The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) debuted at the American Psychiatric Association (APA) annual meeting in May 2013. Since the publication of DSM-I in 1952, a standard review process has led to revised DSM editions over the past two decades. Advances in neurology, genetics, and behavioral science ...
Making the manual useful to clinicians diagnosing and treating people with mental disorders is the highest priority. In addition to changes noted above, the DSM-5 incorporated a dimensional assessment approach, allowing clinicians to measure both the presence and the severity of ASD symptoms as: “very severe,” “severe,” “moderate”, or “mild” in the...
The “disappearance” of Asperger’s Disorder has created a lot of confusion. According to researchers (Ghaziuddin, 2010; Kaland, 2011), DSM-IV-TR Asperger’s Disorder and Autism diagnostic criteria were vague and difficult to use. For example, ‘language delay’ was not operationally defined. Language deficits typically displayed by individuals with Asp...
With an estimated prevalence of 1 in 88 children, ASD is one of the most common neurodevelopmental disorders; however, the changes in DSM-5 diagnostic criteria may address a criticism of prior DSM editions that have been associated with increased prevalence rates (McPortland et al., 2012). Several studies have explored the proposed DSM-5 algorithm ...
- Four previously separate categories of autism consolidated into one umbrella diagnosis of “autism spectrum disorder.” The previous categories were: Autistic disorder.
- Consolidation of three previous categories of autism symptoms. Social impairment. Language/communication impairment and. Repetitive/restricted behaviors. into two categories of symptoms.
- The addition of sensory issues as a symptom under the restricted/repetitive behavior category. This includes hyper- or hypo-reactivity to stimuli (lights, sounds, tastes, touch, etc.)
- A severity assessment scale (levels 1-3) based on level of support needed for daily function.
The DSM-5 revised the symptoms that were required to make a diagnosis of ASD, combining the separate social and communication domains to a single social-communication domain and adding sensory symptoms as a diagnostic criterion.
