Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop after experiencing or witnessing a traumatic event. After trauma, it's normal to feel shaken for a while; most people gradually recover over a few weeks. But when the distress persists for longer— typically more than a month— and disrupts daily life, it may be PTSD. It tends to show up in four ways: reliving the event (flashbacks, nightmares), avoiding reminders, persistent negative thoughts and mood, and being constantly on edge. PTSD is not a sign of weakness— it's a recognised condition, and importantly, it is highly treatable. With the right support, people recover.
After any traumatic event, it's normal to experience upsetting memories, trouble sleeping, or difficulty with daily activities. For most people, these feelings ease over a few weeks as they return to their usual routine. But when the distress lingers for more than a month or so, and continues to interfere with daily life, it may be Post-Traumatic Stress Disorder. Understanding what PTSD is— and that it can be treated— is an important first step toward getting help.
What is PTSD? PTSD is a stress-related condition in which a person, after a traumatic experience, keeps re-experiencing the event— through flashbacks, intrusive memories, or nightmares— in a way that triggers intense anxiety and makes it hard to function. The traumatic memories feel vivid and inescapable, as though the person is stuck reliving the moment.
What causes PTSD?
PTSD can develop after experiencing or witnessing any deeply distressing or life-threatening event— for example a serious accident, physical or sexual assault, abuse, a natural disaster, the sudden loss of a loved one, a medical emergency, or combat. It can also follow learning that a traumatic event happened to someone close to you. Not everyone who goes through trauma develops PTSD— many factors influence it— but when the distress doesn't fade, support is warranted.
Symptoms of PTSD
PTSD generally shows up across four broad areas. A person may experience symptoms from each, to differing degrees.
Reliving the event (flashbacks)
A person with PTSD may relive the traumatic moment again and again— through intrusive memories, distressing nightmares, or vivid flashbacks. These can feel so real that they seem stuck in the moment, and they bring back the fear and distress of the original event.
Avoidance
To escape that distress, a person may start avoiding anything that reminds them of the event— particular places, situations, people, or even conversations about what happened. This avoidance can narrow their world over time and make the difficulty harder to address.
Negative thoughts and mood
PTSD often brings persistent negative thoughts and feelings— guilt, shame, or a bleaker outlook on the world. A person may find it hard to trust themselves or others, struggle to feel positive emotions, and feel increasingly detached or low.
Being constantly on alert
Many people with PTSD feel perpetually on guard, scanning for danger. This state of heightened alertness can disrupt sleep and concentration, and leave a person feeling vulnerable, tense, and easily irritated or startled much of the time.
Conditions that can occur alongside PTSD
PTSD often doesn't come alone— other difficulties can accompany it, including:
- Depression or anxiety
- Alcohol or substance use, as a way of coping
- Persistent guilt, shame, hopelessness, or despair
- Physical symptoms such as headaches or stomach pain
- Difficulties in relationships
- Difficulties at work
Symptoms often begin soon after the event, but they can also surface months or even years later. They may come and go, but left unaddressed they tend to keep interfering with daily life— which is why seeking support matters.
PTSD is treatable
This is the most important thing to know: PTSD is not a sign of weakness, and it is not something a person simply has to live with. It is a recognised condition that responds well to treatment. Trauma-focused psychological therapies— including Cognitive Behavioural Therapy (CBT) and other evidence-based approaches— help people process the traumatic memories, reduce the symptoms, and reclaim their lives, often within months. Where helpful, a doctor may also consider medication. With the right professional support, recovery is genuinely possible.

Frequently asked questions
How is PTSD different from normal stress after a traumatic event?
It's normal to feel shaken, have trouble sleeping, or struggle with daily life for a while after trauma— and for most people this eases over a few weeks. PTSD is when those symptoms persist (typically beyond a month), remain intense, and keep interfering with daily life. The key differences are how long it lasts and how much it disrupts functioning.
Can PTSD symptoms appear long after the event?
Yes. While symptoms often begin soon after the traumatic event, they can also surface months or even years later— sometimes triggered by a reminder or a later stress. Delayed-onset PTSD is still PTSD and still treatable, so it's worth seeking support whenever the symptoms appear.
Is PTSD a sign of weakness?
No. PTSD is a recognised mental health condition, not a character flaw or a failure of willpower. It can affect anyone who has experienced or witnessed trauma. Seeking help for it is a courageous and sensible step— and an effective one, because PTSD responds well to treatment.
Can PTSD be treated?
Yes, very effectively. Trauma-focused therapies such as CBT help people process traumatic memories and reduce symptoms, often within months, and medication may help in some cases. Many people recover and reclaim their quality of life with the right professional support. PTSD is not something you simply have to endure.
