Primary and secondary autism
Environmental factors that are associated with autism spectrum disorders and not only Asperger syndrome include mother having a viral or bacterial infection during pregnancy, mother smoking during pregnancy, exposure to air pollution and pesticides and the advanced age of the father.
The cause of Asperger syndrome, like most ASDs, is not fully understood, but there is a strong genetic basis, which means it does tend to run in families. Multiple environmental factors are also thought to play an important role in the development of all ASDs.
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.
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.
There are many different factors that have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
Advances in diagnostic capabilities and greater understanding and awareness of autism spectrum disorder seem to be largely driving the increase, the Rutgers researchers said. But there's probably more to the story: Genetic factors, and perhaps some environmental ones, too, might also be contributing to the trend.
The life expectancy for Level 2 ASD ranges from 50-60 years old. This is slightly lower than Level 1 and the national average. In some studies, the life expectancy is even lower.
When autism (or Aspergers) runs in families it is clear that they are at least partially inherited from the parents and/or the extended family. The parents or other family members may not necessarily have a diagnosis, but are carriers of genetic anomalies which in combination may cause autism in their offspring.
Autism Corner: Personality Types in Asperger's: Fixated, Disruptive, Approach and Avoidant. Fixated Personality–The fixated personality type can be characterized by a preoccupation with orderliness, perfectionism, and the need to control one's environment (e.g., to have things in a particular order).
A significant number of people with Asperger's Syndrome have been perceived to display either an over-sensitivity or an under-sensitivity to sensory stimuli. This includes all, or a combination of: touch, taste, smell, sound, sight and movement, as well as possible problems with motor co-ordination.
Although the involvement of genetic abnormalities in autism spectrum disorders (ASD) is well-accepted, recent studies point to an equal contribution by environmental factors, particularly environmental toxicants. However, these toxicant-related studies in ASD have not been systematically reviewed to date.
Many autistic people experience hypersensitivity to bright lights or certain light wavelengths (e.g., LED or fluorescent lights). Certain sounds, smells, textures and tastes can also be overwhelming. This can result in sensory avoidance – trying to get away from stimuli that most people can easily tune out.
1 in 100 children are diagnosed with autism spectrum disorder as of 2021. Autism prevalence has increased 178% since 2000. The country with the highest rate of diagnosed autism in the world is Qatar, and the country with the lowest rate is France.
“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 reason behind the reclassification of Asperger's syndrome was its similarity to autism, and the fact that it was distinguished from the latter based simply on a lack of language and cognitive delay — which, interestingly, isn't something every individual on the spectrum experiences.
Signs and symptoms of Asperger's syndrome
People with mild autism tend to have difficulty with social interactions. This can show itself as difficulty understanding others' feelings, expressing your own feelings, understanding gestures, and making eye contact.
Kids with Aspergers begin to talk at the expected age, saying their first words around 12 months of age. However, their actual first words are often unusual (e.g., such first words as palm pilot, sheetrock, clock, mountain, fish, hammer). These words are generally used before the youngster says “mommy” or “daddy.”
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.
A healthy diet for people with autism means eating foods like grass-fed meat, pasture-raised eggs, organs, and fresh fruit. Make sure to avoid any processed foods with added sugar and vegetable/seed oils completely if you want to thrive. Avoid drinking anything with caffeine or added sugars or artificial sweeteners.
