Section 1: Executive Case Summary
Patient Identification: Ms. Sophia King, a 79-year-old Caucasian female, accompanied by her daughter,
presents to the outpatient clinic via urgent referral due to acute-on-chronic mental status changes, acute
disorientation, visual hallucinations, and progressive memory worsening over the past 48 to 72 hours.

,five core domains:
1. Differential Diagnosis of Acute Encephalopathy: Distinguish between primary neurodegenerative dementia, acute
delirium secondary to systemic illness, and metabolic/medication-induced encephalopathy in a vulnerable geriatric host.
2. Structured Geriatric History Acquisition: Execute a targeted, informant-assisted history using standardized operational
frameworks (OLD-CARTS) to establish precise temporal onset, baseline functional status, and toxicological exposures.
3. Evidence-Based Multi-System Examination: Apply specialized clinical bedside maneuvers (including mini-cognitive
scoring, Confusion Assessment Method [CAM], and focused neurological/urological physical exams) to detect subtle
organic pathology.
4. Diagnostic Synthesis & Lab Interpretation: Interpret emergency laboratory panels, geriatric urinalysis, inflammatory
markers, and neuroimaging modalities to isolate the primary triggers of delirium.
5. Holistic Management & EHR Documentation: Formulate an evidence-based, pharmacologically safe inpatient
management plan including fluid resuscitation, antimicrobial stewardship, avoidance of inappropriate medications (Beers
Criteria), and clear discharge planning.
CLINICAL PEARL: DELIRIUM VS. DEMENTIA
Delirium is a medical emergency characterized by acute onset, fluctuating course, inattention, and altered level of
consciousness. Unlike dementia, which is insidious and chronic, delirium is frequently reversible if the underlying
organic etiology (such as infection, dehydration, or electrolyte imbalance) is rapidly identified and treated.

responses from the patient and her primary caregiver (daughter), along with the diagnostic rationale for each
inquiry.

CRITICAL DIAGNOSTIC ALERT
Elderly patients frequently present with non-specific functional or cognitive decline rather than classic localized
symptoms (such as high fever or flank pain) during severe acute infections.
