Compare and contrast panic disorder with obsessive-compulsive disorder (OCD) with regard to symptoms, heritability, and brain activation
What will be an ideal response?
Answer: Panic attack involves episodes of intense anxiety such that the person is incapacitated by the attack. OCD involves persistent uncontrollable thoughts and uncontrollable motor behaviors (compulsions). Each disorder is highly heritable, as evidenced by a high concordance value for identical twins relative to fraternal twins. Panic attacks result in reduced activation of the frontal cortex, whereas OCD is associated with an increased activity of the frontal cortex and caudate nucleus.
