Emotional dysregulation in the context of "Attention deficit hyperactivity disorder"

Borderline personality disorder (BPD) is a personality disorder characterized by a pervasive, long-term pattern of significant interpersonal relationship instability, acute fear of abandonment, and intense emotional outbursts. People with BPD frequently exhibit self-harming behaviours and engage in risky activities, primarily caused by difficulties in regulating emotions. Symptoms such as dissociation, a pervasive sense of emptiness, and distorted sense of self are prevalent.

Onset of symptoms can be triggered by events others perceive as normal, with the disorder typically manifesting in early adulthood and persisting across diverse contexts. BPD is often comorbid with substance use disorders, depressive disorders, and eating disorders. Studies estimate up to 10 percent of people with BPD die by suicide. BPD faces significant stigmatization in media portrayals and the psychiatric field, leading to underdiagnosis and insufficient treatment.

Complex post-traumatic stress disorder (CPTSD, cPTSD, or hyphenated C-PTSD) is a stress-related mental disorder generally occurring in response to complex traumas (i.e., commonly prolonged or repetitive exposure to a traumatic event (or traumatic events), from which one sees little or no chance to escape.)

In the ICD-11 classification, C-PTSD is a category of post-traumatic stress disorder (PTSD) with three additional clusters of significant symptoms: emotional dysregulation, negative self-beliefs (e.g., shame, guilt, failure for wrong reasons), and interpersonal difficulties. C-PTSD's symptoms include prolonged feelings of terror, worthlessness, helplessness, distortions in identity or sense of self, and hypervigilance. Although early descriptions of C-PTSD specified the type of trauma (i.e., prolonged, repetitive), in the ICD-11 there is no requirement of a specific trauma type.
