Neurobiological Basis of PTSD

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after a person experiences or witnesses a traumatic event. The traumatic event can be anything that causes intense fear, helplessness, or horror.

The neurobiological basis of PTSD is not fully understood, but it is thought to involve changes in the brain’s stress response system. The stress response system is a complex network of brain structures and hormones that helps the body to cope with stress. When a person experiences a traumatic event, the stress response system is activated. This can lead to a number of changes in the brain, including:

• Increased activity in the amygdala, a part of the brain that is involved in processing fear.
• Decreased activity in the hippocampus, a part of the brain that is involved in memory formation.
• Changes in the levels of certain neurotransmitters, such as serotonin and norepinephrine.

These changes in the brain can lead to the symptoms of PTSD, such as intrusive memories, nightmares, avoidance of reminders of the trauma, and hyperarousal.

DSM-5-TR Diagnostic Criteria for PTSD

The DSM-5-TR diagnostic criteria for PTSD include the following:

• Exposure to a traumatic event that involved actual or threatened death, serious injury, or sexual violence.
• Recurrent, involuntary, and intrusive distressing memories of the event.
• Recurrent distressing dreams of the event.
• Acting or feeling as if the traumatic event were happening again (flashbacks).
• Intense psychological distress or physiological reactivity when exposed to internal or external cues that symbolize or resemble an aspect of the traumatic event.
• Persistent avoidance of stimuli associated with the trauma.
• Negative alterations in cognitions and mood associated with the trauma.
• Persistent symptoms of increased arousal (not present before the trauma).

Case Study

The case study presented in the video provides sufficient information to derive a PTSD diagnosis. The client, a 32-year-old woman named Sarah, experienced a traumatic event in which she was the victim of a violent assault. She has been experiencing a number of symptoms that are consistent with PTSD, including intrusive memories, nightmares, avoidance of reminders of the assault, and hyperarousal.

In addition to PTSD, the case study also mentions that Sarah has been diagnosed with major depressive disorder and generalized anxiety disorder. These diagnoses are also consistent with the information presented in the case study. However, it is important to note that the case study does not provide enough information to definitively diagnose these conditions.

Other Psychotherapy Treatment Options

There are a number of other psychotherapy treatment options that could be used for Sarah. One option would be cognitive-behavioral therapy (CBT). CBT is a type of therapy that helps people to identify and challenge negative thoughts and beliefs. CBT has been shown to be effective in treating PTSD.

Another option would be eye movement desensitization and reprocessing (EMDR). EMDR is a type of therapy that uses eye movements to help people to process traumatic memories. EMDR has also been shown to be effective in treating PTSD.

Gold Standard Treatments

Both CBT and EMDR are considered to be gold standard treatments for PTSD. This means that they have been shown to be effective in multiple clinical trials. Using gold standard, evidence-based treatments is important for psychiatric-mental health nurse practitioners because it ensures that patients are receiving the most effective treatment available.
