Respected Dr.B.S .Rajpoot, Namaskar. First of all I will congratulate u for treating the autistic child of 15 years by transplanting the stem cell. It is a historic research in the disability field particularly in the case of autism. For the last so many years there was no treatment of autism. Stem cell transplantation will prove a sparking future in the life of disabled persons having a Mental Retardation, Autism, Cerebral palsy and Down syndrome problem etc. I am residing in small town of Shimla H.P. My son is having Autism and he is 23 years old. As u R aware that the Autism is a brain disorder that often makes it hard to communicate with and relate to others. With autism, the different areas of the brain fail to work together. Most people with autism will always have some trouble relating to speech. But early diagnosis and treatment have helped more and more people with autism to reach their full potential. But in my case my son has been diagnosed by 300 Doctors but with no improvement in his speech / memory/IQ level. He don t have allergy with any food. He can’t speak, some time he become an aggressive mood. He will have to support by the parents to his day to day routine work. Physically he is all right. In the light of above please suggest me can my son be treated by stem cell transplantation therapy? . Early response will be appreciated please. With warm regards. Sincerely yours C.L.TEGTA, MOBILE 0000 AND 0000.
