Autism Spectrum Disorder (ASD) for a child results in representing altered communication, different ways of interacting, and strange experiences of the surrounding environment. More and more parents in the UK are applying for autism assessments for their children with the greater public awareness and improved services to assist. Whether you are just going on the path or preparing for a future appointment, knowledge about how the process works will reduce concern and enable you to feel more assured. This article discusses some of the most common parental queries concerning assessments for autism, offers preparation advice, and goes into the science behind autism.

What questions do parents get asked in an autism assessment?

In the UK, the parents are at the centre of an autism assessment. The professionals rely on your observations and experiences and any insights you can offer about your child in terms of development. Some typical questions that you may be asked include:

  • Developmental milestones: When did your child walk, talk, or achieve toilet training?

  • Communication: How does your child express himself or herself-will he/she talk, use gestures, or use facial expressions?

  • Socialisation: How does your child interact with family and peers or strangers?

  • Behaviour: Are there any repetitive behaviours, obsessive interests, or strange reactions to any changes?

  • Sensory sensitivity: Does your child react strongly to any weird sounds, textures, lights, or smells?

  • Daily life: How does your child manage routine, school, and social activities? 

It is important to stress that these questions are not framed to make you pass or fail, but instead, they will enable a complete picture of your child's needs according to which the professionals will suggest the best diagnosis and assistance possible.

How to prepare for an autism assessment in the UK?

Make sure to be all prepped before attending assessment because it smoothens the process both for your child as well as you. Here are some of those practical steps:

  • Information about Developmental History: Write developmental history including major milestones, behaviours, or any teacher's and doctor's observation or concerns.

  • Gather reports: School feedback, health visitor notes, or any speech and language therapy report. As if these are available, include it.

  • Document any Comorbidity: Record instances of repetition, deprivation of senses and social isolation.

  • Talk to your Child (if age appropriate): Depending on their age and understanding: Tell that they are going to meet someone who would like to know more about how they learn and play.

  • Prepare your Questions for Professionals: Do not forget to ask anything regarding supporting the possible options, time-waiting and any local resources that might become available after the assessment.

An organized scheme makes professionals deliberate and accurate decisions and assures you that nothing is missed.

What do parents need to know about autism?

Parents often consider some important things while wondering about what it has been diagnosed. The following are some important points to keep in mind. 

  • Autism is a lifelong condition: Children do not "grow out" of it but, with appropriate support, can do very well.

  • Every child is different: Autism means that no two children are alike; they all present differently.

  • Strengths co-exist with challenges: Most autistic children show incredible focus, creativity, and memory skills while also showing "challenges."

  • Help is out there: Be it from school adjustments under the SEND (Special Educational Needs and Disabilities) framework to local autism support groups, help is available across the UK.

  • Diagnosis: Diagnosis is a gateway, not a label to important added resources: targeted educational strategies and therapeutic support but also better understanding within the family and school.

What is 90% of autism caused by?

Research indicates that the primary causes for autism are genetics, and inherited genes are responsible for the origin of 80 to 90% of autistic traits, leaving behind the environmental factors. However, in developing the autistic condition, there is not a single gene responsible but rather a basketful of genetic variations. 

Some environmental insults-the likes of which may happen during the pregnancy-probably-but less in comparison to genetics. Among the examples of such environmental factors, pregnancy complications, low birth weight, and premature birth are noteworthy. However, vaccines, parenting style, and diet cause autism-last theory should be forever buried in the myths.

Which parent carries the autism gene?

Autism is by no means a condition transmissible only through one parent exclusively but rather a multi-factor and complex interplay of both parents' genetic factors influencing the predisposition to autism. Such genes are being transferred possibly from either or both of the parents to affect predisposition to autism. 

Family history of autism is indeed a crucial factor in the incidence of autism, but it does not guarantee one. At times, one of several children will have an autistic child born to otherwise several children born to parents, one or more of whom do not have autism. Therefore, no one is to blame here: not the parents and not the individuals concerned.

What is the refrigerator mother theory?

Mid-20th century has given rise to the much-hyped concept known as the "refrigerator mother" theory, which stated that autism was a result of cold, unloving mothers. Implicit in this theory was the proposition that such mothers do not bond with their children.

This theory is very much dead in the waters of research today. Today's science knows autism to refer to a neurodevelopment disorder that has its origins primarily in genetics rather than parenting style. It has a regrettable legacy in terms of guilt for probably millions of families. The focus today is to support these children and families with understanding and compassion, rather than blame.

Conclusion

The process of obtaining an autism assessment in UK can seem very daunting at first, but parents can gradually and confidently approach the process through preparation and knowledge. Remembering that autism is not a bad parenting issue, and no one is to blame-the person is a child with an atypical neurodevelopmental profile. With the diagnosis, the family gets enrolled in an important paradigm of support to aid their child in reaching his full potential at home, at school, and in society.
