Discovery
In the 1940s, two researchers were studying autism in different countries; Hans Asperger in Austria and Leo Kanner in the United States. In 1943 Kanner (a doctor from Johns Hopkins University) did a study of 11 children. He found out that they had difficulties such as changing environments, being sensitive to certain stimuli, having speech problems, and allergies to food. Later he named the children’s condition “early infantile autism”, now called autismspectrum disorder. Hans Asperger was do...
Later history
Schizophrenia and autism were linked in many researchers’ studies. It was in the 1960s when medical professionals started to see these two disorders as separate conditions.

Since then, early infantile autism is called autism disorder. For the first time the DSM also introduced standardized criteria to diagnos...

Diagnosing autism can be hard because there is no medical test like a blood test. Instead, an evaluation is made by a team of doctors and other health professionals who are experienced in autism and know the person trying to get diagnosed.
