This week is the World Autism Awareness Week. It's estimated about 1 in every 100 people in the UK is autistic. More boys and men are diagnosed with autism than girls and women. There is currently no effective medication to treat autism. Applied Behaviour Analysis (ABA) is often used in schools and clinics to help autistic children. In recent years stem cell therapy is applied to autism treatment, but its effect is still uncertain according to the latest report.
