Obsessive-Compulsive Disorder

A person with obsessive-compulsive disorder (OCD) is caught in a cycle: an intrusive thought, image, or urge produces distress; a ritual or repeated mental act briefly lowers that distress; the temporary relief teaches the brain to repeat the ritual the next time the thought appears. The ritual may be visible, such as washing or checking, or entirely covert, such as counting, praying, reviewing a memory, or seeking certainty. The clinical problem is not an unusual thought by itself. It is the combination of unwanted intrusions, ritualized responses, and the time, distress, or impairment they create. Nursing assessment therefore focuses on the function of the behaviour, the person’s ability to care for basic needs, and whether staff or family are unintentionally reinforcing the cycle.
