Why PTSD can happen years after traumatic event
If you have been through a frightening or distressing event, you might well suffer from post-traumatic stress disorder afterwards.
PTSD can be triggered by a serious road accident, perhaps a violent personal assault or a robbery, witnessing a death, a terrorist attack or a natural disaster such as a severe flood or earthquake.
Strangely, it 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 one in every three people who have a traumatic experience but it’s not clear exactly why some people develop the condition and others don’t.
Signs and symptoms
Someone with PTSD will often relive 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.
When to seek medical advice
It is normal to experience upsetting and confusing thoughts after a traumatic event, but in most people these will 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.
How PTSD is treated
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:
Watchful waiting – waiting to see whether the symptoms improve without treatment.
Psychological treatment – such as trauma-focused cognitive behavioural therapy (CBT) or eye movement dese-nsitisation and reprocessing (EMDR).
Antidepressant medication – such as paroxetine or mirtazapine.
