Symptoms
Symptoms fall into four groups, per the American Psychiatric Association:- Intrusion: Unwanted memories, nightmares, or flashbacks in which the event feels like it is happening again. Reminders — a sound, a smell, an anniversary date — can trigger intense distress or physical reactions such as a pounding heart.
- Avoidance: Steering clear of people, places, conversations, or reminders connected to the trauma.
- Negative changes in mood and thinking: Persistent guilt, shame, or fear; feeling detached from others; losing interest in activities once enjoyed.
- Heightened arousal: Being constantly on guard, startling easily, irritability or angry outbursts, and trouble sleeping or concentrating.
Causes and Risk Factors
Not everyone exposed to trauma develops PTSD. Risk is higher with:- Severe, prolonged, or repeated trauma: Especially trauma involving interpersonal violence.
- Earlier adversity: Prior trauma, particularly in childhood, sensitizes the stress response.
- Limited support: Lacking safe, supportive relationships after the event.
- Family history: A family background of anxiety or depression increases vulnerability.
- Ongoing stress after the event: Pain, injury, financial strain, or legal proceedings related to the trauma can make recovery harder.
Diagnosis
There is no blood test for PTSD; diagnosis comes from a careful, compassionate clinical interview, often aided by brief screening questionnaires. Because co-occurring conditions are the rule rather than the exception, your physician will also screen for depression, anxiety, and increased use of alcohol or nicotine, which many people lean on to blunt symptoms. Physical complaints — headaches, stomach trouble, a racing heart — are common in PTSD and sometimes bring people to the doctor long before the underlying cause is recognized.Treatment
PTSD is treatable, and getting help early leads to better outcomes:- Trauma-focused psychotherapy: The most effective treatment. Approaches such as cognitive processing therapy, prolonged exposure, and EMDR (eye movement desensitization and reprocessing) help the brain reprocess the memory so it loses its grip.
- Medications: SSRIs such as sertraline and paroxetine, and the SNRI venlafaxine, reduce the intensity of symptoms and treat co-occurring depression and anxiety; they are typically continued for many months once they prove effective.
- Sleep care: Nightmares and insomnia deserve direct attention, since poor sleep worsens every other symptom.
- What to avoid: Long-term sedatives such as benzodiazepines are generally not recommended for PTSD, and alcohol reliably makes symptoms worse over time.
