Health A to Z
Post-traumatic stress disorder (PTSD) is an anxiety disorder caused by very stressful, frightening or distressing events.
Someone with PTSD often relives the traumatic event through nightmares and flashbacks, and may experience feelings of isolation, irritability and guilt.
They may also have problems sleeping, such as insomnia, and find concentrating difficult.
These symptoms are often severe and persistent enough to have a significant impact on the person’s day-to-day life.

The type of events that can cause PTSD include:
PTSD can develop immediately after someone experiences a disturbing event or it can occur weeks, months or even years later.
PTSD is estimated to affect about 1 in every 3 people who have a traumatic experience, but it's not clear exactly why some people develop the condition and others don't.

People who repeatedly experience traumatic situations such as severe neglect, abuse or violence may be diagnosed with complex PTSD.
Complex PTSD can cause similar symptoms to PTSD and may not develop until years after the event. It's often more severe if the trauma was experienced early in life as this can affect a child's development.

It's normal to experience upsetting and confusing thoughts after a traumatic event, but most people improve naturally over a few weeks.
You should visit your GP if you or your child are still having problems about four weeks after the traumatic experience, or if the symptoms are particularly troublesome.
If necessary, your GP can refer you to mental health specialists for further assessment and treatment.
PTSD can be successfully treated, even when it develops many years after a traumatic event.
Any treatment depends on the severity of symptoms and how soon they occur after the traumatic event. Any of the following treatment options may be recommended:

