Questions & Answers

Q: What are some common symptoms of PTSD?

Common symptoms include heightened anxiety, exaggerated startle response, trembling, excessive sweating, rapid heart rate, intrusive thoughts, negative flashbacks, nightmares, significant negative mood changes, and avoidance of trauma reminders.

Q: Why are women more likely to develop PTSD?

Women face traumas such as intimate partner violence and sexual abuse, with 50% of survivors developing PTSD. These high rates contribute to their higher likelihood of developing PTSD compared to men.

Q: How does PTSD impact the brain structures involved?

In PTSD, the prefrontal cortex becomes hypoactive, while the amygdala becomes hyperactive. The hippocampus, responsible for processing emotion and memory, also undergoes volume changes and remodeling due to constant stress hormone flooding.

Treatments for PTSD include a combination of medication (e.g., antidepressants) to regulate the body, cognitive behavioral therapy to modify thoughts and behaviors, and eye movement desensitization reprocessing to reframe trauma processing.
