My wife has severe OCD. She has gotten to the point she has basically 0 symptoms now. Where before she couldn't drive or leave the house. Here is what I've learned through our journey.
The repetitive actions are often caused by intrusive thoughts. My wife's stemmed from actions that were tied to her morality, and her memory. Such as, she would drive around the block 5 times because she would have this thought, "What if you ran over a kid but you don't remember it?" Which was the worse thing she could have done.
90% percent of people with OCD are also neurodivergent, namely autistic. My wife wasn't diagnosed with Autism until after her OCD diagnosis.
