Post traumatic stress disorder (PTSD), also known as shell shock or battle fatigue, occurs when the brain struggles to deal with anxious feelings and thoughts after experiencing or witnessing a traumatic event or series of events. PTSD is often associated with veterans, but 50% of all people will experience a traumatic event at least once in their lifetime, and 20% of those people will develop PTSD. 

After experiencing a traumatic event, such as being in a major car accident or being the victim of a burglary, it is entirely normal to react with shock, anger, nervousness, fear, and possibly even guilt. Typically, these reactions subside over time. However, a person may continue to experience intense feelings and have disturbing thoughts long after the trauma has passed, which interferes with their daily lives. In that case, they may have PTSD and should seek psychiatric treatment.

PTSD symptoms

PTSD is not diagnosed immediately after exposure to trauma. Rather, a person may be diagnosed with PTSD if they still experience symptoms months after a traumatic event. Mental health professionals diagnose PTSD based on the following symptoms, behaviors, and conditions as listed and defined in the DSM-5:

Re-experiencing symptoms

  • Flashbacks that cause you to feel like you are going through the event again
  • Nightmares
  • Frightening thoughts


  • Staying away from places, events, and objects that serve as reminders of the trauma. A car accident might cause you to stop driving, for example.
  • Avoiding thoughts and feelings associated with the trauma. For example, you might try to stay busy to avoid thinking about what happened.

Alterations in cognition and mood

  • Being easily startled
  • Feeling tense or "on edge"
  • Having difficulty sleeping
  • Having angry outbursts

Alterations in arousal and reactivity

  • Trouble remembering important things about the traumatic event
  • Negative thoughts about yourself or the world
  • Feelings of guilt and self-blame
  • Loss of interest in something you enjoyed
  • Difficulty concentrating

These symptoms can lead to significant impairment in a person’s life, whether socially, professionally, or otherwise, and may require psychiatric treatment.

Treatment options for PTSD

Psychological and biological reactions to trauma can be intense and painful. Some people live their lives with few or no symptoms, while for others, the intensity and pain persist. Traumatic psychological wounds can be challenging to treat with medication alone, so the most effective treatment usually involves both medication management and psychotherapy.

How Talkiatry treats PTSD 

Medication management

Talkiatry may recommend medication management as a tool to help manage your reaction to trauma. Medication can help people dealing with PTSD control and relieve their symptoms, allowing them to participate more effectively in psychotherapy.

Antidepressants, including SNRIs and SSRIs (selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors), are commonly used to treat PTSD. Talkiatry may also prescribe medications to manage anxiety, physical agitation, nightmares, and sleep disorders.


Typically, our PTSD specialists will recommend the use of medications alongside various psychotherapy treatments, such as:

  • Cognitive-behavioral therapy (CBT). This form of talk therapy can help you understand your feelings, process the traumatic event, and change your negative thinking patterns. 
  • Exposure therapy. During exposure therapy sessions, patients will relive aspects of trauma in a safe environment to help desensitize and break patterns of avoidance and fear. 
  • Eye Movement Desensitization and Reprocessing (EMDR). Our PTSD specialists may recommend this trauma-specific therapy to relieve anxiety and stress caused by trauma. EMDR therapy involves briefly exposing patients to traumatic memories while simultaneously focusing on an external stimulus, such as combining the patient's eye movements with the therapist's hands.

With PTSD, the risk of developing a depressive disorder is three to five times greater. Therefore, we encourage you to take our online assessment to match with one of our psychiatrists who has experience treating your diagnosis.
