Autism
About Autism
Autism is a neurodevelopmental condition characterized by differences in social communication, sensory processing, and patterns of behavior, interests, or routines. Individuals with autism may experience differences in communication style, sensory responsiveness, flexibility, or behavioral patterns across settings.
Autism exists on a spectrum, meaning presentations and support needs can vary significantly between individuals.
Comorbidity with OCD
Obsessive-compulsive disorder (OCD) and autism, while distinct, share features such as repetitive behaviors, preference for sameness, and elevated anxiety.
In OCD, behaviors are typically performed in response to intrusive, distressing thoughts (obsessions) and are aimed at reducing anxiety via physical and mental behaviors called compulsions.
In autism, repetitive behaviors or routines (referred to as “restrictive and repetitive behaviors” or “stimming”) are often self-regulating, comforting, or rooted in sensory processing, rather than fear-based obsessions. These behaviors are often experienced as positive or neutral, not unwanted.
Repetitive Behaviors in Autism
May include:
- Repetitive movements (hand-flapping, rocking)
- Repeating words or phrases
- Strong preferences for routines or sameness
- Deep focus on specific interests
- Lining up toys or objects in a particular way
Repetitive Behaviors in OCD
May include:
- Repeatedly checking locks or appliances
- Handwashing or cleaning rituals
- Counting, tapping, blinking, or repeating actions “until it feels right”
- Seeking repeated reassurance
- Mental rituals such as repeated prayers or phrases
