Aspergers Children and Sensory Issues

Children with Aspergers (high functioning autism) may have problems processing information from one or more of the following seven sensory systems:

1. auditory (hearing)
2. gustatory (taste)
3. olfactory (smell)
4. proprioception (movement)
5. tactile (touch)
6. vestibular (balance)
7. visual (sight)

These processes take place at an unconscious level, and they work together to help attention and learning. Each system has specific receptors that pick up information that is relayed to the brain. The sensory characteristics of children with Aspergers can be responsible for many of their negative behaviors and unpleasant emotions. Reactions to sensory stimuli for typically developing children often become stress responses for those with Aspergers.

Sensory System Impact on Children with Aspergers—

1. Auditory System – Hearing: While they have intact hearing abilities, kids with Aspergers may not efficiently or accurately interpret auditory information. They may be hyper- and/or hyposensitive to noise, responding negatively to loud or small noises and failing to respond when their name is called.

2. Gustatory and Olfactory Systems – Taste and Smell: Issues related to the taste system manifest themselves in avoiding certain foods, eating a very circumscribed diet, and/or being very picky about foods. Closely related to the sense of taste, the olfactory system in the nose is most often characterized by a hypersensitivity to many of the smells that others enjoy or fail to notice.

3. Proprioception System – Movement: The proprioceptive system makes carrying multiple objects (e.g., backpack, books, and musical instruments) down a packed hallway possible by providing information about the location and movement of a body part. For some, these movements do not come naturally. Problems in the proprioception system can result in poor posture, a lack of coordination, and chronic fatigue accompanying physical activity. Some children do not receive accurate information from their bodies about how hard or soft they are hitting or pushing something. This can result in their using too little or too much force when tagging a peer or kicking a ball.

4. Tactile System – Touch: The tactile system provides information about objects in the environment. Tactile defensiveness may involve physical discomfort when coming into contact with someone or something that others might not register. Standing in line, taking a bath, unexpected touch, touch that is either too light or too heavy, and using a glue stick present potentially stressful situations for tactilely defensive individuals. In contrast, children who are hyposensitive fail to respond to the touch of others, yet often use touch to explore the environment for the tactile input they crave.

5. Vestibular System – Balance: The vestibular system is stimulated by movement and changes in head position. Children with vestibular hypersensitivity have low tolerance for movement and exhibit difficulties with changing speed and direction. They may experience nausea from spinning and have difficulty sitting still; others may display gravitational insecurity. Some may seek out vestibular input by crashing into things or rocking, might be considered clumsy, or have difficulty “switching gears.”

6. Visual System – Sight: Compared to other sensory areas, the visual system appears to be a relative strength for children with Aspergers. The problems that do arise are often related to hypersensitivities to light, poor hand-eye coordination/depth perception, and hypo-sensitivities that make finding an object “in plain sight” very difficult. Some children may have perfect 20/20 vision yet have difficulties with visual tracking and convergence. These problems can be detected by an exam with a behavioral ophthalmologist or optometrist.

Debra Bennett Mattison This is a great and very informative article. Teachers at school should have this as a "checklist" for dealing with children in their classrooms. I may even give it to my son's teachers. He has issues with several of the 7 listed.

A Little Bloomer LB has "the best nose" as she says. Loud noises are disturbing such as a toilet flushing. As she gets older she can express what bothers her more and we can address it before a meltdown occurs.

My child has been rejected by his peers, ridiculed and bullied !!!

Social rejection has devastating effects in many areas of functioning. Because the ASD child tends to internalize how others treat him, rejection damages self-esteem and often causes anxiety and depression. As the child feels worse about himself and becomes more anxious and depressed – he performs worse, socially and intellectually.

How to Prevent Meltdowns in Children on the Spectrum

Meltdowns are not a pretty sight. They are somewhat like overblown temper tantrums, but unlike tantrums, meltdowns can last anywhere from ten minutes to over an hour. When it starts, the Asperger's or HFA child is totally out-of-control. When it ends, both you and your child are totally exhausted. But... don’t breathe a sigh of relief yet. At the least provocation, for the remainder of that day -- and sometimes into the next - the meltdown can return in full force.

Parenting Defiant Teens on the Spectrum

Although Aspergers [high-functioning autism] is at the milder end of the autism spectrum, the challenges parents face when disciplining a teenager on the spectrum are more difficult than they would be with an average teen. Complicated by defiant behavior, the teen is at risk for even greater difficulties on multiple levels – unless the parents’ disciplinary techniques are tailored to their child's special needs.

Parenting Children and Teens with High-Functioning Autism

Two traits often found in kids with High-Functioning Autism are “mind-blindness” (i.e., the inability to predict the beliefs and intentions of others) and “alexithymia” (i.e., the inability to identify and interpret emotional signals in others). These two traits reduce the youngster’s ability to empathize with peers. As a result, he or she may be perceived by adults and other children as selfish, insensitive and uncaring.
