In the early 20th century, the primary purpose for mental disorder classification was to organize asylums.{[1]  The process for categorizing symptoms lacked standardization and thus was inconsistent. Even so, the categories were preserved so psychiatrists could collect statistics for public policy and funding. After time progressed and techniques became more sophisticated, the American Psychiatric Association created the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1952. Serving as a guide to diagnosis, the primary purpose of the DSM was to standardize the classification of mental disorders. The first edition of the DSM contained nearly 100 disorders that were characterized by behavioral symptoms. Over the past 60 years, the DSM has been the standard for diagnosing mental disorders.  [1]  Although the most recent edition of the DSM, the DSM-V, has improved specificity and consistency in its criteria, it still holds the potential for inaccurate diagnosis.  [2, 3]  With the exception of drug dependency, the DSM predominantly considers emotional and behavioral symptoms rather than biological symptoms.  [4]
