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.
A common question after an autism diagnosis is what is the cause of autism. We know that there's no one cause of autism. Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. These influences appear to increase the risk that a child will develop autism.
Genetics. Genetic factors may be the most significant cause of autism. Early studies of twins had estimated heritability to be over 90%, meaning that genetics explains over 90% of whether a child will develop autism.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
Level 1 is the mildest, or “highest functioning” form of autism, which includes those who would have previously been diagnosed with Asperger's syndrome. Individuals with ASD level 1 may have difficulty understanding social cues and may struggle to form and maintain personal relationships.
Can Level 1 Autism Be Cured? Autism of any level is a lifetime condition; there is currently no known cure. However, it is possible to help autistic individuals achieve a higher quality of life. Early diagnosis and clinical intervention are crucial for the best outcomes.
It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life. Autism is not a medical condition with treatments or a "cure".
Autism genetics expert Ivan Iossifov breaks down recent research that sheds light on how unaffected parents can pass autism onto their child. Parents with no history of autism in their families have a child who is diagnosed with the disorder. It's a common and upsetting story.
In the United States, prenatal genetic testing (PGT) for Autism Spectrum Disorders (ASD) is currently available via clinical genetic services. Such testing may inform parents about their unborn child's risk for ASD, prepare parents for the birth of an affected infant, and allow them to arrange for early interventions.
Sensory overload, changes in routine, social isolation, co-occurring conditions, and lack of support can all exacerbate the symptoms of autism. However, with early intervention, therapy, and support, individuals with autism can manage these challenges and improve their quality of life.
Long-term research that involved following a group of individuals with autism for two decades indicates that the average life expectancy for some autistic people is about 39 years. Furthermore, this population generally succumbed to health complications about 20 years earlier than individuals who do not have autism.
Risk Factors
Having a sibling with ASD. Having certain genetic or chromosomal conditions, such as fragile X syndrome or tuberous sclerosis. Experiencing complications at birth. Being born to older parents.
High levels of stress during pregnancy may also be connected to autism in children. This connection appears to have the most impact when the parent experiences stress between weeks 25 and 28 of pregnancy.
One of the most effective ways to treat level 1 autism is through utilizing the Theory of Mind. Theory of Mind and adaptive skills-based treatment that targets executive function, emotional regulation, cognitive flexibility, social communication skills, and anxiety reduction.
“Firstborn offspring of two older parents,” Durkin's study noted, “were three times more likely to develop autism than were third- or later-born offspring of mothers aged twenty to thirty-four and fathers aged under forty years.”
The chances of anyone in the general population having an autistic child are about 1 in 1000 or 0.1%. So, while the risk is real, the chances of you and your husband having an autistic child are still very low.
The behavioral symptoms of autism spectrum disorder (ASD) often appear early in development. Many children show symptoms of autism by 12 months to 18 months of age or earlier.
A recent study by Roberts et al. (2015) found a strong association between trauma, PTSD and autistic traits (which may have been sub-clinical) in adult women. This association was highest amongst those women with the most severe autistic traits.
Autism is a neurological developmental disability with an estimated prevalence of one to two percent of the American and worldwide population. The diversity of the disability means that each person's individual experience of autism and needs for supports and services can vary widely.
Autism characteristics can change significantly from ages 3 to 11.
Because autism spectrum disorder varies in severity with each child, there is no hard and fast rule. It is not uncommon for children with ASD to begin developing speech in the same manner as typical children, as well as to regress in speech and language comprehension around two years old.
If you still hear people use some of the older terms, you'll want to know what they mean: Asperger's syndrome. This is on the milder end of the autism spectrum. A person with Asperger's may be very intelligent and able to handle their daily life.
