecture on the QEEG will follow. Next, all participants will have an opportunity to experience neurofeedback. Several neurofeedback systems will be used in the demonstration, including an experimental biofeedback-videogame interface. A short technical lecture on neurofeedback will follow

The final segment will present the latest data from a rigorously designed study of Attention Deficit-Hyperactivity Disorder (ADHD) children which compared “traditional” neurofeedback videogames to a new type of Sony PlayStation interface. In a preliminary study, both the videogame and standard neurofeedback improved the attention skills functioning of children with ADHD above the benefits of medication. The videogame technology provided advantages over standard neurofeedback treatment in terms of enjoyability for the children and positive parent perception, and possibly has stronger quantitative post-treatment effects on the QEEG.

High Level Of Success (80-90%)
Permanent Effects
Can Replace/Reduce Medication Requirement

QEEG: The Concepts

Brain Functioning Is Localized
Abnormal Brain Function Produces Abnormal Behavior, Experience, Mood
Normal Brain Function Produces Normal EEG Profiles
Abnormal Function Produces Abnormal EEG Profiles Which Relate To Symptoms
Localized Abnormalities Of Brain Function Produce Specific Symptoms
Create Large “Reference” Databases Of EEG Profiles Of Normal People
Collect EEG Data Under Standardized Conditions (Resting Or Tasked / Eyes Open/Closed)
Select Artifact-Free Data From Collected Data
“Discriminants” - Compiled EEG Databases From Known Patient Populations

EEG Measures

“Absolute Power”
“Relative Power”
“Asymmetry”
“Coherence”
“Synchrony”- Back/Front Coherence
“Multivariate” Measures
“Connectivity”
Brain Areas Must Be Able To Talk To Each Other
Otherwise “Cutoff”
Cutoffs In Stroke, Learning Disabilities, Add, Head Injury
Connectivity Is Measured By “Coherence” And “Comodulation”
Coherence = (Square Of) Correlation Between EEGs Outputs At Separated Sites
Comodulation = Correlation

ADHD And QEEG

Deficit In Frontal Delta - Nearly Universal
Beta Deficit - 2nd Marker For Cerebral Underactivity
Frontal Alpha Excess - Add With Depression / Anxiety
Frontal Theta Excess - Classic “Hyperactive” Profile
“T6” Alpha Excess - Rage Disorders
“Midline Enhancement” - Over-Focused Type
“Mu” As ADD Indicator
“Mu” - Originally Thought To Be Normal Variant
Now Known To Be ADD Marker

IV. New Biofeedback Interfaces for ADHD Children (deBeus)

Objectives

• This project was a randomized and controlled technology concept study, funded by NASA’s Langley Research Center

• Assessed whether a new videogame biofeedback technology developed at NASA Langley Research Center was as effective as traditional neurofeedback in treating Attention-Deficit Hyperactivity Disorder (ADHD), and whether there were significant differences in its appeal as a clinical method compared to standard neurofeedback treatment

• The study was conducted in the Behavioral Medicine Clinic at Eastern Virginia Medical School

Subjects

• 22 children with ADHD of the hyperactive-impulsive subtype (DSM-IV criteria plus physician diagnosis)

• Age range: 9-13 years, 3 girls and 19 boys

• All the children were on short-acting medications for ADHD

• The children had to be of at least normal intelligence, and have no history of affective problems or learning disabilities

Design

• The children were randomized to treatment groups: videogame (n=11) vs. standard neurofeedback (n=11)

• Children in both groups completed 40 individual treatment sessions, usually seen once or twice a week.

• The children came for one test session before and after treatment, where they completed QEEG, TOVA and neuropsychological tests.

• BASC Monitor data and actigraph (physical activity) data was collected pre-and post-treatment and every ten sessions

• Children in both groups were trained with a single active Cz electrode, with reference electrode and ground attached to the earlobes

Summary of Findings

• Both the videogame and standard neurofeedback groups improved significantly on most main ADHD outcome measures. No significant difference in treatment change was seen in group comparisons

• Parents’ subjective appraisal of treatment effect on ADHD was more positive for the videogame group

• The videogame treatment was rated significantly more enjoyable by both parents and children

• Trends on pre-post QEEG change maps indicate that the videogame training may have advantages in creating more quantitative EEG effect in the therapeutic direction
Conclusions

• We conclude that the videogame biofeedback technology, as implemented in the NASA prototype tested, produces equivalent results to standard neurofeedback in effects on ADHD problems

• Both the videogame and standard neurofeedback improve the functioning of children with ADHD substantially above the benefits of medication

• The videogame technology provides advantages over standard neurofeedback treatment in terms of enjoyability for the children and positive parent perception, and possibly has stronger quantitative post-treatment effects on EEG
