Definition
OCD involves unwanted, distressing intrusive thoughts (obsessions) and repetitive actions or mental rituals (compulsions) done to relieve the anxiety they cause. It commonly co-occurs with autism and can be easy to miss behind autistic traits.
Why It Matters
Distinguishing OCD from autistic routines and special interests matters, because OCD compulsions are distressing and unwanted, while interests and routines are usually valued and comforting. Getting the distinction right shapes the right support.
Common Misconception
OCD is not being tidy or liking order. It is driven by distressing intrusive thoughts and anxiety, and the compulsions bring relief, not enjoyment, which is what sets it apart from a special interest or a preferred routine.
