When an individual has significant difficulty in forming healthy emotional relationships, often following abuse. Individual might struggle with affect regulation, engage in aggressive/disruptive behavior, be socially withdrawn, and have an aversion to touch/physical affection. 

Reactive Attachment Disorder (RAD)

This disorder is diagnosed among children older than nine months, who willingly approach and engage with adults they don’t know. This is due to inadequate care, limiting the child’s opportunity to form a stable bond with a main caregiver.

Disinhibited Social Engagement Disorder

Acute stress disorder is a kind of trauma and stress related disorder. It is a mental health disorder which occurs within the first month (3 days to 1 month following exposure) of experiencing trauma, or one or more traumatic events. However, once the symptoms occur longer than one month, acute stress disorder becomes post traumatic stress disorder.

Acute Stress Disorder

Prolonged grief disorder occurs when a person experiences grief that persists longer and is more intense than typical grief. The grief can become severe enough to interfere with the person's day-to-day life, often affecting work, home, friendships and other important areas of life. 

Prolonged Grief Disorder

The DSM-5-TR separates Trauma-and Stressor-Related Disorders into the following specific disorders:
- Reactive Attachment Disorder
- Disinhibited Social Engagement Disorder
- Posttraumatic Stress Disorder (PTSD)
- Acute Stress Disorder
- Adjustment Disorders
- Prolonged Grief Disorder
- Other Specified Trauma- and Stressor-Related Disorder
- Unspecified Trauma- and Stressor-Related Disorder


Trauma- and Stressor-Related Disorders are characterized by exposure to a traumatic or stressful event. Symptoms and reactions vary for each case and while they may be understood in an anxiety- or fear-based context, individuals often instead prominently display anhedonic, dysphoric, dissociative, and/or aggressive symptoms. This variability in the display of symptoms imposes a distinction from other similar disorders, which then also requires that for one to be diagnosed with a trauma- and stressor-disorder, they specifically must have had explicit exposure to a traumatic or stressful event.
