EXAM II SAMPLE ESSAY: Disorder: PTSD: A. Description: Posttraumatic Stress Disorder is defined by symptoms of re-experiencing, avoidance, and arousal, but the symptoms either are longer lasting or have a delayed onset. It is triggered by exposure to a traumatic stressor. Symptoms must last more than one month. B1. Closely Related Disorder Acute Stress Disorder B2. How is this disorder similar to but different from your chosen disorder? Similar: both characterized by re-experience trauma, marked avoidance of stimuli associated with trauma, and persistent arousal or increased anxiety Different: ASD is also characterized by dissociative symptoms because they occur in the immediate aftermath of a trauma, lasting no longer than 4 weeks C. 3 kinds of supporting evidence: 1. MZ twins have higher concordance rate than DZ twins for developing symptoms of PTSD after experiencing trauma 2. Cognitive factors like preparedness and control influence risk of PTSD 3. People with PTSD have higher levels of norepinephrine D. Two Kinds of Contradictory Evidence 1. PTSD is highly comorbid with depression 2. Correlation is not equal to causation—we don’t know whether hormone changes cause or are caused by the disorder (or medication) E. Summary Evaluation PTSD makes sense given the evidence that supports it. However, because of comorbidity with depression and dissociation and the overall similarity with ASD, as currently defined, it may be defined a bit too narrowly and need to be broadened - 1 -

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
