What makes low-functioning autism so challenging? Individuals diagnosed with Level 3 autism need more support than their peers. Their symptoms are more pronounced and affect daily functioning to a great extent.
Challenges include social difficulties, trouble with verbal and nonverbal communication, and rigid behavior. Treatments for severe autism are available and are most effective when implemented early.
What is low-functioning autism?
The difference between high functioning autism vs. low functioning autism is behavioral. Low-functioning autism, also known as severe autism, can lead to behaviors that make daily life activities difficult.
Children with high functioning autism, on the other hand, have similar abilities to their neurotypical peers.
This is especially true when the child receives early intervention therapies. Children diagnosed with low functioning autism need more support. They struggle to communicate and manage their behaviors.
Symptoms of autism often appear in infancy or early childhood. Autistic children may not reach developmental milestones on time or may skip them entirely.
It might take them longer to learn how to self-soothe, build relationships, and talk. Communication and behavior challenges are typically significant.
Children with low functioning autism struggle to complete activities of daily living. They generally need help with most activities.
Children with severe autism are more likely to have co-morbid conditions. These include such as Fragile X syndrome, tuberous sclerosis, and epilepsy.
High-functioning vs. low-functioning autism
Autism is often described as a spectrum because it affects people differently.
High-functioning autism refers to individuals who may need less support in their daily lives.
They can usually communicate verbally and manage many tasks independently, although they may still struggle with social skills, sensory issues, or other challenges.
Low-functioning autism, sometimes associated with severe autism, involves greater difficulties with communication, behavior, and daily living skills.
People with severe autism may be nonverbal, need help with basic tasks, or display behaviors like meltdowns or self-injury.
It’s important to understand that terms like high-functioning or low-functioning autism don’t capture the full picture.
Although there’s a difference between high-functioning vs. low-functioning autism, every autistic individual has unique strengths and challenges, and their support needs can vary widely.
Severe autism symptoms
Doctors can identify the low functioning autism symptoms as early as infancy. Even more noticeable symptoms presented by preschool age.
Research lists the following as symptoms of severe autism:
- impaired social interaction
- communication difficulties
- obsessive-compulsive disorder, anxiety, and behavior
- sensory processing issues
Impaired social interaction
Social interactions for children with severe autism ranges from difficult to near impossible.
Some children hit milestones and then experience regression.
Skills acquired between the ages of three and five experience the most regression, while other children never develop them.
Inappropriate responses are hallmark signs of low functioning autism. A child with Level 3 autism might laugh when a peer is in pain or display a lack of engagement. Most children will display a lack of social responsiveness.
This might present as limited eye contact, no acknowledgment of others, and rare smiling. Children with autism generally have a hard time comprehending facial expressions.
Poor nonverbal communication skills are more pronounced in low functioning children. Their faces often remain blank even as they are experiencing pain.
Socializing with children can be particularly difficult for those with low-functioning autism. Imaginative play might be boring, and many children struggle to maintain game rules. Others find engaging in group play impossible or uninteresting.
Initiating conversations can be difficult, and maintaining them is even harder. Some children communicate in social settings by using single words or short phrases. Labeling items can be helpful.
Change, whether in a regression or the home routine, can be difficult for children with low-functioning autism. They may become uncooperative, resistant, passive, aggressive, or disruptive.
These reactions can make friendships hard to establish and maintain. Parallel play is an alternative for children who are not overwhelmed by their peers.
Communication issues
Difficulty communicating is one of the first indicators that a child may have autism.
In infancy, autistic children may not babble or point. By age two, they may not be speaking short phrases. It is common for children who struggle to communicate to have frequent tantrums.
The inability to express hunger, pain, or preferences can be isolating and frustrating.
Children with limited communication skills may not respond to their names or acknowledge parents or caregivers. They might seem to alternate between being withdrawn and showing intense frustration.
By age four, a child with low functioning autism may remain nonverbal. They might continue to experience speech delays or experience speech regression.
Verbal children may speak with an abnormal tone or rhythm, such as singsong or monotone. They may develop language skills and repeat phrases.
Usually, this occurs without the ability to contextualize what they are saying. For example, idioms are a favorite to repeat. A child might say, “You’re the apple of my eye,” over and over with little to no understanding of what the phrase means.
They may also take idioms literally. A cliché such as “It’s raining cats and dogs,” could evoke fear or immense confusion.
Low functioning autistic children may also mimic body language and tone without comprehension. Other children might struggle with literal speech and directions. Building a vocabulary can be a very difficult skill.
Obsessive-compulsive behaviors and anxiety
Children with low-functioning autism often show obsessive-compulsive behaviors triggered by sensory overload or deprivation. They may prefer organizing or lining up toys instead of creating stories.
For example, a child might focus on spinning the wheels of a toy car but ignore their function in moving the car.
Toys are often used differently, like repeatedly flipping a switch instead of playing as intended.
While neurotypical children contextualize toys by age four, this behavior may persist into school years.
Impulse control is a common struggle, leading to fidgeting, stimming, or repetitive speech. Some may engage in self-injurious actions like skin-picking or head-banging.
