It affects how a person acts and interacts with others, communicates, and learns. It includes what used to be known as Asperger syndrome and pervasive developmental disorders.
How does the autism spectrum work?
Autism spectrum disorder (ASD) is a developmental disability caused by differences in the brain. Some people with ASD have a known difference, such as a genetic condition. Other causes are not yet known. Scientists believe there are multiple causes of ASD that act together to change the most common ways people develop.

Why is autism more common in boys?
Since autism is a largely genetic and hereditary condition, genetic factors that lead to differences depending on sex come into play, such as the role of androgen signalling in male development or X-linked mutations, whose associated genetic conditions are typically more common and severe in males.
Does autism come from the mother or father?
The team found that mothers passed only half of their structural variants on to their autistic children—a frequency that would be expected by chance alone—suggesting that variants inherited from mothers were not associated with autism. But surprisingly, fathers did pass on substantially more than 50% of their variants.
What does being on the spectrum mean?
“On the spectrum” usually refers to the specific set of behavioral and developmental problems and the challenges associated with autism spectrum disorder. A diagnosis of ASD means that your child's communication, social, and play skills are affected in some way.

Autistic people have decreased amounts of brain tissue in parts of the cerebellum, the brain structure at the base of the skull, according to a meta-analysis of 17 imaging studies5.
What neurological impairments are typically Characterised in autism?
Neurological comorbidities in autism spectrum disorders (ASD) are not only common, but they are also associated with more clinical severity. This review highlights the most recent literature on three of autism's most prevalent neurological comorbidities: motor impairment, sleep disorders, and epilepsy.
What is the most prevalent neurological disorder associated with autism?
In our cohort, ID and epilepsy were the two comorbid disorders most common with autism. A previous study reported that 70% of patients with autism had ID (Tuchman and Rapin, 2002), while the prevalence of autism with comorbid epilepsy has been estimated at 8–30% (Tuchman and Cuccaro, 2011).
Can you be on the spectrum and not have autism?
No two people with autism spectrum disorder (ASD) have the exact same set of symptoms. ASD is referred to as a spectrum because of the variety of its signs and symptoms, and their differences in severity. Some people with ASD experience symptoms that make daily life difficult.
