Bipolar II edges out major depression once a partner's account of a [five]-day elevated stretch is credited, and the MN661 Unit 3 differential shows why four other candidates fall away. Searches like "mn 661 unit 3 assignment example", "mn661 unit 3 sample" and "mn661 unit 3 example" land here.
What a finished MN661 Unit 3 differential diagnosis paper looks like
Roughly five pages, built as a ranked list, not an essay. A half-page case summary comes first, with the partner's collateral account set apart from her own. Six candidates then appear in order of likelihood: bipolar II disorder, major depressive disorder, cyclothymic disorder, bipolar I disorder, a substance-induced mood disorder and borderline personality disorder. Each receives a short block in three parts: the case for it, the case against, and the single finding that decides it. The spring episode decides the first two, since four consecutive days is the hypomania floor, and five days of reduced sleep, rapid speech, surging activity and heavy spending, observed by someone else, clears it. Bipolar I falls because nothing suggests marked impairment or hospitalization; cyclothymia because the pattern is episodic rather than two years of fluctuation. A closing paragraph lists the information still wanted.
How a MN661 Unit 3 example is structured
Ranking is the organizing decision, and the paper states its basis at the top: fit with reported features first, then base rate. Every block uses the same three headings, so a reader comparing candidates can read straight across the page. The deciding finding for each is a single sentence with its source named, patient, partner or record. The Mood Disorder Questionnaire (Hirschfeld et al., 2000) appears once, described as a screen that raised the question rather than evidence that answered it. Personality disorder is handled with care: mood shifts lasting hours and set off by conflict would support it, and the case describes neither, so it is set aside without implying anything about her character. In the final paragraph, what would confirm the leading diagnosis is kept apart from what would overturn it, so the conclusion stays a working position.
Collateral set apart
The partner's account sits in its own paragraph with its source named. Elevated periods are often recalled more clearly by others than by the person who lived them, so separating the two voices allows each to be weighed on its own.
Six candidates, one order
Candidates are ranked by fit, then by base rate, and that rule is stated before the first block. A reader can dispute the order and still see precisely what reasoning produced it.
The four-day floor
Hypomania requires a distinct period of at least four consecutive days. The paper counts the spring episode against that floor and lists the four accompanying symptoms observed, which is the point where bipolar II overtakes major depression.
What each rejection rests on
Cyclothymia fails on pattern, bipolar I on severity, the substance-induced option on exposure history. Every rejection names the missing feature, so no candidate simply vanishes from the page between one paragraph and the next.
Confirm or overturn
The last paragraph lists what would strengthen bipolar II, such as a prospective mood chart or a second observer, and what would overturn it, such as stimulant use last spring. The diagnosis ends as a working position, not a closed file.
Where marks go in MN661 Unit 3
Differentials in this unit are judged on their dismissals more than on the winner. A paper naming bipolar II correctly but dropping cyclothymia and borderline personality disorder without a reason reads as a guess that happened to land. Missing the collateral account, or mentioning it without asking how many days the spring episode lasted, costs heavily, because duration is what separates hypomania from a productive week. Treating a positive Mood Disorder Questionnaire as a diagnosis draws a comment about screening versus assessment. Graders also deduct when bipolar I is dismissed on the wrong ground, such as the absence of psychosis alone. Lesser losses come from ranking with no stated rule, from a medical rule-out such as thyroid function never considered, and from wording that implies a judgment about her personality.

MN661 Unit 3 questions, answered
How many diagnoses belong in a differential?
Enough to cover the plausible alternatives, usually four to six in a case like this. A list of twelve with a sentence each is weaker than five examined properly. Include at least one medical or substance-related cause where the case permits it, since those are the rule-outs graders notice when missing, and give every candidate a reason for its place.
Can collateral information outweigh what the patient reports?
It can supplement it, and for hypomania it often matters more. People frequently remember elevated periods as productive rather than unusual. The paper should present both accounts, say where they differ, and explain which bears more weight on the specific question. Collateral from a composite partner in a supplied case is evidence the prompt expects you to use.
Should the differential include treatment?
Only when the prompt requests it. This unit is about what the presentation is, and a treatment plan appended to the differential dilutes the argument. If the prompt does request next steps, keep them to further assessment, such as a mood chart or a collateral interview, rather than prescribing anything, and leave therapy selection for a later assignment.
