Is There a Link Between OCD and Autism?
Autistic individuals often use stimming as a way to self-regulate, while those with OCD may exhibit ritualistic behavior that appears similar to stimming. These compulsions are used to alleviate the anxiety associated with obsessive thoughts.
Co-occurrence of Autism and OCD is common, with around 17% of individuals with Autism also having OCD. This prevalence is higher than the general population, where OCD affects only 1.6% of people.
The use of repetitive behaviors as a means of seeking comfort is just one of the many ways that autism and OCD share similarities.
Are OCD and autism the same?
Autism and OCD are separate conditions, but they do have several shared characteristics.
Both involve repetitive behaviors
Although repetitive behaviors in autism and OCD may appear similar, the underlying reasons for them can differ.
Stimming behavior in autism can involve repetitive actions like tapping fingers on a surface. Autistic individuals find this behavior enjoyable, either due to the tactile sensations, the sound, or the visual aspect of finger movement. As such, they have no desire to stop this positive experience.
Any type of repetitive, fidgety behavior that an individual uses to alleviate boredom, anxiety, or sensory overload can be classified as a stim.
Examples include:
- foot tapping
- hair twisting
- nail biting
- finger flicking
- pencil tapping
- whistling
- knuckle cracking
While a person with OCD might engage in similar repetitive behaviors, they are not relaxing or soothing stims. Rather, they are compulsions that the individual feels compelled to perform in order to prevent a negative outcome.
Both involve obsessions
Apart from the commonality of repetitive behaviors, individuals with autism and OCD share other traits.
Autistic individuals often exhibit a deep interest in specific areas and become experts in them. Such interests provide them with comfort and a sense of security, and in certain cases, they can help in professional success.
Nevertheless, in some instances, an area of focus can become all-consuming, taking over an autistic person’s life and interfering with their work or employment. If this area of interest were to disappear, it may leave them feeling like they have nothing else in life.
OCD obsessions are intrusive and unwanted thoughts that do not contribute to professional success.
In some instances, OCD thoughts can be aggressive, such as images of a car driving into a crowd of people, or represent a loss of control, such as thoughts of acting inappropriately in public.
While the nature of obsessions may differ between autism and OCD, they can both have negative effects on focus, attention, and overall well-being.
Both involve anxiety
Anxiety is a shared characteristic experienced by many individuals with autism and OCD.
OCD falls under the category of “obsessive-compulsive disorders and related conditions,” with anxiety being a primary diagnostic criterion. Autism, on the other hand, is a neurodevelopmental condition that includes anxiety as one of its traits.
Although anxiety is a common experience shared by individuals with these conditions, the underlying causes can differ.
Causes of anxiety in autism may include:
- sensory overload
- disruption of routine
- change in environment
- misunderstandings
- social challenges
Causes of anxiety in OCD may include:
- intrusive and unwanted
- interrupted rituals
- fears of bad things happening
- social shame
Both involve rigid thinking
Both autism and OCD can lead to inflexible thinking.
In the case of autism, inflexible thinking can manifest in:
- the need to stick to a routine to feel secure
- social conflict if they interpret language too literally
- reluctance to look at things in a different way
At times, inflexible thinking can benefit individuals with autism by enabling them to be goal-oriented and possess a strong work ethic.
However, rigid thinking associated with OCD is driven by the urgent need to perform rituals that prevent unwanted thoughts or protect against perceived harm. When an individual with OCD feels the compulsion to wash, check, count, or arrange items to prevent negative outcomes, they become inflexible in ensuring that they complete those rituals.
What if you’re autistic and you have OCD?
It is possible to have both OCD and autism, and some individuals may only be aware of one diagnosis.
Research has uncovered similarities in brain structure between the two conditions, with individuals with both OCD and autism showing increased gray matter in the caudate nuclei (CN) brain region. The CN is linked to restricted and repetitive behaviors.
Managing these conditions can be challenging because while many behaviors shared by individuals with OCD and autism appear similar, the underlying causes are distinct.
What treatments can help?
The aim of treating autism and OCD is to enhance an individual’s overall well-being. In cases where mild stimming or restricted interests are not distressing for someone with autism, no intervention may be necessary.
The appropriate treatment approach will depend on the underlying cause of the repetitive behavior. If the repetitive behavior is a result of autism stimming, an OCD-focused treatment approach may not be effective as autism stims are not driven by fear.
In cases where the behavior that appears to be stimming is actually OCD rituals, treatment can focus on addressing the fearful thoughts that trigger such rituals.
Treatment options include:
- social skills training to help the autistic person collaborate with a therapist
- anger management and mindfulness training to help with emotional regulation
- therapy to help reduce the OCD response to triggers
- to identify unhelpful thoughts and replace them with better ones
- medication such as
Treatment for both autism and OCD can help reduce the impact of their characteristics on daily life, as well as reduce anxiety and improve social interactions.
For autism, treatment often includes behavioral therapy, such as Applied Behavioral Analysis (ABA), social skills training, and speech therapy. Medication may also be used to treat co-occurring conditions such as anxiety or depression.
For OCD, treatment usually involves a combination of cognitive behavioral therapy (CBT) and medication. CBT helps people learn to manage their obsessive thoughts and compulsive behaviors by changing the way they think about them. Medications such as selective serotonin reuptake inhibitors (SSRIs) can also help reduce symptoms.
It’s important to note that treatment for both conditions is highly individualized and may involve a combination of approaches tailored to the specific needs of each person.
Caregivers can support treatment efforts. Some ways to do this include:
- maintaining scheduling consistency
- improving communication methods
- observing and remembering triggers
- using role playing exercises to practice trigger situations like transitions
- communicating the care plan to everyone involved
Equally important, caregivers can benefit from support to reduce any stress they may be feeling. Caregiving for someone with autism or OCD can be challenging and can take a toll on a caregiver’s emotional and physical well-being. Caregivers may benefit from support groups, therapy, or self-care activities to help them manage their stress and provide better care for their loved ones. It’s essential to prioritize caregiver well-being to ensure that they can continue to support their loved ones effectively.
Next steps
Autism and OCD are distinct conditions that can co-occur. They can have an impact on daily life, but with the right assistance, they can be managed effectively.
Various treatments are available to alleviate the impact of having both diagnoses. Your physician can assist you in creating a treatment strategy that minimizes anxiety and the disruption that behaviors like stimming can cause.
Obtaining an accurate diagnosis is critical, and you can collaborate with your physician to explore the diagnostic procedure.
