Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after someone experiences or witnesses a traumatic event. However, not everyone exposed to trauma ends up with PTSD. Some people come out seemingly unscathed, some struggle a little, and others struggle a lot. So, what makes the difference? The answer involves a blend of psychological, biological and environmental factors that uniquely affect each person.
Understanding trauma and PTSD
“Trauma” can mean a wide range of intense, distressing experiences — from natural disasters and accidents to violence and life-threatening situations. For many, these experiences are difficult (and traumatic), but they don’t necessarily lead to PTSD. However, for those who do develop it, therapy for Post-Traumatic Stress Disorder can help manage the emotional and mental challenges that follow traumatic events. So, why do some people develop PTSD while others do not? Let’s look at some of the key factors involved.
Individual resilience and coping skills
Resilience plays a crucial role in how individuals respond to trauma. Healthy emotionalregulation, using such skills as cognitive reappraisal and relaxation strategies, help reduce PTSD risk by allowing individuals to process stress more adaptively. Active coping strategies — like problem-solving and seeking social support — are linked to increased resilience and lower PTSD risk. In contrast, passive or avoidance-based coping (e.g. ignoring the problem) can exacerbate symptoms and stress reactivity.
Pre-existing mental health conditions
People with pre-existing mental health conditions, such as anxiety or depression, are generally at a higher risk of developing PTSD. If someone is already managing mental health challenges, they may have a harder time processing trauma, making them more vulnerable. Mental health professionals may incorporate PTSD treatment alongside ongoing therapy for other mood disorders to ensure comprehensive support.
Genetic and biological factors
There’s some evidence to suggest that genetics can influence a person’s likelihood of developing PTSD. Certain individuals may have a genetic predisposition that makes them more sensitive to trauma. Biological factors, such as a naturally heightened stress response or imbalanced cortisol levels (a hormone linked to stress), can also play a role. In individuals with these biological traits, traumatic events may trigger stronger reactions, increasing the likelihood that they’ll benefit from targeted therapy for Post-Traumatic Stress Disorder.
Severity and nature of the trauma
The intensity and type of trauma will influence whether someone develops PTSD. Events that are prolonged or repeated, like combat exposure or domestic abuse, are more likely to lead to PTSD than single, isolated events. Additionally, traumatic events perceived as life-threatening or violent, such as physical assault, tend to have a more severe psychological (and neurobiological) impact. As a result, individuals exposed to such trauma are at a higher risk.
Support systems and social environment
A reliable support system can be a lifeline after trauma, potentially reducing the likelihood of PTSD. People with strong social networks may find it easier to process traumatic experiences, reducing the risk of long-term effects. Conversely, those who lack support or face isolation after trauma may feel overwhelmed and are more likely to benefit from therapy for Post-Traumatic Stress Disorder.
Trauma at a young age
When trauma occurs in childhood, it can have lasting effects on mental health. Early-life trauma can disrupt critical stages of development, making children particularly susceptible to PTSD. In these cases, PTSD treatment can be crucial to help address both the initial trauma and its long-term impacts.

If PTSD does develop, seeking help early can make a significant difference. PTSD treatment is usually provided under a Cognitive-Behavioural Therapy (CBT) framework and, in some cases, medication is also used to help manage symptoms. CBT for PTSD is a heavily researched and effective therapy that helps people to understand, reframe and process their traumatic experiences, reducing the emotional impact over time.
