Final answer:
The 2013 update of the DSM-V introduced new categories, revised existing criteria, and removed certain diagnoses like Asperger's syndrome, reclassifying it under autism spectrum disorders, and modified the approach to diagnosing substance use disorders.
Step-by-step explanation:
The update to the Diagnostic & Statistical Manual V (DSM-V) in May 2013 included several changes, such as the creation of new categories of mental disorders, modification of existing criteria, and removal of certain diagnoses. For example, the DSM-5 reclassified Asperger's syndrome under the broader category of autism spectrum disorder and introduced a dimensional approach to diagnosing disorders, where the severity of symptoms is also considered. Additionally, it revised the way substance use disorders are diagnosed, integrating the previous distinctions between abuse and dependence into a single spectrum with varying degrees of severity.
