What mental disorder is characterized by repetitive actions like excessive handwashing?

Obsessive Compulsive Disorder (OCD) is indeed characterized by repetitive actions, often referred to as compulsions, that individuals feel driven to perform in response to certain obsessions or fears. In the case of excessive handwashing, this behavior may stem from an individual's intense anxiety about contamination or a preoccupation with cleanliness. People with OCD may engage in such rituals as a way to manage their anxiety, despite recognizing that these actions may be excessive or irrational.

This condition is distinct from other disorders included in the options. For instance, Attention Deficit Hyperactivity Disorder (ADHD) typically involves issues with attention, hyperactivity, and impulsivity, rather than repetitive behaviors. Generalized Anxiety Disorder (GAD) is characterized by pervasive and excessive worry about various aspects of life, but it does not specifically involve the compulsive repetitive actions associated with OCD. Major Depressive Disorder focuses on pervasive low mood, loss of interest, and various physical symptoms, rather than the specific behavioral patterns seen in OCD.

By understanding the specific characteristics of OCD, one can see how excessive handwashing fits within the framework of the disorder, reinforcing the notion that OCD is rooted in the cycle of obsessions and compulsive behaviors aimed at reducing anxiety.
