In terms of diagnosis, differential diagnosis and treatment planning in neurological diseases, post-graduate education, as well as the education received during the medical and specialization process, is also very important. Accurate diagnosis and subsequent treatment planning of clinical conditions such as Multiple Sclerosis (MS), Neuromyelitis Optical Spectrum (NMO), and Acute Disseminated Encephalomyelitis (ADEM), which are autoimmune diseases of the central nervous system, are neurological diseases that may pose some difficulties in clinical practice. Anamnesis, examination, imaging and laboratory examinations contribute significantly to reaching the correct diagnosis in these diseases. While current developments in the diagnosis and treatment of these diseases can be followed through national and international symposiums and congresses, information sharing is provided on an online platform as much as possible due to the pandemic that has been ongoing for more than a year. Online MS academy digital book; It has been prepared to provide current information on the diagnosis, etiopathogenesis, differential diagnosis and treatment of MS, ADEM, NMO to neurologists and other healthcare professionals. A training module has been developed with courses consisting of specific periods, durations and contents. Each exchange rate is complementary to each other. We believe that this educational platform will make a significant contribution to post-graduation education and wish success to all participants.
