Definition
Persistent thoughts, also known as obsessions, are recurring and uncontrollable thoughts or urges that cause distress or anxiety. These thoughts can be intrusive and difficult to ignore or dismiss.
Compulsions are repetitive behaviors or actions that people feel compelled to perform in response to their obsessions. For example, repeatedly washing hands in response to the obsessive thought of germs.
OCD is a mental disorder characterized by the presence of persistent obsessions and/or compulsions that significantly interfere with daily life. It often involves repetitive behaviors aimed at reducing anxiety caused by obsessions.
Intrusive thoughts are unwanted and distressing thoughts that pop into one's mind without invitation. They can be violent, inappropriate, or focused on taboo subjects, leading to significant distress for the individual.
