Three conditions produce confusion in an older adult and the rubric expects you to tell them apart on paper. Delirium arrives over hours and fluctuates, dementia arrives over years and does not, and depression can imitate either while responding to neither treatment. Attention testing, deliberate instrument selection and a defended time course are where most of the available marks live in this material. What form the deliverable takes, a graded thread, a submitted paper, or one of each, depends entirely on what your section attached to it.
Treat the position of this manual as our arrangement rather than the university's. With syllabi unpublished and course guides sitting behind a login, we sequence topics the way we teach them and we say so openly. The same openness applies to scope: we draft the case write-up, the discussion post and the documentation exercise, and we stay entirely away from live encounters and from anything a clinical evaluator has to sign.
Where the points sit in a cognition case
The time course row is the one most drafts lose. Hours to days with fluctuation and a disturbed sleep cycle points one way; a slow slide across two years reported by a relative points the other, and the history establishing which one you have must appear on the page.
Attention supplies the second row and the discriminating finding. A patient who cannot hold a sequence long enough to complete a simple reversal task has an attentional deficit, and attentional deficit is the feature separating delirium from a stable dementia.
Instrument choice carries marks of its own. A brief screen answers whether cognition is impaired, a delirium assessment method answers whether the impairment is acute, and reaching for the wrong one shows immediately in the score.
Six moves that separate the three conditions
Six moves that keep a confusion case from collapsing into a single unsupported label.
-
Establish the time course before naming anything
Get a date or an event that marks the change, and get it from somebody who was there. A diagnosis argued without a timeline is a guess dressed as a conclusion, and the reasoning row watches for precisely that.
-
Test attention first, because attention decides the argument
Ask for the months backward, a digit span or a serial subtraction, and record the performance rather than your impression of it. Everything downstream depends on whether attention held.
-
Screen mood before concluding irreversible decline
Apathy, poor concentration and slowed responses belong to depression as readily as to dementia, and a geriatric mood scale takes minutes to apply and can redirect the entire plan.
-
Match the tool to the question you are actually asking
A screen for impairment, a confusion assessment method for acuity, a functional history for staging. Naming why you chose each one earns as much as the result it produced.
-
Hunt the precipitants, because delirium always has them
Infection, retention, constipation, pain, hypoxia, metabolic disturbance and above all a drug started or increased recently. Write down what you looked for as well as what you found.
-
Write the conclusion as an argument with alternatives closed
State which of the three this is, give the two findings that decided it, then say what would change your answer. That last move reads as clinical maturity and it is rarely written.
A layout for a cognitive case
Use this as an internal scaffold, not as a requirement. If your classroom supplied a note format, that format wins over anything arranged here.
| Section | What belongs in it | What the row rewards |
|---|---|---|
| Presenting change and informant | What changed, when it changed, and who noticed, with the informant's relationship stated. | A dated onset attributed to a named source rather than a general report of confusion. |
| Time course and fluctuation | The pattern across a single day and across the weeks, including the sleep cycle. | Fluctuation either demonstrated with an example or excluded with one. |
| Cognitive testing | The instrument used, the domains it covered, the score obtained and the items missed. | A test chosen for a stated reason, scored fully, and interpreted against education and language. |
| Mood and psychiatric screen | A mood instrument, plus sleep, appetite, anhedonia and any earlier psychiatric history. | Depression actively identified or excluded instead of quietly assumed away. |
| Precipitants and medication review | Infection, metabolic causes, retention, pain, and every drug started or increased recently. | A search naming what was ruled out, with anticholinergic burden addressed drug by drug. |
| Formulation and plan | The conclusion, the reasoning behind it, and what happens next in each setting. | One defended diagnosis, competing explanations closed, and a plan matched to that conclusion. |
Annotated sample excerpt: fluctuating confusion after surgery
An original passage from our writers, showing a time course argument built out of evidence.
The son reports that his father managed his own garden and his own bank account until a hip fracture repair nine days ago, and that since the second night after surgery the man has been alert at breakfast and unreachable by late afternoon.1 On testing he cannot recite the months in reverse past September and loses the thread of a two-step instruction, an attentional failure that a stable dementia would not produce and that matches the fluctuation the family describes.2 A urinary catheter still in place, oxycodone every four hours and a scopolamine patch nobody has removed supply three plausible precipitants before any imaging is even considered, which is why the working formulation is delirium superimposed on an unassessed baseline rather than new dementia.3
- 1The premorbid level is established through concrete activities and the change is dated to an event, so the time course argument rests on evidence.
- 2Attention is tested and reported as performance, then used explicitly to close the competing diagnosis.
- 3Three reversible contributors are named as specific drugs and devices, which converts a label into something a colleague can act on.

Five errors that wreck a confusion write-up
- Confusion documented without a timeline. Absent an onset and a course, the three candidate diagnoses cannot be separated and the reasoning row has nothing to reward.
- Memory tested while attention is ignored. Recall fails in all three conditions; attention is the finding that discriminates, and it is the one most often skipped.
- A screening score reported without context. Education, first language, hearing and vision all move these totals, and a bare number invites a misreading of the patient.
- Delirium named with no precipitant sought. The diagnosis carries an obligation to find the cause, and a paper stopping at the label has completed half the assignment.
- Depression left unscreened. A treatable mood disorder misfiled as early dementia is the costliest error in this material, and rubric rows exist specifically to catch it.
Final pass before upload
- Onset and fluctuation are documented from a named informant
- Attention is tested and the performance is written down
- A mood instrument was applied and its result is interpreted
- Each cognitive tool used is justified by the question it answered
- Reversible precipitants are searched by name, including anticholinergic burden
- The formulation closes at least one competing explanation
Cognitive case waiting?
Give us the scenario and whichever rubric the section uploaded this term. Original drafting on a confusion case takes 24 to 48 hours here, attention, time course and precipitants each argued on the page, and the free revision window stays open until the rows clear.
