What is ASD?

Autism Spectrum Disorder is a developmental disorder. It is characterized by difficulty in communication. In addition to that, challenges in behavioral & social aspects. Impairment in social interaction is one of the most common symptoms.
In other words, children diagnosed with Autism Spectrum Disorder, have deficits in social interaction. Secondly, signs like very restricted repetitive patterns of behavior, interests, or activities are also seen. Children with ASD are unable to give joint attention. Furthermore, children diagnosed with autism are extremely sensitive to sound. In addition to that, they find it very difficult to adapt to even the slightest change in their surroundings.
Many consider autism to be untreatable. But, mild and moderate cases can be treated to some extent with proper guidance and frequent therapy. Furthermore, the child can learn to do small daily tasks gradually.
Symptoms for Autistic Spectrum Disorder

- Repetitive behavior pattern. Children diagnosed with ASD can tend to do the same task repeatedly. For instance, running around in the house. This playful task can go on for a very long time.
- Secondly, they have an extremely restricted pattern in each and every aspect. Even the slightest change is difficult to adapt to. For instance, a child has bread & butter every day for breakfast. But, one fine day, the mother decides to give him jam & bread. This transition might seem very small for anyone. However, for a child diagnosed with ASD, it is a very huge change. Furthermore, there is a possibility that the child will create a tantrum and make a big fuss about it.
Signs Related to Emotions and Connection with Others.

- Children with ASD, try to avoid contact & interaction with others.
- Paying attention to a particular aspect is very challenging.
- Lack of eye contact with anyone. For instance, a lack of eye contact with the primary caregiver is the initial sign of ASD.
- Children diagnosed with ASD, repeat behaviors, sentences, play, and any pattern which they feel like.
- It is challenging for them to indulge in pretend play. For instance, when girls are small, they pretend to cook food, in their play utensils. This playful activity is not there in children with Autistic Spectrum Disorder.
- They have an extreme fear of simple and ordinary things in their surroundings. For instance, it can be an object, event, or even an activity. In other words, a child diagnosed with ASD can be scared of even a toy that is given to them as a present.
Symptoms related to Language, Communication & Interactions.
- Children diagnosed with ASD, have difficulty understanding simple directions. For instance, a mother trying to teach a child how to color within the lines of a drawing. It is challenging for a child with ASD to understand this simple instruction.
- Repetitive speech. In other words, also known as echolalia. This is a particular sign where the child repeats everything. For instance, a parent has told their child Ben to go to his room. Consequently, he would repeat the sentence “Ben, go to your room” repeatedly for a long time. This repetitive speech happens until they find another activity to engage in.
- They find it extremely difficult to express what they feel and want. In early childhood, children learn to use gestures & small words to indicate what they want. For instance, a child would say only the word ‘Milk’, if they wanted to drink milk. This expression through words & small gestures is difficult for children diagnosed with Autism Spectrum Disorder.
Signs related to Sensory-Motor & Regulatory Aspects.

- Children diagnosed with ASD, have intense difficulty adapting to changes in their surroundings.
- They specifically try to avoid any kind of physical contact. For instance, they don’t like being hugged and touched. There is a possibility for children diagnosed with ASD to get irritated and start crying after such gestures. This sign is very subjective. Therefore, for some children, it is a significant sign, while for some others it is present in mild criteria.
- Children with autistic disorder or even symptoms of ASD face challenges in showing what they want. For instance, they are unable to point at things they want to show you.
- Another sign of autism along with others is poor coordination. They find it difficult to do multiple tasks together.
- Children diagnosed with ASD, engage in self-stimulatory behaviors. For instance, they indulge in activities like headbanging, spinning, rapid hand flapping & movement.
All the symptoms mentioned above are subjective. Each & everyone has his/her own unique characteristics. Moreover, a unique style of coping and understanding their surroundings. Furthermore, processing sensory information varies from child to child. For instance, there are some who are over-reactive to sounds. In other words, a normal sound of even bell can be very loud for them. Therefore, the intense over-reactive behavior to it. While some others are under-reactive to loud sounds. A few children diagnosed with ASD, have amazing visual processing ability (remember scripts & several pages, eye for detailed information). On the other hand, some others have extremely strong auditory memories.

Various Sub-type disorders that fall under Autism Spectrum Disorder

- Rett Syndrome– it is rare to find these cases. However, it is connected to the defects in the X chromosome. Therefore, girls are more prone to get this. In this disorder, the development is completely normal in the beginning phase. Gradually, there is a decrease in skills. Secondly, loss of communication, interaction & purposeful hand & body movements also starts taking place.
- Childhood Disintegrative Disorder– this is another rare disorder. This is similar to Rett Syndrome. However, the characteristic signs of this disorder are as follows. Firstly, the individuals experience loss of skills across a varied range of activities. Secondly, the loss of communication. Lastly, the development of the brain is hindered resulting in loss of skills in motor, social & behavioral aspects as well.
