Briefly Explain the Neurobiological Basis for PTSD illness
The neurological underpinning for PTSD is associated with alterations in neurochemistry and endocrinology. According to the neurochemistry theory, PTSD arises from the aberrant modulation of peptide, serotonin, amino acids, and catecholamine, these neurotransmitters are in charge of controlling and embedding panic and stress reactions. Higher dopamine and norepinephrine levels trigger blood pressure and pulsate rise and a surge in startle reaction and stimulation (Abdallah et al., 2019). Furthermore, they hurt fear conditioning and the interpreting and reaction to fear recollections. The endocrine hypothesis indicates that faulty hormone regulation in the HPA axis triggers PTSD which is neuroendocrine stress reaction hub. The HPA axis is stimulated, which raises hypocortisolism and corticotropin- discharging hormone. This causes an excessive stress reaction, fear transmission, and aberrant strain encoding.
Discuss the DSM-5-TR Diagnostic Criteria for PTSD and Relate these Criteria to the Symptomology Presented in the Case Study
PTSD symptoms are classified as follows by the DSM-5: (i) intrusion, (ii) suppression of actions and feelings, (iii) negative alterations in thinking and mood, and (iv) alterations in arousal and sensitivity. The client in the case study exhibits adequate, relevant PTSD signs (Lenferink et al., 2021). Joe experiences PTSD symptoms due to being subjected to a possible injury during the vehicle accident. Through intrusive signs and unpleasant nightmares concneirng the accident, he continually re-experiences the horrific occurrence. Furthermore, Joe portrays a sustained suppression of stimuli, as evidenced by his suppression of accident recollections. He demonstrates adverse cognition and temperament changes due to the event, such as difficulty recalling critical details of the incident and heightened unfavorable opinions about the world. Furthermore, Joe's alertness and reactivity have changed significantly, as shown by furious outbursts, irritating conduct, and self-destructive conduct.
Does the Video Case Presentation Provide Sufficient Information to Derive a PTSD Diagnosis?
The video adequately covers the groundwork necessary to get a PTSD diagnosis. There is an appropriate explanation of the incidents before the incidence of trauma, followed by information about how Joe felt later: he had disturbances in cognition. He was saddened, notably when occurrences identical to the tragedy were narrated or when he got notified of the disaster. Thus, the specifics in the video case presentation give enough information on PTSD diagnosis.
