What Are The Three Main Symptoms Of Autism

Autism Spectrum Disorder Definition And Facts

Autism is a complex developmental disorder that has the following three defining core features:

A number of other associated symptoms frequently coexist with autism.

• Most people with autism have problems using language, forming relationships, and appropriately interpreting and responding to the external world around them.
• Autism is a behaviorally defined developmental disorder that begins in early childhood.
• Although the diagnosis of autism may not be made until a child reaches preschool or school age, the signs and symptoms of autism may be apparent by the time the child is aged 12-18 months, and the behavioral characteristics of autism are almost always evident by the time the child is aged 3 years.
• Language delay in the preschool years is typically the presenting problem for more severely affected children with autism. Higher functioning children with autism are generally identified with behavioral problems when they are aged approximately 4-5 years or with social problems later in childhood.
• Autism disorder persists throughout the person’s lifetime, although many people are able to learn to control and modify their behavior to some extent.

All of these disorders are characterized by varying degrees of problems with communication, social interaction, and atypical, repetitive behaviors.

Where Can I Get Information About Support Groups And Counseling For Autism

Having a child diagnosed with autism can be a devastating experience for many parents and families. They may feel frustrated, confused, and afraid-they may even “grieve” for their “normal child.”

Living with autism presents many new challenges for the person with autism and for his or her family and friends.

Parents of autistic children certainly have many worries. They wonder if their children will be able to achieve, if they will be able to be independent, and if they will be able to be happy and enjoy life. Parents also probably have many worries about how the autism will affect them and their ability to live a normal life, that is, to care for their family and home, to hold a job, and to continue the friendships and activities they enjoy. Many people feel anxious and depressed. Some people feel angry and resentful others feel helpless and defeated.

For most people who have a child with autism, and even for some with autism themselves, talking about their feelings and concerns helps.

Friends and family members can be very supportive. They may be hesitant to offer support until they see how you are coping. Don’t wait for them to bring it up. If you want to talk about your concerns, let them know.

Common Signs Of Asd In Preschoolers

With some children, the signs of autism might not become entirely obvious until they reach preschool , when suddenly the developmental gap between them and their peers becomes more pronounced.In addition to the signs for babies/toddlers, here are some of the more common ways ASD might present itself in a preschool-aged child.

Social communication red flags

• The child generally does not point to or share observations or experiences with others
• The child tends not to look directly at other people in a social way. This is sometimes referred to as a lack of eye contact
• There may be an absence of speech, or unusual speech patterns such as repeating words and phrases , failure to use âIâ, âmeâ, and âyouâ, or reversal of these pronouns
• Unusual responses to other people. A child may show no desire to be cuddled, have a strong preference for familiar people and may appear to treat people as objects rather than a source of comfort
• The child may appear to avoid social situations, preferring to be alone
• There is limited development of play activities, particularly imaginative play
• There may be constant crying or there may be an unusual absence of crying

Behavioural red flags

âShe was so distant from us we found it hard to engage her. We would have to say her name at least six times before she would acknowledge us, often staring into space as if in a trance. We put this down to a hearing problem but test results showed otherwise.â

What Age Does Autism Usually Show Up

Some children show ASD symptoms within the first 12 months of life.

In others, symptoms may not show up until 24 months or later.

Some children with ASD gain new skills and meet developmental milestones, until around 18 to 24 months of age and then they stop gaining new skills, or they lose the skills they once had..

Fixation On Particular Subjects Or Ideas

Continually discussing the same topics in conversation, obsessively playing the same song repeatedly, or reading every article written about a certain topic are some ways that autistic fixations can manifest. These interests can be negative if they take over the individuals life or interfere with their relationships with others. Of course, these obsessive tendencies can also be helpful Dan Aykroyd, writer and star in the hit film Ghostbusters, was inspired by his focus on ghosts and the paranormal. Many other high-functioning autistic individuals have used their focus on mathematics, biology, or writing to inspire successful careers.

Signs And Symptoms Of Autism Spectrum Disorders

Autism spectrum disorder is a developmental disability caused by differences in the brain. Some people with ASD have a known difference, such as a genetic condition. Other causes are not yet known. Scientists believe there are multiple causes of ASD that act together to change the most common ways people develop. We still have much to learn about these causes and how they impact people with ASD.

There is often nothing about how people with ASD look that sets them apart from other people. They may behave, communicate, interact, and learn in ways that are different from most other people. The abilities of people with ASD can vary significantly. For example, some people with ASD may have advanced conversation skills whereas others may be nonverbal. Some people with ASD need a lot of help in their daily lives others can work and live with little to no support.

ASD begins before the age of 3 years and can last throughout a persons life, although symptoms may improve over time. Some children show ASD symptoms within the first 12 months of life. In others, symptoms may not show up until 24 months or later. Some children with ASD gain new skills and meet developmental milestones, until around 18 to 24 months of age and then they stop gaining new skills, or they lose the skills they once had.

