Definition of Post-Traumatic Stress Disorder (PTSD)

Imagine your brain is a bit like an alarm system. Normally, this alarm system triggers in case of danger to help you react quickly. This is what happens when you pull your hand away from a hot plate or slam on the brakes to avoid a car collision. Once the danger has passed, your alarm system “resets” and returns to a state of calm.

Post-Traumatic Stress Disorder (PTSD) can develop when you experience a highly stressful or traumatic event. It’s as if this event caused a short circuit in your alarm system. Instead of resetting after the danger, your alarm system may remain activated. This means you may constantly feel stressed or in danger, even when you are safe.

Symptoms of Post-Traumatic Stress Disorder (PTSD)

Here are some of the symptoms you might experience:

  • Reliving the event: This could mean you have flashbacks where you feel like you’re reliving the traumatic event. You might also have nightmares about it.
  • Avoidance: You might start avoiding things that remind you of the traumatic event. This could include places, people, thoughts, or even feelings.
  • Hyperarousal: It’s like your alarm system is constantly on. You might have trouble sleeping, feel irritable, have difficulty concentrating, or startle easily.
  • Negative thoughts and feelings: You might have feelings of guilt or shame about the event. You might feel sad, lost, or detached from others. You might also find that you’re no longer interested in things you used to enjoy.

It’s important to know that these symptoms are a normal reaction to an abnormal and traumatic event. It doesn’t mean you’re weak or broken. It simply means your brain is trying to protect you.

Causes of Post-Traumatic Stress Disorder (PTSD)

Post-Traumatic Stress Disorder (PTSD) is typically caused by exposure to one or more traumatic events. However, not all individuals exposed to trauma necessarily develop PTSD. The causes and risk factors can be complex and multifactorial.

Treatments for Post-Traumatic Stress Disorder (PTSD)

Post-Traumatic Stress Disorder (PTSD) often requires a multifaceted approach to treatment. Treatment options may vary depending on the specific needs of each individual. Here are some of the most commonly used treatment options:


  • Cognitive-Behavioral Therapy (CBT): This is a type of therapy that aims to change harmful patterns of thinking and behavior. It can help manage symptoms by teaching you skills to cope with stress and anxiety.
  • Exposure Therapy: This approach gradually exposes you to traumatic memories in a controlled and safe environment to help you confront and understand them.
  • Eye Movement Desensitization and Reprocessing Therapy (EMDR): This therapy uses guided eye movements to help process traumatic memories.

Other treatments

  • Group Therapy: Sharing your experiences with others who have gone through similar traumatic events can be helpful.
  • Family and Friends Support: Support from your loved ones can play a crucial role in your recovery.
  • Relaxation Techniques: Some methods like meditation, yoga, or deep breathing can help manage stress.
  • Animal-Assisted Therapy: Studies have shown that emotional support provided by a pet can help some patients manage PTSD symptoms.
  • Physical Exercise: Exercise can help reduce stress and anxiety levels.


Antidepressants: Medications such as selective serotonin reuptake inhibitors (SSRIs) can be helpful in managing PTSD symptoms, including anxiety and depression.

It is essential to consult a mental health professional to assess your symptoms and develop a treatment plan tailored to your needs. Treatment may take time and often requires a combination of several of these options to be effective.
