Attention-deficit/hyperactivity disorder (ADHD) in girls is frequently misunderstood because it does not always present through overt hyperactivity or disruptive behavior. Instead, many girls experience ADHD as dysregulated affective intensity—rapid mood shifts, rejection sensitivity, shame reactivity, and chronic self-criticism. When ADHD is evaluated through a predominantly male behavioral framework, these internalized symptoms are often misattributed to anxiety, depression, or trauma-related disorders.

Distinguishing ADHD-related emotional dysregulation from trauma-based reactivity is clinically essential. Although both may involve irritability, concentration difficulties, and heightened arousal, ADHD reflects a neurodevelopmental regulatory vulnerability, whereas posttraumatic stress disorder (PTSD) is organized around conditioned fear responses and trauma cues. Without careful developmental assessment, treatment may address only part of the clinical picture.

A formulation that integrates neurodevelopmental history, relational context, and trauma exposure allows for more accurate diagnosis and more precisely targeted intervention.

Rejection Sensitive Dysphoria (RSD) is commonly described as an intense emotional reaction to perceived criticism, disapproval, or exclusion. However, for individuals with ADHD, this response is neither exaggerated nor disproportionate; it reflects a neurobiological event directly linked to belonging, identity formation, and perceived relational security.
