In a 1999 study, Thomas Budzynski, Ph.D worked with 8 struggling college students. After undergoing audio-visual brainwave stimulation, the students outperformed a control group and significantly increased their GPA. GPA for the 8 students continued to rise even after treatment was discontinued!
Psychologist Michael Joyce used brainwave entrainment with a group of 30 children. He observed improvements in reading and a half year advancement in grade level as well as substantial improvements in attention, reaction and a reduction in impulsivity and variability.
Harold Russel Ph.D. and John Carter, Ph.D., of the University of Houston, did several studies in which they used brainwave entrainment to treat ADHD and other learning disorders, testing their IQ before and after treatment. Astonishingly, after treatment the subjects showed a 5 to 7 point increases in IQ score.
Michael Tansey used a similar protocol to treat dyslexia and other learning disorders, reporting a 19 point average increase in IQ score post-treatment.
Drs. Siegfried and Susan Othmer found that neurofeedback brainwave training in the 15-18 Hz range also can produce significant shifts in IQ score, particularly with people who are suffering from ADD/ADHD and other disorders. In cases where the starting IQ value is less than 100, the average IQ increase was 33 points! They also found significant improvements in memory, reading and arithmetic. In a one year follow-up, trainees showed major improvements in self-esteem, concentration and self-expression.
