Understanding Attachment Disorders
A clear guide to two childhood diagnoses: reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED).

Start here: Attachment disorders are not the same as anxious, avoidant, or disorganized attachment styles. They are specific childhood conditions associated with a history of severely insufficient caregiving.
I want to understand clinical attachment disordersLearn about RAD and DSED and compare their features.
What Are Attachment Disorders?
Children develop attachment through repeated experiences of safety, comfort, and responsive caregiving. When a young child has experienced severe neglect, repeated changes in primary caregivers, or other circumstances that greatly limit opportunities to form stable attachments, development can be affected.
RAD and DSED are two different disorders associated with this type of early caregiving disruption. They are not simply labels for difficult behavior or relationship insecurity. Many children who experience adversity do not develop either disorder.
Understanding RAD & DSED
Select a disorder to see its main features and an everyday example. The explanation changes here without opening another page.
Reactive Attachment Disorder (RAD)
RAD involves an emotionally withdrawn pattern toward familiar caregivers. A young child may rarely seek comfort when distressed and respond only minimally when comfort is offered. Limited positive emotion or episodes of unexplained fear, sadness, or irritability during caregiver interactions may also occur.
Emotional distance or independence alone does not establish RAD. Clinicians consider the child's developmental history and the full diagnostic criteria.
Disinhibited Social Engagement Disorder (DSED)
DSED involves unusually familiar, socially disinhibited behavior with unfamiliar adults. A child may approach strangers without age-appropriate hesitation, show overly familiar behavior, or wander away without checking back with a caregiver.
Being outgoing or friendly does not by itself indicate DSED. The behavior must be considered in the context of development and severely insufficient early care.
I want to understand how they differ from other patternsSee how clinical disorders differ from attachment styles and other experiences.
What Attachment Disorders Are Not
Some behaviors can look similar across conditions, but the reasons behind them may be different.
Attachment styles
Anxious, avoidant, secure, and fearful-avoidant patterns are not RAD or DSED diagnoses.
Autism or ADHD
Social communication differences or impulsivity may affect relationships and boundaries, but they do not establish an attachment disorder.
Trauma responses
Withdrawal, fear, or emotional dysregulation after trauma can occur without meeting criteria for RAD or DSED.
Borderline Personality Disorder (BPD)
BPD is a separate psychiatric diagnosis involving broader patterns of emotional, identity, and interpersonal difficulties. It is not an attachment disorder, and insecure attachment or childhood trauma alone does not establish BPD.

Diagnosis, Treatment & Support
Diagnosis: A qualified child mental health clinician considers developmental and caregiving history, the child's behavior across settings, and other possible explanations. There is no single online questionnaire that can diagnose RAD or DSED.
Treatment: Support centers on safe, stable, responsive caregiving, developmentally appropriate child and family interventions, and addressing any co-occurring developmental or trauma-related needs.
What caregivers can do
Offer predictable routines, respond consistently to distress, respect physical boundaries, and build trust through repeated safe interactions.
When to seek an evaluation
Speak with a pediatrician or child mental health specialist if a young child shows persistent concerns about seeking comfort, responding to caregivers, or interacting safely with unfamiliar adults.
