What PTSD is
Post-traumatic stress disorder (PTSD) can develop after experiencing or witnessing a serious threat: violence, accidents, robberies, disasters, severe illness or the sudden death of someone close. Not everyone exposed develops it; individual factors and support play a role.
Signs and symptoms
- Re-experiencing: intrusive memories, nightmares, feeling the event is happening again
- Avoidance of places, people, conversations and thoughts linked to the trauma
- Changes in mood and thinking: guilt, fear, detachment, difficulty feeling positive emotions
- Hyperarousal: being easily startled, irritability, insomnia, poor concentration, a constant sense of danger
How it is diagnosed
The psychiatrist assesses the event, the duration and intensity of symptoms and their impact. The assessment respects the patient’s pace: you do not need to describe every detail at the first appointment. Depression, anxiety, insomnia and alcohol or drug use, which often accompany PTSD, are also evaluated.
Treatment
- Trauma-focused psychotherapies, the foundation of treatment
- Medication, when indicated, for anxiety, insomnia, nightmares and depression
- Sleep care and gradual return to avoided activities
When to see a psychiatrist
If, more than a month after the event, symptoms remain intense, you avoid important situations, or sleep, work and relationships are affected. Thoughts of death need immediate help: in Brazil, call 188 (CVV).
Follow-up at the practice
At the practice in Campinas, Dr. Petrus Raulino conducts the assessment discreetly and at the patient’s pace, defines the treatment plan and, when needed, coordinates with trauma-focused psychotherapy.
