Prior to DSM-5, some researchers used lower symptom thresholds to define adolescent and/or adult ADHD samples (e.g., ), in discord with DSM-IV many clinicians did likewise or relied on the poorly-defined ADHD Not Otherwise Specified. In particular, it has become increasingly evident that the DSM-IV symptom domain thresholds (i.e., 6 of 9 symptoms per symptom domain), while appropriate for young children, are not effective for identifying adolescents and adults experiencing ADHD-related impairment. By retaining a similar ADHD phenotype as defined in DSM-IV, the DSM-5 workgroup ensured that the voluminous body of DSM-IV defined ADHD research accumulated over the past 2 decades will largely generalize to the new, yet highly similar, DSM-5 ADHD phenotype.Īlthough more subtle than changes in prior DSMs, the changes to ADHD in DSM-5 are important and reflect our increased knowledge about the nature of ADHD.
Moreover, individuals identified by DSM-IV ADHD criteria appear to have distinct neuropsychological profiles identifiable neurobiological signatures (e.g., abnormalities in frontal-striatal circuitry ) and unique genetic correlates. DSM-IV ADHD criteria have proven to be quite effective at reliably identifying a population of individuals who have significant impairments across a wide range of outcomes (e.g., academic, interpersonal, occupational, personal, substance use, driving, etc. The retention of the ADHD symptom domains and 18 core symptoms likely reflects a judgment that the DSM-IV definition of ADHD has largely withstood the test of time. Importantly, the DSM-5 ADHD and Disruptive Behavior Disorders Workgroup decided neither to modify the core ADHD symptom domains (i.e., Inattention and Hyperactivity/Impulsivity) nor to revise the 18 core symptoms, aside from adding example behaviors to better define some of the symptoms for older adolescents and adults. Overall, the revisions to ADHD in DSM-5 are less dramatic than updates to earlier DSMs.
DSM 5 ADHD CRITERIA FULL
Regarding nosology, the DSM-IV ADHD “types” are now referred to as “presentations.” Finally, modifiers were added so that the severity of the disorder (i.e., mild, moderate, or severe) can be specified and the disorder can be coded as “in partial remission” if full diagnostic criteria are not currently met. Criterion D (impairment) now requires that functional impairments only need to “ reduce the quality of social, academic or occupational functioning” instead of requiring that they be “clinically significant.” Criterion E (exclusionary conditions) no longer includes Autism Spectrum Disorder as an exclusionary diagnosis. Criterion C (pervasiveness) was changed from evidence of impairment to evidence of symptoms in two or more settings. Criterion B (age of onset) changed from onset of symptoms and impairments before age 7 to onset of symptoms before age 12. Criterion A (ADHD symptoms) are unchanged from DSM-IV except for additional examples of how symptoms may manifest in adolescence and adulthood, and a reduction from six to five in the minimum number of symptoms in either symptom domain required for older adolescents and adults. The DSM-5 revisions include modifications to each of the ADHD diagnostic criteria (A-E), a terminological change in the ADHD subtype nosology, and the addition of two ADHD modifiers.
DSM 5 ADHD CRITERIA UPDATE
The recent release of DSM-5 is the latest update to ADHD nosology. With the publication of the DSM- IV, the term ADHD was retained along with the introduction of three specific subtypes (predominantly Inattentive, predominantly Hyperactive-Impulsive, and Combined), defined by the presence of excessive symptoms of inattention and/or hyperactivity-impulsivity. The term Attention Deficit/Hyperactivity Disorder (ADHD) was introduced in DSM-III-R, with the controversial elimination of ADD without Hyperactivity.
With the publication of the DSM-III in 1980, the disorder was markedly re-conceptualized with a focus on problems with attention, impulsivity and hyperactivity, and was renamed Attention Deficit Disorder (with and without Hyperactivity). In DSM-II, the disorder was termed Hyperkinetic Reaction of Childhood, which as the name implies focused primarily on symptoms of excessive motor activity.
DSM 5 ADHD CRITERIA MANUAL
While there were earlier descriptions of children with high levels of activity and impulsivity, what is now called Attention-Deficit/Hyperactivity Disorder (ADHD) first appeared in the second edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders in 1968.
