Throughout the duration of this course we have touched on many different topics and disorders that all have been truly unique and very interesting. However, the chapter I found the most interesting was Anxiety Disorders and particularly Post-Traumatic Stress Disorder (PTSD). Therefore, I will present a brief history of Post-Traumatic Stress Disorder such as, its origin and how this disorder has affected individuals over generations. I will be touching on all aspects of this disorder ranging from how this disorder can be acquired in many different ways, forms to its multiple effects on individuals, and how this affects their behaviors and life style. I will also discuss treatments and some specific examples of PTSD.
