What is autism spectrum disorder as a neurodevelopmental disorder?

Autism spectrum disorder as a neurodevelopmental disorder is a kind of this psychological disorder where children are not developing skills that are already part of their current developmental age right now.

Children with this kind of psychological disorder are also unable to form normal human relationships where they can have their own close peers.

Children with this kind of psychological disorder may have a lack of close attachment to their parents at their early years which is a common environmental factor that can develop this psychological disorder in children.

Of course, there is also the influence of genetic factors when developing this kind of psychological disorder. 


Researchers have noticed that children with this kind of psychological disorder are already having trouble when it comes to interacting with peers and loved ones even in the ages of 1 and 2.

Although this kind of psychological disorder is typically diagnosed when the child is at the age of 3 or 4.

This kind of situation has something to do about getting early intervention when the child is suspected to have this kind of psychological disorder.

Early intervention is what can help these affected children when they are in need of help for their psychological disorder and parents will make this happen.


There are also repetitive behaviours that can be exhibited when children are showing this kind of psychological disorder.

These kinds of behaviours are hand-flapping and rocking that may distress loved ones thinking that they have hurt them to engage in these behaviours.

Children with this kind of psychological disorder tend to not pay attention since they are more inclined to do these kinds of behaviours.

This is what distresses parents, especially if their child is going to school.

Children with this kind of psychological disorder have a hard time functioning in school, especially when they have the severe form of this psychological disorder.

The difficulty in school may be associated with having complications in social and academic areas.



Although this doesn’t mean that there is always a bad side to this kind of psychological disorder.

Some children with this kind of psychological disorder are great at math but they have a monotone voice which can debilitate their chances to have friends.

Some children with this kind of psychological disorder are great at memory but they are not great in some academic areas despite this kind of skill.

This is just a matter of determining which area needs to be improved in children with this kind of psychological disorder.

This is why behavioural interventions for this kind of psychological disorder are focused on what kinds of areas are in need of improvement in affected children.

This is where therapy is focused on and determine if it has been progressing at all or not which can induce a change in the intervention.

Explanation why autism is only genetic and not environmental

The largest study of autism being genetic including more than 2 million people across five countries, finds that these kinds of spectrum disorders are 80% dependent on inherited genes.

This kind of situation means that environmental influences on this kind of psychological disorder are only 20% risk.

The findings could open new doors to research into the genetic influences of this psychological disorder which the U.S. Centers for Disease Control and Prevention now states impacts 1 in every 59 U.S. children.

This kind of conclusion is trying to minimizing the weight felt by mothers who thought that this kind of psychological disorder was caused by a mother’s weight or other factors attributed to the mother. 

The new study found the role of maternal influences to be nonexistent or minimal due to this kind of conclusion


A team led by Sven Sandin who is an epidemiological researcher at the Karolinska Institute in Stockholm, Sweden stated that genetic influences are the predominant causes of this psychological disorder.

This new study has made the discussion of environmental causes of this psychological disorder to stop significantly.

A team of experts said in an editorial comment on the new study which was published July 17 in the journal JAMA Psychiatry stated that environmental influences that cause this kind of psychological disorder are much smaller than genetic factors that could cause this psychological disorder.

This kind of study may have arisen from the fact that genetic influences are typically ignored when it comes to studying this kind of psychological disorder.

There are other studies that have proven that genetic influences can trigger this kind of psychological disorder mostly.

According to Sandin and colleagues, the new study is the largest and most rigorous yet administered into the triggers of this psychological disorder. 

The researchers looked at the medical histories of more than 2 million children born in Denmark, Finland, Sweden, Israel and Western Australia between 1998 and 2012 in this kind of study.

All of these children were tracked until 16 years of age in this kind of study. 

Of the group of children, just over 22,000 went on to develop this kind of psychological disorder.

According to the data, about 80% of their risk of developing this kind of psychological disorder was caused by genetics with the remainder of the risk tied to as-yet-unidentified environmental influences. 