What Are Some Common Signs Of Asd

Even as infants, children with ASD may seem different, especially when compared to other children their own age. They may become overly focused on certain objects, rarely make eye contact, and fail to engage in typical babbling with their parents. In other cases, children may develop normally until the second or even third year of life, but then start to withdraw and become indifferent to social engagement.

The severity of ASD can vary greatly and is based on the degree to which social communication, insistence of sameness of activities and surroundings, and repetitive patterns of behavior affect the daily functioning of the individual.

Social impairment and communication difficultiesMany people with ASD find social interactions difficult. The mutual give-and-take nature of typical communication and interaction is often particularly challenging. Children with ASD may fail to respond to their names, avoid eye contact with other people, and only interact with others to achieve specific goals. Often children with ASD do not understand how to play or engage with other children and may prefer to be alone. People with ASD may find it difficult to understand other peoples feelings or talk about their own feelings.

Signs Of Autism In Girls

The ratio of boys to girls diagnosed with autism spectrum disorder is 4:1. However, there is some evidence that autism is going undiagnosed in girls, particularly those who are at the higher functioning end of the spectrum.

There is discussion around whether girls and women with autism may display different symptoms to boys and men, and that the current diagnostic criteria may be biased towards boys and stereotypical male behavior. Girls and women may also be better able to mask difficulties with social interactions than boys, and this may delay a diagnosis. New diagnostic criteria may be needed to assess ASD in girls and women. Past theories, including controversies such as the extreme male brain, may have led to under-referral and under-diagnosis of autism spectrum disorder in girls and women.

Signs that a girl may have autism include:

• Difficulties with social interactions however, differences from typical autism symptoms may include:
• Better grasp of emotions and ability to make friends than boys
• May mask lack of intuitive understanding of social situations by repeating role-plays seen in real life or film/television
• May be able to make friends but find difficulty keeping them

Signs Of Autism Meltdown

For some people with autism, sensory overload can become overwhelming. In these situations a person may have a meltdown. A change in routine can also precipitate a meltdown.

A meltdown is not a temper tantrum and can be experienced by someone with autism of any age. A meltdown should be managed by calming the person and addressing the cause of the distress.

Signs that a meltdown may be developing, sometimes known as the rumbling stage, include:

• Nail biting

• Chronic gastritis
• Chronic duodenitis

Many people with autism spectrum disorder also have food intolerances and may find that a diet which excludes gluten or casein helps.

How Does Autism Affect Kids

Autistic children may not reach the same developmental milestones as their peers, or they may demonstrate the loss of previously developed social or language skills.

For instance, a 2-year-old without autism may show interest in simple games of make-believe. A 4-year-old without autism may enjoy engaging in activities with other children. An autistic child may have trouble interacting with others or dislike it altogether.

Autistic children may also engage in repetitive behaviors, have difficulty sleeping, or compulsively eat nonfood items. They may find it hard to thrive without a structured environment or consistent routine.

If your child is autistic, you may have to work closely with their teachers to ensure they succeed in the classroom.

Many resources are available to help autistic children as well as their loved ones. Local support groups can be found through the national nonprofit The Autism Society of America.

What Is The Outlook For People With Autism Spectrum Disorder

In many cases, the symptoms of ASD become less pronounced as a child gets older. Parents of children with ASD may need to be flexible and ready to adjust treatment as needed for their child.

People with ASD may go on to live typical lives, but there is often need for continued services and support as they age. The needs depend on the severity of the symptoms. For most, it’s a lifelong condition that may require ongoing supports.

A note from Cleveland Clinic

Do Symptoms Of Autism Change Over Time

For many children, symptoms improve with age and behavioral treatment. During adolescence, some children with ASD may become depressed or experience behavioral problems, and their treatment may need some modification as they transition to adulthood. People with ASD usually continue to need services and supports as they get older, but depending on severity of the disorder, people with ASD may be able to work successfully and live independently or within a supportive environment.

No Link Between Autism And Immunisation

Any link between immunisation and autism has been completely discredited.

During the 1990s, concern in the community about a possible link between the measles, mumps, rubella vaccine and autism was generated by the findings of research conducted in London in 1998. The Wakefield study has since been discredited and withdrawn by the journal that originally published it. Dr Wakefields registration as a doctor in the United Kingdom has also been cancelled.

Extensive research conducted globally for a decade did not establish any link between vaccines and autism.

Diagnosing Autism Spectrum Disorder

In order to determine whether your child has autism spectrum disorder or another developmental condition, clinicians look carefully at the way your child interacts with others, communicates, and behaves. Diagnosis is based on the patterns of behavior that are revealed.

If you are concerned that your child has autism spectrum disorder and developmental screening confirms the risk, ask your family doctor or pediatrician to refer you immediately to an autism specialist or team of specialists for a comprehensive evaluation. Since the diagnosis of autism spectrum disorder is complicated, it is essential that you meet with experts who have training and experience in this highly specialized area.

The team of specialists involved in diagnosing your child may include:

Diagnosing Autism Spectrum Disorder is not a brief process. There is no single medical test that can diagnose it definitively instead, in order to accurately pinpoint your childs problem, multiple evaluations and tests may be necessary.
