Applying Differential Diagnosis

o prepare:

Read the case provided by your instructor for this week’s Discussion and identify relevant symptoms and factors. You may want to make a simple list of the symptoms and facts of the case to help you focus on patterns.
Read the Morrison (2014) selection. Focus on Figure 1.1, “The Roadmap for Diagnosis,” to guide your decision making.
Identify four clinical diagnoses relevant to the client that you will consider as part of narrowing down your choices. Be prepared to explain in a concise statement why you ruled three of them out.
Confirm whether any codes have changed by checking this website: American Psychiatric Association. (2017, October 1). Changes to ICD-10-CM codes for DSM-5 diagnoses. Washington, DC: Author. Retrieved from https://www.psychiatry.org/psychiatrists/practice/dsm/updates-to-dsm-5/coding-updates
By Day 3
Post a 300- to 500-word response in which you address the following:

Provide a full DSM-5 diagnosis of the client. Remember, a full diagnosis should include the name of the disorder, ICD-10-CM code, specifiers, severity, and the Z codes (other conditions that may be a focus of clinical attention). Keep in mind a diagnosis covers the most recent 12 months.
Explain the diagnosis by matching the symptoms identified in the case to the specific criteria for the diagnosis.
Identify which four diagnoses you initially considered in the case of the client, using the DSM-5 diagnostic criteria to explain why you selected these four items. In one or two sentences each, explain why three of these diagnoses were excluded.
Explain any obvious eliminations that could be made from within the neurodevelopmental spectrum.
Describe in detail how the client’s symptoms match up with the specific diagnostic criteria for the primary disorder that you finally selected for him. Note two other relevant DSM-5 criteria for that illness from the sections on “diagnostic features” and “development and course” that fit this case.

GRADING RUBIC;
1. Initial post provides an accurate diagnosis for the case. Diagnosis is correctly written. Post accurately identifies diagnostic criteria used and does an exemplary job connecting diagnostic criteria to specific examples in the case study.

Initial post may be expanded on through a subsequent post that provides an updated diagnosis based on interaction in discussion. Subsequent post provides a full diagnosis and concise explanation for the new diagnosis is more accurate than initial diagnosis.

2. Discussion posting demonstrates an excellent understanding of all of the concepts and key points presented in the text(s) and Learning Resources. Posting provides significant detail including multiple relevant examples, evidence from the readings and other scholarly sources, and discerning ideas. Posts demonstrate exemplary critical thought.

3. Postings are well organized, use scholarly tone, contain original writing and proper paraphrasing, follow APA style, contain very few or no writing and/or spelling errors, and are fully consistent with graduate-level writing style.
