Causes and Why It Happens
- Stress or heightened anxiety
- A strong sensitivity to uncertainty or threat
- OCD-related fear of what a thought might mean
- Thought suppression that makes the thought more noticeable
Many intrusive thoughts become more distressing when the brain starts treating them like problems that must be solved, prevented, or neutralized. The more a person checks, avoids, or argues with the thought, the more attention it tends to receive.
Treatment
Treatment usually focuses on changing the response to the thought rather than proving the thought is impossible. ERP, CBT-informed work, and ACT-informed skills can help reduce compulsive responding and build tolerance for uncertainty.What It Is