The symptoms of post-traumatic stress disorder (PTSD) can have a significant impact on your day-to-day life.
In most cases, the symptoms develop during the first month after a traumatic event. However, in a minority of cases, there may be a delay of months or even years before symptoms start to appear.
Some people with PTSD experience long periods when their symptoms are less noticeable, followed by periods where they get worse. Other people have constant, severe symptoms.
The specific symptoms of PTSD can vary widely between individuals, but generally fall into the categories described below.
Re-experiencing is the most typical symptom of PTSD. This is when a person involuntarily and vividly re-lives the traumatic event in the form of:
Some people have constant negative thoughts about their experience, repeatedly asking themselves questions that prevent them from coming to terms with the event.
For example, they may wonder why the event happened to them and if they could have done anything to stop it, which can lead to feelings of guilt or shame.
Trying to avoid being reminded of the traumatic event is another key symptom of PTSD. This usually means avoiding certain people or places that remind you of the trauma, or avoiding talking to anyone about your experience.
Many people with PTSD try to push memories of the event out of their mind, often distracting themselves with work or hobbies.
Some people attempt to deal with their feelings by trying not to feel anything at all. This is known as emotional numbing. This can lead to the person becoming isolated and withdrawn, and they may also give up pursuing activities they used to enjoy.
Someone with PTSD may be very anxious and find it difficult to relax. They may be constantly aware of threats and easily startled. This state of mind is known as hyperarousal.
Hyperarousal often leads to:
Many people with PTSD also have a number of other problems, including:
PTSD sometimes leads to work-related problems and the breakdown of relationships.
PTSD can affect children as well as adults. Children with PTSD can have similar symptoms to adults, such as having trouble sleeping and upsetting nightmares.
Like adults, children with PTSD may also lose interest in activities they used to enjoy and may have physical symptoms such as headaches and stomach aches.
However, there are some symptoms that are more specific to children with PTSD, such as:
It's normal to experience upsetting and confusing thoughts after a traumatic event, but in most people these improve naturally over a few weeks.
You should visit your GP if you or your child are still having problems about four weeks after the traumatic experience, or if the symptoms are particularly troublesome.
Your GP will want to discuss your symptoms with you in as much detail as possible. They'll ask whether you've experienced a traumatic event in the recent or distant past and whether you've re-experienced the event through flashbacks or nightmares.
Your GP can refer you to mental health specialists if they feel you'd benefit from treatment. See treating PTSD for more information.
Post-traumatic stress disorder (PTSD) can develop after a very stressful, frightening or distressing event, or after a prolonged traumatic experience.
Types of events that can lead to PTSD include:
PTSD isn't usually related to situations that are simply upsetting, such as divorce, job loss or failing exams.
PTSD develops in about 1 in 3 people who experience severe trauma. It isn't fully understood why some people develop the condition while others don't. However, certain factors appear to make some people more likely to develop PTSD.
There may also be a genetic factor involved in PTSD. For example, having a parent with a mental health problem is thought to increase your chances of developing the condition.
Although it's not clear exactly why people develop PTSD, a number of possible reasons have been suggested. These are described below.
One suggestion is that the symptoms of PTSD are the result of an instinctive mechanism intended to help you survive further traumatic experiences.
For example, the flashbacks many people with PTSD experience may force you to think about the event in detail so you're better prepared if it happens again. The feeling of being "on edge" (hyperarousal) may develop to help you react quickly in another crisis.
However, while these responses may be intended to help you survive, they're actually very unhelpful in reality because you can't process and move on from the traumatic experience.
Studies have shown that people with PTSD have abnormal levels of stress hormones.
Normally, when in danger, the body produces stress hormones such as adrenaline to trigger a reaction in the body. This reaction, often known as the "fight or flight" reaction, helps to deaden the senses and dull pain.
People with PTSD have been found to continue to produce high amounts of fight or flight hormones even when there's no danger. It's thought this may be responsible for the numbed emotions and hyperarousal experienced by some people with PTSD.
In people with PTSD, parts of the brain involved in emotional processing appear different in brain scans.
One part of the brain responsible for memory and emotions is known as the hippocampus. In people with PTSD, the hippocampus appears smaller in size. It's thought that changes in this part of the brain may be related to fear and anxiety, memory problems and flashbacks.
The malfunctioning hippocampus may prevent flashbacks and nightmares from being properly processed, so the anxiety they generate doesn't reduce over time.
Treatment of PTSD results in proper processing of the memories so, over time, the flashbacks and nightmares gradually disappear.
The main treatments for post-traumatic stress disorder (PTSD) are psychotherapy and medication.
Traumatic events can be very difficult to come to terms with, but confronting your feelings and seeking professional help is often the only way of effectively treating PTSD.
It's possible for PTSD to be successfully treated many years after the traumatic event occurred, which means it's never too late to seek help.
Before having treatment for PTSD, a detailed assessment of your symptoms will be carried out to ensure treatment is tailored to your individual needs.
Your GP will often carry out an initial assessment, but you'll be referred to a mental health specialist for further assessment and treatment if you've had symptoms of PTSD for more than four weeks or your symptoms are severe.
There are a number of mental health specialists you may see if you have PTSD, such as a psychologist, a community psychiatric nurse or a psychiatrist
If you have mild symptoms of PTSD, or you've had symptoms for less than four weeks, an approach called watchful waiting may be recommended.
Watchful waiting involves carefully monitoring your symptoms to see whether they improve or get worse. It's sometimes recommended because 2 in every 3 people who develop problems after a traumatic experience get better within a few weeks without treatment.
If watchful waiting is recommended, you should have a follow-up appointment within one month.
If you have PTSD that requires treatment, psychotherapy is usually recommended first. A combination of psychotherapy and medication may be recommended if you have severe or persistent PTSD.
The treatment is carried out by trained mental health professionals who listen to you and help you come up with effective strategies to resolve your problems.
The main types of psychotherapy used to treat people with PTSD are described below.
Cognitive behavioural therapy (CBT) is a type of therapy that aims to help you manage your problems by changing how you think and act.
Trauma-focused CBT uses a range of psychological treatment techniques to help you come to terms with the traumatic event.
For example, your therapist may ask you to confront your traumatic memories by thinking about your experience in detail. During this process your therapist helps you cope with any distress you feel, while identifying any unhelpful thoughts or misrepresentations you have about the experience.
Your therapist can help you gain control of your fear and distress by changing the negative way you think about your experience. For example, feeling you're to blame for what happened or fear that it may happen again.
You may also be encouraged to gradually restart any activities you've avoided since your experience, such as driving a car if you had an accident.
You'll usually have 8-12 weekly sessions of trauma-focused CBT, although fewer may be needed. Sessions usually last for around 60-90 minutes.

