Brain regions that are felt to play an important role in PTSD include hippocampus, amygdala, and medial prefrontal cortex. Cortisol and norepinephrine are two neurochemical systems that are critical in the stress response (Figure 1.)
Trauma is not physically held in the muscles or bones — instead, the need to protect oneself from perceived threats is stored in the memory and emotional centers of the brain, such as the hippocampus and amygdala.
Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event. Most people who go through traumatic events may have temporary difficulty adjusting and coping, but with time and good self-care, they usually get better.
People with PTSD have intense, disturbing thoughts and feelings related to their experience that last long after the traumatic event has ended. They may relive the event through flashbacks or nightmares; they may feel sadness, fear or anger; and they may feel detached or estranged from other people.
Studies have shown that PTSD actually does affect the functions of the brains in multiple ways. The effects of trauma on the brain impact three areas of the brain that are impacted the most are the amygdala, hippocampus, and prefrontal cortex. These areas all play a part in regulating emotions and responding to fear.
PTSD causes your brain to get stuck in danger mode. Even after you're no longer in danger, it stays on high alert. Your body continues to send out stress signals, which lead to PTSD symptoms. Studies show that the part of the brain that handles fear and emotion (the amygdala) is more active in people with PTSD.
Stress results in acute and chronic changes in neurochemical systems and specific brain regions, which result in longterm changes in brain “circuits,” involved in the stress response. Brain regions that are felt to play an important role in PTSD include hippocampus, amygdala, and medial prefrontal cortex.
Without treatment, the psychological symptoms of PTSD are likely to worsen over time. Along with severe depression and anxiety, other serious outcomes may include: Increased suicidal ideation. Problems managing anger and aggression.

For physical health problems, this could include labs (like bloodwork), tests (like an x-ray, scan or biopsy) or a physical exam. For PTSD, an assessment includes answering questions about your thoughts, feelings and behaviors. PTSD is most often diagnosed, or confirmed, by a mental health provider.
Criteria for Diagnosis
To receive a diagnosis of PTSD, a person must have at least one re-experiencing symptom, at least three avoidance symptoms, at least two negative alterations in mood and cognition, and at least two hyperarousal symptoms for a minimum of one month.
The main symptoms and behaviours associated with PTSD and complex PTSD include: Reliving the experience through flashbacks, intrusive memories, or nightmares. Overwhelming emotions with the flashbacks, memories, or nightmares. Not being able to feel emotions or feeling “numb”
Treatment for trauma
By concentrating on what's happening in your body, you can release pent-up trauma-related energy through shaking, crying, and other forms of physical release.
Initial reactions to trauma can include exhaustion, confusion, sadness, anxiety, agitation, numbness, dissociation, confusion, physical arousal, and blunted affect. Most responses are normal in that they affect most survivors and are socially acceptable, psychologically effective, and self-limited.
PTSD symptoms usually appear soon after trauma. For most people, these symptoms go away on their own within the first few weeks and months after the trauma. For some, the symptoms can last for many years, especially if they go untreated. PTSD symptoms can stay at a fairly constant level of severity.
If someone has PTSD, it may cause changes in their thinking and mood. They may suffer from recurrent, intrusive memories. Upsetting dreams, flashbacks, negative thoughts, and hopelessness are also common. Experiencing PTSD triggers may cause the symptoms to become worse or reoccur frequently.
Women with PTSD may be more likely than men with PTSD to: Be easily startled. Have more trouble feeling emotions or feel numb. Avoid things that remind them of the trauma.
So, does PTSD ever go away? No, but with effective evidence-based treatment, symptoms can be managed well and can remain dormant for years, even decades. But because the trauma that evokes the symptoms will never go away, there is a possibility for those symptoms to be “triggered” again in the future.
PTSD can be worsened due to the kind of trigger involved. A trigger reminds you of what happened, activating memories, emotions, and physical responses, leading to a severe reaction.
Symptoms of PTSD
Re-living the traumatic event through unwanted and recurring memories, flashbacks or vivid nightmares. There may be intense emotional or physical reactions when reminded of the event including sweating, heart palpitations, anxiety or panic.
For some, PTSD symptoms may be worse in later years as they age. Learn how as an older Veteran, you may still be affected by your past service. There are tips to find help as well. “The PTSD will hit you hardest when you retire or you're not occupied all the time.”
With PTSD, this system becomes overly sensitive and triggers easily. In turn, the parts of your brain responsible for thinking and memory stop functioning properly. When this occurs, it's hard to separate safe events happening now from dangerous events that happened in the past.
Emotional Trauma Symptoms
Psychological Concerns: Anxiety and panic attacks, fear, anger, irritability, obsessions and compulsions, shock and disbelief, emotional numbing and detachment, depression, shame and guilt (especially if the person dealing with the trauma survived while others didn't)
