When compulsions dominate daily life.
The symptoms consist of an inner compulsion to perform or think certain things. With compulsive actions, these may be compulsions to wash or check, or compulsions to carry out certain (ordering) rituals in a specific sequence or with a specific frequency. With obsessive thoughts, there are usually threatening ideas — for example, fear of becoming contaminated (through germs on objects), which subsequently (in 75 % of those affected) leads to corresponding compulsive actions (cleaning door handles). However, obsessive thoughts can also involve ideas of an aggressive nature, or a ritualised circular thinking that is supposed to prevent something bad from happening. In any case, those affected are aware that their compulsions impose themselves with an irresistible inner force but are fundamentally rather distorted and 'absurd.' This distinguishes compulsions from delusions, in which there is no inner critical distance from the symptom. Considerable distress arises when daily life is so severely affected that carrying out the compulsions causes a permanent lack of time and professional and private obligations can no longer be met. Compulsive collecting (and the 'inability to let go') of objects up to the level of hoarding disorder can also be understood as a subtype of obsessive-compulsive conditions.
