Autism and Tics: Is There a Connection?

As you watch your autistic child twitch their nose and shrug their shoulders repetitively, you probably wonder about autism tics. Are they simply a form of repetitive behavior, or are autism and tics something more complex? 

Many parents look for an autistic tics list that can help them better understand their child’s repetitive behavior. Unfortunately, no checklist could suit each child on the spectrum. There is much more to tic disorders than just facial twitching and shoulder jerks.

What are tics?

Tic disorders are neurodevelopmental conditions that often emerge in childhood. They may occur together with attention deficit hyperactivity disorder (ADHD), autism, or obsessive-compulsive disorder (OCD).

Children with autism may also experience tics, sometimes called autistic tics, which can add to the complexity of symptoms.

A tic can be described as a brief movement or sound that interrupts normal behavior. Tics are involuntary movements or vocalizations that happen suddenly and repetitively.

Although the behavior is often repeated, it is not rhythmic.

Your autistic child may also have ADHD or other co-occurring conditions, which can sometimes make it harder to tell symptoms apart.

This is why it’s so important to seek an accurate diagnosis that considers your child’s medical history and any coexisting conditions.

Repetitive behaviors, such as rhythmic hand waving in front of the face, are linked to autism spectrum disorders. These movements are often referred to as stereotypies and can look different from tics.

Tic disorders

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) lists three main types of tic disorders to help professionals make a diagnosis:

• Tourette Syndrome: A complex neurodevelopmental condition diagnosed when a child has two or more motor tics and at least one vocal tic. Motor tics include actions like head twitching, blinking, and shoulder shrugging, while vocal tics involve sounds such as throat clearing, grunting, or yelling.
• Persistent (Chronic) Motor or Vocal Tic Disorder: Diagnosed when a child has either motor tics or vocal tics (but not both) for more than a year.
• Provisional Tic Disorder: Occurs when tics begin before the age of 18, last less than one year, and the child has never met criteria for Tourette syndrome or Persistent tic disorder.

Understanding autism tics

Autistic tics, also known as stimming or self-stimulatory behavior, are repetitive movements, sounds, or actions that children and adults with autism spectrum disorder may engage in. 

These behaviors serve many purposes for autistic individuals, like calming themselves or coping with overwhelming situations, and can vary widely from person to person.

Autism tics can take many forms, including hand flapping, vocalizations, or specific routines, and they are often confused with stereotypies. But what are stereotypies?

They are rhythmic, repeated movements that seem purposeless. Unlike tics, there’s no premonitory urge before doing them or sense of relief afterward.

Stereotypies usually appear earlier than tics. They often start before a child turns three, while tics mostly begin when a child is around six years old.

Some common autism tics examples of motor tics include:

• rocking back and forth
• licking lips
• flapping hands
• blinking

Some common vocal autistic tics are:

• grunting
• repeating words or phrases
• yelling and screaming

Even if you notice repetitive behaviors that look like tics, it’s important to work with a professional to figure out whether your child has Tourette’s syndrome, autism-related tics, or another tic disorder.

For an accurate diagnosis and early support, try to share as many details as you can about when the behaviors started and what they look like.

The effect of autism and tics on adults and children

People often describe a specific sensation before experiencing a tic. These feelings are common in both Tourette syndrome and autism and tics, and they can be challenging for children and adults to manage.

Common sensations before a tic include a feeling of energy that needs to escape, an inner sense of being wound up, and overall tenseness.

Many people notice that these sensations usually go away after completing the tic.

I remember suppressing a dry cough as a child in a quiet church. The urge to cough was intense, but the thought of letting it out was both horrifying and relieving.

It’s challenging for a young child to cope with urges that are only eased through behaviors others might not understand. This is especially true in school settings where differences can lead to teasing or embarrassment.

Children who experience tics often face more bullying, social difficulties, and school challenges, including falling behind academically.

While Tourette syndrome is considered the most severe tic condition, many childhood tics are temporary and often go away on their own within a few months. 

Encouragingly, behavioral strategies and early support can help reduce the impact of chronic tics.

Tic suppression and support

Children with tics can sometimes learn to suppress them, especially when they feel motivated and supported.

Suppression tends to be more successful when children are given positive reinforcement, like small rewards or encouragement.

This shows that even when tics feel uncontrollable, children can build skills to manage them over time with the right guidance.

Positive outcomes and early help

Early intervention plays an important role in supporting children with autism and tics. 

Behavioral approaches, therapy, and consistent support can prevent tics from becoming more disruptive as children grow older.

Parents should never feel like they have to ignore repetitive or interfering behaviors as just another part of autism.

Reaching out for help, exploring therapy options, and celebrating small successes can make a meaningful difference in your child’s daily life and confidence.

FAQs

Q: Are tics a sign of autism?

A: Tics are not considered a core sign of autism, but they can occur alongside it. Many autistic people also have conditions like Tourette syndrome or experience repetitive movements that resemble tics.

Q: Can people with autism get tics?

A: Yes, people with autism can have tics. These may include sudden, repetitive movements or sounds that are difficult to control.

Q: Can autism cause twitching?

A: Autism itself doesn’t directly cause twitching, but some individuals may have motor tics or repetitive behaviors that look like twitching. Sensory overload or anxiety can also trigger movements that seem like twitches.

Q: What do autistic tics look like?

A: Autistic tics can appear as rapid eye blinking, shoulder shrugging, facial grimacing, or vocal sounds like grunting. They often look similar to tics seen in tic disorders such as Tourette syndrome.

Q: What are functional tics in autism?

A: Functional tics are movements or sounds that resemble tics but arise from psychological or functional neurological factors rather than a neurological tic disorder. In autism, these may develop in response to stress, anxiety, or social factors.
