Aggressive Obsessions. People with OCD often worry that they will cause harm by impulsively hurting someone just because they can. People with these thoughts typically have no history of violence, nor do they act on their urges or impulses.any people with obsessive-compulsive disorder (OCD) have sexual obsessions, or unwanted sexual thoughts.
Researchers have yet to pinpoint the exact cause of obsessive-compulsive disorder , but brain abnormalities, genetic (family) influences, and environmental factors are being studied. Brain scans of people with OCD have shown that they have different patterns of brain activity than people without OCD and that abnormal functioning of circuitry within a certain part of the brain (striatum) may cause the disorder.
