• Asperger: Autistic psychopathy in childhood.
DIAGNOSTIC CRITERIA

o Abnormally restricted interests;
o Inflexible routines and rituals;
o Motor mannerisms;
o Preoccupation with parts of objects;
o Needs at least two of these.
1 in every 68 people meet the criteria for autism.
1 in every 100 people are autistic.
Huge increase from the 1970s, increase due to changes in the diagnostic criteria.
NON-DIAGNOSTIC FEATURES

Document Summary
What is autism: developmental disorder, affecting different aspects of cognition; Issues with social interaction, communication, disinterest and repetitive behaviour (not all together): affects people throughout their lifetime, kanner: autistic disturbance of affective contact, asperger: autistic psychopathy in childhood. Dsm-5 -> newly autism spectrum disorder a change to diagnostic criteria. Inflexible routines and rituals: motor mannerisms, preoccupation with parts of objects, needs at least two of these. 1 in every 68 people meet the criteria for autism. Huge increase from the 1970s, increase due to changes in the diagnostic criteria. Intellectual disability: memory problems, prosopagnosia, attention deficit, epilepsy, motor discoordination. Language impairment: reading difficulties, sensory hypersensitivity, dietary issues, savant skills, a heterogenous disorder. Theory for cognitive deficit in autism: people with autism have difficulties with theory of mind -> ability to understand behaviour, came from research in the 70s when finding that chimpanzees can recognise behaviour as a mental state.