Eye movement desensitisation and reprocessing (EMDR) is a relatively new treatment which has been found to reduce the symptoms of PTSD.
It involves making side-to-side eye movements, usually by following the movement of your therapist's finger, while recalling the traumatic incident. Other methods may include the therapist tapping their finger or playing a tone.
It's not clear exactly how EMDR works but it may help you to change the negative way you think about a traumatic experience.
You may also be offered group therapy as some people find it helpful to speak about their experiences with other people who also have PTSD. Group therapy can be used to teach you ways to manage your symptoms and help you understand the condition.
There are also a number of charities which provide counselling and support groups for PTSD. For example:
Antidepressants such as paroxetine, sertraline, mirtazapine, amitriptyline or phenelzine are sometimes used to treat PTSD in adults.
Of these medications, paroxetine and sertraline are the only ones licensed specifically for the treatment of PTSD. However, mirtazapine, amitriptyline and phenelzine have also been found to be effective and may be recommended as well.
However, these medications will only be used if:
Amitriptyline or phenelzine will usually only be used under the supervision of a mental health specialist.
Antidepressants can also be prescribed to reduce any associated symptoms of depression and anxiety and to help with sleeping problems. However, they're not usually prescribed for people younger than 18 unless recommended by a specialist.
If medication for PTSD is effective, it will usually be continued for a minimum of 12 months before being gradually withdrawn over the course of four weeks or longer. If a medication isn't effective at reducing your symptoms, your dosage may be increased.
Before prescribing a medication, your doctor should inform you about possible side effects you may have while taking it, along with any possible withdrawal symptoms when the medication is withdrawn.
For example, common side effects of paroxetine include feeling sick, blurred vision, constipation and diarrhoea.
Possible withdrawal symptoms associated with paroxetine include sleep disturbances, intense dreams, anxiety and irritability. Withdrawal symptoms are less likely if the medication is reduced slowly.
For children and young people with PTSD, trauma-focused CBT is usually recommended.
This normally involves a course of 8-12 sessions that have been adapted to suit the child’s age, circumstances and level of development. Where appropriate, treatment includes consulting with and involving the child's family.
Treatment with medication isn't usually recommended for children and young people with PTSD.
Complex PTSD may be diagnosed in adults or children who have repeatedly experienced traumatic events, such as violence, neglect or abuse.
Complex PTSD is thought to be more severe if:
As it may take years for the symptoms of complex PTSD to be recognised, a child's development, including their behaviour and self-confidence, can be altered as they get older.
Adults with complex PTSD may lose their trust in people and feel separated from others.
The symptoms of complex PTSD are similar to symptoms of PTSD but may include:
One of the key symptoms of complex PTSD is losing trust in people. If possible, people with complex PTSD are recommended to slowly start doing regular activities such as:
It's important to try and develop some feelings of trust. It may take some time, but a trusting relationship with a therapist will help treat complex PTSD.
Treatment from a therapist may be given in three stages, described below.
One of the first steps in treating complex PTSD may involve speaking with a therapist to learn how to control feelings of distrust and lose the feeling of being 'disconnected' from friends and family.
Certain techniques, known as 'grounding' techniques, may be able to help you separate an abusive or traumatic past from the present. The aim is to make the past seem less frightening and reduce the amount of flashbacks you experience.
With time, you can begin to experience less anxiety and learn to cope with daily life.
Trauma-focused therapy may include:
These treatments may help you to control any distressing thoughts but must be approached carefully to avoid making the situation worse.
The final stage is to begin to use these skills and techniques to develop better relationships with other people.
Medication, such as antidepressants, may still be recommended if psychotherapy isn't possible or you feel unsafe.

In some exceptional cases, the vivid recollection of a trauma can cause distress many years after the incident. Andy, an ex-fire officer, describes his experience of post-traumatic stress disorder (PTSD) and how the right treatment has helped him to move on.
"The event that caused my trauma happened 20 years ago when I was a fire officer. I was in charge of an appliance at a house fire where three people had died. It was my job to take their remains out of the house.
"A few days later I became distressed and started crying and feeling upset. This strong reaction came as a shock, but I said nothing at the time. I think this was partly because I didn't want to share my emotions with anybody.
"My feelings and thoughts continued to bother me for a few weeks. After a while I decided that, because of my job, being like this was no good and I had to put these emotions to one side.
"These early responses to the trauma indicated the huge wave of feelings and sensations that would come back 17 years later in a way I couldn’t ignore.
"I was still a firefighter. I kept remembering that terrible event and the feelings it left me with, but I tried not to think about it. A few days later my colleagues and I were at another house fire. It was similar to the one in which the family had died. Suddenly, I felt as if I wasn’t there. My mind was totally occupied in a flashback of the original incident. One of my colleagues had to step in and take over from me.
"From then on I started to become distressed for no real reason. Everything seemed emotional, and I felt raw and exposed. I got easily frustrated, which made me short-tempered and angry.
"When the distress was at its worst, I had three or four flashbacks a day. I would sweat and become very nervous as I remembered the events 20 years ago. All the smells were there, and I even felt the heat of the fire moving across my face. People who saw me say that I sometimes walked about and mouthed words, but I was completely detached from my surroundings.
"That was when it became obvious that I couldn’t go on. After some time, I had a course of trauma-focused cognitive behavioural therapy with a PTSD charity called ASSIST. They helped me to understand that I had experienced something abnormal, that none of it was my fault, and that there was nothing wrong or crazy about my emotional responses.
"Talking about the fire was uncomfortable at times, but it helped me to process my memories so that they stopped reappearing as flashbacks. They have gone now, and I am able to get on with my life."
