PTSD is a treatable disorder. The commonly used treatments include short terms of psychotherapy and medications. Cognitive behavior therapy is the most effective psychotherapy for people with PTSD because it treats patients with short and long-term PTSD. The approach involves identifying factors triggering the disorder, comprehending them, and changing thinking and behavioral patterns. The component of the therapy includes exposure therapy and cognitive restructuring (Shubina, 2015). Other treatments for PTSD include present-centered therapy and Eye movement desensitization reprocessing, but for William, the best-preferred therapy will be CBT (Shubina, 2015). There are various medications used to treat patients with PTSD. However, medications are used as the adjunct to the therapies include selective serotine reuptake inhibitors, which are antidepressants used to depress PTSD moods (Kamo et al., 2016). The current FDA approved medications for treating PTSD are Zoloft and paroxetine (Kamo et al., 2016). However, benzodiazepines are fast-acting medicines used to treat PTSD but have side effects and treat short-terms PTSD. And thus, Zoloft, combined with CBT, would be preferred therapeutic approach for William Thompson. Expected outcomesThe expected outcome after treatment is that the client will be able to shoe improvement at every stage of medication and therapy. Zoloft works by preventing serotine intake in the nervous system, which leads to an increased serotonin concentration in the nerve synapse. Therefore, since Zoloft dose is started at small doses and continue to increase based on patient response, the expected outcome is that after every stage e.g., after four weeks the client will reduce some of the symptoms up to the end of medication where the patient will reduce all the symptoms (Kamo et al., 2016). The CBT will help the client to adopt a coping mechanism that will help him to reduce stress linked to past traumatic events and how to quit abusing alcohol (Shubina, 2015). Therefore, the outcome would be that the combination of Zoloft antidepressant and CBT will effectively treat William Thompsons health condition.
