What Are Causes Of Autism Spectrum Disorder – Autism symptoms vary among people with autism spectrum disorder (ASD). While autism affects both children and adults, symptoms usually appear when the child is between 18 and 24 months old. Autism is considered a developmental disorder because it often appears in the first two years of life… However, this does not mean that it cannot be diagnosed at another time, such as adolescence or adulthood. Autistic disorders begin when children are young. There are many different autism symptoms and each can range from mild to severe, so each person with autism is unique and can benefit from an individualized intervention plan for their health, behavior and mental health.
According to the Centers for Disease Control and Prevention (CDC), extensive research has shown that the brains of people with autism develop differently than their peers without ASD. This difference in brain development is responsible for the problems that people with autism face.
What Are Causes Of Autism Spectrum Disorder

Autism spectrum disorder is a lifelong disability; However, this does not mean that life cannot be lived to the fullest. Symptoms can be managed if there is a treatment plan and the intervention of professionals such as behavior analysts or applied therapists. You may have questions “Is head shaking a sign of autism?” or “my child is throwing his head back with autistic behavior?” In this article, you will learn about the 10 most common symptoms of autism spectrum disorder and an explanation of each.
Autism Spectrum Disorder
It is important to note that there are differences in the symptoms of autism shown by adults and children. As children move through adolescence and later adulthood, the signs and symptoms of autism can also change.
Autism can affect a child’s development. Some people with autism spectrum disorders may also have developmental learning delays, such as having specific learning disabilities or delays in reaching developmental milestones. For example, a person may have difficulty learning basic skill concepts such as personal hygiene or following simple one-two-step directions. At each stage of a child’s development, there are specific “red flags” that parents, teachers, and doctors should be aware of that may indicate a problem. These early signs or “red flags” can appear suddenly or over time.
For example, people with autism are very sensitive to sensory stimuli such as loud noises, bright lights or the touch of certain clothes. The brain’s ability to process physical stimuli works differently than that of someone without autism. As a result, people with autism often get bored easily. This onslaught of information can be scary or confusing… or downright frustrating.
Some other examples of autism symptoms may be intolerance to the taste of spicy foods and a preference for bland food. Or because of increased skin sensitivity, they may not tolerate well.
Types Of Autism Spectrum Disorder
At the other end, a person with autism may be less sensitive to their environment. They may not be able to follow different stimuli and may seem immune to situations that others find impossible. Examples of this might be like a child with autism hitting their head, asking for a heavy leash, or getting upset.
When the child is 12-15 months old, he should be able to answer simple questions, such as nodding his head “yes” or “no” when asked a simple question. At this age, a person should try to say words like “mama” and “papa”. They may also begin to imitate small words they hear often, such as “yay” or “uh-oh.” Children who show signs of autism spectrum disorder may have a language deficit. They may not speak at all, or they may begin to remain silent for long periods of time. They may refuse to try to communicate with others, even people they love and trust.
Communication is not just verbal; This includes reading facial expressions and eye contact, recognizing tone of voice as well as understanding gestures. In general, the ability to communicate depends to some extent on the social and intellectual development of the child.

Repetitive actions and behaviors, such as deliberately moving the head, legs or arms, deliberately making facial expressions or pulling hair, can be signs of autism. Head shaking in autism is often accompanied by head banging or other repetitive movements. Parents may ask, “Is hair pulling a sign of autism?” Although hair pulling is a symptom of autism, hair pulling itself will not be a symptom of ASD.

“Researchers divide repetitive behaviors into two groups. So-called ‘lower order’ repetitive behaviors include sounds such as waving hands, shaking objects or body movements, and shouting or repeating certain phrases. Characteristics such as emphasis on routines and rituals, similarities and interests intense,” (Spectrum News).
If you notice that your child often exhibits certain repetitive behaviors that are related to the task they are doing or the environment they are in, you may want to tell your doctor about the behavior patterns.
One of the most easily recognized symptoms of autism is difficulty socializing with others. Children and adults with autism spectrum disorders are affected when placed in highly stimulating social environments. They are sometimes mistakenly labeled as “loners” or introverts. People who are “loners” prefer to spend time alone and enjoy their company rather than the company of others.
According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), a person must show persistent deficits in the following three areas to be diagnosed with autism:
What Parents Need To Know About Autism
People with autism spectrum disorder have difficulty forming relationships with others when placed in situations that require social interaction. One way to deal with this is to block out what is happening around them.
People with autism spectrum disorder often have a certain routine that they feel they must follow. Having a routine in performing daily tasks can provide peace of mind for people with autism. A stable, self-regulating schedule helps the anxious mind. But life is rarely predictable. Unexpected events can occur and disrupt normal routines. Small changes that disrupt the map can cause problems. Big life changes, such as starting school or graduating, can cause some people with autism to feel anxious because of a sense of loss of control. If this person hasn’t learned self-control, they may have panic attacks or “breakdowns.”
They use these to announce changes and changes in the daily schedule. Storyboards and social stories can be easily created online or ordered through a specialized ASD teaching website. They can be tailored to the child’s specific situation and needs.

These autism symptoms can be managed in a similar way in adults. Adults may need help with time management in the workplace. A person with autism spectrum disorder who needs help with work may benefit from dividing their day into predictable parts. Just telling them that they will be working from 7am to 3pm may not be enough information for them to succeed.
Causes Of Autism
One of the most common signs of autism in children and adults is a strong interest in unusual objects or subjects, almost to the point of fascination. For example, an autistic person may experience things like:
People with autism spectrum disorder know what they like and don’t care if it looks “abnormal”. They can also be so passionate that they will spend a lot of time on their interests. Often they become subject matter experts on topics they are passionate about. This is one of the main symptoms of autism in adults. Whether it’s drawing or playing video games, people on the autism spectrum expend endless energy pursuing their hobbies. Most children and adults with autism like to pursue these interests on their own, and there’s nothing wrong with that!
There is a misconception that people with autism lack emotions; This is a complete lie… they have feelings just like everyone else. They simply struggle to understand and interpret emotions. Having an autism spectrum disorder can make it difficult to recognize emotions from facial expressions and body language. People with ASD may not understand common social cues such as raised eyebrows or shrugging of shoulders. It is difficult to easily recognize emotion or sarcasm from someone’s voice. Anger, fear, disgust and surprise are difficult to understand. Therefore, it is common for people with ASD to misunderstand situations and react inappropriately. Autistic disorders cause difficulties in expressing their feelings and experiencing empathy.
Parents, teachers, and therapists should encourage emotional development in young children with autism; It is better to start intervention as soon as possible.

According to Autism Speaks, 80 percent of children with autism spectrum disorders have a chronic sleep disorder, and people with autism are twice as likely to experience regular insomnia. They often struggle to get the recommended eight hours of sleep each night. Unfortunately, not getting enough sleep can make other ASD symptoms worse. Insomniacs with ASD exhibit repetitive behaviors and delays in learning.
