Which of the following is NOT a common anxiety disorder?

Schizophrenia is categorized as a psychotic disorder rather than an anxiety disorder. It is characterized by symptoms such as delusions, hallucinations, and disorganized thinking, which significantly impact an individual's perception of reality. This distinguishes it from anxiety disorders, which primarily involve excessive fear or worry that interferes with daily functioning.

In contrast, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder are all classified within the anxiety disorders domain. Panic disorder involves recurrent panic attacks, while generalized anxiety disorder is characterized by persistent and excessive worry about various aspects of life. Obsessive-compulsive disorder includes unwanted recurrent thoughts (obsessions) and repetitive behaviors (compulsions) driven by those thoughts. Each of these disorders shares the common feature of anxiety being a central component, making schizophrenia the only option that does not fit within the anxiety disorders category.
