Week 1 Discussion: Initial Post
Sleeping Eleven Hours and Still Exhausted: Why I Would Call This a Depressive Episode but Leave Its Polarity Open
The Claim
The 24-year-old doctoral student in our assigned case meets the threshold for a major depressive episode, but I would not yet call it major depressive disorder. The episode is established; whether it belongs to a unipolar or a bipolar illness is not, and the history contains two features that keep that question open.
History Against Criteria
For five weeks the student has felt low most days and has stopped going to the running club that used to anchor the week, which covers the core requirement of depressed mood or loss of interest. The student sleeps ten to eleven hours and wakes unrefreshed, has gained about 3 kg from eating more in the evenings, struggles to read a paper to the end and describes feeling like "dead weight" in the lab. The student has had passing thoughts that it would be easier not to exist, with no plan. That is more than five symptoms for more than two weeks, with clear impairment: two missed lab meetings and a draft chapter untouched for a month.
The Rival Explanation
The obvious rival is not another depressive disorder. It is bipolar II disorder presenting in its depressed phase. Two details point that way. The pattern of oversleeping and increased appetite is more often reported in bipolar depression than in unipolar depression, although it is not specific. And the student mentions that a parent "had highs and lows" and took lithium, which points to bipolar illness in a first-degree relative. In a large international study of patients presenting with a major depressive episode, a substantial proportion met criteria for bipolar disorder that had not previously been diagnosed (Angst et al., 2011). The student has not described a hypomanic episode, but people rarely volunteer a period in which they felt unusually well.
A Second Rival, and What Would Change My View
There is one more thing in the history I cannot ignore. The student takes a friend's amphetamine tablets two or three days a week around deadlines. The crash after stimulant use produces exactly this picture of heavy sleep, hunger and flat mood. If the low mood is confined to the days after stimulant use, the diagnosis shifts toward a substance-related condition.
Two findings would change my position. Collateral history from someone who knows the student well, describing a period of days with little sleep, unusual energy and uncharacteristic spending, would move me toward bipolar II disorder, provided it happened when no stimulant was in use. A timeline showing that low mood appears only after stimulant days would move me away from a primary mood disorder.
So, for the class: how do you ask about hypomania in a way that gets an honest answer from someone who remembers it as the best week of their life?
Reply to Priyanka
Priyanka, the 58-year-old in your case, with panic attacks that started recently, was well argued as panic disorder. The feature I kept returning to was age at onset. A first panic attack in late middle age is unusual enough that I would want the medical explanations closed before settling on the psychiatric one. What would you need to see, perhaps an electrocardiogram during an episode or a thyroid result, before you would be comfortable that the heart and the thyroid were not the source?
Reply to Daniel
Daniel, you named generalized anxiety disorder for the college freshman and set aside social anxiety disorder because the worry covers many topics. I agree with the call. Another way to test it would be to ask what the student avoids. If the avoidance is mainly of situations involving other people's judgment, social anxiety comes back into view even when the worry sounds general. Did the case give you anything about what the freshman stops doing?

NR 547 Week 1 instructions, in plain terms
The first discussion in this diagnosis course usually asks you to take a brief case and defend a working diagnosis. Expect to be asked for the diagnosis you favor, the evidence from the case that supports it, at least one alternative and what further information you would want. State your position in the opening sentence. Attach two or three specific lines of the history to the criteria they satisfy, rather than reproducing criteria. Name a rival condition that could claim the same symptoms, and give the feature of this case that argues against it or keeps it open. Say what finding, collateral report or test result would change your mind. Close with a question about diagnostic practice. Replies should propose a different explanation for a classmate's case. Cite in APA 7.
Inside the NR 547 Week 1 example
The post begins by claiming a major depressive episode while refusing to call it major depressive disorder yet. It then ties the history to criteria: five weeks of low mood, withdrawal from a running club, ten to eleven hours of sleep, weight gain, poor concentration, guilt and passive death wishes, with missed lab meetings as impairment. The rival section names bipolar II disorder, pointing to hypersomnia, increased appetite and a parent treated with lithium, supported by a large study of undiagnosed bipolar disorder in depressed patients. A second rival, a stimulant crash, comes from nonprescribed amphetamine use. The post lists two findings that would change the call and asks how classmates ask about hypomania. Replies raise medical causes for late-onset panic and avoidance patterns in anxiety.
NR 547 Week 1 rubric: what full points look like
Marks in this opening discussion commonly go to a clearly stated diagnostic position, specific use of case evidence, consideration of alternatives, identification of information that would change the conclusion and substantive replies. A post that joins history to criteria earns more than one that recites published criteria anyone could look up. Naming a rival and the feature that argues against it is where much of the credit sits. Stating what would change your mind shows diagnostic humility and rigor. Keeping the post focused, a few hundred words with every sentence carrying evidence, reads as disciplined. Responses that offer a classmate a new explanation to test are rewarded. APA 7 citations and a professional voice round out the grading.
Common NR 547 Week 1 mistakes, and how to avoid them
Many first posts list diagnostic criteria at length and never commit to a position. State the diagnosis first. Another common weakness is supporting the diagnosis with general statements rather than specific lines from the case. Quote the history. Some writers ignore alternatives or mention them without saying why they are less likely. Name one and give the reason. Avoid claiming certainty the case does not support; if a key question is open, say which. Remember substance use and medical causes, which often supply the most important rivals. In replies, avoid simple agreement and suggest what else could explain a classmate's case. Keep the post short enough that the argument is visible, and check that each symptom you cite actually appears in the case.

NR 547 Week 1 questions, answered
Is a real patient allowed in the post?
Better not to. A supplied vignette or a composite invented for the post carries the same argument without putting identifiable clinical material on a discussion board. If your section allows a de-identified encounter, keep the age band broad, the setting generic and the timeline loose. The reasoning is what gets graded, and a constructed case can be built to show it more cleanly than a real one.
How much of the criteria should I quote?
Very little. One short phrase to anchor a point is normal practice, and beyond that the space is better spent on the sentence of history that satisfies it. Graders read the same criterion text in post after post, so a block of reproduced definition reads as filler. Cite the manual for the standard and spend your words on the match.
What if two diagnoses both fit the vignette?
Then say so and choose anyway. A post that lists both and commits to neither reads as unwilling rather than careful. Name the one you would carry into a treatment plan, give the feature that decided it, and note what you would want to know before you let go of the other. Ambiguity described precisely is a strength; ambiguity used to avoid a decision is not.
Where can I find a free NR 547 Week 1 sample paper?
The polarity-open depression post, with replies to two classmates, is shown above as the NR 547 Week 1 sample, readable in full. If your assigned case is different, send us the details and a post defending a diagnosis for it can be drafted.
What should the NR 547 Week 1 post argue?
A specific diagnostic position, tied to lines of the case, with a named rival and the finding that would change the call. The sample holds a depressive episode while keeping bipolar II open.
