SECTION 1: CASE OVERVIEW & PROBLEM STATEMENT
Patient: Sheila Davis, 68-year-old female
Reason for Encounter: Dizziness
Setting: Outpatient clinic with laboratory capabilities
Clinical Problem: Sheila presents with a new episode of dizziness. In an older adult,
dizziness requires a structured assessment because it may result from a benign vestibular
disorder, medication effect, dehydration, orthostatic hypotension, cardiovascular disease,
metabolic abnormalities, or a potentially serious neurologic process.
The first clinical task is to characterize what the patient means by "dizziness":
• Vertigo: Sensation of spinning or movement
• Presyncope: Sensation of impending fainting
• Disequilibrium: Sensation of unsteadiness or imbalance
• Lightheadedness: Nonspecific feeling of being "woozy"
Key Pattern Recognition: The dizziness is triggered + positional + brief + spinning.
This pattern strongly raises suspicion for a peripheral vestibular cause, particularly Benign
Paroxysmal Positional Vertigo (BPPV).
Main Problem (1–2 clear sentences): Differential diagnosis of complex geriatric
dizziness involving vestibular, cardiovascular, and neurological etiologies. Misdiagnosis
risks catastrophic falls and unmanaged systemic pathology.
