Overview

PTSD is a mental health condition triggered by experiencing or witnessing a terrifying event. It involves persistent distressing memories, avoidance behavior, and heightened anxiety that interferes with daily functioning.

Understand this condition

The body's 'fight-or-flight' system becomes stuck in the 'on' position even when there is no danger. This involves the amygdala becoming overactive while the prefrontal cortex struggles to regulate emotions. Stress hormones like adrenaline and cortisol remain elevated, keeping the nervous system on high alert.

Why it happens

It happens because the brain fails to process a memory correctly, storing it as an active threat rather than a past event. Triggers can include sights, smells, or sounds that mimic fragments of the original trauma. Without treatment, the brain continues to react to the environment as if the danger is still present.

Real-world scenarios

  • People may notice they jump at the sound of a car backfiring.
  • This often appears as avoiding specific roads where an accident occurred.
  • People may notice they feel emotionally numb or detached from loved ones.
  • This often appears as severe irritability or sudden outbursts of anger.

Common vs serious explanations

Common
  • Normal short-term stress response to a difficult week.
  • Temporary grief following a recent loss.
  • General anxiety from work or life transitions.
  • Brief periods of insomnia or restless sleep.
Serious
  • Major Depressive Disorder with suicidal ideation.
  • Traumatic Brain Injury (TBI) affecting personality.
  • Severe substance use disorder causing withdrawal or psychosis.
