Improvement extended above and beyond the normal range for many individuals. As can be seen, only a handful of subjects demonstrated marginal declines in impulsivity scores while the majority improved greatly and in proportion to pre-treatment values. Response variability improved 25.9 points and inattention scores improved by 40.4 points for those with pre-training scores of 70 or below. Only adults with pre-treatment scores of 105 or below were included. The data are sorted by pre-training score.
Improvement is indicated when the line segment rises above the pre-training value.
The present study demonstrated the efficacy of neurofeedback in treating attentional deficits in adults using an outcome study. Significant improvement was found for inattention, impulsivity, and variability of response after 20 or more sessions of neurofeedback. The effectiveness of neurofeedback is all the more impressive given the fact that many of these subjects were difficult patients who had already undergone numerous prior treatments including stimulant medication with little or no success and a variety of settings and clinicians were involved in this study. Some of the adults had suffered from attentional and cognitive disorders for 20 to 30 years. All of these obstacles were overcome, indicating the robustness of this intervention.
