Functional Neuroanatomy of Emotion and Its Regulation in PTSD


Posttraumatic Stress Disorder (PTSD) is devastating. PTSD causes functional, occupational, mental and physical impairment. Emotion dysregulation arising from exaggerated responses to fear or threats play a significant role in the pathophysiology of PTSD. We can increase our understanding of the neuroanatomy of the components of emotion dysregulation in PTSD using functional neuroimaging (Fitzgerald et al., 2018). With the advancements made in technology over the past 20 years, we can now analyze the clinical neuropathophysiological of PTSD. Fitzgerald et al. (2018) focuses on emotion and its regulation using functional magnetic resonance imaging (fMRI) in patients with PTSD. The study aims to determine how we can better understand what happens with patients suffering from PTSD and how they can be assisted to overcome their fears or triggers. Combining neuroanatomy and psychiatry will lead to better methodologies for treating patients and assisting them with their triggers. The study findings indicate persons with PTSD have a hyperactive amygdala and insula when responding to stimuli conveying social threats (Fitzgerald et al., 2018). There was no specificity regarding the type of stimuli that produce over-activation, indicating people with PTSD have a uniform exaggerated salience detection.

…the individual. Failure to determine what is safe and a threat can only be rectified if the clinician performs an fMRI on the patient and establishes the triggers or causes of PTSD in the patient. Using the fMRI results, treatment is then targeted at resolving the impairment, so the patient can better differentiate threats and safety. Presently, we handle PTSD using a one-size-fits-all approach, causing us to fail in treatment. While patients\' reactions might be similar, the neurophysiology of the patients is different. Therefore, we should strive to understand what happens in the patient\'s brain before we prescribe any treatment. Failure to do so results in failed treatment or symptoms, and….....