They often rely on routines, and disruptions can worsen behaviors or cause regression.
In some cases, behaviors like hitting or spitting occur, even in calm settings. These children may not understand why the behavior is inappropriate or seek caregiver approval to change it.s on spinning the wheels of a toy car but ignore their function in moving the car.
Sensory processing issues
Many parents notice sensory processing difficulties as early as their child’s infancy. Children with low functioning autism may find physical touch distressing.
Even touch, which most children find comforting, such as cuddling or handholding, may be uncomfortable for them.
You might notice your child’s movements are clumsy, stiff, or exaggerated. This is common in children with autism, even after their peers have refined motor skills.
Children with sensory processing difficulties struggle to acclimate to their bodies. This is due to a hyper-awareness of movement and sensation.
The transition from walking in humid air to crisp air or from carpet to hard floors can be overwhelming.
These children may experience a profound awareness of their senses. Touch and visual stimuli can be particularly distressing.
Despite their extreme sensitivity, many children remain oblivious to self-inflicted pain.
Often, triggering stimuli can change overnight. Constant changes in food and clothing preferences are common.
When should I have my child screened for autism?
If you notice two or more of these signs of autism in your child, it is time to have them screened.
Not meeting typical developmental benchmarks is also an indicator to screen. A multi-disciplinary team will help you with a diagnosis for your child.
The process starts with a questionnaire to determine how your child functions. It will ask about your child’s behavior at home, school, and social settings.
The evaluation might ask for your child’s pediatrician and teacher’s input. If they suspect autism, your child will meet with a team to further test them.
This team is usually comprised of a psychologist/psychiatrist, neurologist, and speech therapist.
An audiologist might administer a hearing test to rule out auditory processing disorders.
Doctors diagnose low functioning autism on three major criteria:
Daily life: They consider the daily impact of behaviors and communication difficulties.with lower functioning autism and weaker verbal skills had the most seizures.
Ability to communicate: Your child’s doctor will assess their verbal skills and nonverbal communication.
Behavior: They will watch for stimming and self-injurious behaviors. The team will pay attention to how restrictive and repetitive the behaviors are.
How to explain low functioning autism to family and friends
After receiving your child’s autism diagnosis, you’ll likely have new questions every day. One thing that most parents struggle with at first is how to explain autism to their friends and family.
Being honest about your child’s diagnosis and how it affects them is important. The more you educate people in your child’s life, the more successful interactions will be.
Give people concrete ideas on how to support your child and interact with them. Explain to family and friends how autism affects your child. To the extent that you are comfortable, provide comprehensive answers to their questions.
People will likely have lots of questions. It is okay to tell people you are still figuring things out. It is fine to say that you do not have all the answers and refer them to a helpful article.
These conversations are ongoing ones. Each time you start a new conversation, it will likely get easier.
How to improve your child’s life with a severe autism diagnosis
Children with low functioning autism have many treatment options to improve their lives. Professional support, in-home modifications, educational opportunities, and community support can be beneficial.
Professional support
Upon receiving a diagnosis, you will need to choose a treatment team for your child. This team usually includes a pediatrician, occupational therapist, speech therapist, and psychologist.
You might also include a psychiatrist to prescribe medication as needed. Autism behavioral therapists can help your child with interpersonal relationships and social skills. Depending on your child’s interests, you might also choose to include an art or music therapist.
In-home modifications
Children with low functioning autism often struggle with impulse control. Many also have a hard time processing dangerous situations. Minimizing risk is one of the most important things you can do for your child.
Locking up hazardous materials, medicine, and cleaning products is a great starting place. Some parents also opt to unplug appliances like stoves and blenders.
If your child engages in head-banging, be sure to add padding to surfaces they use for self-injury. Try creating a secure space in your home where your child has free range to play and explore.
This space might include a yoga ball chair, weighted blanket, and favorite toys. Your child’s pediatrician/occupational therapist can help you identify hazards.
Educational opportunities
Children with low functioning autism deserve exceptional education. Some parents send their children to specialized schools for autism education. Other families prefer accommodations in traditional schools.
Individualized Education Plans (IEPs) are necessary for most public schools. IEPs outline your child’s strengths and struggle to ensure the school meets their needs. An educational psychiatrist will draft the IEP with your child’s treatment team.
The psychiatrist will meet with you and ask for your input. Then, they will form a plan that supports your child’s goals. Many schools offer support staff or paraprofessionals to assist students throughout the day.
Your child’s IEP might specify speech therapy, occupational therapy, or recreational therapy. Some schools even staff a psychologist and psychiatrist.
Community support
Support groups for parents are available through most major hospitals. Groups are often led by a therapist, medical student, or another parent. These groups are a safe place to voice frustrations and celebrate successes.
Some hospitals also offer specialized short-term groups to teach parents practical skills. These skills empower parents to help their children lead a safe and happy life.
Understanding and supporting children with low functioning autism
Children with low-functioning autism face unique challenges that affect their daily lives, but with patience, understanding, and tailored support, they can thrive. Recognizing their needs, embracing their differences, and creating a structured, compassionate environment can make a significant difference in their well-being and development.
