Obsessions and compulsions
Compulsive behaviour or obsessive thoughts are sometimes referred to as Obsessive-compulsive disorder (OCD). A distinction is made between recurrent and disturbing thoughts, or obsessions, and repetitive or ritualized behaviors, called compulsions. Compulsions can also take on the form of intrusive images or unwanted impulses.
The person with OCD usually tries to actively dismiss the disturbing thoughts or neutralize them by engaging in compulsive behaviors or avoiding situations that trigger them. In most cases, compulsions relieve anxiety. The compulsions however, can also lead to anxiety, especially when they become very demanding.|
Examples of obsessions are fear of contamination, accidents or disasters. Examples of compulsions are constantly washing hands, counting, checking doors, etc.
This behaviour can significantly interfere with normal life, making it incredibly difficult to ignore.
