Intrusive Thoughts and Autism

If you've ever experienced sudden, unwanted thoughts that seem to have come out of nowhere, you're not alone. Intrusive thoughts can happen to anyone - but for people with autism, they can sometimes feel more intense, confusing, and harder to manage.

Understanding how intrusive thoughts interact with autism can help reduce distress and build healthier, manageable ways of coping.

What are intrusive thoughts?

‍

Intrusive thoughts are unwanted, involuntary thoughts, images, or urges that enter your mind suddenly, they often make an appearance without warning, and often feel distressing because they don’t match who you are or what you believe.

Some examples of what they are can be; thoughts about harm to yourself or others, sudden fears about losing control, repetitive mental images, or ‘what if’ style scenarios.

It’s important to remember that having an intrusive thought does not mean you will act on it.

How intrusive thoughts can feel to someone with autism

‍

For autistic individuals, the distinction between a thought and an intent can sometimes be harder to grasp without support, especially if there’s a tendency toward logical interpretation. Autistic people may process information differently (emotions, and sensory). Several factors can make these thoughts feel more intense:

• Difficulty filtering thoughts - finding it harder to dismiss a thought that isn’t relevant. 
• Literal thinking styles - if someone prefers clearer interpretations, an intrusive thought may lead to confusion, or anxiety about what the thought means.
• Heightened anxiety and sensory overload - when someone is overwhelmed (emotionally or sensorially), intrusive thoughts may appear more often and feel more distressing. 
• Repetitive thinking patterns - this can potentially lead to fixation on specific ideas, replaying conversations, and mental ‘loops’, making it hard to ‘switch off’.

Coping strategies for intrusive thoughts

‍

While it can be difficult to predict when unwanted thoughts may appear, there are methods that you can use to help support you through uncomfortable thoughts and feelings: 

1. Call it out as it is - label the thought ‘that is an intrusive thought’ which helps to create distance and reduce emotional impact.
2. Avoid over analysing it - individuals often argue with the thought or look for reason behind it, instead think of it as mental noise without meaning. 
3. Use grounding techniques - a fab technique is to bring your attention to the present moment: 

• notice five things you can see
• focus on your breathing, or 
• engage with a sensory object like a fidget toy to distract your mind. 

All of these techniques can help interrupt the repetitive thinking cycles. 

4. Using healthy distractions - replace or interrupt those unwanted thoughts with a healthy distraction. A micro-hit of dopamine, like seeing a friend, or sharing a funny link, or photo can be a powerful tool to pull your attention away from the anxious thought loop.
5. Keeping to a structured routine can help reduce overall stress, making unwanted thoughts less frequent or intense.

When intrusive thoughts feel like too much

If intrusive thoughts are:

• happening frequently
• causing significant anxiety
• affecting your daily life

…it’s important to seek support. You do not need to handle them alone.

Talking to a GP, therapist, or support service can make a big difference, especially when the approach is neurodiversity-informed.

If intrusive thoughts are persistent or distressing, Cognitive Behavioural Therapy (CBT) can be highly effective. CBT can help you to change how you relate to thoughts, rather than eliminate them.

Intrusive thoughts can feel unsettling, especially when combined with the unique ways autistic people experience the world. But they are common, manageable, and not a reflection of your character and who you are.
