Yes, there are many societies dedicated to autism. One such society is the National autism Society in the UK, the organisation that first used the puzzle piece to represent autism.
Autism should be capitalized when referring to the disorder or condition itself, but not when used in a general sense (e.g., "children with autism" vs. "autism spectrum disorder").
Yes, a child can be diagnosed both with Autism Spectrum Disorder and a learning disability too. In fact Attention Deficit Hyperactivity Disorder is considered a 'cousin' to Autism Spectrum Disorder and is often comorbid with Autism.
Autism isn't a disease or a virus, thus there are no strains of autism. Autism is just autism, it was previously split up into Autism Spectrum Disorder (Classic Autism), Asperger Syndrome, Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), childhood disintegrative disorder, and Rett Syndrome - now all are merged under the Autism Spectrum Disorder diagnosis.
Autism is considered to be a disorder - thus why it's called Autism Spectrum Disorder. Autism is certainly not a personality, all Autistic people have vastly different personalities.
Obsessive-compulsive disorder (OCD) is not a symptom of autism spectrum disorders. However, people with autism spectrum disorders can exhibit behaviors that appear similar to OCD, without having OCD. Also, people with an autism spectrum disorder can have OCD as a comorbid condition.
Autism spectrum disorder and autism are both general terms for a group of complex disorders of brain development.
1 in 100 of the population have autistic spectrum disorder. 0.2% are female, and 1.8% are male.
I have not seen any studies on whether twins are more likely to have an autism spectrum disorder than single-birth children. It is possible that no one has done research on this. If one identical twin has an autism spectrum disorder, there is approximately a 90% chance that the other identical twin will. They might not have the same autism spectrum disorder or they might have the same disorder at different levels of severity. Many studies show the chance that they both have it if one twin does as somewhere between 82% and 97%. If the twins are fraternal (non-identical) twins and one has an autism spectrum disorder, the other has about the same chance of having an autism spectrum disorder as non-twin siblings do, which is greater than the chance of having an autism spectrum disorder in a family that does not have any history of it.
No. The descriptions of the autism spectrum disorders are such that you cannot have more than one. However, with more information, the diagnosis might change from one autism spectrum disorder to another. A person with an autism spectrum disorder can have other conditions or disorders, such as ADHD, epilepsy, or bipolar disorder.
Someone who is born on the autism spectrum/has autism spectrum disorder/is autistic. Often used in an offensive manner towards autistic people.
The scientific name for autism is autism spectrum disorder (ASD). It is a complex neurodevelopmental condition characterized by challenges with social skills, communication, and repetitive behaviors.
