Autism and oral fixation are linked through sensory processing disorders. It involves chewing on things to alleviate anxiety and stress. Oral fixation is when you feel the need to chew, suck, or hold an object in your mouth. This behavior is common for babies, but generally alleviates as the child ages.
The sensory receptors in the mouth provide them with information about the item, such as texture, size, taste, temperature, shape, etc. Mouthing items, or oral sensory seeking behavior, is typical for babies and infants, and it aids with self-regulation.
Children with atypical oral processing may respond in a heightened way to oral input; this is called oral hypersensitivity (or oral aversion or defensiveness). These children may be considered “picky” or “selective” eaters, choke or gag easily, resist utensils, and/or resist tooth brushing or the dentist.
Autism and ASD - Stimming behaviors are commonly associated with Autism Spectrum Disorders. This may not always present itself in the form of an oral fixation, but many children will use chewing or biting items as a way to reduce anxiety and cope with sensory overload.
Perhaps your child will grow out of this phase or can be offered an alternative such as chewing gum. However, in many cases, the need for oral stimulation is stronger, does not just go away and needs to be addressed with more appropriate chewing tools.
Yes! Although they sound similar, sensory processing difficulties can be present without autism. Often children or adults with other neurodevelopmental or psychiatric conditions such as Developmental Delay, Intellectual Disability, Anxiety, ADHD, or mood disorders can also exhibit Sensory Processing Disorder.
If your child has a sensory problem, the medical team may recommend desensitization therapy (repeated exposure to problematic foods or textures) or may suggest modifying what or how your child is fed (for example, changing the type of utensil or cup) until your child's feeding abilities improve.
What is Mouthing? Mouthing is a common behavior in children with autism spectrum disorder (sometimes confused in infants for teething) that involves inserting an inedible object into their mouth for the purposes of sensory stimulation.
Bruxism (20-25%) • Non-nutritive chewing • Tongue thrusting • Self-injury (picking at gingiva, biting lips) creating ulcerations.
Children with autism have a broader or wider mouth and philtrum - the groove below the nose, above the top lip.
When a child struggles with sensory processing disorder, not only is his/her daily behavior affected, but also the acquisition of speech can be impaired. Many children with SPD are also diagnosed with a speech delay or aphasia, a difficulty in conveying spoken language.
What causes of oral-motor and oral-sensory problems? Both oral-motor and oral-sensory problems are caused by problems with nerves. Adults may develop these kinds of feeding problems after a stroke or head trauma. But when children develop oral-motor and oral-sensory problems, the cause is less clear.
Sensory processing disorder is not recognized as a formal medical diagnosis on its own, but it may exist separate from a diagnosis of autism. Difficulties with sensory processing are an indicator of autism; however, not all children with autism will also struggle with sensory issues and SPD.
Depending on the severity of a child's Sensory Processing Disorder, a child may or may not outgrow it. In less severe cases, a child may have an underdeveloped sensory system, and once their sensory system matures and develops, they might outgrow some of their sensory symptoms.
Attention deficit hyperactivity disorder (ADHD) and sensory processing disorder (SPD) share similarities, but they aren't the same diagnosis. Everyone can feel overstimulated at times, especially if you're in the midst of chaos or you've been feeling stressed in other areas of life.
brain functions. There are two main areas that are affected when an individual has ASD: ● social-communication skills, and ● restricted and repetitive behaviors. Individuals who have been diagnosed with ASD may have difficulty communicating with others, making friends and relating to other people.
People with high functioning autism may exhibit a delay or lack of social skills. They can have difficulty understanding the feelings and reactions of others which can make them appear to be insensitive at times. Some people may struggle to interact and insist on talking about things they are passionate about instead.
While mannerisms such as random humming or screaming are known as vocal stims, echolalia and palilalia are known as verbal stimming. This is because vocal stimming involves the use of sounds other than talking, whereas verbal stimming usually involves speech.
Just like sniffing, mouthing and licking might be another way for an ASD child to explore the world around them. It can also be a comforting habit.
Children with ASD are often unable to use gestures—such as pointing to an object—to give meaning to their speech. They often avoid eye contact, which can make them seem rude, uninterested, or inattentive.
Nonverbal autism is a form of autism that is characterized by a lack of or limited use of verbal communication. This can include difficulty using words to express needs or desires, speaking in single words or short phrases, and difficulty understanding language.
The long answer, most will stop putting things in their mouth by the age of three. It tends to be a lot of mouthing during infancy. Then a bit of mouthing in the early toddler years. Then as they near three, they tend to understand food is for mouths and other objects may pose a risk.
Occupational therapy can help kids cope with sensory issues. They learn ways to give themselves the right amount of stimulation, maybe with a heavy vest, a fidget toy or ear plugs. Some kids grow out of these issues completely. Some kids, especially autistic kids, have them their whole lives.
Due to sensory sensitivities, someone with autism might: display unusual sensory seeking behaviour such as sniffing objects or staring intently at moving objects. display unusual sensory avoidance behaviours including evasion of everyday sounds and textures such as hair dryers, clothing tags, vacuum cleaners and sand.
