DSM-5 New Disorder Introductions

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), introduced several new diagnoses and revised existing ones. We need to identify which disorders from the list were newly added in this edition.

Disorder Analysis

• Premenstrual Dysphoric Disorder (PMDD): This disorder was officially added to the DSM-5, moving from the appendix of DSM-IV where it was listed for further study.
• Mild Neurocognitive Disorder (MNDC): The DSM-5 introduced Mild Neurocognitive Disorder to replace the term "mild cognitive impairment." It describes a less severe level of cognitive decline.
• Disruptive Mood Dysregulation Disorder (DMDD): This diagnosis was added in DSM-5, primarily aimed at diagnosing children with persistent irritability and frequent temper outbursts, distinguishing it from childhood-onset Bipolar Disorder.
• Road Rage Behaviour Disorder: This is not a recognized diagnosis in the DSM-5. While aggression or anger issues can be symptoms of various disorders, "Road Rage Behaviour Disorder" is not a formal classification.

Conclusion on DSM-5 Additions

Based on the analysis, Premenstrual Dysphoric Disorder (a), Mild Neurocognitive Disorder (b), and Disruptive Mood Dysregulation Disorder (c) are disorders newly introduced or significantly revised and classified in DSM-5. Road Rage Behaviour Disorder (d) is not a DSM-5 diagnosis.

Therefore, statements (a), (b), and (c) are correct, and (d) is incorrect.
