Autism spectrum disorder (ASD) is a neurological and developmental disorder that begins early in childhood and lasts throughout a person’s life. 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.
What kind of neurological disorder is autism?
Autism spectrum disorder (ASD), a common neurodevelopmental disorder, is characterized by deficiency in social communication and interaction and restricted, repetitive behaviors (Lai et al., 2014).
What category is autism spectrum disorder?
Autism Spectrum Disorder (ASD) refers to a group of neurodevelopmental disorders including autism, Asperger’s syndrome (AS) and pervasive developmental disorder-not otherwise specified (PDD-NOS).
Why is autism called spectrum disorder?
Autism is known as a “spectrum” disorder because there is wide variation in the type and severity of symptoms people experience. ASD occurs in all ethnic, racial, and economic groups. Although ASD can be a lifelong disorder, treatments and services can improve a person’s symptoms and ability to function.
What are the physical neurological symptoms of autism?
Neurological comorbidities are common in ASD and are associated with more severe phenotype, therefore warranting attention. Motor impairment includes both developmental delays and deficits, include stereotypies, dyspraxia, incoordination and gait impairments, and are often associated with cognitive impairment.
What are the 5 disorders on the autism spectrum?
There are five major types of autism which include Asperger’s syndrome, Rett syndrome, childhood disintegrative disorder, Kanner’s syndrome, and pervasive developmental disorder – not otherwise specified.
What are the 3 types of autism?

Which parent is responsible for autism?
Researchers have assumed that mothers are more likely to pass on autism-promoting gene variants. That’s because the rate of autism in women is much lower than that in men, and it is thought that women can carry the same genetic risk factors without having any signs of autism.
What is the most common known genetic cause of autism spectrum disorder?
Have you heard of fragile X syndrome? If not, you’re not the only one. Most people would be surprised to learn that it’s the most common identified cause of inherited intellectual disability. Fragile X syndrome is also the most common known cause of autism or autism spectrum disorders.
