Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop after extremely distressing or life-threatening events. These may include accidents, experiences of violence, abuse, war-related events, or natural disasters.

Not every distressing event leads to PTSD. However, if symptoms persist for weeks or months and significantly impair daily functioning, a condition requiring treatment may develop.

A typical feature is the repeated, involuntary re-experiencing of the traumatic event, accompanied by intense inner tension and avoidance behavior.

Symptoms

Symptoms can be divided into four main categories:

Re-experiencing (Intrusions):

  • Flashbacks

  • Nightmares

  • Distressing memories

  • Intense emotional or physical reactions to triggers

Avoidance:

  • Avoiding certain places or situations

  • Suppressing distressing thoughts

  • Social withdrawal

Negative changes in thinking and mood:

  • Feelings of guilt or shame

  • Emotional numbness

  • Persistent negative beliefs

  • Loss of interest

Hyperarousal:

  • Sleep disturbances

  • Irritability

  • Concentration difficulties

  • Heightened startle response

Symptoms may occur immediately after the event or develop with a delay.

Types

  • Acute stress reaction (short-term reaction immediately after trauma)

  • Post-Traumatic Stress Disorder (PTSD)

  • Complex PTSD (following prolonged or repeated traumatization)

Accurate classification is essential for treatment planning.

Causes

PTSD develops as a result of a traumatic event in combination with individual risk factors:

  • Type, duration, and intensity of the trauma

  • Lack of social support

  • Previous traumatic experiences

  • Individual stress processing

On a neurobiological level, changes occur in the systems regulating stress and anxiety.
