The authors of the paper study with artificial intelligence methods the mechanisms of mental and behavioral disorders in epilepsy (MBDE) remissions. Scientific researches has gone through the following stages. Description of MBDE research field. A book was developed [1] for description of the MBDE research field. RF MBDE operates with 27 MBDE diagnoses and a control diagnosis G40 (epilepsy without MBDE), 17 syndromes and 163 symptoms. Development of MBDE RF knowledge base. BC TPCE consists of 19 compartments and uses numerical and symbolic fuzzy values Knowledge base. Development of 19 metric spaces for evaluating distances between MBDE RF diagnostics. Development of 19 metric spaces for evaluating the similarities of MBDE RF diagnoses. An album of 76 MBDE distance and similarity evaluation tables was developed. The results of scientific research have been recognized with diplomas of excellence and gold medals at some international innovation and scientific research exhibitions and book fairs.
