Post-traumatic stress disorder (PTSD) is a psychiatric condition that individuals may develop after experiencing or witnessing a traumatic event that is emotionally or physically harmful or poses a threat to their life.

Even if a person does not meet the diagnostic criteria for PTSD, divorce can be a traumatic event that causes similar symptoms. Only a healthcare professional can diagnose and treat someone for PTSD and other potential mental health concerns.

A 2018 case study describes divorce as one of the most traumatic events a person can experience.

While divorce and relationship breakups may not pose a threat to life, some researchers refer to these events as “small-t traumas” and suggest they can cause symptoms associated with PTSD, such as recurrent negative thoughts and avoidance behaviors.

A more recent 2023 study highlights significant associations between a breakup with a romantic partner and post-traumatic stress symptoms. These symptoms may be similar to those of PTSD.

A 2018 review suggests these symptoms could indicate a condition called post-traumatic stress syndrome (PTSS). PTSS has similar symptoms to PTSD, but they occur within a month of experiencing a traumatic event. PTSS can be a precursor to PTSD.

Research on PTSD after divorce is limited. One older 2017 study of 120 Kazakh divorcees found that 21% of people met the criteria for partial-PTSD and 26% met the criteria for full PTSD.

An older 2015 study of recent divorce among U.S. military service members suggests that a positive PTSD diagnosis was significantly more likely within a 3-year period among divorcees.

However, the researchers highlight the challenges of finding a link between PTSD and divorce, since PTSD can take variable lengths of time to develop.

The dissolution of a romantic relationship can trigger PTSD symptoms. However, these may not meet the diagnostic criteria in the Diagnostic and Statistical Manual, 5th Edition (DSM-5).

Research also highlights links between intimate partner violence and PTSD, suggesting a person may be more likely to experience PTSD following divorce if the relationship was abusive.

PTSD is a psychiatric disorder that may develop after experiencing or witnessing an event involving a perceived or real threat to life or physical integrity and safety. This, in turn, causes fear, terror, or helplessness.

The symptoms of PTSD must also continue for more than a month, cause significant distress or functional impairment, and not be due to medication, substance use, or illness.

Anyone experiencing mental health difficulties following a divorce can speak with a healthcare professional to understand what resources and help are available. In some cases, a doctor may be able to provide treatment.

The United Kingdom’s National Health Service (NHS) advises people to see a doctor if they continue to experience PTSD symptoms 4 weeks after a traumatic experience, or if the symptoms significantly interfere with their daily functioning.

A doctor can refer a person to a mental health specialist for a diagnosis and appropriate treatment.

The following organizations may be able to help people experiencing mental health difficulties following a divorce:

People can develop PTSD after experiencing or witnessing a traumatic life event, or a series of traumatic life events that pose a threat to their life or safety. Symptoms include flashbacks, nightmares, and avoidance of reminders associated with the traumatic event.

Divorce can be a traumatic life event. For some people, it may cause symptoms associated with PTSD, even if someone does not fit the criteria for an official diagnosis.

People can speak with a doctor for treatment and support if they experience PTSD symptoms that significantly affect their daily functioning after a divorce. A healthcare professional can also direct someone to support resources.
