This study is intended 1. To quantify the effects of the iRemember personalized EEG-NFB therapy on working memory and executive functions in subjects with MCI by calculating the percentage of change in the Neurotrax tests performed prior to and after the treatment, and compare the results between the active treatment and placebo cohorts

By using the BestBrain iRemember EEG-NFB System, subjects within the "treatment" arm of this clinical investigation will show improvement in working memory, executive functions and general improvement in daily life based on standard accepted cognitive tests such as the Neurotrax and Kielhfner questionnaire. This hypothesis will be accepted or rejected based on the statistical analysis of the data collected .

Subjects will be randomized either to the treatment or placebo groups. Each subject will undergo an initial and final assessment using NeuroTrax and specified questionnaires prior to and after 20 treatments. The first sessions will be dedicated to subject evaluation. Each subject will undergo either a neurofeedback (NFB) or sham treatment.

5. Agreement to participate in approximately 12 weeks during the study.
6. Normal to near-normal vision and hearing with correction as needed (e.g. corrective lenses, hearing aid).
