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.
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.
In most cases, autistic people receive a diagnosis in childhood, usually after the age of 4 years. However, some autistic adults are not diagnosed in childhood, even if their symptoms are more severe.
Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father. One of the most common questions asked by parents of children with autism is which parent carries the autism gene.
Having a family health history of ASD makes you more likely to have a child with ASD, or to have ASD yourself. If you have a child with ASD, you are more likely to have another child with ASD, especially if you have a daughter with ASD or more than one child with ASD.
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.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
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.
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.
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.
Autism is likely to have multiple genes responsible rather than a single gene. However, it is not caused by emotional deprivation or the way a person has been brought up.
It showed that men in their 30s are 1.6 times as likely to have a child with autism as men under 30; men in their 40s have a sixfold increase.
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.
It is possible to be mildly autistic, but many of the behaviors and preferences found in people with autism are also common to people who do not have autism. The difference is that people with autism engage in these behaviors in different ways and for different reasons.
Although 2019 research suggests some symptoms of ADHD and ASD overlap, there are distinct differences. A person with ADHD may have attention, hyperactivity, and impulsivity challenges. But an autistic individual may have difficulties with communication, social interaction, and restricted or repetitive behaviors.
A good place to start might be to do a self-assessment. There is a questionnaire called the AQ10 test which you can download and complete to give a general indication of whether someone might have Autism. There are 2 versions available, one for adults & one for children (AQ10 for children).
Although both OCD and ASD have similar symptoms, they are different conditions. OCD is a mental health disorder, whereas ASD is a developmental condition. ASD is a condition that a person is born with. OCD can develop during a person's lifetime.
Autistic people can often have trouble sleeping. There are a range of reasons for this including difficulties with relaxing or winding down and irregular melatonin levels. Problems with sleep can be an issue for both autistic adults and children.
Boys are four times more likely to be diagnosed with autism than girls. Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.
