Autism Spectrum Disorder: Bioregenerative Medicine with Stem Cell Therapy is intended for a wide audience: parents of autistic children, regular and special education teachers, medical specialists, and for everybody who wants to learn about modern approaches to treat developmental diseases. This comprehensive monograph contains broad knowledge starting with a brief history of autism spectrum disorder, theories of occurrence and diagnosis, and reviewing modern behavioural, pharmacological, and bioregenerative therapeutic technologies. Why is this book different? It is grounded in recent data related to new conceptualizations of the occurrence of autism spectrum disorder which consider autism a mitochondrial disease. Thus, the authors explain core concepts. What is a mitochondrion? How does its damage appear and correlate to the signs and symptoms of autism? What kind of bioregenerative therapies have great therapeutic potential? Almost all therapeutic methods for autism spectrum disorder are discussed from the point of view of the evidence based medicine. Bioregenerative technology is based on the restoration of damaged subcellular structures like mitochondria and brain cell peptides. Bioregenerative antioxidant therapy, hyperbaric oxygen therapy, transcranial magnetic/direct current stimulation, and mitochondrial organelles replacement therapy are key directions in the treatment of autism spectrum disorder. Finally, new technology that holds high potential for the restoration of brain function is discussed-bioregenerative stem cell therapy. Because of the strong correlation between the symptoms of autism and changes in the brain, physicians have great tools to regulate such clinical symptoms through stem cell therapy. Most importantly, the authors have personal experience using the stem cell therapy with autism spectrum disorder patients. All facts are strongly supported by published scientific reviews and
