Cognitive Enhancement with LORETA Z-score Neurofeedback.

Our group has previously reported evidence of successful cognitive enhancement (Koberda,Moses, Koberda, Koberda, 2012 and Koberda, 2012) with Low Resolution Electromagnetic Tomography Analysis (LORETA) Z-score Neurofeedback (NFB). One case report included an individual with Asperger’s Syndrome (Koberda, 2012) associated with speech expressive dysfunction; another one described a student with low information processing speed and decreased memory (Koberda, Moses, Koberda, Koberda, 2012). This presentation contains a larger case series report where 21 consecutive patients complaining of cognitive dysfunction were subjected to LORETA Z-score NFB therapy. Before NFB initiation these patients were evaluated with computerized cognitive testing in order to document and confirm any cognitive dysfunction reported in chief complaint. Many patients underwent brain imaging and laboratory testing to rule out any treatable condition which could have contributed to the patient’s symptoms. Electrical imaging with QEEG/LORETA localization was also completed in order to visualize any area of cortical dysregulation which could have been potentially responsible for the patient’s symptoms. The NFB protocol was based either on the patient’s symptoms, the areaof cortical dysregulation, or both. After 10 sessions of surface/LORETA Z-score NFB the computerized cognitive testing and QEEG were repeated in order to see if any increase in cognitive score and/or reduction in QEEG abnormalities were achieved. In addition, the subjective patient’s response was recorded as to whether or not they felt that the therapy was beneficial. Thirteen (13)patients (62%) were found to have evidence of cognitive improvement based on the results of repeated cognitive testing. Out of these 13 patients ten (10)patients were identified to have also an improvement in QEEG abnormalities.Subjective improvements were also noted in 71% of patients after NFB completion. These results are very promising and indicate high potential effectiveness of LORETA Z-score NFB in cognitive enhancement.
