There Are 5 Different Types of Autism Disorders

Autism is a complex developmental disability with many different levels of severity. Technically, there is one diagnosis that is Autism. People do however refer to the Pervasive Developmental Disorders as disorders on the Autism spectrum or Autism Spectrum Disorders (ASD). Autism Spectrum Disorders are developmental brain disorders that cause impaired social interaction, problems with verbal and nonverbal communication, and unusual, repetitive, or severely limited activities and interests. Autism is just one of five different types of Autism disorders.

Below are definitions and characteristics of the five different autism disorders.

Classic Autism:

Autism is the second leading childhood developmental disorder and is considered the most severe of the different types of Autism disorders. People with Classic Autism develop language late, or not at all. People affected with Classic Autism have difficulties talking with other people or a profound lack of affection or emotional contact with others, an intense wish for sameness in routines, muteness or abnormality of speech, high levels of Visio-spatial skills, but major learning difficulties in other areas. Symptoms of autism usually appear during the first three years of childhood and continue throughout life. Autism is a spectrum disorder because the severity of impairment in each of these areas differs in each individual.

Aspergers Syndrome:

A Person with Aspergers Syndrome can exhibit a variety of characteristics and the disorder can range from mild to severe. Children show deficiencies in social skill and have difficulties with transitions or changes. They compulsively cling to rituals and any changes in their routine can upset them. They have a great difficulty reading body language and determining proper body space. Some children with Aspergers Syndrome have reduced sensitivity to pain and an increased sensitivity to bright lights and loud noises. With this type of Autism disorders they also have average or above-average intelligence.

Childhood Disintegrative Disorder:

Childhood Disintegrative Disorder includes severe regression in communication skills, social behavior, and all developmental motor skills. At the beginning these children seem perfectly normal. They start to regress at between ages 2-4 years. At that time these children stop socializing, lose potty-training skills, stop playing, lose motor skills and stop making friends.

Rett Syndrome:

Rett syndrome is a neurological and developmental disorder that mostly occurs in females and is marked by poor head growth. Loss of muscle tone is usually the first symptom. Other early symptoms may include problems crawling or walking and diminished eye contact. They stop using their hands to do things and often develop stereotyped hand movements, such as wringing, clapping, or patting their hands. The inability to perform motor functions is perhaps the most severely disabling feature of Rett syndrome, interfering with every body movement, including eye gaze and speech. Infants with Rett syndrome seem to grow and develop normally at first, but then stop developing and even lose skills and abilities.

Pervasive Developmental Disorder-Not Otherwise Specified:

This tends to describe people who have many or all of the different types of Autism disorders. Children with PDDNOS either do not fully meet the criteria of symptoms used to diagnose any of the four specific types above, and/or do not have the degree of impairment described in any of the above four specific types.

Parents Need to Recognize Autism Signs in Their Children

Autism is one of the fastest growing neurological disorders, with as many as one in every 95 children diagnosed with the disorder. Autism signs vary among individuals, of course, but there are some common characteristics that you should watch for. Children with autism have trouble relating to others, sometimes markedly so. The nuances most people pick up on during social interaction elude them to the point where they become very socially disabled indeed, and can become extremely isolated. With early intervention, autism can be managed quite well, sometimes with few effects depending on the severity of the original disorder and the age at which the child was diagnosed.

First noticing autism signs

Most professionals think that autism begins while still in utero, but it can be difficult to see these signs when children are very, very young. By about the age of three, though, there are many common characteristics definitely present; many parents will also often think that there is simply “something wrong” in a vague sort of way with their child at a much earlier age.

Early intervention is key

Following are some signs you should be concerned about in your child that may not just be “developmental” or “a stage.” Early intervention is key, so if you suspect your child may have autism based upon one of the following symptoms, get him or her to a doctor for diagnosis as soon as possible. The earlier the intervention, the more successful it is.

Autism signs in very young children

Even in infancy, many children with autism don’t like to be held and in general have an aversion to being touched. They may also lack the ability to establish or be very uncomfortable with eye contact. Even babies as young as six months old like the game of “peekaboo,” and if your child does not like these types of games or doesn’t seem to be able to engage, this should be a sign of concern within a few months of age.

Autism signs at older ages

As a child grows older, he or she should become more verbal and should begin to speak. Yet, if your child can’t say simple words or phrases (and doesn’t seem to make the normal cooing or babbling sounds most babies make) by the age of several months to a year old, it’s also a sign of concern. In some cases, parents often think their children may have hearing difficulties, but the hearing itself appears to be selective. That is, they obviously react to some sounds just fine, but don’t seem to be able to hear others.

Alternatively, these children also often exhibit what’s called “echolalia,” in which they mimic exactly the sounds or words they hear, in pitch, tone, etc. This is different than the type of mimicry young children do when they’re learning how to speak, since it appears to be mere repetition as one might hear from a recording instead of an actual attempt to speak.

Other autistic behaviors

Autistic children also exhibit intensive concentration on specific things, especially mechanical things; they may also exhibit so-called “isms,” whereby they engage in repetitive movements, tongue clicking, et cetera.

Possible causes of autism

The actual causes of autism are not known, although most suspect it’s a neurological disorder that begins in utero. Some have suspected infection, certain vaccination combinations, or being ill at very young ages with high fevers may also contribute to the onset of autism. Still other causes are purported to be immune system response to allergies, et cetera. As yet, though, no definitive actual cause has been found.

Getting autism signs diagnosed and treated

With early intervention, children can significantly improve their ability to relate to others. Although most children with autism will have some residual effects, they will significantly improve their ability to relate to others and may even be able to live on their own once older and function very well, even living normal or nearly normal lives. Most children with autism, contrary to popular belief, are not completely isolated and do not “live in a world of their own,” especially if they are given early and intensive treatment.
