What are the symptoms of obsessive-compulsive disorder (OCD)? What evidence of a brain abnormality has been found to explain some cases of OCD?
What will be an ideal response?
Answer: A good answer will include the following key points.
? The most common compulsions are hand washing, counting, touching, and checking.
? Obsessive thoughts take many forms, but they are alike in reflecting impaired ways of reasoning and processing information.
? OCD suffers usually realize that their behavior is senseless, and they are often tormented by their rituals.
? In many people with OCD, abnormalities in an area in the prefrontal cortex may result in cognitive rigidity, an inability to let go of intrusive thoughts, and behavioral rigidity, an inability to alter compulsive behavior after getting negative feedback.
? In people with OCD, the brain's alarm signal fails to shut off the alarm when danger is past; the sufferer feels in a constant state of danger.
