AP PSYCHOLOGY

Detailed explanation-1: -People with GAD tend to jump from one anxiety to another throughout their day (or have a general sense of being overwhelmed), whereas someone with OCD is more likely to obsess on a particular anxiety (or a few of them) and devote excessive attention to it.

Detailed explanation-2: -While anxiety disorders are typically characterized by excessive worry, OCD is marked by unwanted thoughts that lead to compulsive mental or physical reactions. A person with an anxiety disorder will experience excessive worry, but not engage in compulsive behavior to reduce their anxiety.

Detailed explanation-3: -Obsessive-compulsive disorder (included in the obsessive-compulsive and related disorders), acute stress disorder, and posttraumatic stress disorder (included in the trauma and stress-related disorders) are no longer considered anxiety disorders as they were in the previous version of the DSM.

Detailed explanation-4: -Neuroimaging research that implicates the prefrontal striatal cortex as an important location for executive functioning in the brain, supports the theory that malfunctioning in this brain area causes OCD. The moral of the story is that OCD is no longer categorized as an anxiety disorder in the DSM.