Only a negligible amount of risk, about 1%, was caused by maternal influences, the study researchers stated.

The researchers explained that the numbers were almost the same as those participants in smaller studies taking note of the genetic influences of this psychological disorder.

Dr. Andrew Adesman directs developmental and behavioural paediatrics at Cohen Children’s Medical Center in New Hyde Park, N.Y in regards to this kind of study.

Reviewing the findings, he agreed that it offers stronger evidence that this kind of psychological disorder is mostly due to genetic and not environmental influences.

Most families are more concerned about the environmental influences that they are placing their children with this kind of psychological disorder but researchers would like to remind them that genetic influences play a major role.

This kind of conclusion can make families ease up on their anxieties about being a better parent to their children.

Although this doesn’t mean that the researchers have found out the specific gene that causes this kind of psychological disorder.

There are still studies that will need to reassure this kind of part in this series of proving to people that genetic influences play a major role.

This kind of situation will only make parents think about their genetic whereabouts of having this kind of psychological disorder in their family tree.

This kind of procedure can help them prepare if their child has the possibility of having this kind of psychological disorder.

Inheritance pattern of autism spectrum disorder

As mentioned before, this kind of psychological disorder is inherited in families. This kind of situation would wake up the presence of an inheritance pattern.

However, this kind of pattern is not yet known by researchers. Some researchers have proposed that this kind of pattern can be explained when one genetic syndrome is associated with this kind of psychological disorder and it may have the tendency to connect with other syndromes in the affected person’s genetic material.

How did researchers know that autism is predominantly genetic?

Researchers know that autism is predominantly genetic by reviewing the early twin studies on this psychological disorder.

Both twins had this psychological disorder in the research study.

There were also environmental influences that are studied in this old study as well.

This twin study was able to tell them that there is the tendency for people with this psychological disorder to be influenced genetically and this can happen in their new family members as well if they choose to reproduce.

How do these genes trigger autism?

These genes trigger autism since they have some changes and gene variations that are present in affected people and people who are not affected.

These genes may have some mutations which can explain the psychological dysfunction in these affected people.

These genes can bring some gene mutations that can affect the brain. This is why these affected people have some changes in the brain as most researchers have observed.

These copy number variations are duplicated which can cause this psychological disorder.

Some of these variations when through other processes that are not found in people who don’t have this psychological disorder.

FAQs: is autism genetic

What is the genetic cause of autism?

The genetic cause of autism is an interaction of genetic predisposition and an early environmental insult.

There are several genetic factors that explain most of autism risk but not all of it are explained.

Several theories regarding environmental influences have been proposed to address the remaining risk.

Can you test for autism gene?

Yes, you can test for autism gene. When determining these kinds of genes in family studies, a large amount of candidate genes have been located where most of which encode proteins included in neural development and function.

However, for most of these candidate genes, the real mutations that boost the likelihood for this kind of psychological disorder have not been determined.

What percentage of autism is genetic?

The percentage of autism that is genetic is 90%. This kind of conclusion was based on early studies of twins that were estimated to have the heritability of this psychological disorder where the percentage of differences between those people with this kind of psychological disorder and people who don’t have this psychological are caused by genetic influences.

However, this kind of conclusion may be an overestimate since new twin data and models with structural genetic variation are needed in the study.

What is genius syndrome?

The genius syndrome or the savant syndrome is a kind of syndrome in which someone with significant mental abilities displays certain abilities far in extreme of the average.

The kinds of skills that these people who have this kind of syndrome are overall associated with memory.

These kinds of skills may involve fast calculation, map making, musical ability of artistic ability. 

How do you know if you have savant syndrome?

You will know if you have savant syndrome when you have significant mental abilities where you can display certain abilities that are far in extreme fo the average.

The skills that you may have may excel in relation to memory.

The kinds of skills you may have are fast calculation, map making, musical ability or artistic ability.
