PTSD (Post-Traumatic Stress Disorder)
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.
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.
