Adjustment Disorder vs PTSD: Understanding the Differences

Reading Time: 2 minutes

When it comes to mental health disorders, understanding the nuances between different conditions can often be a complex task. Adjustment disorder and posttraumatic stress disorder (PTSD) are two such conditions that are frequently confused. 

What is adjustment disorder?

Adjustment disorder is a mental health condition that occurs when an individual struggles to cope with a stressful event or major life change. These stressors can include events such as a breakup, loss of a job, or moving to a new place.


The symptoms of adjustment disorder can vary widely, but typically include feelings of sadness, anxiety, and trouble sleeping. Unlike other mental health conditions, the symptoms are directly linked to a specific event and usually begin within three months of the stressor.


Treatment for adjustment disorder often includes therapy that focuses on coping strategies. The symptoms tend to subside once the individual has adapted to the change or stressor, and the disorder rarely lasts more than six months.

What is PTSD?

Posttraumatic stress disorder is a mental health condition triggered by experiencing or witnessing a terrifying event. It’s much more severe than adjustment disorder and can have long-lasting effects.


PTSD symptoms are more profound and enduring. They may include flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the event. These symptoms can severely affect an individual’s daily life.


PTSD often requires a more intensive treatment approach, including therapy and medication. Treatment might include cognitive behavioural therapy (CBT) or eye movement desensitisation and reprocessing (EMDR), to help the individual process the trauma.

Key differences

  • Cause. While both disorders are triggered by stressful events, adjustment disorder is often linked to life changes or transitions, while PTSD is linked to traumatic experiences that threaten life or safety.
  • Severity. PTSD is typically more severe, with symptoms that can interfere substantially with daily life.
  • Duration. Adjustment disorder is usually short-term, often resolving within six months, while PTSD can continue for years, or even a lifetime.
  • Treatment. The treatment approaches differ in intensity, with PTSD often requiring a more involved therapeutic process.


Despite their differences, these two disorders also share similarities:

  • Both involve a reaction to a stressor.
  • Both can affect anyone, regardless of age or background.
  • Treatment for both typically involves therapy, though the approaches and intensity may differ.


The understanding of adjustment disorder and PTSD is essential for appropriate diagnosis, treatment, and support. While both stem from stressful events, they vary significantly in their causes, severity, duration, and treatment. Adjustment disorder is a short-term response to a life change, while PTSD is a more profound and lasting reaction to a traumatic event.

The best course of action for anyone experiencing symptoms of either disorder is to seek professional help. With appropriate care, recovery is not just possible; it’s probable.
